f(-2)=3(-2) +4

f(-2)=-6+4

f(-2)=-2

Kryger [21]3 years ago

For this case we have a function of the form:

y = f (x)

Where f (x) = 3x + 4

If we have the value ofx = -2, substituting we have:

f (-2) = 3 (-2) +4

We solve the multiplication taking into account that + * - = - and 3 * 2 = 6

f (-2) = - 6 + 4

It is known that different signs are subtracted and the sign of the major is placed.

f (-2) = - 2

Thus,f (x) = 3x + 4 evaluated at x = -2is:f (-2) = - 2

Answer:

f (-2) = - 2

Answer:

The correct option is B.

Step-by-step explanation:

The amount of money, in dollars, in a savings account after x years is given by  M(x) = 10000(1.03)^{x}

This above equation represents that $10000 becomes M(x) after x years at a rate of interest 3% compounded in each year.

Therefore, the value in the expression 1.03 represents that there is a 3 percent increase in the savings account each year.

So, the correct option is B. (Answer)

Answer is 4/7

You divide the length of C'D' over the length of CD
C'D'/CD = 8/14 = 4/7

The scale factor is smaller than 1, so C'D' is shorter than CD

A class has $90 to spend on a field trip. The field trip costs $2.50 per person and there will be 5 chaperones on the trip. One
vodka [1.7K]

Answer:

Step-by-step explanation:

x is the number of students

(x+5) is the number of students and chaperons

$2.50·(x+5) is the amount of money the number of students and chaperons will pay for the trip, and that number should be less or equal than $90 because those are all the money they have

2.50(x+5) ≤ 90 which is the same as 90 ≥ 2.50(x+5)

The inequality "90 greater-than 2.50 (x + 5) "

90 > 2.50(x+5) is an error becase it excludes the possibility that <u>the trip can cost exact $90</u> so we need not just greater than > , yet greater and equal than ≥ sign

90 ≥ 2.50(x+5)
