What is the y-intercept of the graph that is shown below? On a coordinate plane, a line goes through points (0, 2) and (3, 0). (–3, 4) (0, 2) (2, 0) (3, 0)
Answer:-2/3
Step-by-step explanation:the problem is asking for the slope of (0,2) and(3,0). The formula for this problem is y2-y1 over x2-x1. And if your writing this formula down write it like a fraction with y on top and x on bottom. (x,y) (x2,y2). You take the 0 from the second set and the 2 from the first set and subtract them to get -2. Then you take the 3 from the sea d set and the 0 from the first set and you subtract them to get 3. That’s how you get the answer of -2/3.

Step-by-step explanation:
A jewellery shop sells 240 necklaces in a month. 18 of the necklaces were sold via the shop's website, the rest were sold in high street shop. Work out the ratio of the online sales to shop sales. Give you answer in its simplest form.
Answer: 3 : 37
Step-by-step explanation:
The shop sold 240 necklaces in a month.
Out of these, 18 were sold online.
The number that was sold offline was therefore:
= 240 - 18
= 222 shop sales
The ratio of online sales to shop sales is therefore:
18 : 222
Take it to simplest form by dividing both sides by their highest common factor of 6:
3 : 37

Which sets of ordered pairs show equivalent ratios?. Check all that apply. (1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)
Answer:
(2, 2) ; (4, 4) ; (6, 6)
(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)
Step-by-step explanation:
(1, 2), (2, 3), (4, 7) (2, 2), (4, 4), (6, 6) (3, 1), (4, 1), (5, 1) (4, 1), (8, 2), (12, 3) (2, 1), (4, 3), (5, 4)
Evaluating the ratio of each pair :
(1, 2) = 1/2 = 0.5
(2,3) = 2/3 = 0.67
(4, 7) = 4/7 = 0.57
(2,2) = 2/2 = 1
(4, 4) = 4/4 = 1
(6, 6) = 6/6 = 1
(3, 1) = 3 /1 = 3
(4, 1) = 4 / 1= 4
(5,1) = 5 / 1= 5
(4, 1) = 4 / 1 = 4
(8, 2) = 8/2 = 4
(12,3) =12/3 = 4
(2, 1) = 2/1 = 2
(4,3) = 4 / 3 = 1.33
(5, 4) = 5 / 4 = 1.25
Pairs with equivalent ratios :
Ratio of 1;
(2, 2) ; (4, 4) ; (6, 6)
Ratio of 4:
(4, 1) ; (4, 1) ; (8, 2) ; (12, 3)

To make punch for the class party, Mrs.Lui mixed 1 and 1/3 cups orange juice, 3/4 cup apple juice, 2/3 cup cranberry juice, and 3/4 cup lemon-lime soda. Mixed together, how many cups of punch does the recipe make?
Answer: 3 1/2
Step-by-step explanation: First you have to convert the fractions so that they all have the same denominator. Using 12 will be the easiest. 1 and 1/3 equals 16/12 because 1/3 equals 4/12 and 1 equals 12/12. 3/4 equals 9/12. 2/3 equals 8/12. And 3/4 equals 9/12 again. 16/12 plus 9/12 plus 8/12 plus 9/12 equals 42/12. 42/12 in the simplest form would be 3 and 1/2, because 42 divided by 12 is 3.5.
The difference between the length and width of a rectangle is 4 units. The perimeter is 40 units. Enter and solve a system of equations to determine the length and width of the rectangle. (Hint: The perimeter of a rectangle is 2l + 2w.)
Answer:the length and width of the rectangle are 12 and 8 respectively
Step-by-step explanation:
Step 1
The perimeter of a rectangle is 2l + 2w where l= length and w= width giving us that
2l+2w=P
2l + 2w = 40
2(l+w)= 40
l +w = 20
Also we were given The difference between the length and width of a rectangle is 4 units giving us that
l-w= 4
Here our systems of equation to solve the problem
l-w= 4----- Equation 1
l +w = 20-----Equation 2
Step 2
I-w=4---- Equation 1
l +w = 20---Equation 2
Adding equation 1 and 2
I-w=4
+l +w = 20
2l =24
l=24/2
=l=12
To find w, we put the value of l=12 into equation 1
I-w=4
12-w= 4
w= 12-4
w=8
Therefore the length and width of the rectangle are 12 and 8 respectively
True or False? -|7| = |-7|
Explain please.
Answer:
False
Step-by-step explanation:
Notice how the negative symbol is outside the first number and inside the first number. If the negative symbol is outside the absolute value, the number will remain negative. If the negative symbol is inside the absolute value, the number will turn to positive.
Best of Luck!

Mr. Chen drives 26 miles to work every day. He drives the same distance to get back home. How many miles does he drive during a 5-day work week
Answer:
260 miles
Step-by-step explanation:
Given that,
Total distance driven by Mr. Chen everyday = 26 miles
He drives the same distance to get back home.
It means total distance driven by Mr. Chen to go and come back = 2(26) = 52 miles
We need to find how many miles does he drive during a 5-day work week.
Total distance = 5×52
= 260 miles
Hence, he will drive 260 miles during a 5 day work week.
