You can use elimination
7x - 3y = 4
-10x + 3y = 2
Add both equations
-3x = 6, x = -2
Plug in -2 for x in one equation
7(-2) - 3y = 4
-14 - 3y = 4
-3y = 18, y = -6
Solution: x = -2, y = -6
Answer:
Yes
Step-by-step explanation:
In the equation, -1.3 is the y-intercept. The y-intercept always has a x value of 0. On the point (0,-1.3), it matches the y-intercept and is therefore part of the function/equation.

Answer: $18.75
Step-by-step explanation:
1 - 3/8 = 5/8
12 x 5/8 = 7.5
7.5 x 2.5 = 18.75
The answer is: 12x5+x3+9x2+4
This is the correct answer because all of the exponents are in the correct calculation and the numbers as well.
I hoped this helped! :)
