Hello,
y-3x=2==>x=(y-2)/3
==>(x+1)²=((y-2)/3+1)²=(y+1)²/9
y=(x+1)²-5
==>y=(y²+2y1)/9 -5
==>y²-7y-44=0 ; Δ=7²+4*44=225=15²
==>y=(7+15)/2 or y=(7-15)/2
==>y =11 and x=(11-2)/3=3
or y=-4 and x=(-4-2)/3=-2
sol={(3,11);(-2,-4)}
For the horizontal segment, the value of the ordinate will not change. Then the second point will be (x, 3.5).
<h3>What is coordinate geometry?</h3>
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The point is given as (3, 3.5).
Then name a second point so that the two points form a horizontal segment.
For the horizontal segment, the value of the ordinate will not change.
Let x be the abscissa.
Then the point will be given as (x, 3.5).
More about the coordinate geometry link is given below.

Answer:
Step-by-step explanation:
a. Y=50x+75
b. Y=50(7)+75
y=350+75
y=425
Yes, you will have enough if you use the 465 certificate. You will have $40 (465-425) left on the gift certificate.
Jeweler A: 125, 140, 155, 170, 185, 200
Jeweler B: 140, 152, 164, 176, 188, 200
If you count the hours it would be after 5 hours that they would be the same exact amount. The two jewelers would be paid $200.00 after 5 hours.
Sorry if I did anything wrong. Comment if I left something out or you don't understand.
