f(x) is a function that takes some number x and outputs another one.
To get the output value, replace every instance of x in f(x) with the given number.
1. If f(x) = x ² - 4x, then
f (-3) = (-3)² - 4(-3) = 9 + 12 = 21
2. f(x) = x ² - x, so
f (-10) = (-10)² - (-10) = 100 + 10 = 110
3. f(x) = 3x + 1, so
f (-3) = 3(-3) + 1 = -9 + 1 = -8
4. f(x) = 4x - 2, so
f (8) = 4(8) - 2 = 32 - 2 = 30
5. f(x) = x ² + 2, so
f (0) = 0² + 2 = 0 + 2 = 2

the side length of the following right isosceles triangle is 10 cm. if the area of a equals the area of b, then what is the area of the circle which the sector aef is in?
For problems a - d, write the function in the form LaTeX: y=ab^x. y = a b x . a) LaTeX: y=3\sqrt{4^{2x}} y = 3 4 2 x b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 c) LaTeX: y=8^{x+2} y = 8 x + 2 d) LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}
Step-by-step explanation:
To write the equation in LaTeX in form y = ab^x or [tex]ab^x[/tex] for y = abx .........(1)
(a) LaTeX: y=3\sqrt{4^{2x}} y = 3 4 2 x can be written in mathematical form as
[tex]y=3\sqrt{4^{2x}}[/tex] ; y = 342x
on comparing with equation (1) we get a =3 and b =4
⇒y = 34^x or [tex]34^x[/tex]
(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as
[tex]y=\frac{\sqrt[3]{5^{3x}}}{2}[/tex] ; y = 342x
on comparing with equation (1) we get a =0.5 and b =5
⇒y = [tex]\frac{1}{2}5^x[/tex]
(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as
[tex]y=8^{x+2}[/tex]
on comparing with equation (1) we get a =64 and b =8
y = [tex]64 . 8^x[/tex]
(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}} can be written in mathematical form as
[tex]y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}[/tex] = [tex]3^{x+1}[/tex] = [tex]3 . 3^x[/tex]
on comparing with equation (1) we get a =3 and b =3
y = [tex]3 . 3^x[/tex]

Answer:
Thw answer is 32
Step-by-step explanation:
Answer:
She should sell 32 plans.
Step-by-step explanation:
If she earns 7.5% of $1,500 on each plan she sells, that mean she makes $112.50 on each plan sold. Divide $3,600 by that and you get how many plans she should sell to make $3,600 this month. (3600 / 112.5 = 32)

the sum of a number times 4 and 29 is at least 26
Answer:
4 + 29 ≥ 26.
Step-by-step explanation:
I'm assuming you want me to make an inequality with this, so I will do that. Since sum means to add, we write this: 4 + 29. At least can translate to greater than or equal to, we can write that symbol as ≥. Now, let's write the whole inequality, we can write it as 4 + 29 ≥ 26.

Example: At a baseball game, Henry bought 3 hotdogs and a bag of chips for $14. Scott bought 2 hotdogs and a
bag of chips for $10. Each of the boys paid the same price for their hotdogs, and the same price for their chips. The
following system of equations can be used to represent the situation. Determine the best method to solve the system
of equations. Then solve the system.
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips

At least has to be the number or more.
So it could be 8, 9, 10... basically any number that's 8 or more.
Answer:
B) x ≥ 8
Step-by-step explanation:
x represents the number of dollars that Anna has.
If Anna has at least 8 dollars, she could have 8 or any number greater than 8 dollars. Anna could have 8, 9, 10, 11... etc. dollars.
This means that x is equal to or greater than 8.

Oscar made 28 out of 35 field goals during football practice. Which proportion shows how to find the percent of field goals made?
Answer:
80 %
Step-by-step explanation:
Step one:
Given data
We are told that Oscar made 28 out of 35 field goals during football practice.
Required
The percentage accuracy
Step two:
% Accurracy= number of goals/number of practice*100
% Accurracy= 28/35*100
% Accurracy=0.8*100
% Accurracy= 80%
Hence the percentage that he made is 80 %

A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks. Which spinner simulation uses an appropriate device and has the correct number of trials? a spinner divided into 5 congruent sectors, spun 3 times a spinner divided into 5 congruent sectors, spun 4 times a spinner divided into 2 congruent sectors, spun 3 times a spinner divided into 2 congruent sectors, spun 4 times
B. A spinner divided into 5 congruent sectors, spun 4 times
Have a good day
The correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks.
The correct spinner to use among the 4 should have a probability of winning of 80%, similar to what the owner has found out. So, we must calculate the probability of each spinner.
1. Spun 3 times, and chance of winning is 1 in 5, therefore P = (3) (1/5) = 0.6 = 60%
2. Spun 4 times, and chance of winning is 1 in 5, therefore P = (4) (1/5) = 0.8 = 80%
3. Spun 3 times, and chance of winning is 1 in 2, therefore P = (3) (1/2) = 1.5 = 150%
4. Spun 4 times, and chance of winning is 1 in 2, therefore P = (4) (1/2) = 2 = 200%
We can see that there is only 1 choice that has 80% probability,
Hence, the correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”
