Answer:

Step-by-step explanation:

Find the two similar sides which are already measured.

6 and 9 are those numbers.

Use similarity proportional ratio:

6/9 = z/15

Cross multiply:

9z = 15 × 6

9z = 90

z = 90 ÷ 9

z = 10

Describe how the graph of the equation relates to the graph of y = x2. f(x) = -x + 5)2

Kobotan [32]

Answer:

Step-by-step explanation:

It's y = x^2, not y = x2. The graph of y = x^2 is a parabola with vertex (0, 0) and which opens up.

The graph of y = (x + 5)^2 has the same shape as that of y = x^2, but has been translated 5 units to the left.

It will cost Amber an estimated $3,723 a year in tuition to attend her preferred college. She has been putting $350 a month in a

kenny6666 [7]

Answer:

Yes; she will have $4008 for other expenses.

Step-by-step explanation:

First you find out how much she saved by multiplying 350 by 36 as she saved for 3 years which is 36 months.

$350 \times 36 = 12600$

After that you need to work out the amount she needs in total for her tuition by multiplying 4 by 3723 which is the amount needed per year.

$3723 \times 4 = 14892$

If her parents add to her account half the amount she saved that means that they give her an additional 6300 as that's half of 12600.

This means she has 18900 and if you take away 14892 you will be left with 4008 for expenses.

the peach festival charges $5 for admission then$1.25 per pound of peaches picked. If Savanna went to the festival and picked 2.

Mumz [18]

Answer:

I'm glad you asked!

Step-by-step explanation:

So let's do it step by step.

Already she has to pay $ $5$ for going in.

She has $2$ whole pounds.

$1.25$ x $2=2.5$ or $2 \frac{1}{2}$

Add $ $5$ and $ $2.5$ .

$5+2.5 = 7.5$

Now let's do $1.25 divided by 10.

$$$ $ $1.25$ divided by $ $10$ $=0.125$

Now let's do $0.125$ times $4$

$0.125$ x $4 = 0.5$

Now let's add 7.5 to 0.5

$7.5+0.5=8$
