Answer:

x < 11

Step-by-step explanation:

–8x + 16 > –72

Let's transfer the components which do not contain x to the right side and change sign of these components

-8x > -72 - 16

Now, we simplify the right side

-8x > -88

We then multiply both sides by (-1/8) and change the greater symbol to smaller symbol

(-1/8)*(-8)x < (-1/8)*(-88)

Finally, we simplify both sides to solve this inequality

x < 11

Answer with Step-by-step explanation:

We are given that a function

[tex]f(x)=x^3-x^2-17x-15[/tex]

We have to find the graph of the given function.

y-intercept:It is that  value of y where the graph cut the y- axis.

Let

[tex]y=f(x)=x^3-x^2-17x-15[/tex]

Substitute x=0

Then, we get

[tex]f(0)=-15[/tex]

y-intercept of the graph=-15

x- intercept: It is that value of x where the graph cut the x- axis.

Substitute y=0

[tex]x^3-x^2-17x-15=0[/tex]

Substitute x=-1

[tex]-1-1+17-15=0[/tex]

Therefore,x=-1  is a solution of given equation.

[tex](x+1)(x^2-2x-15)=0[/tex]

[tex](x+1)(x^2-5x+3x-15)=0[/tex]

[tex](x+1)(x(x-5)+3(x-5))=0[/tex]

[tex](x+1)(x+3)(x-5)=0[/tex]

[tex]\implies x=-1,-3,5[/tex]

Hence, the x-intercept are

-3,-1 and 5

Answer:

His profit from mowing x lawns is 19x-15

Step-by-step explanation:

Revenue for mowing x lawns = 25x

Cost for gas and the mower rental = 6x+15

We are supposed to find His profit from mowing x lawns

p(x) denotes His profit from mowing x lawns

Profit = Revenue - Cost

So,p(x)=25x-(6x+15)

p(x)=25x-6x-15

p(x)=19x-15

So, Option B is true

Hence His profit from mowing x lawns is 19x-15

[tex]\boxed{\sf \ \ \ 15 \ \ novelists \ \ and \ \ 9 \ \ poets \ \ \ }[/tex]

Step-by-step explanation:

hello,

let's note a the number of novelists and

b the number of poets.

we know that a = 5/3 b as "enrolls novelits and poets in a ratio of 5:3"

it comes 3a=5b which is the first equation

and we know that a + b = 24 "there are 24 people"

we we have two equations

(1) 3a - 5b = 0

(2) a + b = 24

let's multiply (2) by 3 it comes 3a + 3b = 24*3 = 72

let's do 3*(2) - (1) it comes

3a + 3b -3a + 5b = 72 - 0 = 72

so 8b = 72

so b = 9

and then we replace b in (2) it comes

a = 24-9 = 15

Answer:

The equations are:

[tex]\text{shortest} = \text{length} - \frac{\text{tolerance}}{100}*\text{length}\\\text{shortest} = 2 - \frac{4}{100}*2 = 1.92\\\text{longest} = \text{length} + \frac{\text{tolerance}}{100}*\text{length}\\\text{longest} = 2 + \frac{4}{100}*2 = 2.08\\[/tex]

Step-by-step explanation:

The ideal length of the bolt is 2.0 cm, since it has a tolerance of 4%, this means that length values between [tex]2 + \frac{4}{100}*2[/tex] and [tex]2 - \frac{4}{100}*2[/tex] are acceptable, because by those expressions the length of the bolt will be 4% higher or lower than it's original length. With this in mind let's find it's values:

[tex]\text{shortest} = \text{length} - \frac{\text{tolerance}}{100}*\text{length}\\\text{shortest} = 2 - \frac{4}{100}*2 = 1.92\\\text{longest} = \text{length} + \frac{\text{tolerance}}{100}*\text{length}\\\text{longest} = 2 + \frac{4}{100}*2 = 2.08\\[/tex]

Scale = 1/200 = 1 : 200

Therefore, 1 centimeter on the plan represent 200 centimeters on the original length.

Step-by-step explanation:

Scale is the ratio of the original object to the drawn plan.

Scale = plan : original

Scale = plan length ÷ original length

Plan length = 7.5 centimeters

Original length = 1.5 meters = 1,500 centimeters

Substituting the values;

Scale = 7.5/1500 = 1/200

Scale = 1 : 200

Therefore, 1 centimeter on the plan represent 200 centimeters on the original length.
