Elliot has a total of 26 books. He has 12 more fiction books than nonfiction books. Let x represent the number of fiction books and y represent the number of nonfiction books.

This system of equations models the number of books.

x + y = 26

x – y = 12

Elliot added the two equations and the result was 2x = 38.

Solve the equation. How many fiction books does Elliot have?

Answer:

The slope is -4/3.

Step-by-step explanation:

Slope = rise/run. Starting at (3, -1), you go up 4 units and over to the left 3 units to (0,3). Since it's a line of decay, the slope is negative.

Answer:

the slope should be -4/3

Step-by-step explanation:

you go down 4 and to the right 3 so I am pretty sure it is -4/3

Answer:

Option (C)

Step-by-step explanation:

From the picture attached,

Two lines are the parallel lines and one line is intersecting these lines at two distinct points.

m∠3 = ∠6 [Alternate interior angles]

Since, angles 2 and 7 are the vertically opposite angles,

m∠2 = m∠7 [Alternate exterior angles]

Therefore, angles ∠2 and ∠7 are the pair of alternate exterior angles.

Option (C) is the answer.

If you use 30 instead of 15, that means that  your sum will double

Step-by-step explanation: 30 is double 15

The value of 'x' is 115 degrees and this can be determined by using the sum of interior angles property of hexagon.

Given :

The following steps can be used in order to determine the value of x which is an interior angle of a hexagon:

Step 1 - According to the given data, the given polygon has 6 sides means that it is a hexagon with interior angles 118°, 127°, 111°, 123°, 126°, and x°.

Step 2 - The sum of interior angles of a hexagon is 720 degrees.

Step 3 - So, the values of 'x' can be calculated by using the below expression:

118 + 127 + 111 + 123 + 126 + x = 720

Step 4 - Simplify the above expression.

605 + x = 720

x = 720 - 605

x = 115 degrees

Answer:

the value of the number in the thousandths place is 9

Step-by-step explanation:

No calculator!

The given equations are as follows

[tex]\begin{aligned} A.&&\dfrac x4+1&=-3 \\\\ B.&&x+4&=-12 \end{aligned}[/tex]

(1) First, multiply both sides of equation A by 4, we have

[tex]4\times\left(\frac{x}{4} +1\right)=4\times(-3)[/tex]

Then, rewrite the left-hand side of the above equation by using the distributive property, we have

[tex]4\times\frac{x}{4}+4\times1=4(-3)[/tex]

[tex]\Rightarrow x+4=-12[/tex]

This is the required equation B.

In this way, first use choice D: Multiply both sides by the same non-zero constant, i.e 4.

Then, apply choice A to solve the equation, i.e using the distributive property to solve the left-hand side of the equation.

(2) In the previous answer, equation B has been derived from equation A, hence, both the equations are equivalent.

As both the equations are the same, so both will have the same solution.

Yes, they have the same solution.

Step-by-step explanation:

Based on the HL congruence rule, the value of x, is calculated as:

x = 2.

Both triangles that share the same side and have corresponding angle 90 degrees and a pair of corresponding congruent hypotenuse are congruent  to each other based on the HL congruence theorem.

This means that:

17x - 3 = 9x + 13

Solve for the value of x:

17x - 9x = 3 + 13

8x = 16

Divide both sides by 8:

8x/8 = 16/8

x = 2

The value of x is: 2.

Answer:

X Intercept: (-2, 0)

Y Intercept: (0, 7)

Explanation:

Plug y = 0 into the equation and solve the resulting equation 7x = −14 for x. Plug x = 0 into the equation and solve the resulting equation −2y = −14 for y.

Answer:

(- 2, 0 ) and (0, 7 )

Step-by-step explanation:

To find the x- intercept let y = 0 in the equation and solve for x

7x - 2(0) = - 14, that is

7x = - 14 ( divide both sides by 7 )

x = - 2 ⇒ (- 2, 0 ) is the x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

7(0) - 2y = - 14, that is

- 2y = - 14 ( divide both sides by - 2 )

y = 7 ⇒ (0, 7 ) is the y- intercept

Answer:

1 (square root of 72)

Step-by-step explanation:

Ok. You can solve this using the pythagorean thereom. This is because AB is the hypotenuse of a right triangle. Therefore, you can solve this problem by using the square of both sides to find the length of the hypotenuse. 6^2+6^2=c^2.

36+36=72

[tex]\sqrt 72[/tex]=8.5

8.5 is about what the line looks to be just by eyeing it, and it fits in with the theroem used, therefore I'd say it is #1. Hope that helps.

Answer:

67

Explanation:

the angle labeled 10 which is =113 and the angle labeled 11 are co interior angles.

co interior angles add upto 180 therefore to get the value of the angle labeled 11 you subtract 113 from 180 which gives you 67

the angle labeled 11 which is =67 and the angle labeled 8 are alternate angles. Alternate angles are equal therefore the value of the angle labeled 8 which you've been asked to give is 67

y = - 0.5 | x - 5 | + 2

Step-by-step explanation:

g(x) = |x|

[tex]1^{st}[/tex] step - shifts right 5 units: g(x + 5) = | x - 5 |

[tex]2^{nd}[/tex] step - shifts up 2 units: g(x + 5) + 2 = | x - 5 | + 2

[tex]3^{rd}[/tex] step - reflected: - g(x + 5) + 2 = - | x - 5 | + 2

[tex]4^{th}[/tex] step - stretched by 0.5: y = - 0.5 | x - 5 | + 2

y = - 0.5 | x - 5 | + 2
