If 52 is 130% of a number, is the number greater then or less the 52? Explain
olga_2 [115]
X= a number

If 52 is 130% of a number, then we multiply the unknown number by 130%.

x * 130%= 52
convert % to decimal (130%÷100)

1.3x= 52
divide both sides by 1.3

x= 40


ANSWER: The unknown number is 40, so it is less than 52. We multiply the unknown number by 130% to equal 52.

Hope this helps! :)

Which of the following rules could represent the function shown in the table?
MariettaO [177]

Answer:

f(x) = 2x+1​

Step-by-step explanation:

Equation in slope intercept form y = mx + b where m = slope b = y-intercept

To find slope ,

m = (y2-y1)/(x2 - x1)

m = (3 - 1) / (1 - 0)

m = 32/1

m = 2

y-intercept b = 1

In this case y = 2x + 1 or f(x) = 2x+1​

Find the zeros of: <img src="https://tex.z-dn.net/?f=f%28x%29%3D-%5Cfrac%7B1%7D%7B1500%7D%20%28x%5E3%2B10x%5E2-275x-1500%29" id=
saul85 [17]

The function f(x) = -(1/1500)(x³ + 10x² - 275x - 1500) the zeros are at (-20, 0), (-15, 0) and (15, 0). Hence the factors of the function are x + 20, x + 15 and x - 15.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

From the graph of the function f(x) = -(1/1500)(x³ + 10x² - 275x - 1500) the zeros are at (-20, 0), (-15, 0) and (15, 0). Hence the factors of the function are x + 20, x + 15 and x - 15.
