I’m sorry I’m answering this to ask a question
Yes! In △RST, VT=60 in. What is the length of TX¯¯¯¯¯? It is 40 in.
Answer:
right 2 , up 3.
Step-by-step explanation:
The -2 moves 2 to the right and the + 3 means 3 up.
Answer:

Step-by-step explanation:
To find the exact solution, find the equation for each line. And solve for x and y.
To do this, represent each equation in the slope-intercept form, y = mx + b. Where m is the slope, and b is the y-intercept.
✍️Equation 1 for the line that slopes upwards from left to your right:
Slope = 
b = the point at which the y-axis is intercepted by the line = 7
Substitute m = 2 and b = 7 in y = mx + b
Equation 1 would be:
✔️y = 2x + 7
✍️Equation 2 for the line that slopes downwards from left to your right:
Slope = 
b = the point at which the y-axis is intercepted by the line = 1
Substitute m = -3 and b = 1 in y = mx + b
✔️Equation 2 would be:
y = -3x + 1
✍️Solve for x and y:
✔️To solve for x, substitute y = -3x + 1 in equation 1.
y = 2x + 7
-3x + 1 = 2x + 7
Collect like terms
-3x - 2x = 7 - 1
-5x = 6
Divide both sides by -5

✔️To solve for y, substitute x = -1⅕ in equation 2.
y = -3x + 1





✅The exact solution would be: 
B. is the answer because they have 2 variables that you need to combine “combine like terms”
