if the edwards drive 225 miles, which company would be a better deal? if the edwards only have to spend, which company would be
VikaD [51]

i can give you the exact answer to your question, but what are the equations for the companies and  how much do the edwards have to spend? if not, here's how to do it:

y= m(225)+b for each company. i used slope-intercept form assuming that's what form the equations are written in. it's basically saying x=225 in part a (look for the lowest y) and in part b y≥m(225)+b (look for which company's equation makes the statement true)

(ps i'm checking every few minutes if you want to comment and get the exact answer)

Prove that if m + n and n + p are even integers, where m, n, and p are integers, then m + p is even. what kind of proof did you
scoray [572]
Prove that if m + n and n + p are even integers, where m, n, and p are integers, then m + p is even.
m=2k-n, p=2l-n

Let m+n and n+p be even integers, thus m+n=2k and n+p=2l by definition of even
m+p= 2k-n + 2l-n substitution
= 2k+2l-2n
=2 (k+l-n)
=2x, where x=k+l-n ∈Z (integers)
Hence, m+p is even by direct proof.

April worked 1 1/2 times as long on her math project as Carl. For how many hours did April work on her math project?
natima [27]

Answer: 7 7/8 hours long

Step-by-step explanation:

April worked 1 1/2 times as long as Carl did. 1 1/2 can be rewritten as 3/2. Number of Hours April worked on math project 3/2 times the Number of Hours Carl worked on Math project. Which Carl worked 5 1/4 hours long, which can be rewritten as 21/4

What is the equation of the line that passes through (-2, 2) and (1, -4)?
poizon [28]

Answer:

y = - 2x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁  = (- 2, 2) and (x₂, y₂ ) = (1, - 4)

m = \frac{-4-2}{1+2} = \frac{-6}{3} = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, 2), then

2 = 4 + c ⇒ c = 2 - 4 = - 2

y = - 2x - 2 ← equation of line

How can we use the graph of a logarithmic function to​ verify the domain of a function?PLEASE HELP
guajiro [1.7K]
The function y = log 2 x has the domain of set of positive real numbers and the range of set of real numbers. Remember that since the logarithmic function is the inverse of the exponential function, the domain of logarithmic function is the range of exponential function, and vice versa.
