Is each expression equivalent to 2x^2 - 50?
puteri [66]
We would first determine how to solve this, and then from there, we would then see whether the following answer would be the correct answers.

2x^2 -  50 \\ \\ Pull \ out \ like \ factors : \\ 

   2x^2 - 50  =   2 * (x^2 - 25) \\ \\    Factoring: \\    x^2 - 25 \\ \\ (your \  answer)...\\ \\   2 * (x + 5) * (x - 5)

Now, we can determine whether the say "yes" or "no" to the following answers.

<span>a 2(x-5)(x+5) = YES
b -2(x+5)(x+5) = NO
c -2(5-x)(x+5) = NO</span>

Answer please cuz I'm very confused
Anestetic [448]

5x + 3y = - 53

the equation of a line in ' slope- intercept form ' is y = mx + c

where m is the slope and c the y-intercept

rearrange 3x - 5y = - 15 into this form to obtain m → (subtract 3x from both sides)

- 5y = - 3x - 15 → divide all terms by - 5 )

y = \frac{3}{5} x + 3 → in slope-intercept form with m = \frac{3}{5}

given a line with slope m then the slope m₁ of a line perpendicular to it is

m₁ = - \frac{1}{m} = - 1 ÷ \frac{3}{5} = - \frac{5}{3}

partial equation is y = - \frac{5}{3} x + c

to find c substitute ( - 7, - 6) into the partial equation

- 6 = \frac{35}{3} + c ⇒ c = - 6 - \frac{35}{3} = - \frac{53}{3}

y = - \frac{5}{3} x - \frac{53}{3} → in slope intercept form

multiply all terms by 3

3y = - 5x - 53 → ( add 5x to both sides )

5x + 3y = - 53 → in standard form
