We have learned that, in in an algebraic expression<span>, letters can stand for numbers. When we substitute a specific </span>value<span> for each variable, and then perform the operations, it's </span>called<span> evaluating the </span>expression<span>. Let's evaluate the </span>expression<span> 3y + 2y when 5 = y.</span>
Answer:
B. g(x)= |x| + 5
Step-by-step explanation:
-5 represents a vertical shift down, so that narrows it down to either A or B. A shows a shift across the horizontal (X) axis, so it must be B.
Answer:
A =315 cm^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) *h
where b1 and b2 are the lengths of the bases and h is the height
A = 1/2 ( 13+29) *15
A = 1/2 (42)* 15
A =315 cm^2
