what is the awnser to -6 > -2 + n

Answers

Answer:

Step-by-step explanation:

n<−4

Let's solve your inequality step-by-step.

−6>−2+n

Step 1: Simplify both sides of the inequality.

−6>n−2

Step 2: Flip the equation.

n−2<−6

Step 3: Add 2 to both sides.

n−2+2<−6+2

n<−4

Okay so I’m doing graph questions, so what’s “g(x) = x + 1” and what are the blanks?

Answers

Answer:

g(0) = 1, g(1) = 2, g(2) = 3, g(3) = 4, g(4) = 5

Step-by-step explanation:

g(x) is a function meant to modify the variable x.

Basically you take the x value in the table that you want to modify and you plug it into the g(x) function.

If you want 0, you do g(0) = (0) + 1 = 1.

Or if you want 3, you do g(3) = (3) + 1 = 4

solve for m. show you work. 6 (m - 8) = 30​

Answers

Answer:

m=13

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6(m−8)=30

(6)(m)+(6)(−8)=30(Distribute)

6m+−48=30

6m−48=30

Step 2: Add 48 to both sides.

6m−48+48=30+48

6m=78

Step 3: Divide both sides by 6.

6m/6=78/6

m=13

Need help with the x and y intercepts of a table.
Picture shown

Answers

Answer:

Correct Choice: d.

Step-by-step explanation:

Intercepts of a Function

Given a function y = f(x), the intercepts of f are defined as:

The x-intercepts are those points where the function has a value of 0

The y-intercepts are those points where the x has a value of 0

The table shows a set of ordered pairs (x,y). All those pairs where x=0 are the y-intercepts:

The y-intercepts are: (0,16)

All those pairs where y=0 are the x-intercepts:

The x-intercepts are: (3,0) (-5,0)

Correct Choice: d.

Given f(x) =
-3/4 x + 2, find f(16).

Answers

f(16) = -3/4(16) + 2

Robin has $450 to spend on home repairs. The repairman charges $65 for the initial visit and $37.50 per hour or part of an hour. How many hours of work can Robin afford?

Answers

Answer:

6 hours

Step-by-step explanation:

First set up the equation. Seeing the word "per", we know that this will be the variable. The repairman charges an initial fee of 37.50, so we add that fee to the total cost of every hour. To find how much Robin can spend, you set it equal to 450

65x + 37.50 = 450

Now subtract 37.50 from both sides because neither number has a variable, so you can subtract them to simplify the equation

65x = 412.5

To isolate x and find what it's equal to, divide both sides by 65 to get rid of the coefficient.

x = 6.34.

However the answer should be 6 because robin cannot afford a full or part of a 7th hour

Find an equation for the nth term of the arithmetic sequence.

a19 = -58, a21 = -164

a. an = 896 - 53(n - 2)
b. an = 896 - 53(n - 1)
c. an = 896 + 53(n + 1)
d. an = 896 - 53(n + 1)

Answers

Answer:

The common difference would be calculated as:

(a21-a19)/2

(-164--(-58 ))/2 (Replacing the values )

(-164 +58)/2 (Changing signs)

(-106)/2(Subtracting)

-53

Then we are going to replace the common difference(d) in the sequence formal with the 21st term . It is done for finding the first term of the sequence.

a21=a0+d*(n-1)

-164=a0+-53*(21-1) (Replacing the values)

-164=a1-53(20) (Subtracting)

-164=a1-1060 (Multiplying )

-164+1060=a1 (Adding 1060 on both sides of the equation)

896=a1

The answer would be : an= 896-53*(n-1), which is the option B.
