Answer:

the number is 22

Step-by-step explanation:

let the number be x

-5(x-17) = -25

-5x + 85 = - 25

-5x = - 25 - 85

-5x = - 110

x = - 110 ÷ - 5

x = 22

Check answer

- 5 × ( 22) + 85

- 110 + 85

- 25

The slash indicates a fraction.

=============================================

Proof:

We'll need to consider 4 different cases.

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

Case (1): j > 0 and k > 0

If j > 0, then 3j > 0 and 3/j > 0

If k > 0, then 3k > 0 and 3/k > 0

The two points (3j, 3k) and (3/j, 3/k) are both in quadrant 1.

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

Case (2): j > 0 and k < 0

If j > 0, then 3j > 0 and 3/j > 0

If k < 0, then 3k < 0 and 3/k < 0

Points (3j, 3k) and (3/j, 3/k) are both in quadrant 4.

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

Case (3): j < 0 and k > 0

If j < 0, then 3j < 0 and 3/j < 0

If k > 0, then 3k > 0 and 3/k > 0

Points (3j, 3k) and (3/j, 3/k) are in quadrant 3.

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

Case (4): j < 0 and k < 0

If j < 0, then 3j < 0 and 3/j < 0

If k < 0, then 3k < 0 and 3/k < 0

Points (3j, 3k) and (3/j, 3/k) are in quadrant 4.

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

For nonzero integers j and k, we've shown that Points (3j, 3k) and (3/j, 3/k) are in the same quadrant. This concludes the proof.

Answer:

[tex]1.8*10^{-10}[/tex]

Step-by-step explanation:

To find the number in scientific notation you want to find how many times you have to move the decimal to get the decimal to be right after the first non-zero number. If you move to the left the exponent is positive and if you move it to the right the exponent is negative. The answer would be [tex]1.8*10^{-10}[/tex].

Answer:

The answer is 9

Step-by-step explanation:

set up the equation as 12^2 + b^2 = 15^2

solve the exponents and you get 144 + b^2 = 225

Then subtract 144 from both sides and get 81

After that just do the square root of 81 and you get 9

Answer:882

Step-by-step explanation:5 percent of 840 is 42 so 840 plus 42

Answer:

882

Step-by-step explanation:

Answer:

Yes.

Step-by-step explanation:

First, find the unit rate for 1 bookcase.

65 ÷ by 13 = 5 (unit rate)

Then, multiply the unit rate by the bookcases the carpenter wants to make.

6 · 5 = 30

Finally, subtract the shelves the carpenter wants to use by 30.

32 - 30 = 2 shelves.

Therefore, 32 shelves is enough to build 6 more bookcases. <3

Answer:

x = 7, arc DE = 198°

Step-by-step explanation:

Inscribed angles from the same arc are congruent.

∠ DCE and ∠ DWE are inscribed angles from the same arc DE , thus

12x + 15 = 3x + 78 ( subtract 3x from both sides )

9x + 15 = 78 ( subtract 15 from both sides )

9x = 63 ( divide both sides by 9 )

x = 7

Thus

∠ DCE = 12x + 15 = 12(7) + 15 = 84 + 15 = 99°

The inscribed angle DCE is half the measure of its intercepted arc, thus

arc DE = 2 × 99° = 198°

Answer:

32, consecutive interior angles are supplementary.

Step-by-step explanation:

We know that the two angles add up to 180, because consecutive interior angles are supplementary. So let's set up an equation equal to 180.

2x + 3x + 20 = 180

Now let's add like terms.

5x + 20 = 180

Now let's subtract 20 from both sides.

5x = 160

Now let's divide both sides by 5.

x = 32

Answer:

[tex]y=\frac{1}{10}x+6.5[/tex]

Step-by-step explanation:

We know that a perpendicular line is the slopes reciprocol, so we just flip it.

10/1 --> 1/10

y = 1/10x + b

Now we plug in the coordinates to solve for the y-int!

7 = (1/10)5 +b

7 = 1/2 + b

Subtract 1/2 on both sides!

6.5 = b

Reform equation!

[tex]y=\frac{1}{10}x+6.5[/tex]

Answer:

GH = 12, JH = 8, GJ = 10.6, your answer is the first choice

Step-by-step explanation:

Mid-segment theorem basically means it's like cut in half so just apply that logic to the entire thing:

DG = GF and IH = HF

DI length, 24, divided by two, because half, equals 12 so 12 = GH

JH is DF divided by two so basically 16/2 which is 8 which also equals DG

GJ = IH because like I said half half theory

Essentially, all the parallel lines are halves of each other.

GH = 12, JH = 8, GJ = 10.6, your answer is the first choice

Answer:

Option B. ( x + 2, y - 1 ) is the correct answer.

Step-by-step explanation:

First of all, we have to write the coordinates of vertices of both triangles and then compare the respective vertices to find the rule,

So the vertices are:

A(-4,2) , B(-3,4) and C(-1,1)

A'(-2,1), B'(-1,3) and C'(1,0)

By comparing respective vertices we can observe that

A(-4,2) => (x+2,y-1) => A'(-2,1)

B(-3,4) => (x+2,y-1) => B'(-1,3)

C(-1,1) => (x+2,y-1) => C'(1,0)

Hence,

Option B. ( x + 2, y - 1 ) is the correct answer.

Answer:

x=5

Step-by-step explanation:

Step 1: Flip the equation.

−2x−9=−19

Step 2: Add 9 to both sides.

−2x−9+9=−19+9

−2x=−10

Step 3: Divide both sides by -2.

Exact Form:

x = 9/17

Decimal Form:

x = 0.52941176…

Edit: "but what are the steps to get 9/17"

1. Move all terms containing x to the left side of the equation.

2. Divide each term by −17 and simplify.
