which of the following best describes the effect of replacing the graph of y = f(x) with the graph of y= f(x) - 9? a. the graph of y = f(x) will shift up 9 units b. the graph of y = f(x) will shift down 9 units c. the graph of y = f(x) will shift left 9 units d. the graph of y = f(x) will shift right 9 units

Answers

Answer 1
Answer:

Answer:

B

Step-by-step explanation:

If you were to have an equation y = x.

Then, x - 9 shifts it down 9.

If you were to have an equation y = 2x.

Then, 2x - 9 shifts it down 9.

Using this pattern, we deduce that  f(x) - 9, shifts the graph down 9 units.

So, our answer is B>

Simon is making wreaths to sell your 60 bucks 36 roses and 48 silk carnation do you want to percent number of items on each with all the items on a wreath will be the same type how many items can Simon put on each wreath?

Answers

Answer: 12 Wreaths

Explanation:

If he wants to have the same amount of each item on the wreaths, we need to find the factors of each to find the highest amount of wreaths he can make.

60=2×2×3×5=(2×2×3)×5

36=2×2×3×3=(2×2×3)×3

48=2×2×2×2×3=(2×2×3)×2×2

So, 2×2×3 is in each which is equal to 12 so he can make 12 wreaths with the amount and factor on each wreath below:

12 wreaths

5 bows on each

3 silk roses each

4 silk carnations each

Hope this helps! :)

What is the difference between rational exponents and integer exponents? Select one: a. There is no difference. b. Rational exponents are whole numbers and integer exponents are fractional exponents. c. Rational exponents are fractional exponents and integer exponents are whole numbers. d. Integer exponents are always positive while rational exponents are negative and positive.

Answers

The correct answer is Option (C) Rational exponents are fractional exponents and integer exponents are whole numbers

What is Rational Exponents?

  • Rational exponents aresimplya fraction representing an exponent that is rewritten as a radical expression.

What is Integer Exponents?

  • The exponents containing an integer is Known as Integer Exponents.

What is difference between Rational exponents and integer exponents?

  • Integer means Whole numbers whereas Rational means fraction with whole numbers
  • Hence Rational exponents and integerexponents both contains whole number but rational exponents contains fraction with whole numbers

Hence the correct option is (C)  Rational exponents are fractional exponents and integer exponents are whole numbers

#SPJ2

Answer:

The answer is A

Step-by-step explanation:

What is 90% of 81?
X

Answers

Answer:

72.9

Step-by-step explanation:

Fractions method:

81*(90)/(100) because 90/100 is the same thing as 90%

That gives us 7290/100, from 81*90/100

Simplify: =729/10 = 72.9

Decimals method:

81*9 = 729, add in decimal and that's 72.9

Cross-multiplication:

90    100

?         81

This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.

This is my first answer , hope it helped!

The probability that a city bus is ready for service when needed is 77%. The probability that a city bus is ready for service and has a working radio is 65%. Find the probability that a bus chosen at random has a working radio given that it is ready for service. Round to the nearest tenth of a percent. (Hint: Divide)

Answers

Answer:

0.84

Step-by-step explanation:

Let the probability that a city bus is ready for service when needed is represented as P(ready)=77%=0.77

Let the probability that a city bus is ready for service and has a working radio be represented as P(ready and radio)=65%=0.65

probabilty that it has a working radio given that it is ready for service =

P(radio and ready)=P(ready and radio) ÷  P(ready)

=0.65÷0.77=0.84416

≈0.84 to the nearest tenth

10 + X/3 = 13 what does The X Equal to?

Answers

Answer:

  • X = 9

Step-by-step explanation:

In this question we have provided an equation that is 10+X/3 =13. And we're asked to find the value ofX .

Solution:-

\longmapsto \qquad \: 10 + (X)/(3) = 13

Step 1: Multiplying with 3 on both sides :

\longmapsto \qquad \:(10 + (X)/(3) ) * 3=13*3

Now by using distributive property multiplying 3 with 10 as well as X/3 :

\longmapsto \qquad \: (10 * 3) + ( \frac{X}{ \cancel{3}} * \cancel{3}) = 13 * 3

On calculating further , We get :

\longmapsto \qquad \: 30 + X = 39

Step 2: Subtracting with 30 on both sides :

\longmapsto \qquad \: \cancel{30} + X - \cancel{30} = 39 - 30

On calculating further , We get :

\longmapsto \qquad \: \purple {\underline{{\boxed{\frak{X= 9}}}}}

  • Henceforth,value ofX is9.

Verifying:-

Now we are checking whether our answer is correct or wrong by substituting values of x in given equation . So ,

  • 10 + X/3 = 13

  • 10 + 9/3 = 13

  • 10 + 3 = 13

  • 13 = 13

  • L.H.S = R.H.S

  • Hence , Verified .

Therefore,our value for x is correct.

  • Answer:

\Large{\boxed{\sf x = 9}}

\n

  • Explanation:

Given equation:

\sf 10 + (x)/(3) = 13

\n

Subtract 10 from both sides:

\sf 10 + (x)/(3) - 10 = 13 - 10 \n \n \sf (x)/(3) = 3

\n

Multiply both sides by 3:

\sf 3 * (x)/(3) = 3 * 3 \n \n \n \boxed{\boxed{\sf x = 9}}
