<u>Answer:</u>

x=-9

<u>Step-by-step explanation:</u>

STEP 1: Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

<em />9(x-5)-14x=-7(x+9)

STEP 2: Simplify 9(x−5)−14x.

-5x-45=-7(x+9)

STEP 3: Simplify −7(x+9).

-5x-45=-7x-63

STEP 4: Move all terms containing x to the left side of the equation.

2x-45=-63

STEP 5: Move all terms not containing x to the right side of the equation.

2x=-18

STEP 6: Divide each term by 2 and simplify.

x=-9

General Formulas and Concepts:

<u>Algebra I</u>

  • Reading a coordinate plane
  • Range is the set of y-values that are outputted by function f(x)
  • Interval Notation: [Brackets] denote inclusion, (Parenthesis) denote exclusion

Step-by-step explanation:

According to the graph, our y-values span from -7 to 8. Since both are closed dot, they are included in the range:

the circumference of the great circle of a sphere is 12 pi inches. Which of the following expressions can be used to approximate
andriy [413]
It would be A because with volume you would have your 12 to the 3rd power then multiply it by pie which is 3.14 then for sphere you would then multiply what ever you got after multiplying 12 to the 3rd power then by 3.14 to the 4/3

The system of equations below represents the measures of 2 angles created by the diagonal of a rectangle: x + y = 90 y =1/5 What
madreJ [45]

Answer:

The larger of the two angles is x, which is 75. y is the smaller angle at 15.

Step-by-step explanation:

In order to find these, we can use our solved value for y in the second equation to plug into the first equation. This method is called substitution.

x + y = 90

x + (1/5x) = 90

1.2x = 90

x = 75

Now we can plug that value into either equation to find y

y = 1/5x

y = 1/5(75)

y = 15
