1. 3x - 3y = 9

to find the x or y intercept, multiply the other variable that you are not tryng to find by 0

3x - 3(0) = 9 3(0) - 3y = 9

3x = 9 -3y = 9

3x/3 = 9/3 -3y/-3 = 9/-3

x = 3 y = -3

2. I did the same thing for the rest

x = 6 y = -2

3. x = 2.5 y = -5

4. x = -4 y = -2/3

What is the value of X

alexdok [17]

Answer:

$x=12$

Step-by-step explanation:

We have been given a graph of similar triangles. We are asked to find the value of x.

Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.

$\frac{3}{x+3}=\frac{4}{16+4}$

$\frac{3}{x+3}=\frac{4}{20}$

Upon cross multiplying our equation we will get,

$4*(x+3)=3(20)$

Upon distributing 4 we will get,

$4x+12=60$

Let us subtract 12 from both sides of our equation.

$4x+12-12=60-12$

$4x=48$

Upon dividing both sides of our equation by 4 we will get,

$\frac{4x}{4}=\frac{48}{4}$

$x=12$

Therefore, the value of x will be 12.

luda_lava [24]

Answer:

Step-by-step explanation:

Evan has 43 and Brayden has 42. Reid has 76 and Bryce has 23. Which pair of boys has more? How much more do they have?

Reid and Rryce have more. If you add 43 and 42 you get 85 and when you add 76 and 23 you get 99. So now subtract 99 and 23 which is 76.

Find the distance between (-6,4) and (-2,1)

zhannawk [14.2K]

Answer:

$d=2.65$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the formula to find distance <em>d</em>:

$d=\sqrt{(-2-(-6))^2-(1-4)^2}$

$d=\sqrt{(-2+6))^2-(-3)^2}$

$d=\sqrt{(4)^2-9}$

$d=\sqrt{16-9}$

$d=\sqrt{7}$

$d=2.65$
