3) x=6
Step-by-step explanation:
to get y, divide x by 2. to get x, multiply y by 2
Can someone explain to me an easy way to divide fractions? I can't seem to understand it.
Answer:
Flip the second fraction and multiply across
ex: 5/4 divided by 3/6
5/4 * 6/3
5*6 / 4*3 = 30/12
5/4 divided by 3/6 = 30/12

Step-by-step explanation:
Consider the line 7x+9y=5
what is the slope of a line parallel to this line?
what is the slope of a line perpendicular to this line?
Answer:
The slope of a line parallel to this line will be: -7/9
The slope of the perpendicular line will be:
[tex]\frac{-1}{\frac{-7}{9}}=\frac{9}{7}[/tex]
Step-by-step explanation:
We know the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope b is the y-interceptGiven the equation
[tex]7x+9y=5[/tex]
simplifying to write in the lope-intercept form
[tex]y=-\frac{7}{9}x+\frac{5}{9}[/tex]
Thus, the slope of the line is: -7/9
The slope of a line parallel to the line:
We have already determined that the slope of the line is: -7/9
We know that the parallel lines have the same slope.Thus, the slope of a line parallel to this line will be: -7/9
The slope of a line perpendicular to the line:
We have already determined that the slope of the line is: -7/9
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus, the slope of the perpendicular line will be:
[tex]\frac{-1}{\frac{-7}{9}}=\frac{9}{7}[/tex]

please help me asap!!
Answer:
28/3
Step-by-step explanation:
We see that the triangles are simalar to eachother, so we can set up this ratio:
x/(8+x) = 7/13
x = 56/13 + 7x/13
13x = 56 + 7x
6x = 56
x=56/6=28/3

Answer:
A. y=[tex]\frac{3}{2}[/tex]x-3
B.y=[tex]\frac{-3}{4}[/tex]x-3
Step-by-step explanation:
Okay so essentially, the first thing you need to do is find the slope and y intercept for each equation. To find the slope, I like to look at the two points and divide the rise (How much it goes up or down) by the run (How much it moves left or right). For A the rise is 6 and the run is 4, so the slope is 6/4 or 3/2. To find the equation for A, you also need the y-intercept which is just the y value (how high up or down) it is when it crosses the y axis. In graph a, this is at -3. Because the equation of a line is y=mx+b (m being slope and b being y intercept), we know the equation for a is y=[tex]\frac{3}{2}[/tex]x-3. We can do the same thing for B. The rise is -3 and the run is 4, so the slope is -3/4. The y value when x is equal to zero is 2, so that is the y intercept. The equation is y=[tex]\frac{-3}{4}[/tex]x-3
slope intercept form
through: (2, 4) and (1, -3)
Answer: I attached a graph below, hope it helps.
Step-by-step explanation:
A line can be written in the form y = mx + b where m is the slope and b is the y intercept.
Since the slope is given as 4, the equation will be y = 4x + b
Plugging in the point (2,1) to the equation we get 1 = 4(2) + b or 1 = b + 8
Solving for b gives b = -7 so the equation will be y = 4x - 7
In ΔHIJ, the measure of ∠J=90°, the measure of ∠H=71°, and JH = 2 feet. Find the length of IJ to the nearest tenth of a foot.
Answer:
IJ is 5.8 ft
Step-by-step explanation:
Here, we want to calculate the length of IJ
to Find IJ, we need the appropriate trigonometric ratio
The trigonometric ratio to use in this case is the one that connects the opposite and the adjacent
from the question, IJ is the opposite
This is the side facing the given angle
HI is the hypotenuse which is the side facing the right-angle
HJ is the third side which is the adjacent
Mathematically;
That is the Tan
Tan 71 = IJ/2
IJ = 2 Tan 71
IJ = 5.8

