Here is a system of equations. y=2x-1 y=-x-4 Graph the system. Then write its solution. Note that you can also answer "No solution" or "Infinitely many" solutions.
Answer:
The solution of the given system is: (-1,-3)
Step-by-step explanation:
Given equations are:
[tex]y = 2x-1\\y = -x-4[/tex]
Solving a system using graph means plotting the lines represented by the system of equations and then finding out where the lines intersect. If the lines intersect at only one point, that point is solution of the system.
We have used the online graphing calculator "Desmos" plot the lines.
Manually, the points can be obtained by substituting values of x in both equations
In the attached picture, the red line represents the first equation and the blue line represents the second. Both lines intersect at (-1,-3)
Hence,
The solution of the given system is: (-1,-3)

Point R is the midpoint of KL. If KR = 7x - 10 and RL = 3x + 34, find KL.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
R is the midpoint of KL ;
Thus R bisects KL , which means :
[tex]KR = RL[/tex]
So :
[tex]7x - 10 = 3x + 34[/tex]
Add sides 10
[tex]7x - 10 + 10 = 3x + 34 + 10 \\ [/tex]
[tex]7x = 3x + 44[/tex]
Subtract sides 3x
[tex] - 3x + 7x = - 3x + 3x + 44[/tex]
[tex]4x = 44[/tex]
Divide sides by 4
[tex] \frac{4x}{4} = \frac{44}{4} \\ [/tex]
[tex]x = 11[/tex]
_________________________________
[tex]KL = KR + RL[/tex]
[tex]KL = (7x - 10) + (3x + 34)[/tex]
[tex]KL = (7 \times 11 - 10) + (3 \times 11 + 34) \\ [/tex]
[tex]KL = (77 - 10) + (33 + 34)[/tex]
[tex]KL = (67) + (67)[/tex]
[tex]KL = 60 + 7 + 60 + 7[/tex]
[tex]KL = 60 + 60 + 7 + 7[/tex]
[tex]KL = 120 + 14[/tex]
[tex]KL = 134[/tex]

The measure of the angle is 44 times greater than its supplement.
What is the measure of the supplement?
Answer: The measure of it's supplement is 4°
Step-by-step explanation:
If an angle is 44 times is supplement, then we can represent it by the equation x = 44y where x is the angle and y is it's supplement.
Supplementary angles add up to 180 degrees, meaning that x + y = 180.
x = 44y
x + y = 180
Using both equations substitute the value for x in the first equation, into the second equation and solve for y.
44y + y = 180 Combine like terms on the left side
45y = 180 Divide both sides 45
y = 4
This means the measure of it's supplement is 4 degrees.
Now input 4 into one of the equations for y and solve for x to find the main angle.
x = 44(4)
x = 176
This also means that the angle itself is 176 degrees.
The measure of the supplementary angle is 4°.
It is given that the measure of the angle is 44 times greater than its supplement.
We have to find out the measure of the supplement.
What are supplementary angles ?
Two angles are said to be supplementary angles if the sum of two angles is 180°.
As per the question ;
The measure of the angle is 44 times greater than its supplement.
Let's assume the supplementary angle is x .
So,
The other angle will be 44 × x .
We know that sum of two angles if they are supplementary is 180°.
⇒ x + 44 x = 180 °
⇒ 45 x = 180°
⇒ x = 180 ÷ 45
⇒ x = 4°
And the other angle will be ;
= 44 × 4
= 176°
Thus , the measure of the supplementary angle is 4°.

Answer:
what r u finding the surface area or what?
Step-by-step explanation:
Answer:
1.) 36m 2.) 275cm
3.) 52m 4.)
Step-by-step explanation:
1.) First, I would multiply the triangles. The area for triangles is A=BxH/2.
So you would do 4mx3m=12m
12m/2= 6m but you're not done, you still have the rectangle. The area is A=LXW for the rectangle. So you would do 5m x 6m=30m. Finally, add. 30m + 6m= 36m
2.) Same thing as number one, but different numbers.
Triangle: 8cm x 10cm= 80cm
80cm/2= 40cm
Rectangle: 13cm x 15cm= 195cm
80cm + 195cm= 275cm
3.) Same as the last two except for it looks different and different numbers.
ignore the 5 to the left of the triangle.
3m x 8m= 24m
24m/2= 12m
5m x 9m= 40m
40m+12m= 52m
4.) I want you to try it first, then if not come back and ask. Hope it helps.

Determine the domain and range of the function shown in the graph.
Answer:
The domain and range of the function shown in the graph will be:
{x|x ≥ -4}; {y|y ≥ 2}
Thus, option 2 is true.
Step-by-step explanation:
We know that domain is the set of all possible values for which is the function is defined.First, let's check the domain. We see a closed circle at x = -4 and the graph is heading towards +ve infinity i.e. [-4, ∞).
A closed circle means the point is included in the domain.
Therefore, the domain is:
{x|x ≥ -4}
We know that the range is the set of values of the dependent variable for which a function is defined.Now, let's check the range. We see a closed circle at y = 2 and the y-values of the graph are heading towards +ve infinity. i.e. [2, ∞)
Therefore, the range is:
{y|y ≥ 2}
Hence, the domain and range of the function shown in the graph will be:
{x|x ≥ -4}; {y|y ≥ 2}
Thus, option 2 is true.
Find the measure of the missing angle.
77°
Answer: The missing angle is 13°
Step-by-step explanation:
Let ∠B
be the missing angle.
Let ∠A
be the angle that measures
77∘Let ∠C
the right angle that measures
90∘
The following is true of all triangles:
∠A+∠B+∠C=180∘
Express the above equation as
∠B
in terms of the other angles:
∠B=180∘−∠A−∠C
Substitute the values for ∠A and ∠C
∠B=180∘−77∘−90∘
∠B=13∘

Find the final sale price of a basketball that is $ 35 which is on sale for 50% and then gets an additional 10% off.
Answer:
$15.75
Step-by-step explanation:
$35 * 0.50 = 17.5
$35 - $17.50 = $17.50
$17.50 * 0.10 = $1.75
$17.50 - $1.75 =$15.75
Answer:
$15.75Step-by-step explanation:
To find the percent of a number, we need to express the percent as a decimal with the decimal point of the original percent moved two places to the left. We cannot add the two percents together. You are only paying 50% of the original price.
50% = 0.5
We will now move to decimal two places to the left.
0.005 x 35 = 17.50
Now, we find 90% (since we only care about the amount you are paying) of $17.50
0.009 x 17.50 = 15.75
