Answer:
Step-by-step explanation:
-6x-2y= -26
3(-6x-2y)= -26*3
-18x-6y= -78
(subtract this from the first equation)
(-2x-6y)-(-18x-6y)= -14+78
16x=64
x=4
Now that we know x= 4 we can plug that into an equation and solve for y
-2(4)-6y= -14
-8-6y= -14
-6= -6y
y= 1
x=4
y= 1

Answers
Answer: y=-3x-2
Step-by-step explanation:
Slope is rise over run. The slope of y=-3x-2 is -3, which is 1 down/up and 3 to the right/left. The slope of y=-6x+1 is -6 which is 1 down/ up and 6 to the right/left. When the graph is going 3 steps to the right/left, it is steeper than when its going 6 steps to the right/left.

Teresa received a $90 gift card for a coffee store. She used it buying some coffee that cost $8.59 per pound. After buying the coffee, she had $38.46 left on her card. How many pounds of coffee did she buy?
Answers
Answer:
6 pounds of coffee
Step-by-step explanation:
Given Teresa's $90 gift card for a coffee store, and a balance of $38.46 on her card:
Subtract the remaining balance of $38.46 from the $90 original balance on Teresa's card, to determine how much she spent on coffee.
$90.00 - $38.46 = $51.54
Next, divide the amount that she spent at the coffee store by the $8.59 cost per pound to find out how many pounds of coffee she purchased from the store:
$51.54 ÷ $8.59 per pound = 6 pounds
Therefore, she bought 6 pounds of coffee worth $51.54 from the store.

Ms. Failla decides that she wants to give a test on ratios and rates. The test consists of 18 questions. How much time must Mrs. Storz give to her students if she plans that the students can answer the questions at a rate of 3 questions in 7.5 minutes?
Answers
Answer:
Mrs. Storz must give 45 minutes
Step-by-step explanation:
Create a proportion:
t = total time given for all questions
[tex]\frac{3}{7.5} = \frac{18}{t}[/tex]
Cross multiply:
3t = 135
Divide both sides:
3t/3 = 135/3
t = 45

Let's consider the points (0 , -1) and (1 , 2) to find the slope of given line ~
[tex] \dfrac{y_2 - y_1}{x_2 - x_1} [/tex][tex] \dfrac{2 - ( - 1)}{1 - 0} [/tex][tex] \dfrac{2 + 1}{1} [/tex][tex]3[/tex]I hope it helps ~
Answer:
After looking at the image you posted, I deduced that the correct answer should be slope= 3.
Step-by-step explanation:
I came to this conculsion by using the formule slope= [tex]\frac{rise}{run}[/tex] or [tex]\frac{y-axis}{x-axis}[/tex]
Firstly:
I identified the position of the two points. The first points position being (-1, 0) and the second being (1, 2).
Secondly:
I then found the difference between the two points on the graph to be
(1,3) or (x=1, y=3).
Thus:
The [tex]\frac{rise}{run}[/tex] of the two points is [tex]\frac{y=3}{x=1}[/tex] or 3.

Suppose a charity received a donation of $24.1 million. If this represents 29% of the charity's donated funds, what is the total amount of its donated funds?
Round your answer to the nearest million dollars.
Answers
Answer:
$83 million
Step-by-step explanation:
29% of the charity's donated funds.
$24.1 million = donation
Let x = the total amount of donated funds
29/100 • x = 24.1
x = 24.1 • 100/29
x = 83.10

Answer:
x.=6 y=7
Step-by-step explanation:
glad glad I could help
Answer:
x = 6
y = 7
Step-by-step explanation:
Side AB and side DC is equal so let's put it in a equation.
2y - 8 = y - 1
Use APE or Additive Property of Equality\
2y - y = 8 - 1
y = 7
So the value of y is 7.
Now substitute it to line BC.
y + 6
7 + 6
= 13
Since line BC and line AD has equal sides, let's put it in a equation.
2x + 1 = 13
2x = 13 - 1
2x = 12
Use DPE or Division Property of Equality
2x/2 = 12/2
x = 6
