Get the slope of the line using the two known points:
slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3
Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,
y - 6 1/4 = 3 (x - 3/4) ⇒ y = 3x + 16/4 = 3x + 4
Then for some given value of x, the third point has y-coordinate 3x + 4.
"Which values" suggests there may be more to the question, namely some list of answer choices. If you have something like that, just check if the above condition is met.

Step-by-step explanation:
This is an example of correlation because there is an obvious relationship between the two scenarios.
This is an example of correlation because there is an obvious relationship between the two scenarios. The correct option is A.
What is a correlation?The statement "when more apples grew in the backyard, the pet cat stayed indoors for a longer time" is an excellent example to explain the difference between causation and correlation.
Is the very fact that the apples grew in the backyard what makes the pet cat stay indoors longer?
Sure, you know it isn't. sure there is another cause that influences both the growing of apples and the time the pet cats stay indoors. So, there is no causality relationship.
Given that some fact is influencing both phenomena, you find that they behave in a way that one permits predict the other, which is what correlation indicates, but not that one is the cause of the other.
When you know the cause you might change the final behaviour, but when you know that the variables are correlated you just can use one to predict the other.
Therefore, this is an example of correlation because there is an obvious relationship between the two scenarios. The correct option is A.

Answer:
1st question is D, 2nd question is G, 3rd is D
Step-by-step explanation:
1st, It says plus the cost of s, so you can mark out every other one except D because it says plus, you don't multiply it with the cost of the cheeseburgers. 2nd, For the next one all you have to do is subtract each number on the top by 12. Like 2 - 12 = -10, 4 - 12 = 8, and etc. Since the others don't have that like 1 - 12 does not equal -12 like it says in J. Also unlike F none of the answers can be positive, and in H it is basically adding the numbers instead of subtracting and putting a negative sign in front. Therefore G is the answer for 2. 3rd, because for every mile it costs 2.50 so that's the relationship between the table. Basically since every mile costs 2.50, you multiply 2.50 by the distance. Which if you do the inverse is the cost = distance divided by 2.5.

Answer: it's wrong

reason: this'll help you know how to turn it into a fraction.
Chosen possibility of an action
over (or fraction bar)
total amount of possibilities
so now that you know why, now we find out the possibilities of rolling an odd and even numbers between 1 and 6.
1, 3, 5 = 3/6 = 1/2
2, 4, 6 = 3/6 = 1/2
which means there is 1/2 chance of getting either an even or an odd. so they are incorrect because they are as likely as to not likely to be rolled on.
Answer: they are wrong
Step-by-step explanation: there is 6 sides of a die, so there is a 1/6 percent chance and number between 1 and 6
1, 3, 5 = 3/6 = 1/2 = 50%
2, 4, 6 = 3/6 = 1/2+= 50%

Reuben is making a replica of the US flag for his school project.
He uses a scale of 0.5 centimeter to 1 inch to draw the flag. The length of the scale drawing is 2.5 centimeters, and its width is 4.75 centimeters.
The perimeter of the scale drawing is
centimeters.
The perimeter of the actual flag is
inches.
Answers
Answer:
14.5 cm, 29 in.
Step-by-step explanation
The perimeter(P) is 2L+ 2W, so P = 2 * 4.75 + 2 * 2.5 = 14.5.
Double 14.5, because every 0.5 cm is 1 inch. 14.5 * 2 = 29.

