Answer:

(x, y) = (3, -7)

Step-by-step explanation:

\left \{ {{x - 3y = 24} \atop {5x + 3y = -6}} \right.

\left \{ {{x-3y=24} \atop {3y=-6-5x}} \right.

x-(-6-5x)=24

x=3

3y=-6-5(3)

y=-7

(x,y)=(3,-7)

CHECKING IF ANSWER IS CORRECT:

\left \{ {{3-3(-7)=24} \atop {5(3)+3(-7)=-6}} \right.\\\left \{ {{24=24} \atop {-6=-6}} \right.  \\(x,y)=(3,-7)

There is your answer with steps :)

Ronch [10]

Answer:

793.25 mi/hr

Step-by-step explanation:

Given that:

The radius of the earth is = 3030 miles

The angular velocity = \dfrac{\pi}{12} rads

If a jet flies due west with the same angular velocity relative to the ground at the equinox;

We are  to determine the How fast in miles per hour would the jet have to travel west at the 40th parallel for this to happen.

NOW;

Distance s is expressed by the relation

s = rθ

s = 3030(\frac{\pi}{12} )

s = 793.25

The speed which depicts how fast in miles per hour the jet would have traveled is :

speed (v) = \frac{s}{t}

v = \frac{793.25}{1}

v = 793.25 mi/hr

Hence, the jet would have traveled 793.25 mi/hr due west at the  40th parallel for this to happen.

One line passes through the points (-7,5)
Studentka2010 [4]

Answer:

1. (-7, 5 ) and (-1, 3)

(3-5)/(-1+7)= -2/6 = -1/3

y - 5 = (-1/3)(x + 7)

y - 5 = (-1/3)x - 7/3

y - 15/3= (-1/3)x - 7/3

y = (-1/3)x + 8/3

2. (-1-3)/(3-0)= -4/3

y + 3 = (-4/3)(x + 1)

y + 3 = (-4/3)x - 4/3

y + 9/3 = (-4/3)x - 4/3

y = (-4/3)x + 5/3

the answer is neither

Tamika wants to double the volume of a square pyramid. What should she do?
ella [17]
To efficiently double the volume of a square pyramid, you need to double the height of the pyramid. 

<span>V = (1/3)Ah where A is the area of the base. If you double the height and leave A unchanged, the volume will also be doubled (replace h with 2h in the formula).</span>
