I don’t know how to solve it please help

Answers

Answer 1

Answer:

when x=0 then f(x) = -2

when x=1 then f(x) = 3

when x=2 then f(x) = 8

Step-by-step explanation:

you just plug in the x value given to you into the equation (which is 5x-2) so for example:

if x = 0 then:

5x-2 is instead 5(0)-2 which means you multiply 5 and 0 and then substract 2 because you have to follow PEMDAS

PEMDAS is (Parenthesis, Exponents, Multiplication, Division, Addition, Substraction) which is the order of priority to be solved, so you first solve parenthesis, then exponents, then you multiply or divide, and then you add or substract

easy way to remember PEMDAS: Please Excuse My Dear Aunt Sally, OR Please End My Depression And Suffering (my favorite way to remember, don't take that seriously tho >_>)

so because you have to multiply before subtracting you multiply 5 and 0, you get 0, and then you take away 2 which is -2

remember to just plug in your values and then do PEMDAS

hope you learned something :P

Simplify the expression. 1.7 – 2.7 – 1.34 + 4.9 – 1.48
please explain I'm lost

Answers

Answer:

Step-by-step explanation:

1.7 - 2.7 - 1.34 + 4.9 - 1.48

First we can group the positive and negative numbers

1.7 + 4.9 - 2.7 - 1.34 - 1.48

add the positive numbers then add the negative numbers

1.7 + 4.9 becomes 6.6

-2.7 - 1.34 - 1.48 becomes - 5.52

Now add both the answers

6.6 + (- 5.52) = 1.08

Answers

Answer:

Step-by-step explanation:

L = 3*w + 1 Given

P = 2*(L + w) Formula for Perimeter. Substitute for L

P = 2*(3w + 1 + w) Combine

P = 2*(4w + 1)

P = 58 Given

58 = 8w + 2 Remove the brackets

58 - 2 = 8w Subtract 2

56 = 8*w Divide by 8

56/8 = w

7 = w

================

Find L

L = 3*w + 1

L = 3*7 + 1

L = 22

================

Check

2L + 2W = 58

2*22 + 2*7 =? 58

44 + 14 = ? 58

58 = 58

The answer checks.

The sum of five consecutive even integers is 220. Find the middle value of the five consecutive integers.

Answers

Answer:

Step-by-step explanation:

If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:

220:5 = 44

Of course you can find them to be sure:

Consecutive even integers increase by 2.

So if 2x is the smallest of them (x is an integer), then the numbers are:

2x, 2x+2, 2x+4, 2x+6, 2x+8

So their sum: 10x+20

10x + 20 = 220 ⇒ 10x = 200 ⇒ 2x = 40

So the numbers are: 40, 42, 44, 46, 48

for a new neighborhood, 100 acres of land will be split into 10 lots. how many acres of land will each lot have?

Answers

Your answer is 10 cause 100 divided by 10 is 10 :)

Each lot will have 10 acres of land.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find out how many acres of land each lot will have, you can divide the total amount of land (100 acres) by the number of lots (10).

So,

= 100 acres ÷ 10 lots

= 10 acres per lot

Therefore,

Each lot will have 10 acres of land.
