I think y=2x^2+8x-10
In case u don't know ^2 means square so don't put ^2 put the 2 next to the x on top cuz some ppl get confused
hoped I helped!:)

Which value of m will create a system of parallel lines with no solution? y=mx-6 8x-4y=12 A coordinate grid with one line labele
nydimaria [60]

Answer:

A system of parallel lines will be created where the two lines will never meet and have no common solution at a value of m = 2

Step-by-step explanation:

The equation of the given line is 8·x - 4·y = 12

Which gives;

8·x- 12= 4·y

y = 2·x - 3

Given that the line passes through the points (0, -3) and (1, -1), we have;

Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}

When (x₁, y₁) = (0. -3) and (x₂, y₂) = (1, -1), we have;

Slope, \, m =\dfrac{(-1)-(-3)}{1-(0)} = 2

y - (-3) = 2×(x - 0)

y = 2·x - 3 which is the equation of the given line

For the lines 8·x - 4·y = 12, which is the sane as y = 2·x - 3 and the line y = m·x  - 6 to have no solution, the slope of the two lines should be equal that is m = 2

Given that the line passes through the point (1.5, 0), we have;

y - 0 = 2×(x - 1.5)  

y = 2·x - 3...................(1)

For the equation, y = m·x  - 6, when m = 2, we have;

y = 2·x  - 6..................(2)

Solving equations (1) and (2) gives;

2·x - 3 = 2·x  - 6, which gives;

2·x - 2·x=  - 3 - 6

0 = 9

Therefore, a system of parallel lines will be created where the two lines will never meet and have no common solution at a value of m = 2.

A line passes through (4, 5) and (8, 9). Which equation best represents the line?
kipiarov [429]
Slope (m) = change in Y over change in X

change in Y = 9-5 = 4
change in x = 8-4 = 4
slope = 4/4 = 1
 m = 1

the y intercept (b) would be found by using the formula y = mx+b

 find b by replacing y, m and x in the equation with one of the points and the calculated slope:

(4,5)  x = 4, y = 5 and slope m = 1
5 = 1*4 +b
5 = 4+b
b = 5-4
b=1

so the equation of the line would be y = x +1
 the answer is A

A pool was originally a square. The pools length is being increased by 4 feet to make pools new area be 480 square feet. What wa
mezya [45]
Area of a square = Length ^2

480    =   (x+4)^2

√480 = x + 4

21.9     = x  + 4

x          = 17.9
