Answer:
x = 2
Step-by-step explanation:
8x + 5 = 3x + 15
8x - 3x + 5 = 3x - 3x + 15
5x + 5 = 15
5x + 5 - 5 = 15 - 5
5x = 10
5x / 5 = 10 / 5
x = 2
Answer:
y = 2x - 3
Step-by-step explanation:
The y-intercept is -3 because that is where the line hits the y-axis.
The slope is 2 because from 1 point the the next, you go up 2 right 1.
First you'd change the 68 yards to 194 feet. then you would make the equation (3x-2)+(3x-2)+x+x=204 because the length is 2 feet less than 3 times the width (x). when you combine like terms it is 8x-4=204. then you'd move the -4 over to the 204 to make it 8x=208. x=26 feet. then you plug it back in time find the length is 76 feet.
The axis of symmetry is x=-2, but you were close!
