the two points for each equation are:

For y = 2x + 9:

Point 1: (0, 9)

Point 2: (3, 15)

For -6x = 4 + 2y:

Point 1: (0, -2)

Point 2: (2, -8)

To find two points for each of the given equations, we can arbitrarily choose values for x and then calculate the corresponding y values.

For the equation y = 2x + 9:

Let's choose x = 0:

y = 2(0) + 9

y = 9

So, one point is (0, 9).

Let's choose x = 3:

y = 2(3) + 9

y = 6 + 9

y = 15

Another point is (3, 15).

For the equation -6x = 4 + 2y:

Let's choose x = 0:

-6(0) = 4 + 2y

0 = 4 + 2y

-4 = 2y

y = -2

One point is (0, -2).

Let's choose x = 2:

-6(2) = 4 + 2y

-12 = 4 + 2y

-16 = 2y

y = -8

Another point is (2, -8).

Therefore, the two points for each equation are:

For y = 2x + 9:

Point 1: (0, 9)

Point 2: (3, 15)

For -6x = 4 + 2y:

Point 1: (0, -2)

Point 2: (2, -8)

Answer:

$44

Step-by-step explanation:

Hello!

It said that 7 cameras cost $308, right?

If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:

7x = 308.

If 7x = 308, it would be

308/7 =

44.

So, $44 is the answer.

Answer:

A. 22.5

Step-by-step explanation:

Apply Trigonometric function.

Reference angle = 64°

Opposite side to 64° = x

Hypotenuse = 25

Apply SOH:

Sin 64 = Opp/Hyp

Sin 64 = x/25

25 × Sin 64 = x

22.4698512 = x

x = 22.5 (nearest tenth)

Step-by-step explanation:

The total cost of the car purchase, including the base price, freight charge, air conditioner cost, and license-related fees, is $68,937.

To calculate the total cost of the car purchase, we need to consider the base price of the car, the charge for freight, and the additional costs for the air conditioner and license-related fees.

Given:

Base price of the car: $64,987

Freight charge: $2,300

Additional costs:

Air conditioner cost: Let's assume it's $500 (not explicitly mentioned in the given information)

License-related fees: Let's assume it's $150 (not explicitly mentioned in the given information)

To calculate the total cost, we add up all the costs involved:

Total cost = Base price + Freight charge + Air conditioner cost + License-related fees

Total cost = $64,987 + $2,300 + $500 + $150

Total cost = $68,937

Answer:

81 cubic foot

Step-by-step explanation:

It is given that the box is packed with cubes whose side is 1 foot. So the volume of one cube is 1 cubic foot.

Now from the figure, we can see that :

Number of cubes fitting the box across its length = 9 cubes

Number of cubes fitting the box across its width = 3 cubes

Number of cubes fitting the box across its height = 3 cubes

And each of these cubes measures 1 x 1 x 1 cubic foot

So the volume of the box can be found out by:

Volume = length x width x height

             = 9 x 3 x 3

             = 81 cubic foot

Therefore volume of the box is 81 cubic foot.

Answer:

7.92 cm^3

Step-by-step explanation:

To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.

Answer:

Step-by-step explanation:

Im guessing since you have to estimate it then u have to round them up. So if you move both of their points by 2 spaces (divide both by 100) They will be 221x510.

Round them up to 200x500.

That woule be 100 000. Then at the end just dont forget to divide by 10000.

Answer:

False. It is not possible for a triangle to have two right angles.

Step-by-step explanation:

Every triangle has 3 sides and, therefore, 3 angles (hence its name "tri" (three) "angle" (angles). Always, the sum of the three angles of a triangle will have a value of 180º. Therefore If two of the angles of a triangle were right, that is, they measured 90º, the third angle would be 0º, that is, it would be non-existent.Therefore, it is impossible for two angles of a triangle to be right angles.

Answer:

The 99% confidence level (-0.741, -0.659).

Step-by-step explanation:

The average body mass index (BMI) in a sample of 1559 men was 30.4, with a standard deviation of 0.6.

The average BMI in a sample of 1924 women was 31.1 with a standard deviation of 0.2.

Find a 99% confidence interval for the difference between the mean weights..

The formula for 99% Confidence Interval for difference between the mean weights =

μ is the population mean, and σ is the population standard deviation.

μ1 - μ2 ± z × √σ²1/n1 + σ²2/n2

The z score for 99% confidence interval = 2.576

30.4 - 31.1 ± 2.576 × √0.6²/1559 + 0.2²/1924

-0.7 ± 2.576 × √0.36/1559 + 0.04/1924

-0.7 ± 2.576 × √0.0002309173 + 0.00002079

-0.7 ± 2.576 ×√0.0002517073

-0.7 ± 2.576 × 0.015865286

-0.7 ± 0.04086897674

Hence, the 99% Confidence Interval is

-0.7 - 0.04086897674

= -0.74086897674

≈ -0.741

-0.7 + 0.04086897674

=-0.65913102326

≈ -0.659

Therefore, the 99% confidence level (-0.741, -0.659).

Step-by-step explanation:

There is one 8 on a 12-sided die, so the probability of rolling an 8 once is [tex]\frac{1}{12}[/tex].

We are rolling twice, so [tex](\frac{1}{12})^{2} =\frac{1}{144}[/tex].

Answer:

We know that for a human body 9.3% of its total mass is hydrogen.

Now we have a person with a mass of 140 lb.

Then we have that the 100% of the mass is 140lb, the 9.3% of this is hydrogen.

We can write:

9.3% = X

100% = 140lb

We want to find the value of X (mass of hydrogen)

Then we can take the quotient of these two equations to get:

(9.3%/100%) = X/140lb

Now we can isolate the variable X to get:

(9.3%/100%)*140lb = X = 13.02 lb

So this person has about 13.02 lb of hydrogen in his/hers body.

The rational function graphed in this problem is defined as follows:

f(x) = -3(x - 2)/(x² - x - 6).

The vertical asymptotes of the rational function in this problem are given as follows:

x = -2 and x = 3.

Hence the denominator of the rational function is given as follows:

(x + 2)(x - 3) = x² - x - 6.

The zero of the rational function is given as follows:

x = 2.

Hence the numerator is given as follows:

a(x - 2).

In which a is the leading coefficient.

Hence:

f(x) = a(x - 2)/(x² - x - 6).

When x = 0, y = -1, hence the leading coefficient a is obtained as follows:

-1 = -2a/-6

-1 = a/3

a = -3.

Hence the function is:

f(x) = -3(x - 2)/(x² - x - 6).

Answer:

3

Step-by-step explanation:

In this problem we need to kind of write the picture into an equation so the first thing we see are 4 xs on the far left-hand side this is representing "4x" then we see 5 - blocks on the right which represents "-5" because we have 5 minuses then on the other side we see 7 + blocks which represent just "7". After we identify everything in the picture we can write an equation so 4x -5 = 7. Then we solve so we need to separate x on one side and all the other numbers to the other to do that we can move the -5 to the side the 7 is on and because of math when we move a number to another side of the equation we have to switch the sign it has so if it was -5 then on the other side it would be 5 then we add 7 to 5 which would equal 12. Then we are left with 4x = 12 and to keep x on its own side we need to divide 4 from the other side because it is  multiplying on the x side and again we need to switch the sign. then we are left with x=3. Hope this helps!
