Answer:

She needs a 96

Her average score now is: 91

Step-by-step explanation:

She needs a total of 460 points.  She has already taken 4 of the 5 tests, and earned

85 + 93 + 89 + 97 = 364 points, so she needs

460 - 364 = 96 points

Her average score now is the sum of her scores, divided by the number of tests she has taken, which is...

364/4 = 91

You are gonna use the distributive property.

4(2.5g - 4) + 3(1.2g - 2)

So you are going to multiply 4 with everything inside the first set of parenthesis and your gonna multiply 3 with everything insides the second set of parenthesis.

4 x 2.5g - 4 x 4 + 3 x 1.2g - 3 x 2

10g - 16 + 3.6g - 6

You wanna combine like terms:

10 - 3.6g + 16 - 6

6.4g + 10

You answer is 6.4g + 10.

Hope this Helps!!

How do I write an equation for each parabolas?
fredd [130]

Step-by-step explanation:

  1. In the first parabola it opens on the left and the equation of parabola can be expressed as,

              in vertical component <u>(y)² = (-) a (x-h)² + k</u>

cause  the parabola is horizontal and it opens on the left.

          2. In the second parabola the vertex opens on the right and hence the      equation cane be given as,

    in vertical component <u>(y)² = a (x-h)² + k</u>

cause the parabola is horizontal and opens on the right.

       3. the third equation is given as,

        in horizontal component<u> (x²) =</u> <u> (-) a (x-h)² + k</u>

since the parabola is vertical and opens down.

        4. the fourth equation is given as,

        in the horizontal component  <u>(x)² = a (x-h)² + k</u>

since the parabola is vertical and opens up.
