Consider the linear function f(x) = 3x-1. Find f(0), f(1), f(2)

Answers

Answer:

f(0) = -1, f(1) = 2, f(2) = 5.

Step-by-step explanation:

f(0) = 3(0) - 1 = -1

f(1) = 3(1) - 1 = 2

f(2) = 3(2) - 1 = 5

The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function is given below.

f(x) = 3x + 1

The value of the function at x = 0 will be

f(0) = 3(0) + 1

f(0) = 0 + 1

f(0) = 1

The value of the function at x = 1 will be

f(1) = 3(1) + 1

f(1) = 3 + 1

f(1) = 4

The value of the function at x = 2 will be

f(2) = 3(2) + 1

f(2) = 6 + 1

f(2) = 7

The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.

which inequality is true when the value of w is 13 w-<5 -w-3>-5 -w-3>5 w->5

Answers

w > -5 shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true

We need to get the equation that is true for w to be 13. This means that the required inequality expression should be w must be a positive integer.

For the Expression -w - 3 > -5

-w > -5 + 3

-w > -2

w < 2

Since w is less than 2, hence the inequality is wrong

For the inequality

-w - 3 > 5

-w > 5 + 8

-w > 13

w < -13

Since w < -13, hence the inequality is wrong

For the inequality w > -5

It shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true

Answer:  See explanation:  10, 1, 1, -7

Step-by-step explanation:

I'll assume you are working with Excel.  The Product function multiplies all the cells given in the specified range.  Here, those are cells A2 through A5.  As presnted, this would be [10*5*0*(-7)] = 0, which is the value of cell B2.  If we want cell B2 to be -70, we must change one or more of the numbers in cells A2 to A5.

Initial:     10, 5, 0, -7   B2=0

Change:  10, 1,  1, -7   B2 = -70

The state fair is a popular field trip destination. This year the senior class at High School A and
the senior class at High School B both planned trips there. The senior class at High School A
rented and filled 1 van and 3 buses with 80 students. High School B rented and filled 14 vans
and 1 bus with 218 students. Each van and each bus carried the same number of students. Find
the number of students in each van and in each bus.

Answers

Answer:

each bus carries 22 students

each van carries 14 students

Step-by-step explanation:

1v+3b=80

14v+b=218

eliminate b by multiplying the bottom equation by 3.

(42v+3b=654)-(1v+3b=80)=

41v=574

divide both sides by 41

v=14 (each van carries 14 students)

substitute the value of v into either of the og equations

1(14)-14+3b=80-14

3b=66

divide both sides by 3

b=22 (each  bus carries 22 students)

solve this equation using completing the square method 2x^2 -x -8 =0​

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double-time rate. Her gross pay was $734.40.

The hourly rate will be calculated as:-

Rate = 40 + 2 x 4 = 734.40

Rate = 40 + 8 = 734.40

Rate = 734.40 / 48

Rate = $15.3

The hourly rate is $15.3.
