Solve the following inequality: 2x^2 + x - 1/x^2-x<1​

9514 1404 393

Answer:

  x = 8.5

Step-by-step explanation:

The given angles are complementary, so ...

  (4x -8) +(6x +13) = 90

  10x +5 = 90 . . . collect terms

  10x = 85 . . . subtract 5

  x = 8.5 . . . . divide by 10

3x = 8

Step-by-step explanation:

combine all the #x's on the left side

Answer: x= -8

Step-by-step explanation:

-11x=8-2x-8x

-11x=8-10x

-11x+10x=8-10x+10x

-x=8

-x/-1 = 8/-1

Answer:

EG=HJ

Step-by-step explanation:

The SSS postulate says that if all of the sides lengths of the triangle are given, then the second triangle will be congruent. We are given the side lengths of two sides so that means that we only need the side lengths of the last side.

Answer:

i can explain it to you.

Step-by-step explanation:

SO first you're going to label the graph with the munbers. If you don't know how they go just search one up because they all look the same.

Then you're going to place them on the coordinates that they correspond to. (x,y)

Then for the rotation you're going to move it 90* clockwise which would be right but in the shape of a circle. But you have to connect the dots.

Basically you're just laying it down on its side to the right.

Hope this helps. :)

Answer:

21 + 22 + 23 +24 = 90

Step-by-step explanation:

Let's represent this with x:

x+x1+x+2+x+3 = 90

Group the x's together

4x+6 = 90

subtract 6 on both sides

4x=84

x=84/4

x= 21

Answer:

it would 35 feet long 100x0.35

The length of the movie theater will be 35 feet.

In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations. For example, we can write the expressions as -

2x + 3y + 5

3y + 5

5 + 6

Given is that the length of Yvette's cell phone screen is 0.35 feet. A movie theater screen is about 100 times longer than Yvette's cell phone screen.

Scale factor is defined as the ratio of final dimensions to the initial dimensions of the given image.

Mathematically, we can write -

{K} = final dimensions/initial dimensions

In the question given, the scale factor is -{K} = 100.

Assume the length of the movie theater to be {x}. So, we can write -

{x} = 0.35 x 100

{x} = 35/100 x 100

{x} = 35 feet

Therefore, the length of the movie theater will be 35 feet.

Step-by-step explanation:1

1/2 years which is 1 year and 5 months.

Explanation:

The formula for simple interest is

You can either substitute the given values first and the solve for

T, or you can transpose the formula to have

T as the subject.

T=100xSIPR

T=100 x 637.50

T=100×637.502500×17

T=1.5

As time is always in years, this means it was for

112 years which is 1 year and 5

Answer:55

Step-by-step explanation:

Answer:

A) y - 11 = -6(x - 0)

C) y + 1 = -6(x - 2)

Step-by-step explanation:

Plug in the corresponding x- and y- values in the table into the equations given in the answer choices.

I am going to use (1, 5) from the table.

-6 DOES equal 6, so this equation could represent the points in the table.

4 does NOT equal 36, so this equation could not represent the points in the table.

6 DOES equal 6, so this equation could represent the points in the table.

-2 does NOT equal 12, so this equation could not represent the points in the table.

The only two equations that could represent the points in the table are answer choices A) y - 11 = -6(x - 0) and C) y + 1 = -6(x - 2).

Answer:

45 rows will need to be built to hold 1350 cars. (for 30 spaces a row)

19 fewer rows are needed if the rows fit 50 cars (for the 50 spaces a row)

Step-by-step explanation:

for the first question divide 1350 by 30 and the second divide 1350 by 50, good luck!

Answer:

m perpendicular = −3 / 2

Step-by-step explanation:

y = m x+b

where m represents the slope and b, the y-intercept.

−3 y = −2 x + 5

divide all terms by - 3

−3 y − 3 = − 2 − 3 x + 5 − 3

y = 23 x − 53

in slope-intercept form

slope = m = 23

The slope of a perpendicular line is the

negative reciprocal of m

Answer:

∠H = 122°

Step-by-step explanation:

This is a 5-sided polygon. That means the sum of all the angles must equal 540°.

∠H + 107° + 97° + 130° + 84° = 540°

∠H = 540° - (107° + 97° + 130° + 84°)

∠H = 540° - 418°

∠H = 122°
