Answer:
D
Step-by-step explanation:
Take x = 1.
Now substitute in the function.
f(1) = 3 + √1
f(1) = 3 + 1
f(1) = 4
Now, we know the line of the function passes through 2 points : (0, 3) and (1, 4). Graph D shows these features.
y = -3x-1
all u had to do was plug it into y = mx+b
x=-27, y=-15
In the attached file
6 inches
A=b1+b2/2*h
Fill in the equation with what we know
21=8+x/2*3
Isolate x
Quick steps: 21/3=7*2=14-8=6
x=6
