Problem

Which of the following equations represents a line that passes through the

points (-3, -14) and (0, –2)?

Solution

For this case we want to create an equation with this general form:

y= mx+b

We can calculate the slope with this operation:

And the intercept can be founded with the second point:

-2= 4(0)+b

b= -2

And the equation would be:

y= 4x -2

If we analyze the second option given we can see that we can write like this:

y-6 = 4(x-2)

y-6= 4x-8

y-6+8 =4x

y+2= 4x

y= 4x-2

So then the best option would be:

II. y-6 = 4(x-2)

Answer:

  (d)  The triangles are similar, because each has angles that measure 36°, 62°, and 82°.

Step-by-step explanation:

Given triangle A has angles 36° and 82°, and a figure showing angles related to triangle B, you want to know if the triangles are similar.

The triangles will be similar if the angles of one are congruent to the angles of the other. Between the two triangles, we are given 3 different angle values, so we need to find at least two additional angle values in order to determine if the triangles are similar.

The sum of angles in a triangle is 180°, so the third angle of triangle A will be ...

  angle = 180° -36° -82° = 62°

The exterior angle of triangle B, given as 144°, is the sum of the remote interior angles:

  144° = 62° +angle

  82° = angle

Now, we have the angles of triangle A as 36°, 62°, and 82°. Two of the angles of triangle B are known to be 62° and 82°, matching those of triangle A.

The triangles are similar, because each has angles that measure 36°, 62°, and 82°.

The measure of angle TRS would be of 37º.

The vertices of the triangle can be attributed freely, hence we attribute as is in the drawing.

The altitude RT bisects the triangle forming a right angle, with R and T, hence the internal angles of the triangle TRS are as follows:

The sum of the measures of the internal angles of a triangle is of 180º, hence the measure of the missing angle TSR can be found as follows:

43 + 90 + x = 180

133 + x = 180

x = 180 - 133

x = 47º -> m<TSR = 47º.

I(-1,0)

After a translation, the figure becomes the red one, with the following points:

C'(1,2)

G'(0,-1)

Q'(3,-4)

I'(4,1)

You can notice that each x' coordinate of the new figure is respecto the previous figure:

x' = x + 5

Furthermore, for y':

y' = y +1

That is, the transformation applied to the figure (black lines), is:

Angle

When two straight lines intersect, an angle is formed. The point of intersection is called the vertex of the angle and the lines are called the arms of the angle.

Vertically opposite angle

The angle formed by two intersecting straight lines and are opposite to one another at a specific vertex is called vertically opposite angle.

Vertically opposite angles are equal.

Given the following question:

The principal wants to estimate the percentage of students in the school who play video games, which is a good number of students. Selecting 30 random students and asking them if they play video games can represent the entire school. Asking 30 random students keeps it from being biased for example option B, asking 30 students who take coding classes is biased because they are in one specific class, they do not represent the majority of the school unless the school is a coding school.

The answer is the first option because it is a random sample of people to represent a population of people. This keeps the results from being biased so asking 30 random students is the way to go.

The distances that the footballs travel before hitting the ground is 50 yards.

For the given question;

The football is kicked by the player.

The second kick is modeled by f(x) = -0.051x(x - 50).

Where, f is the height (in yards) and x is the horizontal distance (in yards).

For calculating the distances that the footballs travel before hitting the ground, Put f(x) = 0.

As, the ball will reach the ground the height of ball above ground will be zero, thus f(x) = 0.

f(x) = -0.051x(x - 50) = 0

Simplifying;

-0.051x² + 2.25x = 0

Or, divide wole equation by x.

0.051x = 2.25

x = 50 yards.

