Answer:
4v^2-25
Step-by-step explanation:
(2v+5)(2v-5)
Using (a-b)(a+b)=a^2-b^2, simplify the product
(2v)^2-5^2
To raise a <u>product to a power</u>, raise each factor to that power.
4v^2-5^2
Evaluate the <u>power.</u>
4v^2-25
Answer:
y = 1/2x - 7
Step-by-step explanation:
y = mx + b
m (slope) = 1/2
x = 4
y = -5
<em>substitute</em>
-5 = 1/2 * 4 + b
-5 = 2 + b
-5 -2 = b
-7 = b
y = mx + b
y = 1/2x -7
