Answer:
False
Step-by-step explanation:
Here's a simple little trick to tell wether a system of inequalities has any solutions or not, just by looking at it:
If the slopes are the same but the y-intercepts are different, the system has no solutions. If the slopes are different, the system has only one solution. If the slopes are the same and the y-intercepts are the same, then the system has infinitely many solutions.By following this logic, since the system given has different slopes, it only has one solution. Therefore your answer is false.
Hope this helps you.
The equation y + 6 = one-third (X minus 9) is written in point-slope form. What is the equation written in slope-intercept form? y = one-third x minus 3 y = one-third x + 9 y = one-third x minus 9 y = one-third x + 3
The equation written in slope-intercept form is y = (1/3)x -9
What is a linear Equation ?A linear equation is that which can be represented in the form of y =mx +c , m is the slope and c is the intercept.
The given equation is
y+6 = 1/3(x-9)
To determine the slope and the intercept this equation needs to be solved
y+6 = (1/3)x - 3
y = (1/3)x -9
Therefore this is the slope intercept format , here
the slope = 1/3
intercept = -9

Answer:
E. 38°
Explanation:
A rhombus has 360° interior angle.
Half of the other side has 180° angle.
Solve for x:
sum of interior angles = 180°
x + 14 + x + 14 + x + x = 180°
4x + 28° = 180°
4x = 180° - 28°
4x = 152°
x = 152°/4 = 38°
Sum of half interior angles=180°
So
x+x+14+x+x+14=1802x+2(x+14)=1802x+2x+28=1804x+28=1804x=152x=38°Option E
Use the points (0, 4) and (-2, 3) to find the slope of the line and give the equation of this line.
Answer:
Choice C: [tex]m=\frac{1}{2}; y=\frac{1}{2} x+4[/tex]
Step-by-step explanation:
To find your slope do:
[tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
[tex]\frac{3-4}{-2-0}=\frac{-1}{-2} =\frac{1}{2}[/tex]
that's how you get 1/2
4 is just the y-int.
The required equation of line passes through (0, 4) and (-2, 3), has slope of m = 1/2 , is y = 1/2x + 4. Option C is correct.
What is the equation?The equation is the values of two expressions that are equal.
What is the slope of the line?The slope of the line is the tangent angle made by the line with horizontal. i.e. m =tanx where x in degrees.
The slope of the equation line passing through (0, 4) and (-2, 3)
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m = (3 - 4) / (-2-0)\\m = -1/-2\\m = 1/2[/tex]
Strand form of the equation of the line,
[tex]y-y_1 = m(x-x_1)[/tex]
Putting values in the standard form of the equation of the line.
y - 4 = 1/2 * (x - 0)
y = 1/2 * x + 4
[tex]y = \frac{1}{2} x + 4[/tex]
Thus, the required equation of line passes through (0, 4) and (-2, 3), has slope of m = 1/2 , is y = 1/2x + 4. Option C is correct.

Jace gave $100 to her daughter Kailey and asked her to spend three parts and save two parts of the total amount. How much did Kailey spend and how much did she save?
Step-by-step explanation:
spending 3 parts and saving 2 parts means that there are 3+2 = 5 parts in the whole.
the whole being $100.
one of the 5 parts is then 100/5 = $20.
so, she spent 3×20 = $60 and saved 2×20 = $40.
Part 3 - Discussion/Explanation Question
In what ways can vertical, horizontal, and oblique asymptotes be identified? Use a mathematical example to
explain the ways.
Step-by-step explanation:
Vertical asymptote can be Identites if there is a factor only in the denominator. This means that the function will be infinitely discounted at that point.
For example,
[tex] \frac{1}{x - 5} [/tex]
Set the expression in the denominator equal to 0, because you can't divide by 0.
[tex]x - 5 = 0[/tex]
[tex]x = 5[/tex]
So the vertical asymptote is x=5.
Disclaimer if you see something like this
[tex] \frac{(x - 5)(x + 3)}{(x - 5)} [/tex]
x=5 won't be a vertical asymptote, it will be a hole because it in the numerator and denominator.
Horizontal:
If we have a function like this
[tex] \frac{1}{x} [/tex]
We can determine what happens to the y values as x gets bigger, as x gets bigger, we will get smaller answers for y values. The y values will get closer to 0 but never reach it.
Remember a constant can be represent by
[tex]a \times {x}^{0} [/tex]
For example,
[tex]1 = 1 \times {x}^{0} [/tex]
[tex]2 = 2 \times {x}^{0} [/tex]
And so on,
and
[tex]x = {x}^{1} [/tex]
So our equation is basically
[tex] \frac{1 \times {x}^{0} }{ {x}^{1} } [/tex]
Look at the degrees, since the numerator has a smaller degree than the denominator, the denominator will grow larger than the numerator as x gets larger, so since the larger number is the denominator, our y values will approach 0.
So anytime, the degree of the numerator < denominator, the horizontal asymptote is x=0.
Consider the function
[tex] \frac{3 {x}^{2} }{ {x}^{2} + 1} [/tex]
As x get larger, the only thing that will matter will be the leading coefficient of the leading degree term. So as x approach infinity and negative infinity, the horizontal asymptote will the numerator of the leading coefficient/ the leading coefficient of the denominator
So in this case,
[tex]x = \frac{3}{1} [/tex]
Finally, if the numerator has a greater degree than denominator, the value of horizontal asymptote will be larger and larger such there would be no horizontal asymptote instead of a oblique asymptote.

