Athena bought x boxes of cookies to bring to a party. Each box contains 10 cookies. She decides to keep two boxes for herself. She brings 70 cookies to the party. Which equation can be used to find the number of boxes, x, Athena bought?
Given parameters:
Number of boxes Athena bought for the party = x
Number of cookies per box = 10
Number of cookies she brought to the party = 70
Number removed = 2 boxes
Unknown:
Equation of the number of boxes = ?
Solution:
1 box of cookies contains 10 cookies
If Athena, removed 2 boxes, in those two boxes, we have 20 cookies
Total number of cookies = 70 + 20 = 90 cookies;
So;
x = [tex]\frac{total number of cookies}{number of cookies per box}[/tex]
Therefore;
x = [tex]\frac{90}{10}[/tex]boxes

What is the range of the function f (x)= 4x -6 when the domain is { -4,-2,0,2,6}?
Answer:
{-22, -14, -6, 2, 18}
Step-by-step explanation:
f(-4)=4(-4)-6=-22
f(-2)=4(-2)-6=-14
f(0)=4(0)-6=-6
f(2)=4(2)-6=2
f(6)=4(6)-6=18

Your answer
solve for y
Answer:
y=-2+x/3 OR y=x/3-2
Step-by-step explanation:
x-3y=6
minus x from each side
-3y=6-x
change the symbols
3y=-6+x
divide by 3
y=-2+x/3
if you want, you can make it look better by switching it around to:
y=x/3 -2

A 1st degree polynomial function whose graph intercepts the y-axis at 8.
Your answer can be anything in the form y = mx+8 where you replace m with any real number.
You start with y = mx+b, and then replace the b with the y intercept 8.
The y intercept is where the polynomial crosses the y axis.
The value of m does not matter. So you could have y = 2x+8 or y = 3x+8 for instance. Replace m with whatever your favorite number is.
We want to find a polynomial of 1st degree that passes through the y-axis at y = 8.
The polynomial is: y = a*x + 8
Where the coefficient a can be any real number different than zero.
Let's see how to find that polynomial.
Remember that the degree of a polynomial gives us information of the maximum exponent that the polynomial has.
So if the degree is 1, then the polynomial maximum exponent is 1.
From this we can conclude that the polynomial will be something like:
y = a*x + b
Now, this is just a linear equation, where a is the slope and b is the y-intercept.
We do know that this intercepts the y-axis at 8, then we define b = 8, and we get:
y = a*x + 8
This is our polynomial, where the value of a can be any real number different than zero (we use that restriction because if a = 0, then the degree of the polynomial would not be 1).

In math class, you have the following scores: 77, 82, and 73. If the
last test has a maximum of 100 points, what score do you need for
an average of 80?
Answer: 88
Step-by-step explanation: 77+82+73= 232. So you need an 80 for average. So what you have to do is 80x4 and that equals to 320. last step is to subtract 320-232 and you get 88. 77+82+73+88=320.
Answer:
Did you actually get that score???
Actually, it is none- of my buisness, but no one will judge
and probably not for the 77 and 73 your grade just go's up 2 points if you get a 100

Give the domain and range.
The domain is:
The range is:
Answer:
Domain: (-4,4)
Range: (-4,6)
Step-by-step explanation:
Domain is found by viewing the distance from the points on the x-axis (left to right)
Range is found by viewing the distance from the points on the y-axis (up and down)
For domain, the furthest point on the left is (-4,3). You have to take the x from that furthest to the left point (which is -4) to get the first x in the domain (x,y). The furthest point to the right is (4,6). The x on that furthest point is 4. Put them together in the (x,y) form with the furthest left being x and the furthest right being y. That makes the domain (-4,4).
Same goes for range but instead of it being left to right it will be down and up.
Highest point is (4,6)
Lowest point is (0,-4)
Take the y from each one and put them in (x,y) form, this would make your range (6,-4).
Always put the lowest one first (bottom to top)
Always put the furthest to the left first (left to right)
The (x,y) point for either domain or range will always be (lowest value, highest value). In other words, (lowest number, highest number).
Candace ate 3 over 4 cup of cereal. The box of cereal states that one serving of cereal is equal to 2 over 3 cup. Which fraction represents the number of servings Candace ate?
Answer: Candace ate [tex]\dfrac9{12}[/tex] servings.
Step-by-step explanation:
Given: Candace ate [tex]\dfrac34[/tex] cup of cereal.
The box of cereal states that 1 serving of cereal = [tex]\dfrac23[/tex] cup.
i.e. 1 cup = [tex]\dfrac32[/tex] servings [Multiply [tex]\dfrac32[/tex] both sides]
⇒ [tex]\dfrac{3}{4}[/tex] cup = [tex]\dfrac34\times\dfrac32[/tex] servings
= [tex]\dfrac9{12}[/tex] servings [which is the number of servings she ate]
Hence, Candace ate [tex]\dfrac9{12}[/tex] servings.
