Answer:
Step-by-step explanation:
We need to remember 2 rules when doing these:
1.
2.
Using these 2 rules, we can simplify the product (steps shown below):
Rearranging, we see that it is the third choice.
A graph shows the solution is (x, y) =
(4, 3).
By utilizing 3-dimensional geometry instead of 2-dimensional geometry.
Hope it helps!
Answer:
a=25,b=-23
Step-by-step explanation:
f(x)=6x-5
a. f(5)=6(5)-5
f(5)=30-5
f(5)=25
b. f(-3)=6(-3)-5
f(-3)= -18-5
f(-3)=-(18+5)
f(-3)=-(23)
f(-3)=-23
