help me write an expression to find perimeter.

Answer:

a) -4

b)

x    h                   [f(x+h) - f(x)] / h

3    2                  -4

3    1                   -4

3    0.1                -4

3    0.01              -4

Step-by-step explanation:

a) The difference quotient is:

[f(x+h) - f(x)] / h

Our function is -4x + 7​, then:

f(x+h) = -4(x+h) + 7​ = -4x -4h + 7

f(x) = -4x + 7​

f(x+h) - f(x) = -4x -4h + 7 - (-4x + 7​ )= -4x -4h + 7 +4x - 7​ = -4h

Finally:

[f(x+h) - f(x)] / h =  -4h/h = -4

b)

First point in the table:

x = 3

h = 2

f(x+h) = -4(3+2) + 7​ = -13

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -13 -(-5) = -8

[f(x+h) - f(x)] / h = -8 / 2 = -4

Second point in the table:

x = 3

h = 1

f(x+h) = -4(3+1) + 7​ = -9

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -9 -(-5) = -4

[f(x+h) - f(x)] / h = -4 / 1 = -4

Third point in the table:

x = 3

h = 0.1

f(x+h) = -4(3+0.1) + 7​ = -5.4

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -5.4 -(-5) = -0.4

[f(x+h) - f(x)] / h = -0.4 / 0.1 = -4

Fourth point in the table:

x = 3

h = 0.01

f(x+h) = -4(3+0.01) + 7​ = -5.04

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -5.04 -(-5) = -0.04

[f(x+h) - f(x)] / h = -0.04 / 0.01 = -4

Look at the picture*

The inequality equations are given as |x - 4| ≤ 1 and |y - 6| ≤ 2, then the correct option is B.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

From the diagram, the inequalities equation will be given as

For x, we have

[tex]\begin{aligned} 3 &\geq \ \ \ \ x&\geq 5\\-1 &\geq x-4&\geq 1\end{aligned}[/tex]

Then after the mode function, we have

[tex]|x-4|\leq 1[/tex]

Similarly, for y, we have

[tex]\begin{aligned} 4 &\geq \ \ \ \ y&\geq 8\\-2&\geq y-6&\geq 2\end{aligned}[/tex]

Then after the mode function, we have

[tex]|y-6|\leq 2[/tex]

Answer:

An expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01

Step-by-step explanation:

Let a represents the number of pounds of apples

Let b represents the number of bananas

Cost of 1 pound apple = $1.79

So, Cost of a pounds apples = 1.79 a

Cost of 1 banana = $0.36

Cost of b bananas = 0.36b

Cost of 3 lb bag of potato i.e. 3 pounds of potato = $2.99

So, Total cost = 1.79a+0.36b+2.99

Abigail has $30.00 to buy groceries

Let y be the change received by her

So, Change received by her:

y = 30-( 1.79a+0.36b+2.99)

y= 30-1.79a-0.36b-2.99

y=-1.79a-0.36b+27.01

Hence  expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01

Answer:

  3/10 liter

Step-by-step explanation:

Assuming your description means that 4/3 liters of punch includes 2/5 liters of water, then the fraction of punch that is water is ...

  (2/5)/(4/3) = (2/5)(3/4) = 3/10

3/10 of a liter of water is used in each liter of punch.
