Solve. –355 + 355 = 0 355 710 –710

Verdich [7]

Hey there,

–355 + 355 =

Your correct answer is 0.

So,for example, -1+1+0.

The answer would be 0 because it used to be a negative number, but once there is exact number (but positive) as the same number as before, they would get you 0.

Hope this helps.

How many solutions for x does the following equation have? 2(x + 4) − 1 = 2x + 7

4vir4ik [10]

Answer:

The equation has infinity solutions

Step-by-step explanation:

we have

$2(x+4)-1=2x+7$

Applying distributive property left side

$2x+8-1=2x+7$

Combine like terms

$2x+7=2x+7$

The linear equation of the left side is equal to the linear equation of the right side

Both lines are identical

therefore

Is a consistent dependent system

The equation has infinity solutions

Calculate the average rate of change for the function

mezya [45]

$slope = m = \cfrac{rise}{run} \implies \cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby \begin{array}{llll} average~rate\\ of~change \end{array}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ f(x)= 2(x-2)^2+1\qquad \begin{cases} x_1=-2\\ x_2=4 \end{cases}\implies \cfrac{f(4)-f(-2)}{4-(-2)} \\\\\\ \cfrac{[2(4-2)^2+1]~~ - ~~[2(-2-2)^2+1]}{4+2}\implies \cfrac{[9]~~ - ~~[33]}{6}\implies \cfrac{-24}{6}\implies -4$

The relationship between two numbers is described below, where x represents the first number and y represents the second number.

Daniel [21]

X=y+16

4y-1=7

Solve on both sides

4y=8

Y=8/2

Y=4

X= (4)+16

X=20
