Which point-slope form passes through the point (-2, -1) and has slope 5?

Mathematics
1 answer:
guajiro [1.7K]3 years ago

Answer:

D. (y+1)=5(x+2)

Step-by-step explanation:

Point-slope form follows: y - y1 = m(x - x1)

Since both x and y are negative for (-2,-1), it becomes a positive because two -'s become a +.

m(slope)=5

y-(-1)=5(x-(-2))

y+5=5(x+2)

E is the midpoint of DF, DE = 2x + 4, and EF = 3x + 1. Find DE, EF, and DF.
Agata [3.3K]
When there is a midpoint in a line segment, the two segments that are then produced have to be equal. So that means that because E is a midpoint of DF, DE=EF.
Set up the equation.
DE=EF
2x+4=3x+1
Then solve for x.
x=3
Then plug it back in the equation to find DE and EF.
DE=2x+4=2(3)+4=10
Because DE=EF then EF is also 10.
DF is made from the addition of DE and EF so DF is twice EF.
DF= 20

DE= 10, EF= 10, DF= 20

Hope this helps.

Can someone help me find the functions zeros
Amiraneli [1.4K]

\bf g(x) = 2(x-3)^2-8\implies \stackrel{g(x)}{0}=2(x-3)^2-8\implies 8=2(x-3)^2 \\\\\\ \cfrac{8}{2}=(x-3)^2\implies 4=(x-3)^2\implies \pm\sqrt{4}=x-3\implies \pm 2 = x-3 \\\\\\ \pm 2 +3 = x\implies x = \begin{cases} 5\\ 1 \end{cases}
