Slope of required line is 4

Step-by-step explanation:

We need to find the slope of the values given in the table

The formula used to find slope is:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

Here $y_1=-25, x_1=-6, y_2=-1, x_2=0$

Putting values and finding slope:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

$Slope=\frac{-1-(-25)}{0-(-6)}$

$Slope=\frac{-1+25}{6}$

$Slope=\frac{24}{6}$

$Slope=4$

Now, $y_1=-1, x_1=0, y_2=19, x_2=5$

Putting values and finding slope:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

$Slope=\frac{19-(-1)}{5-(0)}$

$Slope=\frac{19+1}{5}$

$Slope=\frac{20}{5}$

$Slope=4$

So, Slope of required line is 4

Write the equation of the line that passes through the given points (-6, 0) and (0, 3)

Tomtit [17]

Answer:

Step-by-step explanation:

Put (-6,0) and (0,3) into a table of values

form of the equation: mx+b

x -6 0

y 0 3

3/-6=-0.5 (m)

3=b (the value of y when x=0)

equation: y=0.5x+3

The linear equation of the initial (red ) incline would be y = __x +__

RideAnS [48]

Answer:

$y=\underline {1.5}x+\underline 0$

Step-by-step explanation:

From the graph,

The initial red incline is a straight line passing through the origin.

So, a straight line passing through the origin is of the form:

$y=mx+0$

Where, 'm' is the slope.

Now, the slope of a given as the change in y value to change in x value.

Consider the two end points of the red line (0, 0) and (4, 6).

The slope with two points $(x_1,y_1)\ and\ (x_2,y_2)$ on the line is given as:

$m=\frac{(y_2-y_1)}{(x_2-x_1)}$

Plug in $x_1=0,y_1=0,x_2=4,y_2=6$ . Therefore, slope is:

$m=\frac{6-0}{4-0}\\m=\frac{6}{4}=1.5$

Hence, the equation of the initial red incline is:

$y=\underline {1.5}x+\underline 0$

Answer:

1. The probability that the T-shirt will be grey :-

=》

$\frac{2}{20}$

=》

$\frac{1}{10}$

=》

$0.1$

hence, the probability of grey t-shirt is 0.1

2. The probability that the T-shirt will not be red :-

=》

$1 - \frac{4}{20}$

=》

$1 - \frac{2}{10}$

=》

$1 - 0.2$

=》

$0.8$

The probability that the T-shirt will not be red is

0.8

3. He takes one of his blue T-shirts at random.

What is the probability that the T-shirt is light blue

total blue t-shirts = 5

so, the probability of choosing light blue t-shirt is

=》

$\frac{1}{5}$

=》

$\frac{2}{10}$

=》

$0.2$

hence, the probability of choosing light blue t-shirt is 0.2

Jocelyn and Madelyn go to the movie theater and purchase refreshments for their friends.

let's make p stand for popcorn and d for drinks. Using those variables, we can create our equations:

2p + 3d = 18.25

4p + 2d = 27.50

From this, we can use substitution or elimination to solve:

For substitution, in the second equations, we could factor out a 2, divide both sides by 2, and then move the left over 2p to the other side to isolate d to put into the first equation.

For elimination, we can multiply the first equation by -2 so that we can remove the 4p and focus on solving for d.

I'll be using elimination in this case:

-2(2p + 3d = 18.25) --> -4p - 6d = -36.50

-4p - 6d = -36.50

4p + 2d = 27.50

-4d = -9.00

d = 2.25

4p + 2 * 2.25 = 27.50

4p + 4.50 = 27.50

4p = 23.00

p = 5.75

Now let's check our answer:

2 * 5.75 + 3 * 2.25 = 18.25

11.50 + 6.75 = 18.25

18.25 = 18.25

So drinks cost $2.25 and popcorn $5.75
