There's more than 4 correct answers but...
Answer: C
Step-by-step explanation:
5x+3y=13
+(-5x-12y=23)
---------------------
-9y=36
y=-4
To find x plug in y into any equation.
5x+3(-4)=13
5x=25
x=5
Answer:
y= 2x-4
Could you give me brainliest
Step-by-step explanation:
Slope-intercept form: y= mx+b
-2x+y= -4
+2x +2x
y= 2x-4
y = (2x-4)/3
to find the inverse change x and y then solve for y
x = (2y-4)/3
mutiply by 3 on each side
3x = 2y-4
add 4 to each side
3x+4 =2y
divide by 2
(3x+4)/2=y
h^-1 (x) = (3x+4)/2
