Find f(2) if f(x) = (x + 1)2.
a 9
b 6
c 5
Answer:
b
Step-by-step explanation:
x = 2 in this situation, so plug in 2 for x.
f(2) = (x + 1)2
f(2) = (2 + 1)2
f(2) = (3)2
f(2) = 6
f(2) = 6. That means b is the answer.

3 + 5 = 8 which is a monomial
Step-by-step explanation:
a binomial has 2 terms; example, 3y + 5
solve for x using the correct order operations
12- (3 times 2)^2 + 4 times 3 = x
A x = -60
B x = -12
C x= 48
D x = 12
please help i will give brainliest :))
Answer:
B: x = -12
Step-by-step explanation:
12 - (3 × 2)^2 + 4 × 3
Use PEMDAS, meaning solve what's in the parentheses first (P stands for parentheses)
12 - (6)^2 + 4 × 3
We get 6 because 3 × 2 = 6
Next step is solve any exponents (E for exponents)
12 - 36 + 4 × 3
We get 36 because 6 × 6 = 36 (the exponent was 2 meaning multiply the same number, 6, twice: 6 × 6)
Now we move on to multiplication and division (M for multiplication and D for division)
These are interchangable in that either can go first depending on its location in the equation
However, since there is no division in this problem we automatically skip to multiplication
12 - 36 + 12
We answered 12 because 4 × 3 = 12
Our last steps in PEMDAS are addition and subtraction (A for addition and S for subtraction)
These are also interchangable, but both are apparent in this problem
Now it depends on location
Whichever sign (addition or subtraction) is first in accordance from left to right is where we start first)
Subtraction is first
-24 + 12
Now we add -24 + 12
-12
Lupita bought 7 pounds of pretzels at a local wholesaler for $16.80. Her friend Charles bought 5 pounds of pretzels at the supermarket for $12.75. Charles thinks he got the better deal because $12.75 is less than $16.80. Is Charles’s reasoning correct? Explain why or why not.
Answer:
Charles's reasoning is wrong.
Step-by-step explanation:
Lupita has 7 pounds for 16.8 and Charles has 5 pounds for 16.8.
Let's set up ratios.
So Lupita got the best deal, not Charles. Poor him.

Answer:
[tex]\frac{1}{64}[/tex]
Step-by-step explanation:
(1/8)^2 is actually just (1/8)*(1/8)
We multiple the numerators, 1*1, to get 1,
And the denominators, 8*8, to get 64
So the anwser is (1/64)
A cup is filled with pencils. The teacher sharpen 1/4 of them. A student sharpen 2/3 of them. The fraction of pencils left to be sharpened is?

solve the following system by substitution y=5x-4 y=6x
Answer:
Step-by-step explanation:
y = 5x - 4
y = 6x $\Rightarrow$ x = y/6
y = 5*y/6 - 4
y = 5y/6 - 4
6y = 5y - 24
y = -24.
So, x = -4

Sara and Fiona have played 53 tennis matches.
Sara has won 29 times.
Fiona won the rest.
a) Estimate the probability that Sara wins.
b) Estimate the probability that Fiona wins.
Answer: Sara = 29/53
Fiona = 24/53
Step-by-step explanation: because that amount is how much they have won and how much its out of so for example ‘i played 26 games i only won 17 and John won the rest’ the probability that i win is
17/26 and Johns would be 9/26

Is 3 a factor of 245 - 16?
yes
no
HELPPP
Answer:
No
Step-by-step explanation:
For 3 to be factor your finale number has to be divisible by 3, so with that information all you have to do is subtract 245-16 which is 229, and if you divide 229 by 3 it does not equal a whole number so 3 cannot be a factor.
I hope this helps, and have a great day! :D

7x + 2y = 12
-3x -2y = 4
Answer:
(4, -8) or x=4 y=-8
Step-by-step explanation:
Answer: x=4 and y=−8
Step-by-step explanation: 7x+2y=12, −3x−2y=4
7x+2y+−2y=12+−2y
7x /7 = −2y+12 /7
x= −2 /7 y+ 12 /7
−3( −2 /7 y+ 12 /7 )−2y=4
−8 /7 y+ −36 /7 + 36 /7 =4+ 36 /7
−8 /7 y / /−8/7 = 64 /7 /−8 /7
y=−8
x= −2 /7 y+ 12 /7
x= −2 /7 (−8)+ 12 /7
x=4
x=4 and y=−8
