Answer:

see attached

Step-by-step explanation:

y-2=-2(x+4)

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

y -2 = -2x - 8

y = -2x - 8 + 2

y = -2x - 6

When x = 0, y = -6. Hence (0,-6) is a point on the line

when y = 0, x = -3. Hence (-3,0) is a point on the line.

Plot these 2 points and connect with a line (see attached)

mel-nik [20]

Answer:

It is congruent to Angle A P C

Step-by-step explanation:

we know that

Vertical angles are the angles opposite each other when two lines cross. They are always congruent.

In this problem we have that

$m\angle APC=m\angle BPC$ -----> by vertical angles

see the attached figure to better understand the problem

therefore

It is congruent to Angle A P C

-3x + 2y = 21 -4x + y = 23

Nady [450]

Answer:

2y = 3x + 21

y = 1.5x + 10.5

plug in, in the second equation

- 4x + (1.5x + 10.5) = 23

-4x + 1.5x + 10.5 = 23

-2.5x + 10.5 = 23

-2.5x = 12.5

x = 12.5/-2.5 = -5

y = 1.5 (-5) + 10.5 = 3

x = -5

y = 3

p varies directly as q and inversely as r. One set of values is p = 5, q = 1, and r = 2. Find p when q = 10 and r = 50.

Alexeev081 [22]

P = kq/r

5 = k*1/2
k = 2*5 = 10

p = 5*10/50 = 1
P is 1.

Hope it helps!

MakcuM [25]

Answer:

5 days.

Step-by-step explanation:

The food will last her 5 days.
$3\frac{1}{2}-\frac{5}{8}-\frac{5}{8}-\frac{5}{8}-\frac{5}{8}-\frac{5}{8}$
$=1\frac{5}{8}-\frac{5}{8}-\frac{5}{8}$
$=1-\frac{5}{8}$ $=\frac{3}{8}$
