Answer:
True
Step-by-step explanation:
Any point on the x- axis has a y- coordinate of zero, hence
(2, 0) lies on the x- axis
the answers is f(4)=5 ^ ^
First you need to convert them to the same unit. 1 cm is 10 mm, so the scale is 5:10. 5*2 is 10, so the scale factor is 2.
Remember
if |a|=b then assume a=b and a=-b
divide boths ides by -3
|2x+6|=4
assume
2x+6=4 and 2x+6=-4
minus 6 both sides
2x=-2 and 2x=-10
divide by 2
x=-1 and x=-5
2nd option
X = 7
8(7) = 5(7) + 21
56 = 35 + 21
56 = 56
