1 answer:

3 0

X = 6y - 3
x + y = 53

6y - 3 + y = 53
7y - 3 = 53
7y = 53 + 3
7y = 56
y = 56/7
y = 8

x = 6y - 3
x = 6(8) - 3
x = 48 - 3
x = 45

ur numbers are : 8 and 45

See below

Step-by-step explanation:

Okay so...I might be interpreting the question wrong-if I am please comment! I'll fix it to the best of my ability.

A) Plug in -5 to all x values

f(-5)=10(-5)-3

==50-3

f(-5)= -53

B) f(0)=10(0)-3

f(0)= -3

C) f(7)=10(7)-3

=70-3

f(7)=67

D) f(t^2+2)=10(t^2+2)-3

=10t^2+20-3

f(t^2+2)=10t^2+17

E) f(12-x)=10(12-x)-3

=120-10x-3

f(12-x)=117-10x

F) f(x+h)=10(x+h)-3

=10x+10h-3
