can anyone help me with this one

Step-by-step explanation:

(y2-y1)/(x2-x1)=(y-y1)/(x-x1)

(-21-15)/(-2-4)=( y-15)/(x-4)

6(x-4)=y-15

6x-y-9=0

Answer:

113

Step-by-step explanation:

The given shape has 6 angles so it's a hexagon and the sum of interior angles in a hexagon is = 720

To find the the value of x we need to add all given values up and subtract it from 720:

88 + 142 + 105 + 136 + 136 + x = 720

607 + x = 720 subtract 607 from both sides

x = 113

Answer:

Step-by-step explanation:

One way to answer this problem is to notice as x goes up 1, y will go up 2. The relationship is linear. No exponential function is going to do that. The jump will not be so easily described.

So what's the answer?

The exact description is D. It is just what I wrote in more general terms.

Answer:

$40.95

Step-by-step explanation:

Original price = $65.00

If the jacket is on sale for 40% off, then it is now 60% of the original price.

60% = 60/100 = 0.6

⇒ 60% of $65.00 = 0.6 × 65

                              = $39

If we have to pay 5% sales tax, then this means that the final price will be 105% of the sale price.

105% = 105/100 = 1.05

⇒ 105% of $39 = 1.05 × 39

                         = $40.95

Discount:-

[tex]\\ \rm\rightarrowtail 0.40(65)=26\$[/tex]

Now

So

Sales tax is 5%

Total price=39+0.05(39)=40.95$

Answer: $2.10

Step-by-step explanation: 22-15.70= 6.3

This means you spent $6.30 on pretzels. Divide 6.30 by 3 to find out how much each pretzel costs. You would get 2.1 (which is written as $2.10 in money).

Answer:

5x² + 5x + 9

Step-by-step explanation:

(3x + 4) + ((5x² - 1) + (2x + 6))

Remove parenthesis

3x + 4 + 5x² - 1 + 2x + 6

Group like terms

5x² + 3x + 2x + 4 - 1 + 6

Subtract 1 from 4

5x² + 3x + 2x + 3 + 6

Add 3 and 6

5x² + 3x + 2x + 9

Combine like terms

5x² + 5x + 9

Answer: 5x² + 5x + 9

Answer:. Then either A = C and B = D, or A = D and B = C.

Step-by-step explanation:

The 3 equivalent pairs are:

Remember that two numbers A and B are equivalent if:

A = B

The first pair given is:

-0.5 and (-1/2).

We know that 1/2 = 0.5, then (-1/2) = -0.5

So we conclude that

-0.5 and (-1/2) are equivalent.

Another equivalent pair is:

11/20 and 0.55

To check this, you can just solve the fraction in your calculator, you will see that:

11/20 = 0.55

Then 11/20 and 0.55 are equivalent.

The final equivalent pair is:

-1/50 and -0.02

Because:

-(1/50) = -(0.02) = -0.02

Then -1/50 and -0.02 are equivalent.

Answer:

a. y equals one third times x plus 10

= y = 1/3(x) + 10

Step-by-step explanation:

Let us represent:

Let the original final plan = x

Let the current flight plan = y

The initial time of departure = 4.00pm

Her flight was then delayed for 10 minutes

We are told in the question that:

The current flight plan allows her arrive at her destination three times faster.

This means y= (1/3)x

y = x/3

Hence the equation generated =

y = x/3 +10

y = 1/3(x) + 10

Answer:

y = 1/3x + 10

Step-by-step explanation:

Step-by-step explanation:

Since you added 12 to the x coordinate and subtracted 7 from the y coordinate, to undo that translation, you need to subtract 12 from the x coordinate of the image and add 7 to the y coordinate of the image.

This gives you that C=(-2-12, 1+7)=(-14, 8)

Answer:

d - 11*16

Step-by-step explanation:

Algebraic Expressions

We use algebraic expressions to model real-world situations and we must pay close attention to the writing of the problem to do it properly and accurately.

Let's build the expression in small steps:

11 times the quantity 16 = 11*16

That amount less than a number d. It suggests a subtraction:

d - 11*16

Answer:

Step-by-step explanation:

m∠ACB = m∠CBD = 90° ⇒ m∠CAB = 90° - 50° = 40° = m∠ABD ( Alternate interior angles )

m∠CBD = 90°

m∠CDB = 50 °

Check the picture below, notice the tickmarks, both sides are equal and they make twin angles on the "base" side of the isosceles triangle.

Answer:

2,4,1,3

Step-by-step explanation:

So, I labeled each one, 1,2,3, and 4 respectively.

1, when expanded is 0.000005

2 is equal to -0.009

3 is simple 0.00007

and 4 is -0.0000002

Obviously the one of the negative numbers is the smallest. The bigger number with the negative sign is more negative because it is farther away from one on the number line. Therefore 2 is the smallest. That makes 4 the second smallest. 3 is larger than 1 because there are less zeros to the first non-zero digit. That places the order from least to greatest as:

2,4,1,3

Answer:

  False

Step-by-step explanation:

The number of molecules in a mole of any substance is Avogadro's number, 6.022×10^23. The number of moles of a substance is the  mass of it divided by the mass per mole. Here, we expect the number of molecules to be about ...

  (6.022×10^23 molecules/mole) × (50 g)/(87.91 g/mole)

  ≈ 3.425×10^23 molecules

The suggested number is approximately 12% low, too far off to be considered "about" correct. The offered statement is FALSE.

Answer: 1.6 km

Step-by-step explanation:

If they can replace 400 meters in 5 days, that means they can replace 80 meters in 1 day, (400/5). So in 20 days, they will do 20x80 = 1600 meters. Since 1000 meters make one km, 1600/1000 = 1.6 km in 20 days

Answer:

40 points

Step-by-step explanation:

The score for the first four rounds of the game is 13, 17, 19, and 21 points.

Let [tex]S_5[/tex] and [tex]S_6[/tex] be the scores of the fifth and sixth games respectively in order to achieve an average score of 20 points per round for all six rounds.

[tex]\text{Average score} = \frac{\text{Sum of the scores of all the rounds}}{\text{Total number of the rounds}}[/tex]

[tex]\Rightarrow 20=\frac{13+17+19+21+S_5+S_6}{6}[/tex]

[tex]\Rightarrow 20\times6=80+S_5+S_6[/tex]

[tex]\Rightarrow S_5+S_6=120-80=40.[/tex]

Hence, the combined score of the fifth and sixth rounds are 40 points.
