There’s a few ways to approach this. You just need to figure out which equations are on that graph. I’d start by identifying the equations for the lines. Remember y=mx+b where mx is the slope and b is the y-intercept. Let’s start with the y-intercepts. They’re labeled for you. One is (0,4) and the other is (0,-4). So we have y=mx+4 and y=mx-4. Next, we need to find the slope. You can count the boxes to do that. Find a neat spot where the line crosses a corner (the y-intercept is often a good place to start) and make a sort of triangle using the line as one side. Count the boxes it takes to get up and over to the next intersection at a corner. The line that crosses at (0,4) goes up (rise) one and over (run) one equally. Rise over run, 1/1x. That can be simplified to just x. So one line is y=x+4. The other line goes down two for every one box it goes over. Remember that when it goes down, it’s negative. So that’s -2/1x, or just -2x. The equation is y=-2x-4. Both of those answers are only present in option J.

What is Parallel lines?To determine whether or not two lines are parallel, the formula for parallel lines is used. When we have the slopes of two lines that we want to compare, we can use the parallel line formula. The parallel lines' distances never change.
Given Equation
y = 7x + 5
and line k
line k is parallel to equation y = 7x + 5
for parallel lines
The formula for determining whether two lines are parallel is as follows for any two lines with the equations y = m₁ x + c₁ and y = m₂x + c₂:
where m₁ and m₂ are the slopes of the two lines. m₁ = m₂.
given equation y = 7x + 5,
here m₁ = 7 and c₁ = 5
the line which is parallel to equation should be
y = 7x + c
where m₂ = m₁ = 7 and c₂ = c
Hence equation y = 7x +c is parallel to given equation.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of people who voted for the comedy film be = A
Now , the equation will be
The total number of people = 280 people
The percentage of people who voted for the best comedy film = 65 %
So , number of people who voted for the comedy film A = percentage of people who voted for the best comedy film x total number of people
Substituting the values in the equation , we get
Number of people who voted for the comedy film A = ( 65 / 100 ) x 280
On simplifying the equation , we get
Number of people who voted for the comedy film A = 0.65 x 280
Number of people who voted for the comedy film A = 182 people
Therefore , the value of A is 182 people
Hence , the number of people is 182 people

Topic - Arithmetic Progression ( AP )Given - a general term for a sequence.To find - the 150th term of the given sequenceso let's start ~
General term , [tex] A_{n} [/tex] = 3n + 10
let's consider certain values of n to get some information with us which will help us solve the problem further !
let's first consider , n = 1 ! then ,
[tex]3n + 10 = 3(1) + 10 \\ \dashrightarrow \: 13[/tex]
now , let's consider n = 2
[tex]3n + 10 = 3(2) + 10 = 6 + 10 \\ \dashrightarrow \: 16[/tex]
then , let's consider n = 3
[tex]3n + 10 = 3(3) + 10 = 9 + 10 \\ \dashrightarrow \: 19[/tex]
hence ,
now we've with us an AP which is as follows -
[tex]13 \: , \: 16 \: , \: 19 \: ......[/tex]
from this Arithmetic Progression ,
we can know that
a = first term = 13
d = common difference = 16 - 13 = 19 - 16 = 3
now ,
[tex]A _{n} = a + (n - 1)d \\ \implies \: A _{150} = 13 + (149)(3) \\ \implies \: A _{150} = 13 + 447 \\ \pink{\implies \: A _{150} = 460}[/tex]

Explanation:
Use the pythagorean trig identity [tex]\sin^2(\theta)+\cos^2(\theta) = 1[/tex] and plug in the fact that [tex]\cos(\theta) = \frac{8}{17}\\\\[/tex]
Isolating sine leads to [tex]\sin(\theta) = -\frac{15}{17}\\\\[/tex]. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
[tex]\sin(2\theta) = 2\sin(\theta)\cos(\theta)\\\\\sin(2\theta) = 2*\left(-\frac{15}{17}\right)*\left(\frac{8}{17}\right)\\\\\sin(2\theta) = -\frac{240}{289}\\\\[/tex]

For each value of y, determine whether it is a solution to -2y+75-5.
Is it a solution?
Answers
Answer:
• No
• Yes
• Yes
• No
Step-by-step explanation:
To determine if the 4 given values of y are solutions to the inequality, start by solving the inequality. Solving an inequality is just like that of an equation, except that the direction of the sign changes when the inequality is divided by a negative number.
-2y +7≤ -5
Subtract 7 on both sides:
-2y≤ -5 -7
-2y≤ -12
Divide by -2 on both sides:
y≥ 6
This means that the solution can be 6 or greater than 6.
-10 and 3 are smaller than 6 and are not a solutions, while 7 and 6 satisfies the inequality and are therefore solutions.
_______
Alternatively, we can also substitute each value of y into the inequality and check if the value is less than or equal to -5.
Here's an example to check if -10 is a solution.
-2y +7≤ -5
When y= -10,
-2y +7
= -2(-10) +7
= 20 +7
= 27
Since 27 is greater than 5, it is not a solution to the inequality.

Given P(A) = 0.51, P(B) = 0.79, and P(A or B) = 0.66, are events A and B mutually exclusive?
Answers
Answer: No, the events are not mutually exclusive
Work Shown:
P(A and B) = P(A) + P(B) - P(A or B)
P(A and B) = 0.51 + 0.79 - 0.66
P(A and B) = 0.64
Since the result is not zero, this means the events are not mutually exclusive.
Mutually exclusive events are ones that cannot happen at the same time. Example: getting a "2" and a "3" on the same roll of a number cube.
Find the slope-intercept equation
Please help me
Answers
Answer:
[tex]y = -\frac{1}{3}x + 5[/tex]
Step-by-step explanation:
To being, slope intercept form is the infamous y = mx + b form. In which, m is equal to the slope and b is equal to the y-intercept. (1) To solve this, begin by finding two points of the line. One easy point to find is when x = 0 as it intersects with the y-axis. Two points are: (0,5) and (-3,6). (2) Next, use the slope formula to solve for the slope. The slope formula is [tex]\frac{y2-y1}{x2-x1}[/tex]. Plug in the y and x values; [tex]\frac{6-5}{-3-0}[/tex]. Simpliify the fraction; [tex]\frac{1}{-3}[/tex] --> [tex]-\frac{1}{3}[/tex]. Therefore -1/3 is our slope. (3) To solve for b, the y-intercept, set up the slope-intercept equation with the newfound slope (y = -1/3x + b) and plug in a point for the y and x values. Doing this will isolate the b so you can solve for it.
6 = -1/3(-3) + b
6 = 1 + b
-1 -1
5 = b
Therefore the y-intercept (b) is 5. (4) The final step is to combine the information into the slope-intercept form; y = -1/3x + 5. Good luck!

A 15-foot ladder is leaning against a building, with the base of the ladder 5 feet from
the building. How high up on the building will the top of the ladder reach?
Answers
Answer:
10√2
Step-by-step explanation:
We can form a triangle with the clues in the question, and use the formula A²+B²=C²
Now, we plug in our values.
5²+B²=15²
25+B²=225
B²=200
B=√200
√200 =√2x2x2x5x5 = 10√2
25+b^2=225
b^2=200
Square root each sides so it would be
b= 10 root 2
b=14.14
So the building is 14.14 feet when the ladder touches it
