If x=3m-4 and y=6-m, which of the following expresses y in terms of x

Answers

Answer 1

Answer:

What you want to do is solve for m in whichever equation it's easier to so in, then substitute that in to the other equation. For instance:

X=3m-4

Y=6-m

Solve the 2nd equation to get m=6-y

Plug that into the first equation to get x=3(6-y)-4

X=18-3y-4

X-14=-3y

14-x=3y

Y=(14-x)/3

Answers

Answer:

x=-7

Step-by-step explanation:

-2(x−3)+4x=−(−x+1)

Step 1: Simplify both sides of the equation.

−2(x−3)+4x=−(−x+1)

−2)(x)+(−2)(−3)+4x=x+−1(Distribute)

−2x+6+4x=x+−1

(−2x+4x)+(6)=x−1(Combine Like Terms)

2x+6=x−1

2x+6=x−1

Step 2: Subtract x from both sides.

2x+6−x=x−1−x

x+6=−1

Step 3: Subtract 6 from both sides.

x+6−6=−1−6

x=-7

Answers

Answer: 4 ones+5 tenths+15 hundredths=4.65

Explanation: We can use multiplication to check our work.

)Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:


Year Lawn Care Fee
2000 $750
2010 $1350


A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.

Answers

Answer:

Rate of change = (1350 - 750)/(2010 - 2000) = 600/10 = $60

Initial value = $750

Equation is y = 60x + 750; where y is the amount charged to customer and x is the number of years from 2000.

DONT SAY I DONT KNOW

Answers

Answer and Step-by-step explanation:

[tex]\frac{5}{x-9}[/tex]

The domain is all real numbers except 9 (positive)

This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.

if I have a 53 in class what grade do I need to get in a test to get a 90

Answers

Answer:

you would have to make 100s on at least 5 tests or assignments

Step-by-step explanation:

Answer:

It depends.

Step-by-step explanation:

Basically, your grade is a result of the average score on all of your assignments and even attendance. Average is all scores added together, divided by the number of scores. Also, depending on the teacher, some scores weigh more, meaning a test counts for more than a worksheet does.

Also, even if you get a 100 on your test, you'll unlikely get a 90. :(
