Answer:
Variables: you are correct
Coefficients: -2
Constant: 3/7
Step-by-step explanation:
Variables are letters used in math so you were correct.
Coefficients are numbers with a variable. So to find the coefficient you would look for a number "connected" to a variable. This would be -2 because it is being subtracted from the first term.
The constant is 3/7 because you could put it on a number line.
Find a solution to the equation without writing anything down.

2^2 = 2 • 2 = 4
4 + 5 + 50 ÷ 2(5)
4 + 5 = 9
9 + 50 ÷ 2(5)
50 ÷ 2 = 25
9 + 25(5)
25(5) = 125

The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?
Answer:
$460.20
Step-by-step explanation:
499*15% = 74.85 (total discount price)
499-74.85 = 424.15 (deduct discount from original price)
424.15*8.5% = 36.05275 (total tax from price)
424.15+36.05275 = 460.20275 (add tax to discounted price)

Step-by-step explanation: you have to subtract 80 from 120 to get 40. Then you would have the ratio 40:80. Then when you simplify it would be 1:2.
The visual work:
120-80=40
40:80=1:2
i know u didnt need the explanation and all that but just wanted to show you how i got it- lol
Answer:
Answer down below!
Step-by-step explanation:
If there were 80 blue marbles, but the amount of red marbles isn't stated. First, you need to figure out how many there are. 80 + Number = 120
Number = 40
The ratio is 80:40
Cutting that in half would be 40:20
We're getting closer
20:10
This is starting to get pretty obvious what our answer could be!
If we kept cutting we would get 2:1
Your answer is 2:1!!

What is the equation of the line graphed?
Answer:
y= 3x-2
Step-by-step explanation:
Slope intercept form is y=mx+b. M = slope. B= Y-Intercept
Slope can be found with rise/run, or y/x. The slope in this scenario is 3/1, or 3.
Y-Intercept can be found at (0,-2).

A salesperson’s commission rate is 4%. What is the commission from the sale of $39,000 worth of furnaces? Suppose sales would double. What would be true about the commission?
Answer:
The earnings will double
Step-by-step explanation:
Step one:
given data
we are told that the sales person's earnings is 4% of the sales made.
given that the sales made is $37,000 worth of furnaces.
Step two:
we want to find 4% of $37,000
=4/100*37000
=0.04*37000
=1480
hence for $37,000 the earning will be $1480.
Now suppose sales is doubled that is 37000*2= 74000
we want to find 4% of $74,000
=4/100*74000
=0.04*74000
=2960.
the earnings is $2960.
So if sales doubles the earnings will double

Tatiana is buying b number of books and m number of magazines at the book fair. The books cost $4 each and the magazines cost $2 each. Tatiana's total purchase can be shown with this expression: 4b + 2m. Which expression is equivalent to 4b + 2m?
Answer:
2(2b + m)
Step-by-step explanation:
We can simplify the expression given in the question using factoring:
4b + 2m
(2 x 2)b + (2 x 1)m
2(2b + m)
The equivalent expression is 2(2b + m).
What is meant by an expression?It is a sentence with a minimum of two numbers or variables and at least one math operation.
Given that b is the number of books and m is the number of magazines.
The cost of a book = $4
The cost of a magazine = $2
The given expression for Tatianan's total purchase is 4b + 2m.
The given expression can be simplified as
4b+2m = 2(2b+m)
Hence, 2(2b+m) is the equivalent expression of 4b+2m.

Students in a science class investigated how the speed of sound changes with the air temperature outside. The data are shown in the scatterplot.
Based on the scatterplot, what is the best prediction of the speed of sound when the air temperature is 45°C?
350 m/s
355 m/s
360 m/s
365 m/s
Answer:360 m/s
Step-by-step explanation:
The best prediction of the speed of sound when the air temperature is 45°C is 360 m/s option third is correct also the graph shows a positive correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
As we can see in the graph:
When the air temperature is 10°C the speed of sound is around 337m/s
When the air temperature is 20°C the speed of sound is around 344m/s
When the air temperature is 30°C the speed of sound is around 348m/s
When the air temperature is 40°C the speed of sound is around 355m/s
From the above observation, the air temperature increases the speed of the sound increases.
So when the air temperature reaches 45°C the speed of the sound will be 360 m/s.
Thus, the best prediction of the speed of sound when the air temperature is 45°C is 360 m/s.

What is wrong with this equation 7/9-8/9=1/9
Answer:
the answer would be -1/9
because you're subtracting 8/9 from 7/9, not the other way around.
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
7/9-8/9=1/9
We have a common denominator
( 7-8) 1

7 -8 is equal to -1 not 1
The answer should be -1/9 not 1/9
help meee pleasee !!!
Answer:
It would be relation B and f (x)
Step-by-step explanation:
for it to be a function X (-8) can only have one outcome, however that isn't the case with A.
and I believe if I'm remembering correctly, one-to-one correspondence is each element of one set is only paired with one element of the other set which isn't true for B, so it should be f (x), though you may want to look it up for yourself to make sure.

Oliver is starting a running plan to train for a race. In the first week of his running
plan, Oliver will run 14 miles. The plan calls for Oliver to increase his weekly milage
by 3.5 miles every week. If Oliver sticks to the plan, how many miles would he be
expected to run during his oth week of the training plan?
Answer:
49
Step-by-step explanation:
He starts at 14 miles and will add 3.5 miles to it every week. You are checking how many miles he will run by the 10th week so you would do 3.5 x 10 which equals 35 then add that to 14 to get your total of 49 miles. Have a good day lol
