Answer:

B. (-2,3)

Step-by-step explanation:

-3x+5y = 21

x=2y-8

Substitution

-3(2y-8)+5y =21

-6y+24+5y=21

-y+24=21

-y=-3

y=3

Plug-in other equation

2*3-8=x

6-8=x

x=-2

What is the surface area of the square pyramid represented by the net? Enter your answer in the box. m² An unfolded square base
OlgaM077 [116]

Answer:

The surface area of the square pyramid is 144\ m^{2}

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to

SA=B+Ph/2

where

B is the area of the base

P is the perimeter of the base

h is the height of the pyramid

<u>Find the area of the base B</u>

B=6^{2}=36\ m^{2}

<u>Find the perimeter of the base P</u>

P=4*6=24\ m

The height is h=9\ m

substitute the values

SA=36+24*9/2=144\ m^{2}

Each day of overtime you work, you earn an additional $50 more than your regular pay of $100 a day.
GaryK [48]

The answer should be $650 because, $100 a day for five days is $500. Then the overtimes for three days would equal up to $150 in overtime. $500 + $150 = $650

Rewrite the equation as y-2=-2/3(x-(-1)) to identify a point on the graph
Anvisha [2.4K]

Answer:

  point (-1, 2)

Step-by-step explanation:

Your equation is shown here in point-slope form, so a point on the graph can be read from the given equation. (No further rewrite is necesary.)

The point-slope form is ...

  y -k = m(x -h)

Comparing this to your given equation ...

  y -2 = (-2/3)(x -(-1))

we see that ...

  k = 2, m = -2/3, h = -1

The point on the graph is (h, k) = (-1, 2).
