Is the C

Because 3+(-1) = 2

2:2= 1

Answer:

C

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

We can find the slope since we have two points

m = (y2-y1)/(x2-x1)

   = (-12-8)/(3 - -1)

   = (-12-8)/(3+1)

   = -20/4

   = -5

-5

We can find the slope since we have two points

m = (y2-y1)/(x2-x1)

  = (-12-8)/(3 - -1)

  = (-12-8)/(3+1)

  = -20/4

  = -5

Answer:

b<58/5

Step-by-step explanation:

82 ÷ 15 = 5.4

Mixed number form: 5 ⁷/₁₅

Answer:

the answer is 5.4

Step-by-step explanation:

A graph has a constant rate of change when the graph is linear and portrays a straight line. The slope will remain constant which forms the straight line in the graph.

Answer:

Because it is a straight line

Step-by-step explanation:

If it changed there would be curves, points, corners, zig zags, since this is straight, that means the R.O.C commonly known as slope, is not changing

Pls give brainliest i had 40 down to 1 for no reason and a thx ;)

I always thank those who give me brainliest via their profile and comments

Answer:

2968

Step-by-step explanation:

First make 112% into a decimal, now its 1.12, add all the scooters' sales from all years and multiply by 1.12 then add that number to the total sales of the scooters

Answer:

725 + 579 + 696 = 2000 (What a coincidence)

112% = 112 / 100 = 1.12

Multiply the increase

2000 x 1.12 = 2240

2240 is the amount of scooters sold.

Step-by-step explanation:

I don't know, sorry. :(

Answer:

D

Step-by-step explanation:

Because the angle with measure 82 and angle 1 are corresponding angles, their angles measure must be equal, and therefore angle 1 has measure of 82 as well. Since angles 1 and 2 are a linear pair, they must be supplementary, and angle 2 is therefore 180-82=98 degrees. Hope this helps!

[tex]answer = 98 °\\ solution \\ < 1 = 82(being \: corresponding \: angless) \\ < 1 + < 2 = 180(sum \: of \: angle \: in \: straight \: line) \\ or \: 82 + < 2 = 180 \\ or < 2 = 180 - 82 \\ < 2 = 98° \\ hope \: it \: helps \\ good \: luck \: on \: your \: assignment[/tex]

Answer:

b = 68

Step-by-step explanation:

Complementary angles add to 90 degrees

a+b = 90

22+b = 90

Subtract 22 from each side

b = 90-22

b = 68

Answer:

68 degrees

Step-by-step explanation:

Complementary Angles: The sum of the angles is 90 degrees.

If angle a is 22 degrees, then...

a + b = 90

22 + b = 90

22 - 22 + b = 90 - 22

b = 68

That means that the measure of angle b is 68 degrees.

I hope this helps! Have a great day!

Answer:

Coordinates of M = [tex]\left ( -2,4 \right )[/tex]

Step-by-step explanation:

Given: AM:MB = 1:4, A has coordinates (-4, 3) and B has coordinates (6, 8)

To find: coordinates of M

Solution:

According to section formula, if M(x, y) divides line joining points [tex]A(x_1,y_1)\,,\,B(x_2,y_2)[/tex] in ratio [tex]m:n[/tex] then coordinates of point M are [tex]\left ( \frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n} \right )[/tex]

Put [tex]A(x_1,y_1)=(-4,3)\,,\,B(x_2,y_2)=(6,8)\,,\,m:n=1:4[/tex]

Therefore,

[tex](x,y)=\left ( \frac{6-16}{1+4},\frac{8+12}{1+4} \right )=\left ( -2,4 \right )[/tex]

Answer:

Bottom left

Step-by-step explanation:

For it to be scalene, all 3 sides must be of different length, so cross off D. Acute means all angles are less then 90°, so cross off the top 2.

Answer:

area of the sector  =4π/3  cm²

Step-by-step explanation:

To find the area of the sector, we will follow the steps below;

first write the formula for finding area of a sector

area of a sector = Ф/360  ×  πr²

where r is the radius

from the question given

Ф= 30       and radius = 4 centimeters

we can proceed to insert the values into he formula above

area of a sector = Ф/360  ×  πr²

                             =30/360  ×π×4²

                             =1/12 ×π×16

                             =16π /12

                              =8π/6

                             =4π/3

area of the sector  =4π/3  cm²

Answer:

[tex]48cm^2[/tex]

Step-by-step explanation:

Use the area of rectangle formula.

[tex]A=lw[/tex]

[tex]A=12 \times 4[/tex]

[tex]A=48[/tex]

Answer:

[tex]6\frac{2}{3}[/tex]

Step-by-step explanation:

OK, so basically I'm pretty sure that you add all of them together and put it as a fraction over 3 so basically  [tex]\frac{20}{3}[/tex] then simplify it into [tex]6\frac{2}{3}[/tex]

Answer:

the one with 47:is 43

the one with 52 is 38

the one with 63 is 27

and the one with 45 is 45

Step-by-step explanation:

these angles equal to 90

so you must subtract them from 90

Answer:

5: x=43

6: x=38

7: x=27

8: x=45

Answer:

"Simplifying rational expressions will make the further calculations easier since the variables to work with will usually be smaller.

To determine that a rational expression is in simplest form we need to make sure that the numerator and the denominator have no common variables."

Answer:

6.25%

Step-by-step explanation:

75 - 80 = -5

Absolute value of -5 is positive so -5 = 5

5 ÷ 80 = 0.0625 (1/16)

0.0625 × 100 = 6.25%
