Step-by-step explanation:

So in the equation given, y = 2x - 3

you substitute x for whats given in the table in the x column.

Example

In the graph the first number under the x colum is -1.

y = 2x - 3 in the equation you take out x and put -1.

So now the equation becomes y = 2 × -1 - 3.

Using bedmas to solve the question you should get -5

Which now means y = -5

To plot the point now x would be -1 and y would be -5 (-1, -5)

Same thing for the second number in the x Column.

y = 2 × 1 - 3 which equals -1

To plot it

x = 1 y = -1. (1, -1)

And for the last number 3.

Agai. You substitute x for 3 which makes the equation y = 2 × 3 - 3

this gives you 3 and to plot it

x would be 3 and y would be 3

Find the slope of the line through each pair of points (6, -10) , (-15 , 15)

dem82 [27]

<h3>Answer:</h3>

$\boxed{\boxed{\pink{\bf \leadsto The \ slope \ of \ the \ line \ is \ \dfrac{-25}{21}.}}}$

<h3>Step-by-step explanation:</h3>

Two points are given to us and we need to find the slope of the line . The slope of the line passing through points $\bf (x_1,y_1 ) \ \& \ (x_2,y_2)$ is given by ,

$\qquad\boxed{\red{\bf Slope = tan\theta=\dfrac{y_2-y_1}{x_2-x_1}}}$

Here , the points are ,

( 6 , -10 )
( -15 , 15 )

$\bf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1} \\\\\bf\implies Slope =\dfrac{15-(-10)}{-15-6} \\\\\bf\implies Slope = \dfrac{15+10}{-21}\\\\\bf\implies Slope =\dfrac{-1(25)}{-1(-21)}\\\\ \bf\implies\boxed{\red{\bf Slope =\dfrac{-25}{21}}}$

<h3>★ Hence the slope of the line joining the two points is -25/21 .</h3>

A recipe calls for 120 mL of milk for each 200 g of flour.Juan is going to use 1 pound of flour. Estimate the number cups of mil

Ratling [72]

Answer:

1 cup of milk Juan should use.

Step-by-step explanation:

Given:

A recipe calls for 120 ml of milk for each 200 g of flour.

Juan is going to use 1 pound of flour.

Now, to estimate the number of cups of milk.

Let the quantity of milk be $x.$

Now, to convert the pound of flour to gram.

1 pound = 453.59 g.

So, Juan is going to use 453.59 g of flour.

As, given recipe calls for 120 ml of milk for each 200 g of flour.

So, 120 ml is equivalent to 200 g.

Thus, $x$ is equivalent to 453.59 g.

Now, to solve by using cross multiplication method:

$\frac{120}{200} =\frac{x}{453.59}$

By cross multiplying we get:

$54430.8=200x$

Dividing both sides by 200 we get:

$272.154=x$

$x=272.154$

The quantity of milk = 272.154 ml.

Now, converting the quantity into cups by conversion factor:

1 ml = 0.004 cup.

So, 272.154 ml of milk is:

272.154 × 0.004

=1.088 cups.

Estimating the number = 1 cup.

Therefore, 1 cup of milk Juan should use.

Answer:

121.5 cm^2.

Step-by-step explanation:

Each face has area 4.5^2 = 20.25 cm^2.

There are faces so the total surface area = 20.25 * 6.
