Graph the equation on the coordinate plane.



y = 4x

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)

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]

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∘

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.

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:

Step-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

Step-by-step explanation:

Slope Intercept Form is "y = mx + b"

What it means?

"m" - slope

"b" - y intercept (0,b)

So, we are given the slope, but not the y intercept..

For now, lets fill in the slope.

y = 1/4x +  b

We are given a coordinate pair (-2,-1)

Fill it into the equation and solve for b.

-1 = 0.25(-2) + b

-1 = -0.50 + b

- 0.50 = b

We now have the value of "B"

Fill in the rest of the equation:

y = 1/4x + -.50

^ I think that is correct, sorry if it's wrong.

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:

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:

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}

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.
