What is the difference? Negative 6 minus (11) –17

Answer:

Step-by-step explanation:

Using the parallelogram theorem

3x-8 = 10x+13

-7x = 21

x = -3

Substitute

3(-3) - 8

-17

10(-3) + 13

-17

Answer:

4,000,000,000,000

Step-by-step explanation:

Make it look like this first:

[tex]\frac{6*10^8}{1.5*10^-4}[/tex]

You get:

[tex]4*10^{12}[/tex]

Which is 4,000,000,000,000

Answer:

So first lets find g(-1)

so we plug in the answers:

-2 * -1 ^2 -4

-2*1-4 = -2-4 =

-6

Now lets solve for f(-2)

-2^2-3

4-3=1

-6+1 = 5

3*5 = 15

Im getting answer of 15 but it shows -15 or something, so I dont know if I got it wrong or if its like a dash then the answer.

Answer: 140 km

Step-by-step explanation:

240 km in 3 hours

1 3/4 hours = (1 3/4 / 3) x 240

= (7/4 / 3) x 240

= 7/12 x 240

= 7 x 20 = 140

Answer:

D.(-1,-5) and (5,7)

Step-by-step explanation:

I used a graphing tool to graph the two equations together. When graphed, the equations intercept (5,7) and (-1,-5). Therefore, they are the solutions to the system.

Option D should be the correct answer.

Answer:

I believe that the answer is

Galina was correct when she said: there are 2 possible outcomes.

Elroy was correct when he said: multiply the 10 outcomes

Step-by-step explanation:

I looked this up and found that when you flip a coin 10 times you get 2^10 = 1024 but including other possibilities there are only 1000 combinations. Meaning that there are 2 possible outcomes for every coin flip and in order to find those combinations you have to multiply 2 to itself for however many times you were to flip a coin.

For Example: Flip a coin 3 times there are 2 possibilities for every time you flip it. So the answer would be 2*2*2=8 combinations.

I hope this helps. :)

The answer is correct that

Galina was correct when she said: there are 2 possible outcomes.

Elroy was correct when he said: multiply the 10 outcomes by 1/2

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

As the coin is flipped 10 times and there are to possible outcomes of coin head and tail.

So, [tex]2^{10}[/tex] = 1024

In order to find the combination we have to multiply the number 2 to the number itself or raise the power of 2 to the number of times we have flipped the coin.

Let us take a case,

If we have flipped a coin 5 times and there are only two possibilities.

The answer will be=  [tex]2^{5} or 2*2*2*2*2*2[/tex] = 32 combination.

Answer:

x = 4 cm

Step-by-step explanation:

The area of an rectangle is the product of its length and its breadth.

From the diagram, the length = 13 + x and the breadth = 7 + x. Therefore:

Area of the rectangle = length × breadth = (13+x)(7+x)

But the area = 187 cm,

⇒ 187 = (13+x)(7+x)

187 = x² + 20x + 91

Subtracting 187 from both sides

x² + 20x + 91 - 187 = 187 -187

x² + 20x - 96 = 0

x² + 24x - 4x - 96 = 0

x(x + 24) - 4(x + 24) = 0

(x - 4)(x + 24) = 0

x - 4 = 0 or x + 24 = 0

x = 4 or x = -24

Since x cannot be negative therefore, x = 4 cm

Length = 13 + 4 = 17 cm

Breadth = 7 + 4 = 11 cm

Answer: A - 42

Step-by-step explanation:

Let x= ones digit, y=tens digit

1st (original number) :

7(x+y)=10y + x

2nd (new number by reversing the digits): 18+x+y=10x+y

simplifying:

1st condition: 6x=3y

2nd condition: x=2

substituting x=2 to 6x=3y

y=4

Step-by-step explanation:

Answer:

A (1,0), B (3,0) Q (2,-1) P(0,3)

Step-by-step explanation:

A(1,0) B (3,0) these are the roots of the current graph so the factors or the x-intercepts.

Q is the minimum so it is halfway between the x-intercepts

halfway = 3+1/2 , x=2

plug x=2 into the equation

y=(2-1)(2-3)

y=  -1

therefore Q = (2,-1)

P is the y-intercpet when x=0, so plug x=0 into the equation

y=(0-1)(0-3) = 3

therefore Q =

Answer:

There are 8 possible outfit choices

Step-by-step explanation:

you multiply 2 times 4 because there each shirt can pair to each pants once

Answer:

Let's see the first two points: (-7, 5) and (-5, 9)

The line passes these points has a form of: y = Mx + b

=> 5 = (-7)M + b

   9 = (-5)M + b

Subtract the 1st equation from 2nd equation, we have:

4 = 2M

=> M = 2

Substitute M back into 1st equation:

=> 5 = (-7)*2 + b

=> b = 19

=> y = 2x + 19

or y - 5 = 2x + 14

or y - 5 = 2(x + 7)

=> Option A is correct

Hope this helps!

:)

Answer:

A

Step-by-step explanation:

The difference between the values of y are constant, that is

17 - 13 = 13 - 9 = 9 - 5 = 4

This indicates the relationship is linear.

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 7, 5) and (x₂, y₂ ) = (- 5, 9) ← 2 ordered pairs from the table

m = [tex]\frac{9-5}{-5+7}[/tex] = [tex]\frac{4}{2}[/tex] = 2

Use any ordered pair from the table for (a, b)

Using (a, b) = (- 7, 5), then

y - 5 = 2(x - (- (- 7)) , that is

y - 5 = 2(x + 7) → A
