Answer:
6.5%
Step-by-step explanation:
You can find the tax rate by finding the percentage that the initial price increased by.
First, subtract the initial price from the price after taxes.
509.07 - 478 = 31.07
Knowing this we can find the tax rate using an equation like this.
[tex]\frac{Difference Between Values}{Initial Value} = \frac{x}{100}[/tex]
Now we substitute in our values.
[tex]\frac{31.07}{478} = \frac{x}{100}[/tex]
With X being the tax rate, we cross multiply both fractions.
3107 = 478x
From here, we solve for x by dividing 3107 by 478.
x = 6.5
Therefore the tax rate is 6.5 percent.
(Note that when you are trying to find the tax rate that you divide by the initial price before taxes to get the correct value.)
Answer:
Step-by-step explanation:
Tax = Total including tax - original price
= 509.07 - 478
= $31.07
Tax rate = [tex]\frac{tax}{original price}*100[/tex]
= [tex]\frac{31.07}{478}*100[/tex]
= 6.5 %

Factorise mx+cx+my+cy
With steps!!!
x=algebra x
Step-by-step explanation:
Hey there!
While factorising you remember to make it take common in most of the expression.
Here;
=mx+cx+my+cy
Take common 'x' in "mx+cx" and 'y' in my + cy.
= x(m+c) + y(m+c)
Now, "(m+c)" common again.
= (m+c) (x+y)
Therefore the factorized form of the expression in (m+c)(x+y).

What does integers have to do with Square Roots?
x-34=xy=78
[tex]\sqrt{x}[/tex] = 91,xy=t
Please Help no dumb answers please. :)
From the examples given it is unclear.
If you know that the square root of some number, x, is 91, you can square 91 to find the value of x.
91² = 8281. Both numbers are integers. 91 can be factored-- 91=7 × 13. Both are prime factors and integers, but not square roots of 91
-34 is an integer, factors could be -2 and 17 or -17 and 2 prime factors and integers. But the square root of -34 is an imaginary number.
78 is not a multiple of -34 so if you are trying to get factors xy of 78 and -34, at least one factor will not be an integer, and the square root is probably irrational-- not an integer.
Maybe confusing, but I'm attempting a sensible discussion of the question.

D. y = (x - 4)^2 + 2
Let f(x) = x^2 + 2x + 4. Which of the following statements is NOT true?
A. f(x) has a maximum value
B. The graph of f is not a line
C. The graph of f has no x-intercepts.
D. The graph of f has a y-intercept.
Answer:
d and a
Step-by-step explanation:
Hi friend
The the equation of the graph obtained is y = [tex](x - 4)^2 +2[/tex] and the NOT true statement is f(x) has a maximum value .
What is translation in graph?A translation is a movement of the graph either horizontally parallel to the axis or vertically parallel to the axis. To move a graph right, we add a negative value to the x-value. To move a graph left, we add a positive value to the x-value.
According to the question
1> The graph of y = [tex](x - 2)^2 - 3[/tex]
translation 5 units up and 2 units to the right
Now,
translation 5 units up that means we have to add +5 to move it up
i.e
y = [tex](x - 2)^2 - 3[/tex] + 5
y = [tex](x - 2)^2 +2[/tex]
Then
translation 2 units to the right
as per translation rules:
To move a graph right, we add a negative value to the x-value. To move a graph left, we add a positive value to the x-value.
i.e
y = [tex](x - 2-2)^2 +2[/tex]
y = [tex](x - 4)^2 +2[/tex]
2>The equation f(x) = [tex]x^2 + 2x + 4[/tex]
Analyzing all the options
Option A : f(x) has a maximum value
This statement is not true as y or f(x) can not be always max or min for all values of (x) .
Option B: The graph of f is not a line
This is true as it is a quadratic equations its graph will be parabola .
Option C: The graph of f has no x-intercepts
This statement is true as x intercepts means y = 0
but it cannot be possible
Option D: The graph of f has a y-intercept.
This statement is true as y intercepts means x = 0
at x= 0
the equation will be
f(x) = [tex]x^2 + 2x + 4[/tex]
f(x) = [tex]4[/tex]
Hence, The the equation of the graph obtained is y = [tex](x - 4)^2 +2[/tex] and the NOT true statement is f(x) has a maximum value .

Answer:
you need to add the seven temperatures up then divide by how many terms there are then you have the mean/average
Step-by-step explanation:
I'm an FLVS student and had this assignment last year. I attached screenshots of my paper so you can see how to answer the questions. Please just dont copy my work word-for-word; you'll get flagged for plagerism by TurnItIn. Just apply the same methods to your own data.
So for the questions in part B, here's what you could say:1. What is the mean change in the forecasted high temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.
Add all the diffrences in high temperature: 0 + 1 + (-2) + 0 + (-5) + 0 = (-6). Then divide the answer, negative six, by the number of days, six: (-6) ÷ 6 = (-1). This shows that the mean change in forecasted high temperature is (-1).
2. What is the mean change in the forecasted low temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the low temperatures. If your answer is not an integer, explain what two integers your answer is between.
Add all the diffrences in low temperature: (-1) + 1 + 0 + 0 + (-7) + (-2) = (-9). Then divide the answer, negative nine, by the number of days, six: (-9) ÷ 6 = (-1.5). Because this answer is not an interger, we will represent the mean by the two interegers it is between. The mean change in forecasted low temperature is between (-2) and (-1).

316x - 2) - 7 = 18x - 13
Answer:
True.
Step-by-step explanation:
Multiply 3 by 6x-2 and you get (18x-6). Subtract 7 from -6 gives you 13, which equals 18x-13.
Answer:
True
Step-by-step explanation:
You want to get the x's by themselves, so first you have to use the distributive property.
3 x 6x = 18x
3 x 2 = 6
So now the equation should look like
18x - 6 - 7 = 18x - 13
So now you have to get the x's by itself by adding or subtracting like terms.
- 6 - 7 = -13
18x - (-13) = 18x - 13
+ (-13) + (-13)
-----------------------
18x = 18x
18/18 18/18
x = 1
Now plug the numbers in
3(6(1) - 2) - 7 = 18(1) - 13

solve - 5x -3 + 4x + 1= -4
Answer:
x = 2
Step-by-step explanation:
Solve for x:
4 x - 5 x - 3 + 1 = -4
Hint: | Group like terms in 4 x - 5 x - 3 + 1.
Grouping like terms, 4 x - 5 x - 3 + 1 = (4 x - 5 x) + (1 - 3):
(4 x - 5 x) + (1 - 3) = -4
Hint: | Combine like terms in 4 x - 5 x.
4 x - 5 x = -x:
-x + (1 - 3) = -4
Hint: | Evaluate 1 - 3.
1 - 3 = -2:
-2 - x = -4
Hint: | Isolate terms with x to the left hand side.
Add 2 to both sides:
(2 - 2) - x = 2 - 4
Hint: | Look for the difference of two identical terms.
2 - 2 = 0:
-x = 2 - 4
Hint: | Evaluate 2 - 4.
2 - 4 = -2:
-x = -2
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of -x = -2 by -1:
(-x)/(-1) = 2
Hint: | Any nonzero number divided by itself is one.
(-1)/(-1) = 1:
