Eva is working two summer jobs, making $16 per hour tutoring and $8 per hour clearing tables. Last week Eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Graphically solve a system of equations in order to determine the number of hours Eva worked tutoring last week, x,x, and the number of hours Eva worked clearing tables last week, yy.
Answers
Answer:
48 and 32 6 hours clearing tables and 2 hours tutoring
Step-by-step explanation:
we can rewrite this as a fraction. we will use 1/10s because 80 can be divided by 8 which is in the problem. we then have to find out what two numbers add up to 8 but one is 3 times the other. 6 and 2 fit into this problem so we plug it into the equation and we write it as this 6x+4x=80 where x is 8. we get 48 and 32.

How do I find domain and range.
Answers
Answer:
The domain is all the x values and the range is all the y values.
Since there are 6 points on the figure, just find the coordinates (x, y) for all the points. Then get all the x and y values separated in a table.
I'm just going to assume this is scaled by 1 unit per square
Here are all the points on the graph:
(-6, -1)
(-4, 3)
(-4, -6)
(0, 2)
(2, -2)
(5, 7)
Now just split them into their x and y values
The Domain: -6, -4, 0, 1, 5
The Range: -1, 3, -6, 2, -2, 7
Answer:
Interval notation
Domain: [-6, 5]Range: [-1, 7]Step-by-step explanation:
The domain is the x-value on the x-axis. The range is the y-value on the y-axis.
Find the two highest points on opposite sides in the graph.
find the x-values (refer to the image below)find the y-values (refer to the image below)After this step has been completed, you can write it in different forms, for example in interval notation:
The domain would be [-6, 5]
The range would be [-1, 7]
Note - for interval notation, when the point is a closed circle, the ending parenthesis would be "[ "or "]". However, when it is an open circle, the parenthesis would be "( "or ")".

1. Andrew paid $10 for a burger. The burgers went on a sale and there was a discount of 20%. What was the sale price of the burgers?
2. Abby Matthews, store manager for Macy’s, does not know how to price a refrigerator that cost $900. She knows her boss wants a %140 mark up on the cost. Help Abby markup the cost of refrigerator.
Answers
Answer:
12, 1260
Step-by-step explanation:
Andrew paid $10 for a burger. The burger had a discount of 20%. This means that the $10 is 80% of the original price.
100% - 80% = 20%
To find the original price, you can multiply by 120%
10 * 120% = 12
Abby Matthews needs to mark up a refrigerator that costs $900 to 140% of the original price. To do this, you can directly multiply.
900 * 140% = 1260

If you can buy 10 juice packs for $3.00, how much will you spend to buy 4 juice packs?
please answer asap
Answers
Answer:
Step-by-step explanation:
1. 3 cans cost 90 cents
3=0.90 & x=2.7
by ratio:
3/0.9 = x/2.7
0.9x=8.1
x= 9
So you can buy 9 cans for 2.7 dollars
2. 10 Juice cost 3 dollars
by ratio:
10/3 = 4/x
10x=12
x=1.2
so you will spend 1.2 dollars to buy 4 juice packs