The linear inequality that is represented by the graph is y ≤ x/3 - 4. The correct option is the second option y ≤ x/3 - 4

From the question, we are to determine the linear inequality that is represented by the graph

First, we will determine two points on the line

The line in the graph passes through (0, -4) and (3, -3)

Using the equation,

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

(y - -4)/(x - 0) = (-3 - (-4))/(3 - 0)

(y + 4)/x = (-3 + 4)/3  

(y + 4)/x = 1/3

y + 4 = 1/3x

y = 1/3x - 4

y = x/3 - 4

This is the equation of the line

In the given graph, the line is a solid line and the solution of the inequality is below the line

Answer:7719

Step-by-step explanation:

We need to examine each expression at a time.

(A) x^2 + x - 6

notice the -6 has factors 3 and -2 which could be used to reverse the FOIL method:

x^2 + x - 6 = x^2 + 3 x - 2 x - 6 = x( x + 3) - 2 (x + 3) = (x+ 3) (x - 2)

(B) In this cubic expression we cannot use the reverse FOIL to extract factors.

(C) 4 x^2 - 2 x + 1 We cannot reverse the FOIL property either.

(D) x^2 + 8 x + 12

We notice that 12 has factors 2 and 6 which can be used to factor out this expression as shown below:

x^2 + 2 x + 6 x + 12 = x (x + 2) + 6 (x + 2) = (x + 2) (x + 6)

Therefore we were able to use the reverse of the FOIL property in expressions (A) and (D).

Im unsure what your asking but the answer is 6 1/2 in fraction form and 6.5 in decimal form :/

Step-by-step explanation:

math

When 117 is divided by 18 we get 117/18 in fraction form.

To divide 117 by 18, we perform long division.

We start with the first digit of the dividend (1) and divide it by the divisor (18).

Since 18 is larger than 1, the quotient for this step is 0.

We then bring down the next digit (1) and place it next to the previous result.

Again, since 18 is larger than 11, the quotient for this step is 0.

Therefore, the result of dividing 117 by 18 is 0 with a remainder of 117.

In fraction form, this can be expressed as 117/18.

3To calculate the test statistics, we use the following steps:

Step 1: We write out the parameters

Step 2: Write out the formula for the test statistics (t)

step 3: Find t

Hence, the test statistic is approximately 0.98 to two decimal places.

Answer:

Solutions below.

Step-by-step explanation:

This question tests on the concept of graph reading.

To find the slope of a line, we have to use the following formula:

[tex] \frac{y2 - y1}{x2 - x1} [/tex]

Now, we can pick 2 random points on the line to substitute the values in to find the slope.

We will pick

(0, 3) as (x1, y1)

and

(2,0) as (x2, y2)

Therefore the slope will be:

[tex] \frac{0 - 3}{2 - 0} \\ = \frac{ - 3}{2} \\ = - \frac{3}{2} [/tex]

Now to find the y-intercept, as the name suggests, it is the point where the line intercepts the y-axis (vertical axis) , in this case, it is 3.

The point of this intercept is (0,3).

Answer:

Step-by-step explanation:

You want the slope and the y-intercept of the line shown in the graph.

The slope is the ratio of "rise" to "run". It is best found by identifying points on the graph where the line crosses grid intersections. The attachment shows two of those: (0, 3), (3, -2).

You can count grid squares or use the slope formula to find the slope.

  slope = rise/run = (y2 -y1)/(x2 -x1)

  slope = (-2 -3)/(3 -0)

  slope = -5/3

The y-intercept is the y-value of the point where the line crosses the y-axis. We have already found that to be 3, at one of the points used to find the slope.

  y-intercept = 3 . . . . point (0, 3)

The rate at which the area of this square increases when the area of the square is 9 cm is 24 cm²/s.

The rate of change is a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the area of a square can be calculated by using this formula;

A = s²

Where:

Next, we would determine the side length of a square by making s the subject of formula as follows:

A = s²

s = √A

s = √9

s = 3 cm.

By applying chain rule of differentiation, the rate of change (da/dt) in area of this square with respect to time is given by:

dA/dt = 2 × s(t) × ds/dt

dA/dt = 2 × 3 × 4
