I am guessing Jack is 51 and Lacey is 17.
If u want to make the shape larger, u will have to multiply it by the scale factor that is greater then 1.
if u want to make the shape smaller, then u will multiply by the scale factor that is between 0 and 1
if the scale factor is 1, then the shapes are congruent
<span>From the problem, you can get this equation:
Jane is 2 years older than Sally
J=z+2
David is 4 times older than Jane.
D=4J
</span>Write two equivalent expressions that represent David’s age in terms of Sally’s age, z, and explain how the two expressions relate to one another.<span>Sally is z years old.
From the 2 equation above, you can get:
</span>D=4J
D=4(z+2)
D=4z+8
D-8=4z
(D-8)/4=z
The two equivalent expression would be D=4z+8 and (D-8)/4=z
The expression that more usefull would be D=4z+8 if you want to determine David age.
C. (8,-2), (-2,5), (6,0) is a function, because all the numbers are different unlike A, B, and D those all have the same number either in there domain or range.
Step-by-step explanation:
x^2 -14x + 45 =0
look for two numbers that their :
sum= - 14 (-5 & -9)
products = 45 (-5 & -9)
so,
(x-5)(x-9)=0
thus,
x=5, x=9 (ANS)
