EB * AE = DE *EF
x+3 *3 = 6*x-2
simplify:
3x+9 = 6x-12
subtract 3x from each side
9 = 3x -12
add 12 to each side
21 = 3x
divide both sides by 3
x = 21/3
x = 7
replace x with 7 to find EB
EB = 7+3 = 10 cm
Distribute the -3 through the expression -3 x b=-3b+21
21 from -3*-7
Answer:
(C) Annie did not make a mistake
Step-by-step explanation:
To isolate the variable k in the equation , we'd have to subtract 7.5 from both sides so we just had k on one side.
This is exactly what Annie did, and therefore, her answer is correct.
Hope this helped!

Answer:
d. y = -2×
Step-by-step explanation:
First to solve find the slope using the formula, . The slope equals 20/-10 or -2. Then plug the slope and point, (-5,10), into slope-point form. y-10=-2(x+5), then solve for y. This gives you y=-2x+0 or y=-2x.
