Find the values of a and b.

Answer:

-6

Step-by-step explanation:

-(-4)2+3(-4)−2 would be the equation so you'd just have to solve it using PEMDAS

Answer:

Step-by-step explanation:

you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.

so 70 + 40 + 20 + 60 + 20 + 40 i believe.

this all equals 250.

ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.

it is i think :(

Step-by-step explanation:

Answer:

y = x - 7

Step-by-step explanation:

Parallel lines have the same gradient in this case 1 is the gradient.

Using the point (8,1) we can form our own equation.

1 will be y, 1 will be m, 8 will be x

All we have to do is find C in order to form the equation y=mx+c

1 = 1(8) + c

1 = 8 + c

C = - 7

Therefore;

y = x - 7

Answer:

it depends on how big the rectangle is though...

Step-by-step explanation:

Answer:

6x + 10

Step-by-step explanation:

Given,

Length ( l ) = 3x

Breadth ( b ) = 5

To find : Perimeter of the rectangle = ?

Formula : -

Perimeter of the rectangle = 2 ( l + b )

Perimeter of the rectangle

= 2 ( 3x + 5 )

= 2 ( 3x ) + 2 ( 5 )

= 6x + 10

Answer:

60

Step-by-step explanation:

if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20

Answer:

The Answer is 30 questions in total.

Step-by-step explanation:

1. The first thing you would want to do is to break down this question.

For every 6 questions, this is 20% of the test done.

2. You now would want to divide 100% (the full amount on the test) by 20%.

100%/20% = 5

3. Now, multiply both to get your answer.

6·5= 30

20%x5= 100%.

Therefore, the total amount of questions on the test is 30 questions.

Answer:

Surface area: 277.59 in^2

Volume: 434.89 in^3

Step-by-step explanation:

Radius = C/(2*pi)

29.5/3.14 = 9.39

Radius = 9.39/2 = 4.7 in

A = 4 pi r^2

A = (4) (3.14) (4.7)^2

A = 277.59 in^2

Volume = (4/3) (pi)(r)^3

(4/3)(3.14)(4.7)^3

= 434.89 in^3

Answer:

Surface area: [tex]277.59[/tex] in^[tex]2[/tex]

Volume: [tex]434.89[/tex] in^[tex]3[/tex]

Explanation:

Radius = C/([tex]2[/tex]*[tex]Pi[/tex])

[tex]29.5/3.14[/tex] = [tex]9.39[/tex]

Radius = [tex]9.39/2[/tex] = [tex]4.7[/tex] in

A = [tex]4[/tex] [tex]Pi[/tex] r^[tex]2[/tex]

Answer:

A right triangle needs to have all the sides of the same length. Since this obviously does not, it is not a right triangle. Infact, this is a scalene triangle because all of its sides are unequal.

40.6 miles and $9.77

Step-by-step explanation:

[Number 1]

8.12 × 5

= 40.6 miles

[Number 2]

2.79 × 3 ½

= 2.79 × 3.5

= 9.765

≈ $ 9.77

Answer:

In order to calculate the slope, you'll need 2 ordered pairs (x, y).

The formula for calculating the slope is:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

where m = slope

(x1, y1) = first ordered pair

(x2, y2) = second ordered pair

Regardless of which values for the (x1, y1) and (x2, y2) you choose, you would still end up with the same slope (as long as it's done correctly).

As an example, let's say you have the following set of points:

(2, 4) (8, 1)

Let (x1, y1) =  (2, 4)

     (x2, y2) = (8, 1)

Plug these values into the slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{1 - 4}{8 - 2} = \frac{-3}{6} = -\frac{1}{2}[/tex]

Therefore, the slope of the line is - 1/2.

To prove that you'll end up with the same value for the slope:

This time, let (x1, y1) =  (8, 1)

                     (x2, y2) = (2, 4)

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{4 - 1}{2 - 8} = \frac{3}{-6} = - \frac{1}{2}[/tex]

Therefore, the value of the slope is still -1/2.

Answer:

y = -3x + 4

Step-by-step explanation:

To find the slope, use rise over run with two points. The first point (0,4) to the second point (-2,-2) is 6 units down and 2 units to the right, so you can set up a fraction to solve for the slope:

-6/2 = -3

To find the y-intercept,find the point where the x-value is 0. That point is (0,4),so the y-intercept is 4.

mx represents the slope, so mx is -3x and b is the y-intercept, so that value is 4.

Answer:

y = -3x + 4

Step-by-step explanation:

m = the slope (rise/run)

b = y-intercept

we can see that the rise is 6 (based on the two points) and the run is 2 (based on the labeled points)

- that means that m = 6/2 or m = 3

y = 0  when x = 4, so the y-intercept is 4, or b = 4

put it together!

y = 3x +b

BUT WAIT!!

- the line is decreasing which means that your equation should be negative, so put a negative symbol before 3x.

   - why? the rise is decreasing!

final equation --------> y = -3x + 4

Answer:

a. pants + tax + drink ≤ 60 b. $56.16

Step-by-step explanation:

60-1.5 = 58.5 = money left for pants+tax

58.5/100 = 0.585 = 1%

0.585x 4= $2.34 = highest possible tax

58.5 - 2.34 = $56.16 most

pants + tax + drink ≤ 60

Answer:
