Which of the following equations represents the line that is graphed on the coordinate grid below

vladimir2022 [97]

Answer:

Step-by-step explanation:

the factor of x in the equation is the slope, which is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.

going from the left point to the right point x changes by +3 units, and y changes by -1 unit.

so, the slope (and factor of x in the equation) is -1/3.

and the constant term in the equation is the y (axis) intercept of the line.

this is the y value, when x = 0 (intercepting the y axis).

and we see in the graph, when x = 0, the line goes through y = 2.

so, the equation has to be

y = -1/3 × x + 2

therefore, C is the right answer.

Plz help number 3d ( can you pls show ur steps of how you got the answer)

denis23 [38]

Answer:

$(\frac{13}{16},-\frac{3}{8})$

Step-by-step explanation:

Midpoint of a segment with the given endpoints $(x_1,y_1)$ and $(x_2,y_2)$ is defined by,

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

In this question endpoints of the segment are,

$Q(-\frac{3}{8},\frac{1}{8})$ and $R(2,-\frac{7}{8})$

Coordinates of the midpoint will be,

$(\frac{-\frac{3}{8}+2}{2},\frac{\frac{1}{8}-\frac{7}{8}}{2})$

= $(\frac{13}{16},-\frac{3}{8})$

Therefore, coordinates of the midpoint are $(\frac{13}{16},-\frac{3}{8})$ .

A checkers board is eight squares long and eight squares wide. The area of each square is 14 cm². Estimate the perimeter of the

Tamiku [17]

Answer:

Perimeter of the board is 119.7 cm.

Step-by-step explanation:

We are given that,

Area of each square = 14 cm²

i.e. $Side^2=14$

i.e. $Side= \sqrt{14}$

i.e Side = 3.74 cm

So, we get the side of each square is 3.74 cm.

Since, Perimeter of a square = $4a$

→ Perimeter of each square = $4\times 3.74$

→ Perimeter of each square = 14.96 cm

<em>Since, there are 8×8= 64 squares on the board.</em>

Thus, the perimeter of the board = 8 × Perimeter of each square.

i.e. Perimeter of the board = 8 × 14.96

i.e. Perimeter of the board = 119.68 cm

Hence, the perimeter of the board rounded to the tenths is 119.7 cm.

What does the word “change “ tell you to do in “keep change flip” for dividing fractions? A) change the sing to multiplication b

Harman [31]

Answer:

Step-by-step explanation:

Multiply by the reciprocal, also sometimes referred to as "Keep, Change, Flip." Here is how it works. You rewrite the division question as a multiplication question by flipping the second fraction over. Next, keep the first number, change the division to multiplication and then flip the second fraction over.
