Answers

Answer 1

Answer:

Your answer is option a.

Answer 2

Answer:

a. 9(8+7)

Step-by-step explanation:

If you distribute the 9 into the equation, You're basically multiplying the 9 by each term so it really becomes:

(9*8) + (9*7)

Which leaves you with:

72 + 63

Answer:

y = x + 2

Step-by-step explanation:

The slope of the given points (6, 8) and (2, 4) is m = 1.

The y-intercept found through the slope, m = 1, is b = 2.

So, m = 1 and b = 2, right?

Let's put this together into the formula y = mx + b, we'll get: y = x + 2

In Argument A the conclusion indicator  is "we may infer that" and the conclusion  is Kari is more likely to be pulled over.

In Argument B the conclusion indicator  is "For these reasons" and the conclusion  is You should never run with scissors.

In Argument C the conclusion indicator  is "So" and the conclusion  is Humans do not have free will.

To identify the conclusion of each argument, we can either separate the premises (examples of the author's opinion) from the entire argument or we can identify the conclusion indicators.

Some conclusion indicators include:

therefore, thus, hence, so, for these reasons, we may infer, as a result,consequently, etc

Argument A:

conclusion indicator = we may infer that

Conclusion = Kari is more likely to be pulled over.

Argument B:

conclusion indicator = For these reasons,

Conclusion = You should never run with scissors

Argument C:

conclusion indicator = So,

Conclusion = Humans do not have free will

The average price of a 0.5- carat round diamond is $3700 and the average price of a 0.75- carat diamond is $4950. If the weight and the price of the diamond is linearly related, how much will a 2.5 -carat round diamond cost?

Answers

Since the problem stated the weight and price are in a linear relationship, we can use y=mx+b.

First, let's calculate our slope.

m = (4950-3700)/(0.75-0.5) = 5000

Now, let's solve for b.

3700 = 5000(0.5) + b

Simplify the right side of the equation.

3700 = 2500 + b

Subtract 2500 from both sides

1200 = b

Now our equation looks like this:

y  = 5000x + 1200

Let's plug 2.5 in for x to solve for the diamond cost.

y = 5000(2.5) + 1200

Simplify the right side.

y = 13700

The average price of a 2.5 carat diamond is $13700

Find the midline for f(x)=sinx+1.

B. y=−1
C. y=1
D. y=−2

Answers

Answer:

B Y=1

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

What is the greatest value that sin(x) + 1 can have? It isn't 1.

f(90) = sin(90) + 1

f(90) = 1 + 1 = 2

What is the smallest value that sin(x) + 1 can have? It still isn't one.

f(-90) = sin(-90) + 1

f(-90) = -1 + 1 = 0

So the midline is (2 + 0)/2 = 1

y = 1 is the answer.

Water flows out of a hose at a constant rate. After 2 1/3 minutes, 9 4/5 gallons of water have come out of the hose. At what rate, in gallons per minute, is water flowing out of the hose?

Answers

Time taken:  2[tex]\frac{1}{3}[/tex] minutes = 7/3 minutes

Water released: 9[tex]\frac{4}{5}[/tex] gallons = 49/5 gallons

Rate of water flowing out:

How many gallons of a 70% antifreeze solution must be mixed with 90 gallons of 15% antifreeze to get a mixture that is 60% antifreeze? Use the six-step method.

Answers

Answer:

405 gallons

Step-by-step explanation:

Let it be that the amount of gallons of a 70% antifreeze solution  is x, when a mixture that is 60 percents of antifreeze is placed in y gallons

x+90=y - the equation of dependence between solutions

The amount of antifreeze in the first one is x/100*70= 0.7x (in gallons), in the second solution (15percents) antifreeze is 90/100*15=13.5 (in gallons).

In the mixture we should get there will be y/100*60=0.6y - gallons of antifreeze

0,7x+13.5=0.6y

We have two equations x+90=y and 0,7x+13.5= 0.6y

0.6x+54=0.6y

0.7x+13.5=0.6y

0.7x+13.5-0.6x-54= 0.6y-0.6y

0.1x-40.5=0

x=405- the answer

p.s. sorry, I don't know what the six-step method is. But the answer is right.

y=3 is a horizontal line so the slope is 0

9x-3y=18 can be written as 3y=9x-18 or y=3x-6 so the slope is 3

the line through (5,7) and (5,-8) is a vertical line since the x value didnt change between the two points so the slope is undefined

we have to find the slope of the line through ( – 4, – 1) and (-1,–7). to do this use the formula (y_2-y_1)/(x_2-x_1)=(-7-(-1))/(-1-(-4))=(-7+1)/(-1+4)=-6/3=-2 so the slope is -2
