Answer:

y-intercept: (0,4)

Slope: -1/3

Step-by-step explanation:

y-intercept: (The y-axis is the vertical axis.) this is where the line crosses the y-axis. (This always occurs when x = 0.) From the graph, the purple line crosses the y-axis at 4 therefore: y-intercept = (0,4)

slope:

slope = rise / run

this means slope = y/x

first step is to locate to places along the purple line that cross the grid boxes neatly. this occurs at (-3,5), (0,4), and (3,3).

Taking any two of the three intersections listed above one can find the slope of a line. To demonstrate solving, we will solve for slope three way using the same method, different points:

___________________________________

Option 1: (-3,5), (0,4)

[With ordered pairs, x is always listed first followed by y]

slope between two points = change in y / change in x

so slope = (5 - 4) / (-3 - 0)

slope = 1/-3

slope = -1/3

___________________________________

Option 2: (0,4), (3,3)

[With ordered pairs, x is always listed first followed by y]

slope between two points = change in y / change in x

so slope = (4 - 3) / (0 - 3)

slope = 1/- 3

slope = -1/3

___________________________________

Option 3: (-3,5), (3,3)

[With ordered pairs, x is always listed first followed by y]slope between two points = change in y / change in x

so slope = (5 - 3) / (-3 - 3)

slope = 2/- 6

reduce to:

slope = 1/- 3

slope = -1/3

___________________________________

NOTES: a tip to check if a slope will be positive or negative can be found by just looking at the graph. If the lower part of the line is to the left, the slope will be positive. If the lower part of the line is to the right (as in question), the slope will be negative.

Answer:Pi

Step-by-step explanation:

The ratio of circumference of circle to its diameyer is the number π ,a mathematical constant, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi".

Answer:

i think it is C

Step-by-step explanation:

Answer:

When we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)

Applying the concept:

Given A(-2, 4) and A'(-0.25, 0.5), which means , and .

Substituting -2 for x in the equation , we get the below equation:

Now we need to find B' and C' by multiplying 0.125 with the x-coordinate and y-coordinate.

-----

x-coordinate of B is -2, y-coordinate of B is 8

x-coordinate of B'

y-coordinate of B'

So

-----

x-coordinate of C is 6 and y-coordinate of C is 4

x-coordinate of C'

y-coordinate of C'

So

Conclusion:

The below are the TRUE statements:

(i) The coordinates of C' are (0.75, 0.5)

(ii) The scale factor is 1/8

(iii) The coordinates of B' are (–0.25, 1).

Answer:

41.63

Step-by-step explanation:

Circumference = 2pi(r)

26.5 / 2 = 13.25 (radius)

2pi(13.25) = 83.25 (circumference of the full circle)

83.25 / 2 = 41.625 or 41.63

Answer:

yes

Step-by-step explanation:

(81/5)/(7/4)=81*4/5*7=324/35

Answer:26

Step-by-step explanation:

Yes, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Given is the equation -

4n − 3 = −2n + 9

We have -

4n − 3 = −2n + 9

For n = 2, we can write -

4 x 2 - 3 = - 2 x 2 + 9

8 - 3 = 9 - 4

5 = 5

So, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Therefore, yes, n = 2 is the solution of the equation 4n − 3 = −2n + 9.

Answer:

x = 14

y = 39

A. 114F degrees

Step-by-step explanation:

well for the first one they're asking for a simliar ratio to show the relationship between all of the points

so we must line up and simplify all the points to try and find a simliar ratio

so the ratio is 2/3

because if we simplify 8/12 and 16/24 they both come down to 2/3

so if we plug that in to find x we get x = 14

and then if we that in for y we get y = 39

now for the second question this is a pretty simple addiction subtraction kind of problem but here's some help

if the highest temperature was 93 and the lowest was -21 we just have to find how many degrees are in between those two

therefore leaving us with the answer

A. 114F degrees

hope this helps you out, if it doesnt please make sure to like and give me the brainliest if possible!

Answer:

Step-by-step explanation:

i know that the second one is 114°

im not sure abt the first one

z= -300

Step-by-step explanation:

Flip the equation so it looks like: 0.07z = -21

Then, divide it by 0.07 on both sides, which gets you -300.

You could also divide it by 7 and then multiply that answer by 100 if you want an extra step
