What equation can be used to create the sequence -3, 2, 7, 12,

Answers

Answer:

y=x+5

Step-by-step explanation:

You can tell by looking at the sequence that each number is five more than the previous. With that in mind, you know that, to find the next number in the sequence, you have to add five to the one before it.

Making x the previous number and y the next number in the sequence, you get the equation y=x+5

You can plug pairs from the sequence to check:

2= -3+5

2=2

------------

7= 2+5

7=7

12= 7+5

D. 51b−24
E. 11b+187−2,756÷13

Answers

Answer:

A, and D

Step-by-step explanation:

If you go through all the problems, just replace "b" with "(4)" into a calculator. For A and D, they both equaled 180.

The expression that has a value of 180 when b = 4 is D. 51b−24

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

87b - 179 + 957/87.

= 87(4) - 179 + 857/87.

= 348 - 179 + 9.85, will not be 180.

33b12, will not be 180 at b = 4.

b² + 120,  will not be 180 at b = 4.

51b - 24.

= 51(4) - 24.

= 204 - 24.

= 180.

11b + 187 - 1756/13.

= 11(4) + 197 - 135.07, will not be 180 at b = 4.

Subtraction Property of Equality and Division Property of Equality

Understanding Properties of Equality

What Kira wants to solve is;

72 - 2x = 11

The first step is to use the Subtraction property of equality to combine the constant terms. Thus;

72 - 2x - 72 = 11 - 72

-2x = -61

The second step is to use the Division property of equality to isolate the variable to get;

-2x/-2 = -61/-2

x = 61/2

Using the graph below, what is the value of f(8)?

Answers

Answer:

0

Step-by-step explanation:

When a problem asks for the value of f(x), find the y value for the given x value. In this instance, since x = 8, y = 0.  

From the graph the value of f(8) is 0.

what is Function?

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

From the graph we have to find f(8)

This shows that the values of function at x=8

Now, focusing on the x- axis we have keep point on x= 8 then move and where the line touches the functional line we get the result.

Hence, from the graph the value of f(8) is 0.

-2h = a[tex]t^{2}[/tex] - 2; add 2 to both sides

Answers

Answer:

  a) 10(3x+2) ≤ 140; x ≤ 4

  b) no

Step-by-step explanation:

a) The area is the product of length and width. We want that product to be no greater than 140:

  10(3x +2) ≤ 140 . . . . your inequality

We can solve this by dividing by 10 first.

  3x +2 ≤ 14

  3x ≤ 12 . . . . . . subtract 2

  x ≤ 4 . . . . . . . . divide by 3; the solution to the inequality

__

b) If the length were 15, the area would be 10×15 = 150, which is greater than 140. The length cannot be 15 if the area is at most 140.
