Answer:

The answer is false.

Step-by-step explanation:

It is always helpful to rewrite an equation in standard form as a first step in solving it. This is false.

The elimination technique works for the addition and subtraction of equations. For solving linear equations given in slope intercept form, we simply equate the 'y' and solve for 'x'. Then finding y is easy.

A rocket is launched from atop a 75 foot cliff with an initial vertical velocity of 107 feet per second. The height of the rocke
satela [25.4K]

The distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds

<u>Explanation:</u>

Given:

Height, h = 75 foot

Initial velocity, u = 107 foot/sec

Equation:

h = -16t² + 107t + 75

Substituting the equation:

75 = -16t² + 107t + 75

0 = -16t² + 107t

16t² = 107t

t = 6.6875s

We know:

Distance = speed X time

d = 107 f/s X 6.6875s

d = 715.56 foot

Therefore, the distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds

In a sale, all normal prices are reduced by 15%
sladkih [1.3K]

Answer:

The normal price of mixer is $150.

Step-by-step explanation:

Given that:

Normal prices are reduced by 15% in sale.

The normal price of mixer is reduced by $22.50

It means that it is the amount of discount.

Let,

x be the normal price of the mixer.

15% of x = 22.50

\frac{15}{100}x=22.50\\0.15x=22.50

Dividing both sides by 0.15

\frac{0.15x}{0.15}=\frac{22.50}{0.15}\\x=150

Hence,

The normal price of mixer is $150.
