Step-by-step explanation: 569.99 * 30%=171.
569.99-171.=398.99
398.99*15% = 59.85

Left 3. Up 4
Down 3. Right 4
O Up 3 Right 4
Answer:
3 down, 4 up
Step-by-step explanation:
-3 is the X line, which starts on 0, if you subtract 3, or add -3, you would have to go down, 3 down. 4 is on the Y line, so you add, go left to add on the Y line, 4 up.
Always start with you X coordinate. Here is a tip to help you (X, Y)
Is it a function? Explain
Answer:
Yes.
Step-by-step explanation:
For a graph to be a function, it must have precisely one y-value for every x-value.
In this case, this graph is a function because it meets the requirements of having one y-value for every x-value.

Show work Plss oooooooo
Answer:
22.5 mins
Step-by-step explanation:
To find what that video's length must be, subtract the previous videos' lengths from the requirement, 5 hours. (x is the video length of her fourth video)
7/8 + 1 1/4 + 2 1/2 + x = 5
To make adding these fractions easier, find a common denominator.
7/8 + 1 2/8 + 2 4/8 + x = 5
4 5/8 + x = 5
x = 3/8, or 22.5 minutes.
Answer:
[tex]\frac{3}{8} \text{ hours.}[/tex]
Step-by-step explanation:
Her first three videos totalled up to
[tex]\frac{7}{8} + 1\frac{1}{4} + 2\frac{1}{2}\\=\frac{7}{8} + \frac{5}{4} + \frac{5}{2}\\=\frac{7}{8} + \frac{5}{4} \cdot \frac{2}{2} + \frac{5}{2} \cdot \frac{4}{4}\\=\frac{7}{8} + \frac{10}{8} + \frac{20}{8}\\=\frac{7+10+20}{8}\\=\frac{37}{8}[/tex]hours. To meet the [tex]5 = \frac{40}{8}[/tex] hour goal the shortest fouth video she can make is [tex]\frac{40}{8} - \frac{37}{8} = \frac{3}{8}[/tex] hours, because if the fourth video was any shorter, she'd end up with less than [tex]\frac{37}{8} + \frac{3}{8} = \frac{40}{8} = 5[/tex] hours in total (this is called a proof by contradiction). We are now done.

What is 5x - 3y when x equals negative 2 and Y equals 6
Answer:
-28
Step-by-step explanation:
We have the equation [tex]5x-3y[/tex] and are given that [tex]x=-2, y=6[/tex]. To solve this equation, we simply replace the variables with their real value. In action, this would be [tex]5(-2)-3(6)=-10-18=-28[/tex].

The greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.
What is LCM?It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that:
The GCF of 14x and 18xy
As we know, GCF is the greatest common factor.
The greatest common factor of 14 and 18 or
GCF(14, 18) = 2
And the greatest common factor of GCF of x and xy
= x
the greatest common factor of 14x and 18xy is:
= 2x
Thus, the greatest common factor of 14x and 18xy is 2x if the numbers are 14x and 18xy.

What is the Area of 28in circle rounded to the nearest hundred
Answer:
The circumference is similar to the perimeter in that it is the total length needed to draw the circle.
We note the circumference as c.
c = 2πr
or
c = πd
This depends on whether or not you know the radius (r) or the diameter (d)
Let’s calculate one manually, for example.
If r = 6 cm, then the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.
Suppose you only know the diameter? If the diameter is 8 cm, then the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth.
