The weekly salary Y of an individual is proportional to the number of hours X worked. A person who works 40 hours is paid 900$. Write an equation that represents the situation. Then determine how many hours the individual worked if the amount paid is 630$ An equation that represents the situation is y =

An individual has worked hours if the amount paid is 630$

PL HELP ME OUT. the () is where the answer goes

y = 22.5x

worked 28 hours

Step-by-step explanation:

First find out what they make in 1 hour (rather than 40)

you can do this by 900 / 40 which gives you 22.5

this means for every hour worked, they get $22.50

so you can make the equation of y = 22.5x

try finding the hours worked by division

630/ 22.5 = 28

plug 28 into your equation to check

y = 22.5 ( 28 )

y = $630

hope this helps

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