1) If y is the amount of dog food in the bin, and x is the number of days the dogs have been fed, write an equation to represent the amount of food left in the old dog's bin.
You are pet sitting your neighbor's dogs for a couple of weeks. Each dog must be fed a different type of food. The instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. The puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. Use your system of equations to calculate the number of days until both containers have the same weight of food in them.
2)If y is the amount of dog food in the bin, and x is the number of days the dogs have been fed, write an equation to represent the amount of food left in the puppy's bin.
3)Use your equations to solve to find the number of days when both containers will have the same weight of food in them. (check your solution!)
Answers
The equation computed shows that the number of days until both containers have the same weight of food in them will be 12 days.
How to calculate the equations?From the information given, the instructions say to feed the old dog 2/3 pound of food each day from the bin with 25 lbs of kibble in it. the equation will be:
= 25 + 2/3d
= 25 + 0.67d
Also, the puppy is to get 1/4 pound of food each day from the bag with 20 lbs of puppy kibble in it. This will be:
= 20 + 1/4d
= 20 + 0.25d
The number of days until both containers have the same weight of food in them will be:
25 + 0.67d = 20 + 0.25d
0.67d - 0.25d = 20 - 25
0.42d = 5
d = 5/0.42
d = 11.9
d = 12 days

Mrs. Hanger is painting the following picture of an H to hang in the entryway of her home. She has made the following scale drawing as her model. The scale used on the drawing is 1:6.
As you can see, the "H" is going to be painted brick red in the center of a rectangular beige background. This means the distance from the "H" to the top of the picture will be the same as the distance from the "H" to the bottom of the picture. Similarly, the distance from the "H" to the left side of the picture will be the same as the distance from the "H" to the right side of the picture. Finally, each segment of the "H" will have the same width.

What are the dimensions of the painting on the new scale drawing?
Answers
Answer:
5 in. by 4 in.
Step-by-step explanation:
The proportion of 1/4 is larger than 1/6 so the new scale drawing is larger. The new scale drawing is the drawn blank. The dimensions are 5 in. x 4 in. for the background. The H's dimensions are 1/2 in. width and also 1 in. The height is about 4 in. Length, width and height are all dimensions which is what I was trying to find.

The Smith family went to eat at Buffalo Wild Wings. The bill was $43.86. They gave the server a 20% tip. How much did they pay altogether?
Answers
$52.63
Step-by-step explanation:To find 20% of $43.86 we multiply $43.86 by 0.2
$43.86 • 0.2 = $8.772
Now add $43.86 and $8.772 to find out how much the family paid altogether.
$43.86 + $8.772 = $52.632
In money the smallest place value is cents so we have to round to the hundredths place.
Doing this we get the grand answer of:
$52.63
To find the altogether cost of the meal including tip you need to multiply the bill ($43.86) by 1.20
43.86(1.2) = 52.632
Same would go for if you were leaving a 10% tip but you would multiply by 1.10
8th grade word problem, show steps please (will give brainiest) :)
Answers
Answer:
There are 24 students and teachers that rode in vans, and there are 385 students and teachers that rode in buses.
Step-by-step explanation:
First we are going to set up a system of equations where:
b= number of buses
v= number of vans
We know from the equation that each bus transported 55 people and that each van transported 12 people and that there was a total of 409 people transported. We also know that the number of buses was 5 more than the number of vans.
Knowing that we can set up our system:
[tex]\left \{ {{55b+12v=409} \atop {b=v+5\\}} \right.[/tex]
Since we know what b is equal to, we can now use the substitution method to plug the value of b from the bottom equation into the one on the top and solve for variable v.
55(v +5)+12v =409
From there we can distribute 55 into (v+5)
55v +275+12v =409
We can now combine like terms.
67v +275 = 409
From there we subtract 275 from both sides of the equation to isolate the variable.
67v +275 = 409
-275 -275
After doing this, we now divide both sides of the equation by 67 to solve for v.
[tex]\frac{67v}{67} =\frac{134}{67}[/tex]
We now know that v, the number of vans is 2 and can plug that into our bottom equation from our system of equations ([tex]b=v+5[/tex]).
[tex]b=2+5\\b=7[/tex]
Knowing that there are 7 buses and 2 vans, we can now plug these numbers into the terms in the top equation of our system. 55b and 12v.
[tex]55(7)=385[/tex]
[tex]12(2)= 24\\[/tex]
385 people rode buses. 24 people rode vans
Check your equation
409 people went in total. 385 + 24 = 409.
