Answer:

d ≤3

Step-by-step explanation:

9−4d≥−3

Subtract 9 from each side

9-9−4d≥−3-9

−4d≥−12

Divide by -4, remembering to flip the inequality

-4d/-4 ≤-12/-4

d ≤3

Answer:

C.

Multiply the first equation by 18; multiply the second equation by 18; add the equations.

D.

Multiply the first equation by − 6; multiply the second equation by 4; add the two equations.

E.

Multiply the first equation by 3; multiply the second equation by − 2;add the two equations.

Step-by-step explanation:

All of these procedures work because they are canceling out the x and y values in both equations.

Step-by-step explanation:

Andre and his dad have been fishing for 2 hours. In that time, they have caught 9 blue gills and 1 yellow perch. How many total fish are there?

There are 10 total fish. We are looking at how many fish there are, so we need  to add 9 + 1 to get our answer of 10 fish.

The next time Andre gets a bite, what kind of fish do you think it would be?

My prediction is that it will be a blue gill.

How do you know your prediction is more likely to happen?

9 out of 10 times, they have caught a blue gill. This is more probable than 1 out of 10.

Can you make any other predictions?

I would say that Andre will catch less yellow perches than blue gills. This is because the probability of catching a blue gill is greater than catching a yellow perch. I would also say that Andre will catch 5 fish per hour, since he caught 10 fish in 2 hours.

Answer:

∠ f = 33°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin f = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{36}{66}[/tex] , thus

∠ f = [tex]sin^{-1}[/tex] ([tex]\frac{36}{66}[/tex] ) = 33° ( to the nearest degree )

Answer:

A salary with commission involves an employee have a fixed slary base but also receive commission for sales or performance.

Equation:   y = 1,478.00 + (249.00)(x)

Step-by-step explanation:

Step 1:

You will multiply the $249 commission rate and the number of each policy he sells. (249)(x)

Step 2:

You then add the monthly salary of 1,478.00 and the answer from step one.

1,4789 + (answer from step 1)

Step 3:

The sum of step 2 is Carson's total pay for the month.

Answer:

x = 3

Step-by-step explanation:

Data

Therefore:

From  Intersecting Secants Theorem :

CD*CE = CB*CA

Replacing with data:

(x + 1)*(x + 15) = x*(x + 21)

x² + 15x + x + 15 = x² + 21x

x² + 15x + x + 15 -x² - 21x = 0

15 - 5x = 0

15 = 5x

15/5 = x

3 = x

Answer:

Not a Proportional Relationship ; No Constant of Proportionality

Step-by-step explanation:

Consider the first example, 4 hours of parking costs $ 10. From this we can derive the ratio 4 : 10, so that hours parked : fee for parking is a common ratio among the two examples, the other being 5 : 12;

[tex]4 : 10, Simplify\\2 : 5, Take As Fraction,\\Solution; 2 / 5ths\\[/tex]

[tex]5 : 12, Simplify\\( Can't Be Simplified Further ) - Take as Fraction,\\Solution; 5 / 12ths[/tex]

Considering that the fractions when compared are not similar, ( 2 / 5, and 5 / 12 ) they don't have a proportional relationship, and thus have no constant of proportionality

Solution; Not a Proportional Relationship

Answer:

y=3x+1

Step-by-step explanation:

First, we have to find the slope. [tex]\frac{4-(-5)}{2-(-1)}[/tex] This comes out to 9/3. This becomes 3. Now we need to find the y-intercept. Now write out how to find the answer. 4=3(2)+b. 4=3+b. Subtract 3 from both sides to get 1=b. Now write out the equation. y=3x+1

Answer: a. 55

Step-by-step explanation:

The formula to find the geometeric mean between two numbers a and b is given by :-

[tex]G.M. =\sqrt{ab}[/tex]

The given numbers are : 275 and 11

The geometric mean of 275 and 11 is given by :-

[tex]G.M.=\sqrt{275\times11}\\\\\Rightarrow\ G.M. =\sqrt{3025}\\\\\Rightarrow\ G.M.=\sqrt{55\times55}\\\\\Rightarrow\ G.M.=\sqrt{55^2}\\\\\Rightarrow\ G.M.=55[/tex]

Hence, the geometric mean of 275 and 11 is 55.

So , the correct option is a. 55 .

Answer:

x = 13.5

Step-by-step explanation:

Once again, these two traingles share angle A and both have right angles. This shows AA similarity.

Now knowing this, we can set up a ratio:

(x+3)/3 = 11/2

Mulptiply both sides by 6:

2x+6 = 33

Isolate x:

2x = 27

divide by 2:

x = 13.5

Answer:

x=13.5

Step-by-step explanation:

i similar triangles sides are proportional.

[tex]\frac{x+3}{3} =\frac{11}{2} \\2x+6=33\\2x=33-6\\2x=27\\x=27/2=13.5[/tex]

Answer:

B) y=3x+7.5

Step-by-step explanation:

The equation of the data in the table can be obtained by using any two points.

We will use points (3, 13) and (5,17)

The slope - intercept form is:

We find the slope as:

The equation becomes:

To find the value of b, the y -intercept is:

So the equation is:

A) y = 2x + 8.5

B) y=3x+7.5

C) y=5x+6.5

D) y=10x+5.5

Answer:

Step-by-step explanation:

4x + y = 27

5x -y = 18

9x = 45

x = 5

4(5) + y = 27

20 + y = 27

y = 7

Answer:

The values of x that makes f(x) have a valid asymptote are 1 and 8

Step-by-step explanation:

Given

[tex]f(x) = \frac{9}{(x-1)(x-8)}[/tex]

Required

At what value does f(x) has a vertical asymptote

To solve this, we simply equate the denominator of f(x) to 0;

This is done as follows

[tex]{(x-1)(x-8)} = 0[/tex]

This can be split to

[tex]{(x-1) = 0 \ or\ (x-8)} = 0[/tex]

Remove brackets

[tex]x-1 = 0 \ or\ x-8 = 0[/tex]

Make x the subject of formula in both cases

[tex]x-1+1 = 0+1 \ or\ x-8+8 = 0+8[/tex]

[tex]x= 0+1 \ or\ x = 0+8[/tex]

[tex]x= 1 \ or\ x = 8[/tex]

The values of x that makes f(x) have a valid asymptote are 1 and 8

Answer:

The correct answer is 1 and 8
