Answer:
(-4,-8)
Step-by-step explanation:
The solution to the system of equations is,
⇒ (- 4, - 8)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expressions are,
⇒ y = 1/2x - 6
⇒ x = - 4
Now, We can simplify the expression for y as;
⇒ y = 1/2x - 6
Put x = - 4;
⇒ y = 1/2 × - 4 - 6
⇒y = - 2 - 6
⇒ y = - 8
Thus, The solution to the system of equations is,
⇒ (- 4, - 8)

There are two possible offers that could be applied to orange juice that would each explain this reduction in the total bill. 4: What are these two offers? 5: What are the other two offers that could explain the reduction in the total bill?
Incomplete question. The full question read;
My local store sometimes runs offers on some of its products. There are three different types of offers that could be in place:
Buy a certain number of a particular product and get an extra one for half price.A percentage discount (always a multiple of 5%) on one particular product.A percentage discount (always a multiple of 5%) on purchases worth a total of more than $10.The store only ever has one of these offers in place at any time.
Last week I bought
3 cartons of orange juice for $4 each1 loaf of bread for $35 packets of snacks for $1 eachThis week I bought the same set of items, but only paid $18 even though the individual items still had the same price.
(4) There are two possible offers that could be applied to orange juice that would each explain this reduction in the total bill.
What are these two offers?
(5) What are the other two offers that could explain the reduction in the total bill?
Answer:
1. Buy a certain number of a particular product and get an extra one for half price
Step-by-step explanation:
By buying 2 and getting one at half the price matches the offer:
Buy a certain number of a particular product and get an extra one for half price.This means two (2) cartons of orange juice cost $8 (4*2) + $2 cost the extra one at half price.
What is the slope of y= -x +7?
Answer:
-1
Step-by-step explanation:
Think of the slope as the number in front of x
Answer:
the slope is the value multiplied by x , so the slope is −1 . We know the y -intercept is b , or −7 , so it is at (0,−7) .
Step-by-step explanation:

a farmer sells his corn for $230 a metric ton with a small surcharge of $25. his neighbor sells her corn for $230 a metric ton and gives $15 rebate. write the cost model equations for both farmers and find the amount of corn that makes the costs equal.
Step-by-step explanation:
Step one:
The farmer sells his corn for $230 a metric ton
small surcharge = $25.
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x+25--------------1
The neighbor sells her corn for $230 a metric ton
he gives $15 rebate------A rebate is a partial refund of the cost of an item
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x-15----------------2
Step two:
Equating the two equation above
230x+25=230x-15
230x-230x=25+15
0=40
The result shows that based on the cost function of both farmer, there will never be an amount of corn that would make them have the same cost
The selling price of an item is $360. After 6 months of not selling, it is marked down by 10%. After another 6 months of not selling, it is further marked down by 20%. Find the sale price after both markdowns.
Answer:
1st markdown = $324
2nd markdown = $259.20
Step-by-step explanation:
current price = 360
1st 6 months = 10% down
= 90% of 360
= 324
2nd 6 month = 20% down of first 6 month
= 20% down of 324
= 80% of 324
= 259.20

Leanna opens a savings account with an initial balance of $100. She then
deposits $50 each month. She currently has $450. How many months has she
been saving for?
Answer:
7
Step-by-step explanation:
450-100=350
350/50=7
7 months
Leanna has been saving for 7 months to have the balance of $450.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as linear equation in one variable.
Let's suppose the Leanna has been saving the money for 'x' months
It means total months = x
Intial balance = $100
Each month she deposit = $50
After x months she will have = $450 (with initial balance)
We can frame a linear equation in one variable such that:
50x = 450 - 100 (without initial balance)
50x = 350 (divide by 50 on both sides)
x = 7 months
Thus, Leanna has been saving for 7 months to have the balance of $450.

Gabebuysanalarmclockpricedat$25.Ifthesalestaxis10%,howmuchtaxwillGabepay?
Hello!
$2.50Original price: $25
If sales tax is 10%, we can use multiplication to find the final price.
Convert 10% to a decimal:
10 / 100 = 0.1
Multiply 25 by 0.1 to solve:
25 × 0.1 = $2.5.

6 IN OUNCES 170 IN GRAMS
Step-by-step explanation:
Answers:
6 ounces
170 grams
===============================================
Explanation:
Through either memorization or using a reference sheet, you should find that 1 ounce is approximately 28.35 grams.
Multiply that by 6 and we see that 6 ounces is about 6*28.35 = 170.1 grams, which rounds to 170 grams.
So overall, 6 ounces = 170 grams approximately.

how do i simplify this equation?
Answer:
-6 = m (i'll show my work below)
Step-by-step explanation:
-6(m-7) + 7 = -8m + 37
-6m + 42 + 7 = -8m + 37
-6m + 49 = -8m +37
-37 = -37
-6m + 12 = -8m
+6m = +6m
12 = -2m
/-2 = /-2
-6 = m
Each correct answer is worth 134 points, and each incorrect answer is worth −14 points.
If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?
Answer:
He scores 7464 points
Step-by-step explanation:
58x134= 7772
22x(-14)= -308
7772-308= 7464
Hope this helps :D
Answer:
Nevan scores 7464 points total.
Step-by-step explanation:
You multiply 58 x 134 to find out how many points he got for the correct answers. He got 7772 points.
You multiply -14 x 22 to find out how many points he lost for the incorrect answers. He lost -308 points.
Subtract 7772-308 to find the total amount of points Nevan has now. He has 7464 points.
Note:
To find out if he won or not I would need a specific number to compare his points with. This is why my answer doesn't say whether he won or not.

Solve for r.
19 = 7 − –3r
Answer:
4
Step-by-step explanation:
19 = 7 + 3r
12 = 3r
4 = r
Answer:
r = 4
Step-by-step explanation:
19 = 7 - -3r
19 = 7 + 3r
Then you do Inverse Operations So you have to Subtract
19 - 7 = 12
12 = 3r
Then you do Inverse Operation So you have to Divide
12/3 = 4
So
19 = 7 - -3(4)
So Let's Make Sure That It Is Correct
19 = 7 - -3(4)
19 = 7 - -12
19 = 7 + 12
So 4 Is The Correct Answer
