Answer:

y= -2x+3

Step-by-step explanation:

Point slope form= y=mx+b

The m is the slope.

So, we have an incomplete equation right now: y= -2x+b

We want to find b. We can do that by plugging in values for the x and y coordinates. Fortunately, we do have a set of coordinates, (1, 1)!

We plug them in:

1= -2(1)+b

1= -2+b

b=3

So, since we have the slope and the b, also called the y-intercept, we can form an equation!

y= -2x+3

On Sunday a library checked out 52books .if 24 of the books were fiction what is the ratio of non fiction books to fiction books
lana66690 [7]

Answer:

Ratio of Non Fiction : Fiction books = 7 : 6

Step-by-step explanation:

Total number of books checked out =  52

Number of fiction books checked out = 24

So, number of non fiction books =  Total books -  number of fiction books

Or, number of non fiction = 52 - 24   =  28  books

Now, ratio of Non Fiction : Fiction books = 28 : 24

Solving the ratio term in its lowest form, we get

The Ratio of Non Fiction : Fiction books = 7  : 6

Point A is located at -0.75 and point B is located at 1/4
Murrr4er [49]

Answer:

-0.25

Step-by-step explanation:

need to find the halfway point (average) between -0.75 and 0.25 (same as 1/4)

To get average, add them together: (-0.75) + (0.25) = -0.5, divide by two since there are two numbers, to get average -0.25

Astrid is looking for a job at a call center. Call center A offers her 15 dollars per hour and call center B offers her 25 cents
KIM [24]

Call center A and B offers equal wages.

<h3>what is Equation?</h3>

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

The formula for wages = P/t

First, P= 15 dollars

           = 1500 cents

time= 1 hour= 60 minutes

then, the unit rate is

=1500/60

= 25 cents/ min

Second, P= 25 cents

       

time= 1 minutes

then, the unit rate is

=25/1

= 25 cents/ min

Hence, Call center A and B offers equal wages.
