Answer:
1. 0, 2. -1/2, 3.undefined, 4. -5/3, 5. 6, 6. -2, 7. 23/17
Step-by-step explanation:
y2 - y1 / x2 - x1
1. -18 - -18 / 15 - 6 = 0
2. 16 - 12 / 0 - 8 = -4/8 = -1/2
3. 37 - 2 / -15 - -15 is undefined (can't have 0 as denominator)
4. 30 - 20 / -5 - 1 = 10 / -6 = -5/3
5. -36 - -12 / 4 - 8 = -24 / -4 = 6
6. - 23 - -15 / 11 - 7 = -8 / 4 = -2
7. 100 - 54 / -38 - -72 = 46 / 34 = 23/17
The triangle below has sides of 4 meters, 7 meters, and 6 meters.

Step-by-step explanation:
A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.

There are a few different ways to compute the ratio of fractions. The one we used here may be a little unusual. All are equivalent.

A.slope = 6, y-intercept = -1/3
Step-by-step explanation:
Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9
Answer:
Equation: I believe its y=5/3x-13
Step-by-step explanation:
In the "y=5/3x+9" equation, 5/3 is the slope. You then take the slope (5/3) and the points (9,2) and add it to the equation "y+y1=m(x-x1)":
y-y1=m(x-x1)
distribute 5/3: y-2=5/3(x-9)
y-2=5/3x-45/3
y-2=5/3x-15
-add 2 on both sides-
y=5/3x-13
I might be wrong- but its worth a try ;-;

Enrique has to pay 80% of a $200 phone bill. Explain how to use equivalent ratios to find 80% of $200.
(U need to write a paragraph)
Answer:
First, write 80% as 80100. Then write an equivalent ratio that has the answer in the numerator and 200 in the denominator. 100 x 2 is 200, so 80 x 2 will be the answer. 80 x 2 = 160. The answer is $160.

(PLEASE HELP, BRAINLIEST IF CORRECT) A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answer:
40 nickels
Step-by-step explanation:
1 2/5 to 2 1/3 = 7/5 : 7/3
= 21/15 : 35/15
21/15 = 24
35/15 = x
(35/15 * 24) / 21/15
∴ 56 ÷ 21/15
= 40 nickels

That equation is in slope intercept form y = mx+b
m = -1/4 is the slope
b = -7 is the y intercept
At the dealership where she works, Denise fulfilled 1/2 of her quarterly sales goal in January and another 5/12 of her sales goal in February. What fraction of her quarterly sales goal had Denise reached by the end of February?
Answer:
She has fulfilled about 91.6666 repeating
Step-by-step explanation:
If half of her sales were fulfilled in January, then that is 50% or 0.5. Then if you take 5/12 then it = 0.41666666, add the two decimals together and you have 0.916666 repeating. If you want to turn that into a fraction it would be 9/10 by rounding down due to the decimal.
Answer:
the answer will probably be around 1 / 12
Step-by-step explanation:
hope this helps! (if not then its okay)
