Answer:

Emily raised $37.5 and justin raised $57.5

Answer:

Emily raised $37.50

Justin raised $57.50

Step-by-step explanation:

<u>(Step 1)</u>

Say "x" equals the amount of money Emily made and "y" equals the amount of money Justin made. You can set up an equation with both of these variables because we know that they made a combined $95.

x = Emily's earnings

y = Justin's earnings

Emily + Justin = 95

x + y = 95

<u>(Step 2)</u>

The fact that there are two variables makes it difficult to find how much each person made individually. However, we can eliminate the "y" variable when we remember that Justin made $20 more than Emily. Now, we can substitute "x + 20" in for "y".

x + 20 = y

x + y = 95

x + (x + 20) = 95

<u>(Step 3)</u>  

Finally, we can solve for the "x" variable.

x + (x + 20) = 95

2x + 20 = 95                                <------ Combine like terms

2x = 75                                         <------ Subtract 20 from both sides

x = 37.5                                        <------- Divide both sides by 2

<u>(Step 4)</u>

Since we know the value of "x", we can plug it into one of the equations to find the value of "y".

x + 20 = y

37.5 + 20 = y

y = 57.5

PLEASE HELP! (see attached image) The equation of function h is h(x) = 1/2(x-2)^2. The table shows some of the values of functio
Mkey [24]

Answer:

A: -4

B: 4

C: m(x)<h(x) for every x, t.e m(x)>h(x) cann’t be treu for any value of x.

Step-by-step explanation:

I’m not sure what is fubction m. I will suppose it is linear function.

For example m(x)=x/2-2.

Part A: h(4)-m(16)=1/2(4-2)^2 - 16/2-2=2-6=-4

Part B: y-intersection on h(x), we find how is h(0). So h(0)=1/2(0-2)^2=2.

For m(x), m(0)=0/2-2=-2. So their y-intersections are fare away 4. (See photo)

Part C: First we chak if there any intersection between h and m.

1/2(x-2)^2=x/2-2, si we have

x^2-4x+4-x+4=0

X^2-5x+8=0,

D=5^2-4*8=25-32<0, so m and h don’t have intersection, and from graph we can see that for every value of x, m(x) will always be less than h(x).

Photo: blue is h(x), green is m(x)
