What are the two solutions of 2x2 = -x2 – 5x – 1?

A: the y-coordinates of the intersection points of the graphs of y=2x^2 and y= -x^2-5x-1

B: the x-coordinates of the x-intercepts of the graphs of y=2x^2 and y= -x^2-5x-1

C: the x-coordinates of the intersection points of the graphs of y=2x^2 and y= -x^2-5x-1

D: the y-coordinates if the y-intercepts of the graphs of y=2x^2 and y= -x^2-5x-1

An expression that has the same value could be..

12x12, 3x48, and 9x16

Answer:

1) 12 x 12

2) 72 x 2

Step-by-step explanation:

This is the answer because:

1) 12^2 equals 144

2) 12 x 12 equals to 144, as well as 72 x 2 because this expression also equals to 144

Answer:

[tex] - 3x - 7(x + 4) \\ = - 3x - 7x - 28 \\ = - 10x - 28[/tex]

hope it helped you:)

Answer:

[tex]-10x-28[/tex]

Step-by-step explanation:

[tex]-3x-7(x+4)[/tex]

Expand by using distributive law: [tex]a(b+c)=ab+ac[/tex]

Therefore,

[tex]-3x-7*x+\left(-7\right)\cdot \:4[/tex]

[tex]-3x-7x-7\cdot \:4[/tex]

[tex]-3x-7x-28[/tex]

Add the x:

[tex]-10x-28[/tex]

Answer: 7.4

Step-by-step explanation:

3x + 13 = 19

3x = 6

x = 2

Now substitute value of 'x' in the second equation:

2(2) + 1.2(2) + 1

= 4 + 2.4 + 1

= 5 + 2.4

= 7.4

Answer:

7.4

Step-by-step explanation:

The value of X is 2, so 3*2=6   6+13=19

So the second equation is 2*2=4  4+1.2*2=6.4  6.4+1=7.4

Answer:

Plane SPT and Plane SPV

Step-by-step explanation:

A plane is defined by the set of three points lying on the same (two dimensional) surface.

A plane 'R' has been given in the picture.

Points lying on this plane or surface are S, P, T and V.

Therefore, possible names may be,

SPT, STV, SPV, PTV

From the given options names of the plane R will be,  

Plane SPT and Plane SPV,  

Answer:

A = [tex]\frac{5}{6}[/tex]

Step-by-step explanation:

From the number line attached in the figure,

Number of small parts from number 0 to 1 on the given number line = 6

A is the point which lies at 5th part from 0.

Each small part represents the fraction = [tex]\frac{1}{6}[/tex]

Therefore, A represents the fraction = [tex]5\times \frac{1}{6}[/tex]

                                                             = [tex]\frac{5}{6}[/tex]

So A = [tex]\frac{5}{6}[/tex] will be the answer.

Answer:

Length of new rectangle = (x + 7) inches

Width of new rectangle = (x + 4) inches

Step-by-step explanation:

A rectangle is a quadrilateral that has opposite sides to be parallel and equal. While a square has all its sides to be equal.

Given that: the square has unknown side length x inches.

Increasing one of its length by 4 inches = (x + 4) inches

Increasing the other by 7 inches = (x + 7) inches.

The new lengths results to a rectangle with length (x + 7) inches, and a width of (x + 4) inches.

the label diagram to represent the new rectangle is shown in the diagram attached to this answer.

Answer:

28

Step-by-step explanation:

first, do 8-6 because that's in its own brackets, then do 5+2 and multiply it by the answer to 8-6. finally, multiply that by 2.

8-6=2

5+2=7

2×7=14

14×2=28

28

Answer:

18

Step-by-step explanation:

First, solve everything inside the parenthesis

1) 8-6=2

2) 5+2*2=9

Next, multiply 9 and 2

3) 9*2=18

Answer:

a > −6

Step-by-step explanation:

Step 1: Subtract a from both sides.

2a + 6 − a > a − a

a + 6 > 0

Step 2: Subtract 6 from both sides.

a + 6 − 6 > 0 − 6

a > −6

Answer:

Step-by-step explanation:

9x-4= 3x-28

We simplify the equation to the form, which is simple to understand  

9x-4=3x-28

We move all terms containing x to the left and all other terms to the right.  

+9x-3x=-28+4

We simplify left and right side of the equation.  

+6x=-24

We divide both sides of the equation by 6 to get x.  

x=-4
