If f ( x ) f ( x ) is a linear function, f ( − 5 ) = 0 f ( - 5 ) = 0 , and f ( 2 ) = 4 f ( 2 ) = 4 , find an equation for f ( x

Effectus [21]

Answer:

f(x) = 4/7x + 20/7

Step-by-step explanation:

If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:

<u>(first y-coordinate - the second y coordinate)</u>

(first x-coordinate - second x coordinate)

= <u>(0 - 4)</u>

(-5 - 2)

= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.

Thus, the answer is f(x) = 4/7x + 20/7

Answer:

Step-by-step explanation:

You multiply the two numbers together:

Top left, purple tile: 3x(x) = 3x^2

Top right, pink tile: 4(x) = 4x

Bottom left, yellow tile: 3x(2) = 6x

Bottom right, blue tile: 4(2) = 8

Basically u multiply the variable above it and the variable at its left

A school gymnasium is being remodeled. The basketball court will be similar to an NCAA basketball court, which has a length of 9

valkas [14]

Answer:

Perimeter of NCAA court=288 feet

Perimeter of new court=259.2 feet

Step-by-step explanation:

We are given that

Length of NCAA court, l=94 feet

Width of NCAA court, b=50 feet

Width of new court, b'=45 feet

We have to find the perimeter of an NCAA court and new court in the school.

Perimeter of NCAA court= $2(l+b)$

Perimeter of NCAA court= $2(94+50)$ feet

Perimeter of NCAA court=288 feet

When two rectangles are similar then the ration of their corresponding sides are equal.

Using the property

$\frac{Perimeter\;of\;NCAA\;court}{Perimeter\;of\;new\;court}=\frac{Width\;of\;NCAA\;court}{Width\;of\;new\;court}$

$\frac{288}{Perimeter\;of\;new\;court}=\frac{50}{45}$

Perimeter of new court= $\frac{288\times 45}{50}$ feet

Perimeter of new court=259.2 feet

Use what you know about the properties to rewite each number sentence. Use mental math to find the sum. 0.6 + (0.4 + 0.9) = n an

dusya [7]

First Equation:

0.6 +(0.4+0.9) =n

Step 1: do parentheses first:

0.4+0.9 = 1.3

Step 2: Add 0.6 + 1.3

0.6 + 1.3 = 1.9

n= 1.9

Second Equation:

(1.57 + 0.75) + 0.25 + n

Step 1: do parentheses first:

1.57 + 0.75 = 2.50

Step 2: Add 2.50 + 0.25 = 2.75

Step 3: Add 2.75 and n = 2.75+n

Final Answer:

1.9 +2.75+n = 4.65 +n

Hope this helps!!
