How do I solve this?
vodomira [7]
I’m assuming what you’re asking here is how to *factor* this expression. For that, let’s rearrange the expression into a more familiar form:

-c^2-4c+21

From here, we’ll factor out a -1 so that we have:

-(c^2+4c-21)

Let’s focus on the quadratic expression inside the parentheses. To find our factors (c + x)(c + y), we’ll need to find two terms x and y that multiply together to make -21 and add together to make 4. It turns out that the numbers -3 and 7 work out perfectly for that purpose (-3 x 7 = -21 and 7 + (-3) = 4), so substituting them in for x and y, we have:

(c + (-3))(c + 7)
(c - 3)(c + 7)

And adding back on the negative from a few steps earlier:

-(c - 3)(c + 7)

Bess [88]

Answer:

The answer in the attached figure

Step-by-step explanation:

Let

x------> the abscissa

y-----> the ordinate

we know that

y=2x -----> given problem

The domain is [-1, 0, 1]

so

For x=-1

y=2(-1)=-2

The point is (-1,-2)

For x=0

y=2(0)=0

The point is (0,0)

For x=1

y=2(1)=2

The point is (1,2)

RS has a midpoint at M(7, 10). Point R is at (8, 10). Find the coordinates of point s.
Elena L [17]

Answer:

S(6, 10)

Step-by-step explanation:

1. The Midpoint (in this case, M) will always be halfway between both R and S (or other characters in some cases).

2. As M is only one X value away from R, it is only 1 X value from S as well, but in the other direction.

3. (7, 10) - (1, 0) = (6, 10)

The (7, 10) is the Midpoint Coordinates.

The (1, 0) is the distance from M to R.

The (6, 10) is the coordinates of S.
