Answer:

y=(x+8)^{2}

Step-by-step explanation:

we have that

The ordered pairs (1, 81), (2, 100), (3, 121), (4, 144), and (5, 169) represent a function

The rule that that represent this function is equal to

y=(x+8)^{2}

Verify

For x=1 -----> Find the value of y in the equation

y=(1+8)^{2}=81 -----> is correct

For x=2 -----> Find the value of y in the equation

y=(2+8)^{2}=100 -----> is correct

For x=3 -----> Find the value of y in the equation

y=(3+8)^{2}=121 -----> is correct

For x=4 -----> Find the value of y in the equation

y=(4+8)^{2}=144 -----> is correct

For x=5 -----> Find the value of y in the equation

y=(5+8)^{2}=169 -----> is correct

To determine what function is the correct answer we use the choices listed above to substitute x and obtain the value of y and see if it corresponds to the given y value. We do as follows:

<span>y = x^8
y = (1)^8
y = 1 ----> NOT THE ANSWER

y = 8^x
y = 8^(1)
y = 8</span>---> NOT THE ANSWER<span>

y = (x + 8)^2
y = (1+8)^2
y = 81

y = 8x
y = 8(1)
y = 8 </span>---> NOT THE ANSWER

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
larisa86 [58]

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.
