Answer:

4. 3

Step-by-step explanation:

If you multiply 2 by 3 it'll equal to 6. Same with 7 x 3= 21.

You could also subtract 7 from 2 equalling 5 and 21 - 6 equal to 15. Then you would but y over x giving you 15/5. 15 divided by 5 is 3. So both ways you get 3.

Answer:

You are given two points, (0,6) and (3,-3), so use the two-point formula for the equation of a line:

y - y1 = ( (y2 - y1) / (x2 - x1) ) (x - x1)

y - 6 = ( -9 / 3 ) (x - 0)

y - 6 = -3x

y = -3x + 6 This is: y = mx+b

The linear function with the values f(0) = 5 and f(-3) = 6 is [tex]y=\frac{-1}{3}x+5[/tex]

The given functions are:

f(0)  =  5

f(-3)  =  6

That is, x₁ = 0,  y₁ = 5, x₂ = -3, y₂ = 6

The slope of the linear function is calculated as:

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{6-5}{-3-0} \\\\m=\frac{-1}{3}[/tex]

The equation of a line is given as:

Step 6 contains an error. Option C is correct

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

The incorrect step is;

[tex]\rm 1 + cos \theta = 2 sin^2\frac{\theta}{2}[/tex]

The correct step is;

[tex]\rm 1 - cos \theta = 2 sin^2\frac{\theta}{2}[/tex]

Because when you multiply the whole equation the cosΘ will be negative and in the given solution it is positive. Step 6 contains an error.

Step-by-step explanation:

The division is one of the four fundamental arithmetic operations. The time it will take both of them together to paint the house is 6.857 hours.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

Let the area that is needed to be painted be x.

Given that Walter can paint the house by himself in 12 hours. Therefore, we can write the rate at which Water paint is,

Rate = Area needed to be painted / Time

       = x / 12 hours

       = x/12

Further, given that Helen can paint the house by herself in 16 hours. Therefore, we can write the rate at which Helen paint is,

Rate = Area needed to be painted / Time

       = x / 16 hours

       = x/16

Now, the rate at which they both will paint or the area that they will cover in an hour is,

Rate = (x/12) + (x/16)

       = (4x/48) + (3x/48)

       = (4x + 3x)/48

       = 7x / 48

Furthermore, the time it will take both of them together to paint the house is,

Time = Area needed to be painted / Rate

        = x / (7x/48)

        = 48/7 hours

        = 6.857 hours

Hence, the time it will take both of them together to paint the house is 6.857 hours.

Answer:

1/5 I really hope that helps have a good day

Answer:

Let's identify what we know and what we are looking for. To start off, the question states that there is a flat rate of 500. This is the y intercept, because you start off with 500. It also states that it charges a fee of 50 per hour, which is your slope. So what we have now is y=50x+500. We know that A is asking how much it will be for 20 hours. We simply plug 20 into x, so we do y=50(20)+500 which gives 1500. For C, we repeat the same step and just plug in 50.

11/20 is the answer

Answer:

(-1, 3), (-5, -5), and (1, 2)

Step-by-step explanation:

To make this easier to solve, simplify the inequality:

12x - 3y < 12

= -3y < -12x + 12 (subtract 12x)

= 3y > 12x - 12 (multiply by -1, switch the inequality because it was a multiplication by a negative number)

= y > 4x - 4 (divide by 3)

Now, just go through each point and see if they are correct after you plug them into the inequality and solve:

(-1, 3): 3 > -8? yes

(-5, -5): -5 > -24? yes

(0, -4): -4 > -4? no

(1, 2): 2 > 0? yes

(4, 4): 4 > 12? no

(3, 8): 8 > 8? no

In conclusion, the points (-1, 3), (-5, -5), and (1, 2) fit the inequality.

Answer:

A = 25π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( where r is the radius )

Here diameter = 10, thus r = 10 ÷ 2 = 5, then

A = π × 5² = 25π cm²

Answer: [tex]1\dfrac13[/tex] cups of pineapple juice .

Step-by-step explanation:

Equation of direct proportion between x and y:

[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]

As per given,

Let x = quantity of pineapple juice and y = quantity of orange juice.

[tex]x_1=\dfrac13\[/tex]  , [tex]y_1=\dfrac34[/tex] ,  [tex]y_2=3[/tex]

Put these values in an equation we get

[tex]\dfrac{\dfrac13}{\dfrac34}=\dfrac{x_2}{3}\\\\\Rightarrow\ \dfrac{4}{9}=\dfrac{x_2}{3}\\\\\Rightarrow\ x_2=3\times\dfrac{4}{9}=\dfrac{4}{3}\\\\\Rightarrow\ x_2=1\dfrac13[/tex]

Hence, he needs [tex]1\dfrac13[/tex] cups of pineapple juice .

Answer:

He needs 1 and 1/3 cups of pinapple juice when he uses 3 cups of orange juice.

Step-by-step explanation:

Orange Juice:

3 cups / 3/4 cups = 12/3= 4

Pineapple Juice:

1/3 × 4 = 4/3 cups= 1 1/3 cups

angles on a straight line add up to 180 degrees

Answer: d) -310pi

Step-by-step explanation:

Instantaneous Rate of Change

Is the change in the rate of change of a function at a particular instant. It's the same as the derivative value at a specific point.

The surface area of a cylinder of radius r and height h is:

[tex]A=2\pi r^2+2\pi r h[/tex]

We need to calculate the rate of change of the surface area of the cylinder at a specific moment where:

The radius is r=8 mm

The height is h=3 mm

The radius changes at r'=-9 mm/hr

The height changes at h'=+2 mm/hr

Find the derivative of A with respect to time:

[tex]A'=2\pi (r^2)'+2\pi (r h)'[/tex]

[tex]A'=2\pi 2rr'+2\pi (r' h+rh')[/tex]

Substituting the values:

[tex]A'=2\pi 2(8)(-9)+2\pi ((-9) (3)+(8)(2))[/tex]

Calculating:

[tex]A'=-288\pi +2\pi (-27+16)[/tex]

[tex]A'=-288\pi +2\pi (-11)[/tex]

[tex]A'=-288\pi -22\pi[/tex]

[tex]A'=-310\pi[/tex]

Answer: Sara bought billboards with 4 lines for $20 (the quantity is 7)

We have to take the total cost (t) and divide that buy the 6 lines billboards and the 4 line billboards.

So, let's divide $140 by 20 and 30 (the cost for each type of billboard).

$140 ÷ 30 = 4.6

This can not be the answer because Sara bought 7 billboards, not 4.6

$140 ÷ 20 = 7

So, the answer is Sara bought billboards with 4 lines for $20.

Hope this helps you!
