-2(4x+4)-3x-2=34 what's the answer
Julli [10]

Answer:

x = -4

Step-by-step explanation:

Given: -2(4x + 4) - 3x - 2 = 34

To solve this equation, we have to isolate the variable. (Get x by itself).

We'll follow the PEMDAS rule as far as parentheses.

So, -2(4x + 4) - 3x - 2 = 34

= -8x - 8 - 3x - 2 = 34

Now, we have to get x by itself. To do this, we'll move the numbers without variables to the other side.

Hence:

-8x - 8 - 3x - 2 = 34

     +8        +2       +8  +2

-8x - 3x = 34 + 8 + 2

Now, we'll simplify.

-11x = 44

Lastly, to rid the negative eleven from the x, we have to divide negative eleven by the rest of the equation.

-11x = 44

-------------

-11

x = -4

What is the vertex of the graph y = x^2 + 6x - 5 ?
Dafna11 [192]
Given:  <span>y = x^2 + 6x - 5.  Then a = 1, b = 6 and c = -5.

The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.

Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:

y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14

Then the vertex is (-3, -14).</span>

Andrea bought tacos from a food truck and left a 2 5 % 25%25, percent tip of $ 2 . 0 0 $2.00dollar sign, 2, point, 00. What was
Bingel [31]

Let us say the original price of taco before tip was x dollars.

Percentage of tip given =25 %

Amount of tip given = $2

Now we can say that 25 % of total amount = 2 dollars.

Making an equation,

0.25x =2

Now we have to solve for x, so dividing both sides by 0.25,

x= 8

Answer : The original price of tacos before tip was $8.
