What is the equation of the line whose y-intercept is 3 and slope is 1?

Answer: " y = x + 3 " .

___________________________

Explanation:

___________________________

Consider the equation of a line, in "slope-intercept form" ;

which is: " y = mx + b" ;

in which: "m" refers to the "slope of the line", which is the coefficient of "x".

"b" refers to the "y-intercept" of the line", which is given as "3" ; which is the coordinate of "x" of the point at which "y = 0".

_________________________________________________

So, we can plug in our given values for "m" and "b" into the equation, and write the equation:

_________________________________________________

y = 1x + 3 .

_________________________________________________

By convention, we can write the "1x" as simply "x" ; since there is an "implied coefficient" of "1" ; and an ["implied"] slope, "m", of "1" ; since any value, multiplied by "1", results in that exact same number. So we can write the equation as:

________________________________________

" y = x + 3 " .

Find the value of the expression 74.9+5.23-81.4-16

Answer:

To find the value of this expression you need to add and subtract from left to right

74.9+5.23-81.4-16 (add the first two, first)

80.13-81.4-16 (74.9+5.23=80.13) (next subtract the next two)

-1.27-16 (80.13-81.4=-1.27) (Last subtract the last two)

-17.27 (-1.27-16=-17.27)

-17.27

Hope this helps ;)

When multiplying 2x-8/x^2-4 times x^2+6x+8/x-4, what are the term(s) that can be cancelled

Answer:

(x-4) and (x+2) are terms that can be cancelled

Step-by-step explanation:

we are given

Firstly, we will factor terms

and then we can cancel common terms

now, we can replace it

now, we can see that

(x-4) and (x+2) are common

so, they will get cancelled

so, we can see that

(x-4) and (x+2) are terms that can be cancelled

jamerra received a $3,00 car loan. she plans on paying off the loan in 2 years. at the end of 2 years, jamerra will have paid $450 in interest. what is the simple intrest rate on the car loan?

The rate of interest is 75 % per year

Solution:

Given that, Jamerra received a $3,00 car loan

she plans on paying off the loan in 2 years

Jamerra will have paid $450 in interest

Therefore, we get

Principal = $ 300

Number of years = 2

Simple Interest = $ 450

Rate of interest = ?

The simple interest is given by formula:

Where,

"p" is the principal and "n" is the number of years and "r" is the rate of Interest

Substituting the given values we get,

Thus rate of interest is 75 % per year

Fin the original price of a pair of shoes if the sale price is $60 after a 60% discount the original price is

Answer:

To add percentages, you have to make the percentage into a decimal with "1" as the whole number if it's lower than 100%.

So, $60 x 1.60 =

$96.00

The original price of the pair of shoes were: $96.00
