Answer:

Step-by-step explanation:

2x - 12 + 3x - 17 = 26

5x - 29 = 26

5x = 55

x = 11

2(11) - 12 = 22 - 12 = 10 EF

3(11) - 17 = 33 - 17 = 16 FG

How to simplify an expression with a negative exponent

svetlana [45]

Answer:

Step-by-step explanation:

An negative exponent seems hard, but it really isn't!

Let's say you have $2^{-3}$

All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .

$\frac{1}{2^{3} }$

$2^{3}$ simplifies into 8. So, the result is

$\frac{1}{8}$

Hope this helps! Please mark as brainliest, thanks!

Solve each system of equations using matrices.<br> -2x = -6y + 8<br> 2y = x + 1

Elden [556K]

Answer: 1.) x - 2y = 4 , add 2y to both sides. ---> answer is, X = 2y + 4

2.) 2x - 6y = 8, Add 6y to both sides, then divide both sides by 2. --> answer is, X = 3y + 4

Free fall reaches 216km per hour. What is rate in meters per second.? How many meters fall during 20 seconds free fall?

lakkis [162]

Given,

Rate of free fall = 216 km/h

Solution,

km/h to m/s is converted as follows :

$216\ \dfrac{km}{h}=216\times \dfrac{1000\ m}{3600\ s}\\\\=60\ m/s$

So, the rate of fall is 60 m/s.

If t = 20 s

Assume, initial velocity = 0

It will move under the action of gravity.

Using equation of motion,

$h=ut+\dfrac{1}{2}gt^2\\\\h=0+\dfrac{1}{2}\times 10\times 20^2\\\\h=2000\ m$

Hence, this is all for the solution.
