Answer:
C. f(5) = 13 and f(-3) = -3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
f(x) = 2x + 3
x = 5
x = -3
Step 2: Evaluate
x = 5
Substitute: f(5) = 2(5) + 3Multiply: f(5) = 10 + 3Add: f(5) = 13x = -3
Substitute: f(-3) = 2(-3) + 3Multiply: f(-3) = -6 + 3Add: f(-3) = -3We evaluate Separately.
Let x = 5
f(5) = 2(5) + 3
f(5) = 10 + 3
f(5) = 13
Now let x = -3.
f(-3) = 2(-3) + 3
f(-3) = -6 + 3
f(-3) = -3

Help me find a 3rd degree binomial
Step-by-step explanation:
A binomial expression has two terms. For example, 4x + 5,
The degree of any polynomial refers to the term with the highest exponent on its variable. For example, In expression 4x + 5, the exponent of x is 1 so it is 1st degree polynomial and in the same way, for since the variable y has the highest exponent i.e., 2 therefore it is 2nd degree polynomial.
Now, third degree binomial with constant term 8 =
As it has two terms where first term is and second term is 8. Therefore, it is called binomial and since the highest exponent with variable x is 3, therefore it is third degree binomial with constant term of 8.

At cultutral arts day each session lasts 4/5 hours. The principal has set aside 3 hours for the sessions. Determine the number of sessions that can be sheduled for each student
Answer: 3.75
Step-by-step explanation:
The following can be gotten from the question:
Time taken for each session = 4/5 hours
Total time set aside by principal = 3 hours
The number of sessions that can be sheduled for each student will be:
= Total time set aside by principal / time taken for each session
= 3 hours / 4/5 hours
= 3 × 5/4
= 3.75

Two friends, Aria and Kaylee, took summer jobs. The equation y = 20.2 x y=20.2x represents Kaylee's earnings in dollars and cents, y y, for working x x hours. Aria earned $737.20 in 38 hours.
Answer:
y=19.4x------represents Aria's earnings in dollars and cents,
Step-by-step explanation:
The question is not complete, however, the idea from this response can provide the needed solution and understanding
Step one:
The linear function for the earnings is given as
y = 20.2x-----this represents Kaylee Earnings.
y represents the total earnings
x represents the earning rate, in this situation it $20.2 per hour, this is also the gradient of the function m
Step two:
we want to find th equation for Aria earning
y= $737.20
time taken x=38 hours
737.2=m(38)
divide both sides by 38
m=737.2/38
m=19.4
this means that Aria earn $19.4 per hour
the function for Aria is
y=19.4x
Use the Remainder Theorem to determine whether or not x + 3 is a divisor of p (x) = 2x^3 + 4x^2 - 2x + 12

This is answer. I'm sri lankan. But our a/l exam have this mathematics questions
The remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).
Given the polynomial; p(x) = 2x³ + 4x² - 2x + 12, since it is divided by x + 3, hence:
x + 3 = 0
x = -3
p(-3) = 2(-3)³ + 4(-3)² - 2(-3) + 12 = -6
Hence the remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.

ron wants to buy a video game with a selling price of $60, on sale for 50% off. The sales tax in 4.5% state is . How much will he have to pay in all? If has $34, can he afford to purchase the game?
Answer:
Yes, he can.
Step-by-step explanation:
To find the sale, you need to times the sale percentage by the original price so
60 x 0.50 = 30
Then you subtract the original price by the sale price so
60 - 30 = 30
So the with the sale, the price is $30.
Now the tax
Do the same
30 x 0.045 = 1.35
Now instead of subtracting you add so
30 + 1.35 = $31.35
Yes, he can afford it.
