Answers

Answer 1
Answer:

Answer:

D

Step-by-step explanation:

Find (f + g)(x) then evaluate (f + g)(9)

(f + g)(x) = f(x) + g(x)

= 4x - 1 + x² - 2 = x² + 4x - 3

Now substitute x = 9 into the expression

(f + g)(9) = 9² + 4(9) - 3 = 81 + 36 - 3 = 114 → D

Answer 2
Answer:

Answer:

J.117

Step-by-step explanation:

f(x) =4x-1

if f(2)= 4(2)-1

f(2)= 8-1 = 7

f(2) = 7 equation 1

g(x) =x2-2

if g(4)= (4)2-2

g(4) = 8-2 = 6 equation 2

Now,

(f+g)(9) =?

subtitute equation 1 and 2

(7+6)(9)=?

(13)(9)=?

13×9= 117

Hence, the answer is 117

sergei caught 4 striped fish. each one weighed the same number of pounds. then he caught another fish that weighed 8 pounds. which expression represents the total weight of the fish that sergei caught

Answers

Answer:

the answer is 4p+8

Step-by-step explanation:

caught and another are the key words here. These words mean addition so therefore it is 4p+8.

8 x 5 = 32 is the expression. Since Sergei caught 4 striped fish that all weigh the same, we know that we can multiple the weight of one fish by the amount of fish he caught.

Since he also caught another fish that would make the total of fish 5.

Write an expression for: the product of 3 and the quantity of a number minus 7

Answers

"The product" immediately suggests multiplication; we're going to be multiplying two quantities together, "3" and "a number minus 7"

"A number" just describes an unknown value, so we'll pick the letter n to be that unknown in our expression. "A number minus 7" then could be written as n - 7.

We can now write the product of 3 and (n - 7) as the expression

3 × (n - 7)

Final answer:

The expression that represents 'the product of 3 and the quantity of a number minus 7' can be written in algebra as 3*(x - 7). Here, x is our variable and can be any number.

Explanation:

The student is asking for an expression that represents 'the product of 3 and the quantity of a number minus 7'. In terms of algebra, this can be expressed in the following way: assuming the 'number' is represented by a variable, like x, we can write it as 3*(x - 7).

This mathematical expression says that we first subtract 7 from our number, x, and then multiply the result by 3.

For example: if x is 10, we would first calculate 10 - 7, which is 3, and then multiply that result by 3, yielding a final product of 9.
