Solve the system of equations algebraically.<br><br> {Y=(x-2)^2+2<br> {Y+4=3x
nikdorinn [45]

Answer:

(5, 11) and (2, 2)

Step-by-step explanation:

y = (x-2)² + 2

y + 4 = 3x

(x-2)² + 2 + 4 = 3x

x² - 4x + 4 + 6 = 3x

x² - 7x + 10 = 0

(x - 5)(x - 2) = 0

x - 5 = 0, x = 5

x - 2 = 0, x = 2

y = (5-2)² + 2 = 11

(5, 11)

y = (2-2)² + 2 = 2

(2, 2)

A yellow hot-air balloon is 100 feet off the ground and rising at rate of 8 feet per second.An orange hot-air balloon is 160 fee
Serhud [2]

ANSWER

Find out the how long will the Yellow balloon be higher than the orange balloon.

To proof

Now  the diagram is given below

As given

A yellow hot-air balloon is 100 feet off the ground and rising at rate of 8 feet per second.

i.e height of the yellow baloon off the ground  = 100 feet

rising at rate = 8 feet per second.

.An orange hot-air balloon is 160 feet off the ground and rising at a rate of 5 feet per second.

i.e height of the orange baloon off the ground  = 160 feet

rising at rate = 5feet per second.

Formula

Relative\ velocity = \frac{Relative\ Distance}{Relative\ time}

Relative velocity =  rising rate of yellow balloon -   rising rate of orange balloon

= 8 -5

= 3 feet per second

Relative distance =  height of the yellow baloon off the ground -  height of the orange baloon off the ground

= 160 -100

= 60 feet

put in the formula

= \frac{60}{3}

= 20 second

after  20 second Yellow balloon will be higher than the orange balloon.

Hence proved

Write an equation for the line parallel to y = -7x + 15 that passes through the point P(9,-6).
Elan Coil [88]

Answer:

y = -7x + 57

Step-by-step explanation:

If the line is parallel, it will have the same slope. So, this line will also have a slope of -7.

Use y = mx + b, plug in the slope and given point, and solve for b:

y = mx + b

-6 = -7(9) + b

-6 = -63 + b

57 = b

Plug in the slope and y intercept into y = mx + b:

y = mx + b

y = -7x + 57

So, the equation is y = -7x + 57
