I need help with this question! Will mark brainliest :)
Answer:
A. -1/5
B. 8 gallons
C. 75 miles driven
Step-by-step explanation:
Part A is essentially just asking for the slope, which is written as a fraction with the numerator being the number of units the line goes up/down and the denominator being the number of units the line goes left/right. Because the line is going down from left to right, the slope is negative. The slope is -1/5.
Part B can be answered by simply looking at the graph and seeing where the line is at above 175 miles, which is 8 gallons.
Part C can be answered in the same way as Part B, by looking at where the line is at when level with 12 gallons, which is 75 miles driven.
2 pens in each pack of black pens
5 pens in each pack of red pens
6 pens in each pack of green pens

number of packs sold of black, red and green pens = 7 : 3 : 4
A total of 212 were sold.
work out the number of green pen solds
Answer:
24
Step-by-step explanation:

Jim needs to divide 762 coupon books equally among 9 stores. In which place is the first digit of the quotient? Select the word that makes the sentence true. The first digit of the quotient is in the ones place.
Answer:
ones
Step-by-step explanation:
It is given that Jim wants to divide 762 coupons equally among 9 stores.
So dividing 762 by 9, we get
[tex]$=\frac{762}{9}$[/tex]
= 84.66
The position of the digit before the decimal place start with 'ones' and then proceeds to tens, hundreds, thousands, etc.
Therefore, the first digit of the quotient is in the ones place of the position value or place value.

HELP ME PLEASE !!!!!!!
Answer:
93-30=3
Step-by-step explanation:
Mr. Ciullo says he ordered the same amount of bananas each month for his grocery store last year, and the number of pounds ordered each month is a whole number. The produce company says he ordered $6,150 pounds of bananas last year. Does the produce company agree with Mr. Ciullo?
Answer:
No
Step-by-step explanation:
No, the produce company does not agree with Mr. Ciullo. There are a total of 12 months in a year and Mr. Ciullo claims that he ordered a whole number of bananas each month. Therefore, if we divide the total amount in pounds that the produce company claims that Mr. Ciullo ordered last year by the twelve months in the year then the result should be a whole number...
6,150 lbs. / 12 = 512.50 lbs.
We can see that the produce company is claiming that Mr. Ciullo ordered 512.50 pounds per month last year, which is not a whole number and therefore contradicting Mr. Ciullo's statement.

jy=39x + 45
Answer: Its 39x + 45
Step-by-step explanation:
yes
A variable needs to be eliminated to solve the system of equations below. Choose the
correct first step.
- 4x – 2y = 18
4x – 4y = -36
O Subtract to eliminate x.
O Subtract to eliminate y.
O Add to eliminate x.
O Add to eliminate y.
Step-by-step explanation:
-4x - 2y = 18
+ (4x - 4y = -36)
=> -6y = -18, y = 3
As we added the equations together, we have eliminated x and found y.
Hence the correct answer is "Add to eliminate x".

Liz wants to buy a shirt for $25 how much will Liz’s shirt cost in a total if sales tax is 4%
26$
Step-by-step explanation:
1% = 4/100 * 25
1% = 1
25 + 1 = 26
Another way to solve
Percentage increase = 100% + 4%
104/100 = 1.04
1.04 * 25 =26

Given the following function, find f(-5), f(0), and f(3).
f(x)=x? + 3
f(-5)=
f(0) =
f(3) =
Answer:
f(-5)= -2
f(0) = 3
f(3) = 6
Step-by-step explanation:
f(x) = x + 3
f(-5) = -5 + 3
= -2
f(0) = 0 + 3
=3
f(3) = 3 + 3
=6
Circumference of the circle
Step-by-step explanation:
The formula for calculating a circle's circumference is πd, where π is an irrational number (3.14....) and d is the diameter of the circle.
In the circle with diameter 19.5cm, the circumference is around 3.14 * 19.5cm = 61.23cm. (A)
Answer:
61.2
Step-by-step explanation:
circumference= 2πR
r=d/2
r= 19.5/2
r=9.75
circumference= 2×3.14×9.75
circumference= 61.2
Find the two square roots of 144.
Answer:
The square root function
sqrt(144) or √144 produces a single positive value, 12.
However if you have an equation
x² = 144, then you have two possible values for x, 12 and -12.
Two ways to look at it.
x² - 144 = 0
Difference of two squares
(x+12)(x-12) = 0
x = -12, 12
x² = 144
x = ±√144
x = ±12
x = -12, 12
Answer:
12 and -12
Step-by-step explanation:
144 is a perfect square which means that a number multiplies to it with the same number. In this instance both 12 and -12 equal 144.
12 x 12 = 144
-12 x -12 = 144 (two negatives equal a positive)

Answer:
7. y = f(x +2) -7
8. y = -f(x -5)
9. y = f(-x) +3
Step-by-step explanation:
The general transformation can be written ...
y = a·f(b·(x -c)) +d
'a' is the vertical expansion factor. A negative value means the graph is reflected over the x-axis.
'b' is the horizontal compression factor. A negative value means the graph is reflected over the y-axis.
'c' is the number of units of right-shift.
'd' is the number of units of up-shift.
__
7. 2 left and 7 down means (c, d) = (-2, -7), so the transformed function is ...
y = f(x +2) -7
__
8. reflected over x and 5 right means (a, c) = (-1, 5), so the transformed function is ...
y = -f(x -5)
__
9. reflected over y and up 3 means (b, d) = (-1, 3), so the transformed function is ...
y = f(-x) +3
_____
The graph shows an asymmetrical function that makes it possible to tell what the transformations are. The original is dashed orange. The various y-values correspond to the problem numbers. You can see that the transformations match the problem statements.
Find tan θ if sec θ = square root of thirty seven divided by six and sin θ < 0.
Answer:
