Answer:

Step-by-step explanation:

y=5x-2

slope of the line is 5 because if we compare to

y=mx+b where m is the slope we see m=5

Points (0,-2), (2,8), (4,18)

slope between the points (0,-2), (2,8)

m=(y2-y1)/(x2-x1) = -2-8/0-2 = -10/-2 = 5

slope between the points (4,18), (2,8)

m=(y2-y1)/(x2-x1) = 18-8/4-2 = 10/2=5

slope between the points (4,18), (0,-2)

m=(y2-y1)/(x2-x1) = 18+2/4-0= 20/4 =5

From delta math:<br> Subtract -2x^2 + 3x - 9 from 8x^2 + 10x - 10

Leto [7]

Answer:

$10x^2 + 7x - 1$

Step-by-step explanation:

Step 1: Build the expression in numerical form.

$(8x^2 +10x - 10) - (-2x^2 + 3x - 9)$

Step 2: Distribute the negative sign.

$8x^2 +10x -10 + (-1)(-2x^2) + (-1)(3x) + (-1)(-9)$
$8x^2 + 10x - 10 + 2x^2 + (-3x) + 9$

Step 3: Combine like terms.

$(8x^2 +2x^2) + (10x -3x) + (-10+9)$
$10x^2 +7x -1$

Therefore, the answer is $10x^2 + 7x -1$ .
