Solve the system of equations using elimination 3c - 8d =7 and c + 2d = -7
mario62 [17]

Answer:

d=-2 c=-3

Step-by-step explanation:

3c-8d=7

4(c+2d=-7)

3c-8d=7

4c+8d=-28

4c+3c-8d+8d=7-28

7c=-21

c=-3

c+2d=-7

-3+2d=-7

Randolph is creating rectangle WXYZ so that WX has an equation of y = 1 over 4x + 4. Segment XY must pass through the point (−2,
Sliva [168]

Answer:

The correct option is;

c.) y - 6 = -4(x - (-2))

Step-by-step explanation:

We note that the figure Randolph is creating is a rectangle, therefore, we have;

\overline{WX}\perp \overline{XY}, therefore, we have;

\overline{WX} = \dfrac{1}{4} x + 4

∴ Slope \overline{WX} = 1/4

\overline{XY} must pas through the point (-2, 6)

Given that \overline{WX}\perp \overline{XY}, we have;

Slope \ \overline{XY} = \dfrac{-1}{Slope \ \overline{WX}}

\dfrac{y - 6}{x - (-2)} = -1/\dfrac{1}{4}  = -4

y - 6 = -4(x - (-2))

Therefore, the correct option is c.) y - 6 = -4(x - (-2)).

Can someone pls help me on 4 and 5

Answer (4):

a=ub/k because

u=ak/b   (starting equation)

ub=ak    (multiply b to both sides)

a=ub/k   (divide both sides by k)

Answer (6)

x=g+c-y because

g=x-c+y  (starting equation)

x+y=g+c (add c to both sides)

x=g+c-y  (subtract y from both sides)
