Answer: 5x + 16

Step-by-step explanation: distribute, add the numbers, and combine like terms.

Natalija [7]3 years ago

Answer:

x = -3.2

Step-by-step explanation:

First, solve parenthesis:

2(x+6)+3x+4= 0  (Given)

2x + 12 + 3x + 4 = 0   (distributive property of equality)

Then, you comibine like terms:

2x + 12 + 3x + 4 = 0

5x + 16 = 0 (Combining like terms)        

And then, move the variables to the left and constants to the right:

5x + 16 = 0

5x = -16 (Subtraction property of equality) You subtract 16 from both side, since the variable is on the right already you leave it that way.

Finally, you divide both sides to get  the answer ( solve for X):

5x = -16

x = -3.2 (division property of equality)

There is your answer!

Hope this helps!

A mountain in boone county is eroding and losing elevation at a rate of 5% every millennium. if the current elevation is 1,710 m
aliina [53]

Answer: 1,393 meters tall

Step-by-step explanation:

Plug in 1710 meters for the initial amount, 0.05 for the rate of decrease, and 4 millennia for the time elapsed.

y

= a(1–r)t

y

= 1,710(1–0.05)4 Plug in values

y

= 1,710(0.95)4 Subtract

y

= 1,710(0.81450…) Simplify

y

= 1,392.80568… Multiply

Round to the nearest whole number.

1,392.80568… → 1,393

To the nearest whole number, the mountain will be 1,393 meters tall.

Do you know how to find rate of change? X&Y intercepts? Zeros?
Rzqust [24]

#Rate of change

Rate of change is slope

If two points be (x1,y-1) and (X2,Y2) then

  • Slope=m=y_2-y_1/x_2-x_1

If a line be ax+by+c=0

  • m=-a/b

#X and y inetercept

If a equation given y=mx+b

  • To find x intercept put y=0
  • To find y inetercept put x=0

#Zeros

To find the zeros spot out the x inetercepts

The x values of the x intercepts are the zeros
