(7TH GRADE MATH) Based on her recipe, Elena knows that 5 servings of granola have 1,750 calories.
Wrote an equation to represent the relationship between the number of calories and the number of servings of granola. (think y=kx)
Answer:
under y is 700 im guessing under the two would be like 1/2 i dont know k
Question 2: A line includes the points (20, 18) and (15, 13). What is its equation in
slope-intercept form?
y =
Answer:y=x
Step-by-step explanation: 13-18=-5
15-20=-5
-5/-5=1 slope
Using point slope take the first point and that slope to find the slope intercept.
Y-18=1(x-20)
Y=x-2
Tammy buys a 4-gigabyte memory card for her camera. Dijonea buys a memory card with twice as much storage as Tammy’s. One gigabyte is 1,024 megabytes. How many megabytes of storage does Dijonea have on her memory card?
Answer:
Dijonea have 8192 megabytes on her memory card
Step-by-step explanation:
Capacity of Tammy's memory card = 4-gigabyte
given that Dijonea buys a memory card with twice as much storage as Tammy’s
Thus,
Capacity of Dijonea's memory card = 2*Capacity of Tammy's memory card
Capacity of Dijonea's memory card = 2*4-gigabyte = 8-gigabyte
Given that
1 gigabyte = 1,024 megabytes
we have to find value of 8 gigabyte in terms of megabytes
for that we multiple both side in above equation by 8
1 *8 gigabyte = 1,024 *8 megabytes
8 gigabyte = 8192 megabytes
Thus, Dijonea have 8192 megabytes on her memory card

Hi I was a little confused on dilation can anyone help me (will mark Brainly)
Just divide the distance of each to point P by 2.
C would be 1 unit above and 2 units to the right of P.
D would be 1 unit below and 2 units to the right of P.
And so on...
Hope this helps

solve the equation. check your solution 6(4-z)=2z
Answer:
3
Step-by-step explanation:
6(4 - z) =2z
24 - 6z =2z
24 =2z +6z
24 =8z
z=24 :8
z=3
Answer:
z=3
Step-by-step explanation:
6(4-z)=2z
24-6z=2z
24=2z+6z
24=8z
z=3

Given 28-6x=2x-84 prove x=14.
Answer:
-56
Step-by-step explanation:
substitute x with 14 in the equation and both answers will be -56
28-6x = 2x -84
Add 6x to both sides:
28 = 8x -84
Add 84 to both sides
112 = 8x
Divide both sides by 8
X = 112/8
X = 14

The prices for different lengths of ribbon sold at a fabric store are shown in the table.
Which statement BEST justifies whether or not the relationship between the length and price represents a function?
A.
This relationship does not represent a function because it relates inches and dollars.
B.
This relationship represents a function because no length of ribbon has more than one price.
C.
This relationship represents a function because the price per inch decreases as the length of ribbon increases.
D.
This relationship does not represent a function because the prices of different lengths of ribbon are all different.
Answer:
B. This relationship represents a function because no length of ribbon has more than one price.
Step-by-step explanation:
A relation is considered as a function when there is exactly just one possible range value that any of the domain value can give. In order words, each domain value of a function cannot have more than one range value.
In the given table of values representing the length and price of ribbon, the domain includes all the set of lengths of the ribbon while the range is the set of the corresponding prices the lengths can cost.
Thus, each length given has exactly just one price. No particular length has more than one price. Therefore, we can consider this as a function.
A local pizza shop has a membership program for frequent buyers. The membership costs $10 per month and members get a discounted price of $1.75 per slice of pizza. Autumn purchased a membership to this pizza shop.What would be the monthly cost for xx slices of pizza?
Answer:
Monthly cost = $10 + $1.75x
Step-by-step explanation:
Given the following :
Membership cost = $10 per month
Discounted price for members = $1.75 per slice of pizza
If Autum purchased the membership, the monthly cost for x slices of pizza
Monthly cost of x slices will be :
Membership cost + (discounted price * number of slices)
Monthly cost = $10 + ($1.75 * x)
Monthly cost = $10 + $1.75x
Jenny is making tie dyed shirts for her class with her school colors, blue and yellow she used a total of 8 ounces of fabric paint the amount of blue paint is 3 times the amount of yellow make a diagram to show the ratio of blue to yellow paint
Answer:
The ratio of blue paint to yellow paint is 3:1
Step-by-step explanation:
Let
x -----> the amount of blue paint in ounces
y ----> the amount of yellow paint in ounces
we know that
x+y=8 -----> equation A
x=3y -----> equation B
Solve the system by substitution
Substitute equation B in equation A
3y + y = 8
4y = 8
y = 2
Find the value of x
x = 3(2) = 6
therefore
The amount of blue paint is 6 ounces and the amount of yellow paint is 2 ounces
Find the ratio
To find out the ratio of blue paint to yellow paint, divide the amount of blue paint by the amount of yellow paint
x/y = 6/2 = 3/1
That means -----> Of every 4 parts of paint, three parts are blue and one part is yellow.
the question is Reasoning Determine whether each statement is true or false for f (x) = |x|,
and explain your answer.
2. False -3 is not in the range of the function because the absolute value bars limit the y value to 0 and above
3. True any function like this with the x value in absolute value bars will always be identical on the opposite side of the y-axis
this applies to anything like: y=|x|, y=2|x|, y=|2x+2| and y=|x|+2

The perimeter of the triangle below is 4x + 3y. Find the measure
of the missing side.
Answer:
2x + 3y
Step-by-step explanation:
first you add the two known sides: (x-y)+(x+y) = 2x
Then you subtract the answer (2x) from the total perimiter (4x+3y) :
4x+3y-2x = (4x - 2x) + 3y = 2x + 3y
