Answer:
3.75
Step-by-step explanation:
half of 3 is 1.5 and half of 1.5 or a quarter of 3 is .75
Y=mx+b
m=slope
b=y intercept
just solve for y
5x+4y=16
minus 5x both sides
4y=-5x+16
divide both sides by 5
y=(-5/4)x+4
slope=-5/4
y intercept is y=4
The total value is seven hundredths. lmk if the is isn’t the answer you were looking for.
Answer: The consumer saves $45
Step-by-step explanation:
If you multiply 20 by 3 you get 60 then you multiply by .75 and you get 45
Its -1,3
<span>y=4<span>x2</span>+8x+7</span>
There is a formula for finding the vertex= <span>y=a<span>x2</span>+bx+c</span>
<span>h=−<span>b<span>2a</span></span></span> and <span>k=c−<span><span>b2</span><span>4a</span></span></span>
Solve for h with <span>a=4</span> and <span>b=8</span> and <span>c=7</span>
<span>h=−<span>b<span>2a</span></span>=<span><span>−8</span><span>2⋅4</span></span>=−1</span>
<span><span>
=</span>−<span>b<span>2a</span></span>=<span><span>−8</span><span>2⋅4</span></span>=−1</span>
Solve for k
<span>k=c−<span><span>b2</span><span>4a</span></span>=7−<span><span>82</span><span>4⋅4</span></span>=7−<span>6416</span>=7−4=3</span>
Our vertex is at <span>(−1,3)</span>
<span>y=4<span>x2</span>+8x+7</span> with vertex at <span>(−1,3)</span>
