Answer:
For A, the answer is D, y=-x+2, and for B, the answer is C, (2,1)
Step-by-step explanation:
The answer for question A is justified by the fact that the graph is negative, so x is -x, but there is a positive y-intercept so it is a +2 y-intercept. For question B, I just graphed it on desmos and looked for all the points , and (2,1) is the only one on the line.

Step-by-step explanation:
This summer, Silvia has been selling lemonade for $9 per cup. If Silvia has sold 19 cups so far, how much money has she made?
Answer:
$171
Step-by-step explanation:
Price of lemonade = $9 per cup
Quantity sold = 19 cups of lemonade
Revenue = price of the product × quantity of the product sold
Silvia's total revenue = price × Quantity
= $9 × 19 cups
= $171
Silvia has made a total of $171 from selling 19 cups of lemonade at $9 each

22-3 (x-70) = x+20
please help
Answer:
x = 53
Step-by-step explanation:
22 - 3 ( x - 70 ) = x + 20 Multiply out
22 - 3x + 210 = x + 20
22 + 210 - 3x = x + 20
232 - 3x = x + 20
232 - 3x + 3x = x + 3x + 20
232 = 4x + 20
232 - 20 = 4x + 20 - 20
212 = 4x
212/4 = 4x/4
212/4 = x
x = 53
Answer:
Step-by-step explanation:22-3(x-70)=x+20
22-3x+210=x+20
22+210-3x+3x=x+3x+20
232=4x+20
4x=232-20
X=53

Answer: Slope = -7/5
=========================================================
Explanation:
Pick any two rows you want. I'll select the first two rows.
Each row represents an (x,y) point
The first row means (-8,55) is one point and the second row means (2,41) is another point.
Use these two points in the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (41-55)/(2- (-8) )
m = (41-55)/(2 + 8)
m = -14/10
m = -7/5 is the slope
The negative slope means the line goes downhill as you move from left to right.
Specifically, every time it drops 7 units the line moves over to the right 5 units.
slope = rise/run = -7/5
rise = -7, negative rise means we go down 7 spaces
run = 5 means we move to the right 5 spaces

4.06/x = 0.18/0.5 please could you answer
Answer:
x=203/18
Step-by-step explanation:
convert the decimal into a fraction
203/50/x = 9/50 / 1/2
simply the complex fraction:
203/50x = 9/25
cross multiply
450x = 5075
divide both sides by 450:
x= 203/18
Answer:
X=11.2778
Step-by-step explanation:
4.06/X=0.18/0.5
cross multiply
0.18×X=4.06×0.5
0.18X=2.03
divide both sides by 0.18
0.18X/0.18=2.03/0.18
it becomes
X=2.03/0.18
X is therefore 11.2778
