1/5 as a a decimal would be 0.20 because if you multiply 0.20 by 5 you get 1

Answer:

B

Step-by-step explanation:

First convert [tex]\frac{1}{5}[/tex] to a decimal : 0.2

y represents how many strawberries Zoe ate

x represents how many strawberries Nora ate

If you take the equation- y = 0.2x and plug how many strawberries Nora ate you would claculate how many Zoe ate.

       For example: say Nora ate 10 strawberries the equation would be- y(how many strawberries Zoe ate) = 0.2 · 10 ( the naumber of strawberries Nora ate)

f(-2) = +2

Step-by-step explanation:

Let x = -2

So,

f(x) = 4x + 10

Substituting the value of x gives ,

f(-2) = 4 × (-2) + 10 = 10 - 8 = 2

Answer:

The graph shows a line of best fit because the points are plotted evenly above and below the line.

Step-by-step explanation:

The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

We have a line of best fit shown in the picture.

As we know if the slope of the line is positive then the correlation will be positive.

From the line of best fit:

Because the points are evenly spaced above and below the line, the graph displays a line of best fit.

Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

Answer:

im think the bowl weighs 49.5 grams by itself

Step-by-step explanation:

405/2= 202.5

765/5=153

202.5-153=49.5

9514 1404 393

Answer:

  165 grams

Step-by-step explanation:

We can write an equation for the total weight (y) as a function of the number of cups of flour (x). The y-intercept of that equation will be the weight of the bowl.

The two-point form of the equation of a line is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

The two points we are given are (2, 405) and (5, 765).

  y = (765 -405)/(5 -2)(x -2) +405

  y = 360/3(x -2) +405 . . . . simplify a bit

  y = 120x -240 +405 . . . . . eliminate parentheses

  y = 120x +165 . . . . . . . . . . combine terms

The bowl by itself weighs 165 grams.

Answer:he should build them 25x10

Step-by-step explanation:

Encik Ahmad can build 10 square plots with three different sizes.

Rectangle is a polygon in two dimensional geometry which has four sides and four angles and each angle being right angles.

Length of the rectangular plot = 85 m

Width of the rectangular plot = 30 m

We have to find the number of square plots Encik Ahmad can built of three different sizes.

For that first we take a 45 m length of the plot.

Divide it to three equal lengths. We get three lengths with each 15 m length.

Along the width also, divide into two equal width, each having a width of 15 m.

Each 15 m length, we will get two square plots.

Along 45 m length, we get 3 × 2 = 6 square plots.

The remaining rectangle has length 40 m and width 30 m.

Divide this length as 30 m and 10 m.

So we get a square of dimension 30 m.

Remaining is a rectangle whose remaining length is 10 m and width 30 m.

Along the width, divide into three equal widths, each 10 m.

So there we get three square plots with side length 10 m.

So we have 10 square plots, 6 having the side length 15m, 1 having the side length 30 m and 3 having the side length 10 m.

Hence he get 10 square plots having three different sizes as 15 m, 30 m and 10 m.

Answer:

(x,y) = (0,0)

Step-by-step explanation:

Let both as equation (1) and (2)

put equal both sides -x = -7x

-x + 7x = 0

6x = 0

x = 0

put it in 2nd equation

y = -7(0)

y = 0

Answer:

y = - [tex]\frac{3}{4}[/tex] x + 3

Step-by-step explanation:

Assuming you require the equation of the line

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{3}{4}[/tex] , thus

y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation

To find c substitute (- 4, 6) into the partial equation

6 = 3 + c ⇒ c = 6 - 3 = 3

y = - [tex]\frac{3}{4}[/tex] x + 3 ← equation of line

The equation of a line with given coordinate point and slope is y = -3/4 x + 3.

The given coordinate point is (-4, 6) and slope (m) = -3/4.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Put, (x, y) = (-4, 6) and m=-3/4 in y=mx+c, we get

6 = -3/4 (-4) + c

⇒ 6 = 3 + c

⇒ c = 3

Substitute m=-3/4 and c=3 in y=mx+c, we get

y = -3/4 x + 3

Therefore, the equation of a line with given coordinate point and slope is y = -3/4 x + 3.