Three different coins are tossed. What is P(tail, head or tail, head, or tail)
Answers:
Probability of landing all three coins on head: [tex]\frac{1}{8}[/tex]
Probability of landing all three coins on tail: [tex]\frac{1}{8}[/tex]
Probability of landing two coins on head and one on tail: [tex]\frac{3}{8}[/tex]
Probability of landing two coins on tails and one on head: [tex]\frac{3}{8}[/tex]
Step-by-step explanation (Read Carefully):
-How to calculate this is that there are three possible outcomes when tossing the three coins. So, if you group all the possible outcomes of heads and tails when tossing the three coins in one event, you’ll get eight events. Let’s take a look at it:
-A way to organize this is to have:
H = heads
T = tails
-Total of eight events, where each event is the probability of the three coins being tossed (possible events with equal probability, and order matters):
HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
Now, let’s apply some questions:
⇒ Probability of landing all three coins on heads: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on heads? Well, you can see that there is only one possible event that has HHH. So, the probability of landing all three coins on heads (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing all three coins on tails: [tex]\frac{1}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) that all three coins land on tails? Well, you can see that there is only one possible event that has TTT. So, the probability of landing all three coins on tails (out of the eight events) is [tex]\frac{1}{8}[/tex].
⇒ Probability of landing two coins on heads and one on tails: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on heads and one on tails? Well, you can see that there are three possible events that include HHT, HTH, THH. So, the probability of landing two coins on heads and one on tails (out of the eight events) is [tex]\frac{3}{8}[/tex].
⇒ Probability of landing two coins on tails and one on heads: [tex]\frac{3}{8}[/tex]
Explanation: Look at the events above. How many times (out of the eight events) where two coins land on tails the one on heads? Well, you can see that there are three possible events that include HTT, THT, TTH. So, the probability of landing two coins on tails and one on heads (out of the eight events) is [tex]\frac{3}{8}[/tex].

Step-by-step explanation:
In a high school, 28% of the school’s population is seventeen years old. Of the students who are seventeen years old, 44% play a sport. One student at the high school is chosen at random to represent the school at a community event. What is the probability that the selected student will be seventeen years old and not play a sport?
Answer:
15.68%
Step-by-step
Since 44% of the 28% play sport subtract 44 from 100 to see how many of the 28% do not play sports and you get 56%. So multiply 56% and 28% and you get 15.68%.

Find the value of X
Show work
Look at the picture for the question.
Answer:
Option D: the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab.
Step-by-step explanation:
We are told that his monthly profit is given by the relation;
P = 32.5x - 845
Where x is number of pictures he needs.
We want to find what the x - intercept represents.
x intercept means that the y-value at that point is zero.
Thus, x-intercept means the profit is 0.
If profit is zero, it means his cost of operating his photography lab each month is equal to the amount of photographs he is able to sell.
Thus, it means that the x-intercept represents the minimum amount of photographs he must sell to pay for his photography lab monthly.

The local water supply has a leak, it is losing 4 gallons of water every second.
After 15 seconds, the water level is at 1024 gallons. Write an equation to
represent the situation: *
Answer:
An equation to represent the situation would be:
[tex]y = 4x + 964[/tex]Step-by-step explanation:
Given that the water supply is losing 4 gallons of water every second.
It means the rate of change = 4 gallons per second
Given that after 15 seconds, the water level is at 1024 gallons.So the equation becomes
1024 = 4(15) + b
comparing with the slope-intercept form of the equation of a line
[tex]y = mx+b[/tex]
where m is the slope (rate of change) and b is the y-intercept
so
[tex]1024 = 4(15) + b[/tex]
[tex]1024 = 60 + b[/tex]
[tex]1024 - 60 = b[/tex]
[tex]b = 964[/tex]
So, the value of y-intercept i.e b=964
Thus, the equation will be
[tex]y = mx+b[/tex]
substituting the value rate of change i.e m = 4 and b=964
[tex]y = 4x + 964[/tex]
Therefore, an equation to represent the situation would be:
[tex]y = 4x + 964[/tex]Simplify.

Why can't you have a shoe size of 4.5 and a height of 72 inches?
Answer:
Ok, lemme say something.
4.5 shoes are for 9 inch feet.
Dont think a 6 foot person is gonna fit tbh.
Step-by-step explanation:
A shoe size is for relation to feet size. Your feet grow from your height too, along with weight. If you are 6 feet, your feet are gonna be more than at least 1 foot.
4.5 shoes are for 9 inch feet
1 foot = 12 inches.
12 > 9.
12-9=3.
