A company makes and sells customized yard signs. If you order 5 signs, they charge $72 which includes shipping. If you purchase
klemol [59]

The slope is of $13, which means that each new sign costs $13.

-----------------

A linear function has the following format:

y = mx + b

In which

  • m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
  • b is the y-intercept.

-----------------

  • In the linear function in this problem, we have two points (x,y): (5,72) and (15,202).
  • The slope is given by the <u>change in y divided by the change in x</u>, thus:

m = \frac{202 - 72}{15 - 5} = 13

  • The slope is of $13, which means that each new sign costs $13.

Step-by-step explanation:

well f of 82 = 2 plus _ plus _ plus _ and f of 86 is 2+_+_+_ subtract them

 (A)  3            (B)   4           (C)   47            (D)   59             (E)   83

these are some possible answers so the answer is b, 4

Suppose f(x) = x^2 and
SpyIntel [72]

Given:

The two functions are:

f(x)=x^2

g(x)=\left(\dfrac{1}{3}x\right)^2

To find:

The statement that best compares the graph of g(x) with the graph of f(x).

Solution:

The horizontal stretch is defined as:

g(x)=f(kx)            ...(i)

If 0, the function f(x) is horizontally stretched by factor \dfrac{1}{k}.

If k>1, the function f(x) is horizontally compressed by factor \dfrac{1}{k}.

We have,

f(x)=x^2

g(x)=\left(\dfrac{1}{3}x\right)^2

Using these functions, we get

g(x)=f\left(\dfrac{1}{3}x\right)         ...(ii)

On comparing (i) and (ii), we get

k=\dfrac{1}{3}

Since 0, the function f(x) is horizontally stretched by factor \dfrac{1}{\frac{1}{3}}=3.

Hence, the correct option is D.

together = add

add the fractions

3 7/10 + 5 9/10

add the whole numbers first

3+5=8

add the fractions

7/10+9/10= 16/10

8 16/10

reduce 16/10 divide by 2

16/2= 8

10/2= 5

8 8/5

whole number changes to 9

8-5=3

denominator stays the same
