Answer:
∠3 = 55° {being vertically opposite angles}
∠7 = ∠3 = 55° {being corresponding angles}
It is an isosceles triangle
Answer:
V = 67 1/2 cm^3
Step-by-step explanation:
The volume is given by
V = l*w*h
V = 4 1/2 * 6 * 2 1/2
Changing to improper fractions
V = 9/2 *6*5/2
V =270/4
V = 135/2
Changing to a mixed number
V = 67 1/2 cm^3
we know that
The formula to calculate the slope m between two points is equal to

Step 
<u>Find the slope of the function f(x)</u>
Let

substitute the values in the formula above


<u>the slope of the function f(x) is
</u>
Step 
<u>Find the slope of the function g(x)</u>
Let

substitute the values in the formula above



the slope of the function g(x) is 
therefore
slope f(x) > slope g(x)
or
slope g(x) < slope f(x)
<u>the answer is the option </u>
B.The slope of g(x) is less than the slope of f(x).
Use symbolab it helped me a lot and good luck!
