Answer:

B is the right answer.

Step-by-step explanation:

56 + 0.08x = 164

0.08x = 164 - 56

0.08x = 108

0.08x/0.08 = 108/0.08

x = 1,350

To confirm that:

56 + 0.08x

56 + 0.08(1,350)

56 + 108

= 164

164 is the answer.

Ok so if your phone bill was $164
And your starting fee for five lines is $56, you would start with $56

What I would do is take $164 - $56 to get $108, then proceed to divide that by 0.08 to get 1350, and that would be my x variable

And the equation would be $56 + 0.08x =$164

Meaning the Answer Would Be:
B. 56 + 0.08x = 164, x = 1350

Which graph represents the function y= 2x-4?sty すす0-3xits : :os : ;-32pr ftーVetーTT it tie。pttーT-it-T +--+-

Sergio039 [100]

Solutions

You have been given the y-intercept of -4. The meaning of this is that the given line will go through the point (0, -4). Plug in 1 for x and find y.

$
y = 2x - 4

y = 2 * 1 - 4

y = 2 - 4

y = -2$


In graph C,= x = 1, y = -2

Graph C is the correct answer.

Graph f(x)=2^x+1 and g(x)=−x+4 on the same coordinate plane.

12345 [234]

Given f(x)= 2^x +1

g(x)= -x +4

We have to find the value of x which satisfy the condetion : f(x)= g(x)

Solution : let us place expression given for f(x) and g(x) equal to each other

This gives us : 2^x + 1 = -x+ 4

Let us bring all x terms on left side only

we add x on both sides this makes : 2^x +1 +x = -x+ 4 +x

on the right side -x and +x becomes a "0"

we get : 2^x + 1 + x = 4

* let us nopw bring all the numeric terms on left side only

subtract 1 from both sides : 2^x + 1 + x - 1 = 4- 1

on the left side +1 and -1 becomes a "0"

on the rigth side 4-1 becomes a "3"

equation look like : 2^x + x = 3

We can see the right side is an odd number

on the left side there is sum of two terms one of them is 2^x which is an even number always .

we know that sum of an even number with an even number result out an even number

but we want a result as an odd number (3)

this suggest that x should be an odd number .

Also the sum of 2^x and x is 3 so 2^x should be smaller than 3

the smallest value ( x being an integer )

2^x can have is : 2^1= 2 which is for x=1

let us check plugging x= 1 . 2^1 + 1 = 3 which is TRUE

Hence answer is x= 1
