Y=0.50x-55
So 0=0.50x-55
Add 55 from both sides
55=0.50x
Divide 0.50 on both sides
55 /0.50 = 110
I could be wrong so yup

For both of these, we will divide the wanted outcome by the number of possible outcomes. We will end up with a decimal. A decimal multiplied by 100 becomes a percent.

[a] 50%

$\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed}}{\text{Period 2's class}} =\frac{12}{24} =0.5,\:0.5*100=50\%$

[b] 52%

$\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed from Period 3}}{\text{fails from both classes}} =\frac{13}{25} =0.52,$

$\displaystyle 0.52*100=52\%$

Answer:

See below

Step-by-step explanation:

<u>Zeroes</u>

$f(x)=2(x-1)(x+3)$

$0=2(x-1)(x+3)$

$0=(x-1)(x+3)$

$x=1$ and $x=-3$

$(1,0)$ and $(-3,0)$

<u>Axis of Symmetry</u>

$f(x)=2(x-1)(x+3)$

$y=2(x-1)(x+3)$

$y=2(x^2+2x-3)$

$y+2(4)=2(x^2+2x-3+4)$

$y+8=2(x^2+2x+1)$

$y+8=2(x+1)^2$

$y=2(x+1)^2-8$

$y=a(x-h)^2+k$

$x=h$

$x=-1$

<u>Vertex</u>

$y=a(x-h)^2+k$

$y=2(x+1)^2-8$

$(h,k)\rightarrow(-1,-8)$

<u>Y-intercept</u>

$f(x)=2(x-1)(x+3)$

$f(0)=2(0-1)(0+3)$

$f(0)=2(-1)(3)$

$f(0)=-6$

$y=-6$

$(0,-6)$

Please review the attached graph for a visual of these key features.

Solve 16x + 8 > 12x+ 20.

MrRa [10]

Answer:

x > 3

Step-by-step explanation:

16x + 8 > 12x + 20 <== subtract 12x from both sides

- 12x - 12x

4x + 8 > 20 <== subtract 8 from both sides

- 8 - 8

4x > 12 <== divide both sides by 4

/4 /4

x > 3

This means that x is any value that is greater (bigger) than 3.

Hope this helps!
