The solution to the linear equation is determined as 5.

The equation to solve is:

3x - 8 = 7

To solve for x, you can follow these steps:

Step 1: Add 8 to both sides of the equation to isolate the term with x on one side:

3x - 8 + 8 = 7 + 8 (combine constants here)

This simplifies to:

3x = 15

Step 2: Divide both sides of the equation by 3 to solve for x:

3x/3 = 15/3

This simplifies to:

x = 5

Taking the quotient between the total volume and the flow rate, we can see that the correct option is D.

We know that water flows at a rate of 1.5*10^4 gallons per second. We know that 6.525*10^6 gallons flowed while Jeremy was watching, then the time that he has been watching is the quotient between these values, we will get:

time = ( 6.525*10^6)/(1.510^4) seconds =  (652.5/1.5) second = 435 seconds

We know that 60 secons = 1 minute, then:

Answer:

C

Step-by-step explanation:

Recall the point-slope form of a linear equation:

[tex]y-y_{1}=m(x-x_{1} )[/tex]

Where y1 and x1 are points from the ordered pair (x1, y1),

and m represents the slope of the line.

We are given that the point (-5, 7) belongs to the graph. Here, the x-coordinate is -5, and the y-coordinate is 7.

Let's plug in these values, were x1=-5, and y1=7:

[tex]y-y_{1}=m(x-x_{1} )=\\y-7=m(x-(-5))=\\y-7=m(x+5)[/tex]

We are also given that the slope is -4/3.

In other words, m=-4/3. Let's plug this value in:

[tex]y-7=m(x+5)=\\y-7=-\frac{4}{3}(x+5)[/tex]

Thus, the answer is C.

Answer:

C

Step-by-step explanation:

The point-slope form of the equation of a line passing through the point (x1, y1)with a slope of m is given by:

y - y1 = m(x - x1)

To find the equation of the line passing through the point (-5, 7)with a slope of -4/3, we substitute m = -4/3, x1 = -5, and y1 = 7 into the point-slope form equation:

y - 7 = (-4/3)(x - (-5))

Simplifying this equation, we get the final result in slope-intercept form:

y = (-4/3)x + (17/3)

Therefore, the equation of the line in a point-slope form that passes through (-5,7) and has a slope of -4/3 is y + 7 = -4/3 (x + 5)

The volume of the other solid (Solid B) is 3456 cubic feet.

Solid A has edges of 4 feet, and its volume is given as 16 cubic feet. Solid B has edges of 24 feet.

Since the solids are similar, they have the same shape, and their corresponding lengths are proportional. To find the ratio of their corresponding lengths, we can divide the length of an edge of Solid B by the length of an edge of Solid A:

Ratio = (length of edge of Solid B) / (length of edge of Solid A)

Ratio = 24 feet / 4 feet

Ratio = 6

Now that we have the ratio of their corresponding lengths, we can find the ratio of their volumes. The ratio of the volumes of similar solids is the cube of the ratio of their corresponding lengths:

Volume ratio = (length ratio)³

Volume ratio = 6³

Volume ratio = 216

Now we can use the volume ratio to find the volume of Solid B:

Volume of Solid B = (Volume of Solid A) × (Volume ratio)

Volume of Solid B = 16 ft³ × 216

Volume of Solid B = 3456 ft³

So, the volume of the other solid (Solid B) is 3456 cubic feet.

Answer:

The solutions to the equation x^2 = 4x + 41 are x = 2 + 2sqrt(11) and x = 2 - 2sqrt(11).

Step-by-step explanation:

To solve the equation x^2 = 4x + 41, we can first rearrange it as x^2 - 4x - 41 = 0.

Next, we can use the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a, b, and c are the coefficients of the quadratic equation. In this case, a = 1, b = -4, and c = -41.

Substituting these values into the formula, we get:

x = (4 ± sqrt((-4)^2 - 4(1)(-41))) / 2(1)

Simplifying:

x = (4 ± sqrt(176)) / 2

x = (4 ± 4sqrt(11)) / 2

x = 2 ± 2sqrt(11)

Therefore, the solutions to the equation x^2 = 4x + 41 are x = 2 + 2sqrt(11) and x = 2 - 2sqrt(11).

The quotient of the expression 5x^2/7÷10x^3/21 is 3/(2x)

From the question, we have the following parameters that can be used in our computation:

5x^2/7÷10x^3/21

Assume that no denominator has a value of 0, we have

5x^2/7÷10x^3/21 = 5x^2/7 ÷ 10x^3/(7 * 3)

Express as products

So, we have the following representation

5x^2/7÷10x^3/21 = 5x^2/7 * (7 * 3)/10x^3

When the factors are evaluated, we have

5x^2/7÷10x^3/21 = 5 * 3/10x

So, we have

5x^2/7÷10x^3/21 = 15/10x

Given statement "3-6 You can determine the slope of a roof using a flat board, a bubble level and a ruler,or a sight card can be used." is true. Because flat board, a bubble level and a ruler,or a sight card methods are commonly used to determine the slope of a roof, and both are effective.

Determining the slope of a roof is an important task for many construction and roofing projects.

One method to determine the slope of a roof is to use a flat board, a bubble level, and a ruler.

First, place the flat board horizontally on the roof surface, and use the bubble level to make sure it is level.

Then, measure the distance between the bottom of the board and the roof surface at the point where the board intersects with the roof using the ruler. This distance is the rise.

Next, measure the distance from the point where the board intersects with the roof to the end of the board using the ruler. This distance is the run. Finally, divide the rise by the run to get the slope.

Another method to determine the slope of a roof is to use a sight card. A sight card is a specially designed tool that can help to measure the angle of a slope or pitch. The sight card is held at the bottom of the roof and lined up with a known vertical or horizontal line, such as the edge of a building.

The slope of the function f(x) = -3x^2 +11 at any value of x is given by 6x.

The definition of derivative is given by the limit as h approaches 0 of [f(a+h) - f(a)] / h,

where f(x) is a function and a is a fixed value of x.

To find the slope of the function[tex]f(x) = -3x^2 +11[/tex]  at any value of x, we need to use this definition of derivative.
So, let's plug in f(x) = -3x^2 +11 and a = x into the formula.

This gives us:
lim as h approaches 0 of [tex][-3(x+h)^2 + 11 - (-3x^2 + 11)] / h[/tex]
Simplifying this expression, we get:
lim as h approaches 0 of [tex][-3x^2 - 6hx - 3h^2 + 11 + 3x^2 - 11] / h[/tex]
Combining like terms, we get:
lim as h approaches 0 of [tex][-6hx - 3h^2] / h][/tex]
Factoring out an h from the numerator, we get:
lim as h approaches 0 of [-h(6x + 3h)] / h
Canceling out the h in the numerator and denominator, we get:
lim as h approaches 0 of 6x + 3h
Now, we can plug in h = 0 to find the slope of the function at any value of x:
