11. A line passes through the point (2, 3) and has a slope of 2.
11a. What are the steps you take to find the y-intercept?
11b. What is the equation of the line?
Answers
Answer:
11. y=2x-1
11a. you subtract 2 from the y and 1 from the x and draw your points accordingly to go down or you add 2 to the y and add 1 to the x to go up and plot the points accordingly or you could just draw a graph like i did if you dont wanna do it by math lol. :)
11b. oh i guess i already answered this but y=2x-1

Answers
Answer:
y = 1.9 units (nearest tenth)
Step-by-step explanation:
recall that for a right triangle with angle θ
tan θ = opposite length / adjacent length
in our case we are given the following:
θ = 15 deg
opposite length = y
adjacent length = 7
substituting these into the equation:
tan θ = opposite length / adjacent length
tan 15 = y / 7
y = 7 tan 15
y = 1.8756
y = 1.9 units (nearest tenth)
(BRAINLIEST + 30 POINTS) Gumballs cost $0.50 each, and jawbreakers cost $0.30 each. Bob has $3.00 to spend on candy.
Create an inequality that represents the number of gumballs and jawbreakers Bob can buy.
Answers
Answer:
3 gumballs and 5 jawbreakers = $3.00
Step-by-step explanation:
30 x 5 = $1.50 (One dollar and 30 cents)
50 x 3 = $1.50 (One dollar and 30 cents)
and if you add those together you get $3.00 because
50 + 50 = 100 or in this question $1.00 and when you add
$1.50 + $1.50 = $3.00
hope this helps!
Answer:

The slope of the graph shown below is
Answers
Answer: -5/4
Step-by-step explanation:
A slope is also known as the gradient of a line. The slope of the given equation is -5/4.
What is a Slope?A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.
slope = (y₂-y₁)/(x₂-x₁)
The given line passes through two points (0,2) and (-4,7), therefore, the slope of the given line can be written as,
Slope, m = (7 - 2)/(-4 - 0) = 5/-4
Hence, the slope of the given equation is -5/4.

What is 2M?

Answers
Answer:
2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.
Step-by-step explanation:
Given the matrix
[tex]M=\begin{pmatrix}3&5\\ -4&0\end{pmatrix}[/tex]
Multiplying by 2 will basically be a scalar multiplication.
Therefore, multiply each of the matrix elements by a scalar.
[tex]2M=2\begin{pmatrix}3&5\\ \:-4&0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}2\cdot \:3&2\cdot \:5\\ 2\left(-4\right)&2\cdot \:0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Hence, 2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.

On a conveyor belt, there can only be two boxes moving at a time. The total weight of the boxes cannot be more than 300 pounds. Let x and y represent the weights of the two boxes on the conveyer belt.
a. Write an inequality that describes the weight limitation in terms of x and y.
b. Two boxes are to be placed on the conveyor below. The first box weighs 175 pounds. What is the maximum weight of the second box?
Answers
Answer:
The maximum weight of the second box is 125 pounds. (The box can weight less than 125 pounds, but no more than 125 pounds since the total weight of the boxes cannot be more than 300 pounds.)
Step-by-step explanation:
x+y ≤ 300
175+y ≤ 300
Substract 175 on both sides:
y ≤ 125
The inequality that describes the weight limitation in terms of x and y is -
x + y ≤ 300 and the maximum weight of second box can be 125 pounds.
We have a conveyor belt such that there can only be two boxes moving at a time. The total weight of the boxes cannot be more than 300 pounds.
It is given in the question to assume let x and y represent the weights of the two boxes on the conveyer belt.
We have to find -
a) - inequality that describes the weight limitation in terms of x and y.
b) - If two boxes are to be placed on the conveyor belt and first box weighs 175 pounds then what is the maximum weight of the second box?
What is inequality?Inequality in mathematics is a relation that is used to compare two or more algebraic expressions.
According to the part 'a' of the question -
The inequality that describes the weight limitation in terms of x and y is -
x + y ≤ 300
According to part 'b' of the question -
x = 175 pounds
The maximum weight of second box can be found out by substituting the value of 'x' in inequality in part a.
175 + y ≤ 300
y ≤ 125
Hence, the maximum weight of second box can be 125 pounds.

Expo Milano 2015 was visited by 22.2 million people. It is expected that Expo 2020 Dubai will
be visited by 25 million people. Find the percent of change.
Answers
Answer:
12.6% is the percent of change.
Step-by-step explanation:
As Expo Milano 2015 was visited by 22.2 million people.
And it is expected that Expo 2020 Dubai will be visited by 25 million people.
so
25 - 22.2 = 2.8 million people
so dividing the 2.8 by 22.2 would give us the percentage of increase.
2.8/22.2 = 0.126 which is = 12.6%
Therefore, 12,6% is the percent of change.
