Answer:
(c) r units right
Step-by-step explanation:
The translation transformations are ...
g(x) = f(x -h) +k . . . . . . . shifts h units right and k units up
Your transformation has h=r and k=0, so the graph is shifted r units right and no units vertically.
_____
Additional comment
This in not terribly mysterious. Suppose you have f(1) = 6. This means the point (1, 6) is on the graph.
Now, suppose you transform this to ...
g(x) = f(x -2)
When the value of x is 3, the value of g(x) is f(3-2) = f(1) = 6. That means the point (3, 6) is on the graph of g(x).
It is the same as the point (1, 6) on the graph of f(x), but shifted 2 units to the right.
__
You can shift a function r units right by replacing x with (x-r), as we just discussed. You can shift a function u units up by replacing y with (y-u). When we write equations in "functional form", the "u" gets "moved."
y-u = f(x) . . . . . graph of f(x) shifted u units up
y = f(x) +u . . . . graph of f(x) shifted u units up. (u added to both sides of the above equation)
Please Factor -5x²+13x+6
Answer:
[tex](x-3)(-5x-2)[/tex]
or [tex]-(x-3)(5x+2)[/tex]
Step-by-step explanation:
quadratic equation format: [tex]a^2+b^2+c[/tex]
Therefore, for [tex]-5x^2+13x+6[/tex], a = -5, b = 13 and c = 6
Multiply the coefficient of [tex]x^2[/tex] ([tex]a[/tex]) by the constant term ([tex]c[/tex])
[tex]\implies -5 \times 6 = -30[/tex]
Find two numbers which have a product of -30 and a sum of [tex]b[/tex] (13)
Factors of 30: 1 and 30, 2 and 15, 3 and 10, 5 and 6
So -2 and 15 have a product of -30 and sum of 13.
Rewrite [tex]13x[/tex] as [tex]15x-2x[/tex] and substitute into the equation:
[tex]\implies -5x^2+15x-2x+6[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies-5x(x-3)-2(x-3)[/tex]
The bracket created should always be the same.
The two brackets have now been found. The first bracket is the common factor of (x - 3). The second bracket is the factorized terms outside of each bracket (-5x - 2).
[tex]\implies (x-3)(-5x-2)[/tex]
Additionally, we can write (-5x - 2) as -(5x + 2)
[tex]\implies -(x-3)(5x+2)[/tex]
Select the expressions that are equivalent to 2q + 8q.
q • 10
10q
q +9q
q + q+ 8q
Answer:
10qq +9qq + q+ 8qStep-by-step explanation:
We know that, when combining 2q + 8q we'll get → 10q
1) q • 10 (Nope)
2) 10q (yes, It's equivalent)
3) q +9q (combine) → 10q (yes, It's equivalent)
4) q + q+ 8q (combine) → 10q ( yes, It's equivalent)
So therefore, 10q , q +9q, q + q+ 8q are expressions equivalent to 2q + 8q..

Using the unpaid balance method, find the current months finance charge on a credit card account having the following transactions.
Last month’s balance: $385
Last payment: $250
Annual interest rate: 21%
Purchases: $303
Returns: $158
(It would be great if you could tell me how to use the formula I=Prt where previous months balance + finance charge + purchases made - returns - payments)
Answer:
$5.02
Step-by-step explanation:
The unpaid balance method is a common method used by credit card companies to calculate finance charges. It determines the finance charge based on a portion of the previous balance you have not yet paid.
Equations to use:
[tex]\boxed{\begin{minipage}{9.7cm}\phantom{w}\\Periodic (monthly) rate = annual interest rate $\div$ 12\\\\Finance Charge = previous balance $\times$ periodic rate\\\\Unpaid Balance = previous balance + finance charge +\\\phantom{wwwwwwwwwww} new purchases - returns - payments\\\end{minipage}}[/tex]
The periodic rate is the interest rate charged over a certain number of time periods. The interest on a credit card is usually calculated monthly, so if the annual interest rate is 21%, then the periodic (monthly) rate is:
[tex]\text{Periodic Rate}=\dfrac{21\%}{12}=1.75\%=0.0175[/tex]
The unpaid balance is "last month's balance", which is $385.
Calculate the finance change by multiplying the previous balance (last month's balance) by the periodic rate:
[tex]\begin{aligned}\text{Finance change} &=\rm previous\; balance \times periodic\;rate \\&=\$385 \times 0.0175 \\&= \$6.7375\end{aligned}[/tex]
Calculate the unpaid balance by subtracting the returns and payments from the sum of the previous balance, finance charge and new purchases:
[tex]\begin{aligned}\rm Unpaid \; Balance &= \rm previous\; balance + finance\;charge +new \;purchases\\&\phantom{=w}\rm - returns - payments\\&= \$385 + \$6.7375 + \$303 - \$158 - \$250 \\&= \$286.7375\end{aligned}[/tex]
Finally, to calculate the current month's finance charge, multiply the unpaid balance by the periodic rate:
[tex]\begin{aligned}\text{Current month's finance charge}&=\rm unpaid \;balance\times periodic \;rate\\&=\$286.7375 \times 0.0175 \\&= \$5.02\; \text{(nearest cent)}\end{aligned}[/tex]
Therefore, the current month's finance charge is $5.02 to the nearest cent.

If 600 people were surveyed in order to make this pie chart, how many people say they take the bus? 20 points
Answer:
if 600 people were surveyed it means that 10% equals 60 since 60x10=600. Since we now know that 10% is 60, this would mean that 20% is 120. meaning that 120 people took the bus

sophia has 7m of ribbon to help decorate a room. she will cut pieces of ribbon that are each r inches long. (1in.=2.54cm) which expression can help find the number of pieces of ribbon that she will have
Step-by-step explanation:
1 m (meter) is 100 cm (centimeters).
so, 7 m is 700 cm.
each piece is r × 2.54 cm long (as every inch is 2.54 cm).
so,
number of pieces = 700 / (r × 2.54)
The number of species can find by expression is
700 / (r × 2.54)
We have given that

Mai got a prepaid debit card with 30 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 23 cents per yard. If after that purchase there was 27.01 left on the card, how many yards of ribbon did Mai buy?
Answer:
The answer I got was 13.
Step-by-step explanation:
I first did 30-27.01 to get 2.99.
I then divided 2.99 by 0.23 or 2.99/0.23 to get 13.
