Answer:I think it would be the grocery store is at (-4, -8) but I not sure
Step-by-step explanation:
Answer:
Step-by-step explanation:
9-3= 6 units (since x coordinates are same). We can also show by manually counting the squares (1 square= 1 unit)
Yes, its greater. Distance from house to school is 6. Distance from school to grocery is 3-(-8)= 11. Thus, distance is 11+6= 17 units.
Distance from house to school is 6. Distance from school to community center is 1-(-4)=5. Thus, distance= 6+5=11 units.

Explain how you would work backward to solved the problem
Answers
Answer:
a. 2116 miles
b. 105.8 gallons
c. $305.76
d. cost per gallon = total cost / number of gallons = total cost/105.8
Step-by-step explanation:
a.The round-trip distance is the sum of the distances there and back. It is double the one-way distance.
round-trip distance = 2 × one-way distance
round-trip distance = 2 × 1058 miles = 2116 miles
__
b.The gas used will be the distance divided by miles per gallon.
gas used = round-trip distance / miles-per-gallon
gas used = (2116 mi)/(20 mi/gal) = 105.8 gal
__
c.The cost of gas will be the product of cost per gallon and number of gallons.
cost of gas = cost-per-gallon × gallons
cost of gas = $2.89/gal × 105.8 gal = $305.762 ≈ $305.76
__
d.The relation used in the previous step can be used to find the cost per gallon. Divide that equation by gallons to get ...
(cost of gas)/gallons = cost-per-gallon
For the same trip, the number of gallons is 105.8, so the equation becomes ...
cost-per-gallon = (cost of gas)/105.8

A couch and coffee table cost a total of $1272. The cost of the couch is two times the cost of the coffee table. Find the cost of each item.
Answers
Answer:
318+954
Step-by-step explanation:
divide 1272 by 2 to get what they would cost if they were the same amount then divide that by 2 to get 318 times that by 3 to get 954 and add 318 to get 1272
The required cost of the couch and coffee table is $848 and $424 respectively.
Given that,
A couch and coffee table cost a total of $1272. The cost of the couch is two times the cost of the coffee table.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
let the cost of the coffee table be x,
Now the cost of the couch = 2x
According to the question,
2x + x = 1272
x = 424
now,
Cost of the couch = 424 [2] = 848
Thus, the required cost of the couch and coffee table is $848 and $424 respectively.

Consider the equation 6 x 3 y = 9. Which equation, when graphed with the given equation, will form a system with infinitely many solutions? y 2 x = 3 y 2 x = 9 y = 2 x 3 y = negative 2 x 9.
Answers
The equation, when graphed with the given equation that will form a system with infinitely many solutions is 2x + y = 3
Given the equation 6x + 3y = 9, the equation if when graphed with this equation will give an infinite number of solutions must be the same as the given equation.
Note that the coefficient of the variables may be different by a scale factor.
To get the required equation, we will divide the equation through by 3 as shown;
6x + 3y = 9Divide through by 3;
6x/3 + 3y/3 = 9/3
2x + y = 3
Hence the equation, when graphed with the given equation that will form a system with infinitely many solutions is 2x + y = 3

x = negative 4 y + 19
x = StartFraction negative 2 y + 17 Over 3 EndFraction
4 y = negative x + 19
Answers
Answer:
x = -4y + 19
Step-by-step explanation:
We have the two equations 3x + 2y = 17 and x + 4y = 19.
The first step would be to rearrange the variables in the second equation so we have a defined expression for x. We would want to do this so we could then plug in the the defined expression for x into the other equation and solve for the other variable.
x + 4y = 19
We can rearrange this by getting the 4y to the other side.
We can get 4y on the other side by subtracting 4y from both sides
x + 4y - 4y = 19 - 4y
x = -4y + 19

Answers
n = 4
Since you divide 6 by 3 to get 2, you divide 12 by 3 and you get 4.
Answer: 4
Step-by-step explanation: This problem is already set out as a proportion. you can cross multiply 6 times n which gives you 6n. Then 12 times 2 which gives 24.
Now you have 6n = 24. You can divide right away, or think of a number when you multiply into 6 gives you 24. Its obvious the answer is 4 because 6 x 4 = 24.

6/12 = 1/2
