Factor the expression below.
Gnom [1K]

Answer:

A. (x-5)(x-5)

Step-by-step explanation:

We need to factor x^2-10x+25 into the form (x+y)(x+y) where 2y=-10 and y^2=25

2y=-10

y=-5

So this becomes (x-5)(x-5)

Hope this helped!

Write an equation of a line in point-slope, slope-intercept, and standard form that has
Inga [223]

Answer:

(a) y + 4x - 14 = 0

(b) y = -4x + 14

(c) y + 4x = 14

Step-by-step explanation:

The formula for calculating the equation of line in point - slope form is given as :

y-y_{1}  = m(x-x_{1} )

where m is the slope

Given from the question :

m = - 4

x_{1} = 2

y_{1} = 6

Substituting into the formula , we have :

y - 6 = - 4(x - 2)

y - 6 = -4x + 8

y + 4x - 6 - 8 = 0

y + 4x - 14 = 0

Therefore :

(a) the equation of the line in point - slope form is y + 4x - 14 = 0

(b) to write it in slope - intercept form , we will make y the subject of the formula , which will give : y = -4x + 14

(c) the equation of line in standard form is ; y + 4x = 14

HELP ASAP!!! I SUCK AT MATH AND I DON’T understand this!!!
anyanavicka [17]

Answer:

Part A:

\frac{13}{20}

Part B:

\frac{1}{39}

Step-by-step explanation:

The total number of candies is 40.

10 + 14 + 4 + 12 = 40

14 are Butterfinger and 12 are Crunch.

14 + 12 = 26

\frac{26}{40}

\frac{26}{40}=\frac{26/2}{40/2}=\frac{13}{20}

\frac{10}{40} =\frac{10/10}{40/10} =\frac{1}{4}

40 - 1 = 39

\frac{4}{39}

\frac{1}{4} × \frac{4}{39}

\frac{1}{39}
