Solve for X. - 7X - 50 less than or equal to -1 and -6X +70 greater than -2

Answers

Answer 1

Answer: x ≤ 7

Step-by-step explanastion: 7x-50≤ -1 and -6x +70> -2

Solve separately and then put back together

7x-50≤ -1

Add 50 to each side

7x-50+50≤ -1+50

7x ≤ 49

Divide each side by 7

7x/7 ≤ 49/7

x ≤ 7

-6x +70> -2

Subtract 70 from each side

-6x +70-70> -2-70

-6x> -72

Divide by -6, remembering to flip the inequality

-6x/-6 < -72/-6

x < 12

The first is more restrictive, and since it is an and, we use the more restrictive answer

Answers

it’s D I took the test

If Olivia has read 40 pages of a 70-page book. Then 57.196% of pages has Olivia read

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Olivia has read 40 pages of a 70-page book.

We need to find percent of pages has Olivia read

Let x be the percent of books olivia read.

This can be done by 70 x=40

Divide both sides by 70

x=40/70

x=0.5719

Now multiply this with 100

0.5719×100

57.196

Hence 57.196% percent of pages has Olivia read

The average monthly rent for one-bedroom apartments in Chattanooga has been $1200. Because of the downturn in the real estate market, it is believed that there has been a decrease in the average rental. The correct hypotheses to be tested are:_______

Answers

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is b

Step-by-step explanation:

From the question we are told that

The average monthly rent for one-bedroom apartment in Chattanooga has been

[tex]\mu = \$ 1200[/tex]

This mean that the null hypothesis is

[tex]H_o : \mu = \$ 1200[/tex]

Generally given from the question that it is believed that there has been a decrease in the average rental , it then mean that the alternative hypothesis is

[tex]H_a : \mu < \$ 1200[/tex]

use the defintion of the derivative to find the derivative of the given function. f(x)= 5 square root of x

Answers

Answer:

The derivative of function [tex]f(x)=5\sqrt{x}[/tex] is [tex]\frac{5}{2\sqrt{x} }[/tex]

Step-by-step explanation:

We need to find derivative of the given function [tex]f(x)=5\sqrt{x}[/tex]

Finding the derivative:

[tex]\frac{d}{dx}(5\sqrt{x} )[/tex]

Using the rule (a.f)' = a(f)', taking out constant value 5

[tex]=5\frac{d}{dx}(\sqrt{x} )[/tex]

We know [tex]\sqrt{x} =x^{\frac{1}{2}[/tex] Replacing [tex]\sqrt{x}[/tex]

[tex]=5\frac{d}{dx}(x^{\frac{1}{2}} )[/tex]

Applying derivative rule: [tex]\frac{d}{dx}(x^a)= a.x^{a-1}[/tex]

[tex]=5\times\frac{1}{2}(x^{\frac{1}{2}-1} )\\=\frac{5}{2}(x^{-\frac{1}{2}} )\\=\frac{5}{2x^{\frac{1}{2}}}\\=\frac{5}{2\sqrt{x} }[/tex]

So, the derivative of function [tex]f(x)=5\sqrt{x}[/tex] is [tex]\frac{5}{2\sqrt{x} }[/tex]

Jimmy borrowed $450 to start a lawn-mowing business. He charges $35 per lawn and it costs him $8 in operating costs per lawn.

What is the y-intercept of the line representing Jimmy's costs?

Answers

Answer: $450

Step-by-step explanation:

Given that:

Amount borrowed = $450

Amount charged per lawn = $35

Operating cost per lawn = $8

Jimmy's cost (C(x)) :

Amount borrowed + operating cost

If x lawns are mowed :

$450 + $8 per lawn

$450 + $8x

C(x) = 450 + 8x

Intercept (value of y when x = 0

Value of C(x) ; when x = 0

C(x) = 450 + 8(0)

C(x) = 450 + 0

C(x) = 450