∠ KGH is equal to 77°. This is arrived at by using the knowledge of the total angles in Parallel Lines.
What are the total angles on a straight line?
According to the laws of lines and angles, the total number of angles that can exist on a straight line is 180°.
If ∠CED = 25° and ∠BFL = 78°, then: ∠KGH = 180-(25+78), which is equals 77°. This is because the total angles on a straight-line total 180°
What is ∠LKJ?Recall that in angles in parallel lines:
Corresponding Angles are always congruent, Alternate Angles are always congruent, and Interior According always sum up to 180°Hence,
We can derive ∠LKJ because it is congruent with ∠BGJ.
To get ∠BGJ, we must get ∠LFH because both of them are interior angles and sum up to 180°.
To get ∠LFH, we must subtract ∠BFL from 180° because they are both angles on a straight line.
Hence ∠LFH = 180 - 78 = 102°
Recall that ∠LFH and ∠BGJ are interior angels. Hence
∠BGJ = 180 - 102 = 78°.
Since ∠BGJ is a corresponding ∠ with ∠LKJ, therefore
∠LKJ = 78°
What is ∠ALM?
∠ALM is ∠BFL because they are both corresponding angles and are therefore congruent.
What are the solutions to section B?Because ∠ACB and ∠BAC are equal, therefore sides AB and BC are equal in length. We can tell that ∠ACB and ∠BAC are equal because the total angles in the triangle are equal to 180°2. The name given to the triangle mentioned above is Obtuse

What are the domain and range of g(x)= √x-3?

B. D: [–3, ∞) and R: [0, ∞)
C. D: (–3, ∞) and R: (–∞, 0)
D. D: (3, ∞) and R: (–∞, 0)
Answer:
I guess, A is the wanted answer, but
A and D together are the really correct answer.
Step-by-step explanation:
if I understand this correctly, then
g(x) = sqrt(x - 3)
the domain of a function is the definition of all valid x (input) values.
the range of a function is the definition of all valid y (result) values.
well, the content (the arguments) of a square root cannot be negative (at least not while dealing with real numbers).
so, the answer options B and D are automatically out, because the domain contains values that would make the arguments of the square root negative.
I guess your teacher wants to focus only on the positive results of the square root, so A is the correct number.
BUT formally, without designated restrictions, a square root has always 2 solutions : a positive and a negative one.
because (-x)² = (x)² = x².
so, I would have to say that the really correct answer is
A + D, because the range contains both, the positive and the negative numbers.

the ratio of the length of an arc of the circle to the circumference of the circle is 3:7, if the diameter of the circle is 14cm calculate to three significant figures the (a) perimeter of the minor circle (b) area of the minor circle, take thither=22/7
The perimeter and area of this minor circle are equal to 32.857 units and 88.345 units² respectively.
How to calculate the perimeter of the minor circle?First of all, we would determine the circumference of this circle by using this formula:
C = πD
C = 22/7 × 14
C = 44 units.
For the length of an arc of the circle:
Arc length/Circumference = 3/7
Arc length = 3/7 × C
Arc length = 3/7 × 44
Arc length = 18.857 units.
Now, we can calculate the perimeter:
Perimeter = 2r + arc length
Perimeter = 2(14/2) + 18.857
Perimeter = 14 + 18.857
Perimeter = 32.857 units.
The area of the minor circle.Mathematically, the area of a minor circle is given by this formula:
Area = θr²/2
But, we would have to find the angle in radians:
18.857/32.857 = θ/360
θ = 3.6059 radians.
Substituting the given parameters into the formula, we have;
Area = (3.6059 × 7²)/2
Area = 88.345 units².

Which could be the entire interval over which the function, f(x), is positive?
Why?
Notice that f(x) is positive when -2 < x < 1. In other words, f(x) is positive when x = -1 and when x = 1.
This interval of -2 < x < 1 translates directly to the interval notation of (-2, 1)
Unfortunately this interval notation looks identical to ordered pair notation. Be sure not to mix the two concepts up.
The parenthesis in interval notation tell the reader "do not include the endpoints". We cannot include x = -2 nor x = 1 because these values make f(x) zero, but we want f(x) > 0.
Something like choice D is a non-answer because the value x = 2 is in the interval (1,4), but f(2) = -8 which isn't positive. We can rule choice D out because of it. Choices A and C are similar situations.
