b=2x^2(x-5) divided by 10x solve b if x=10​

Answers

Answer:

answer is 10

Step-by-step explanation:

2x^2(x-5) /10x

x=10

so,

=2*10^2 (10-5) / 10*10

=2*100(10-5) /100

=200*5 / 100

=1000/100

=10

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of b when x = 10 is 10.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

b = 2x² (x - 5) ÷ 10x

When x = 10 find b.

Now,

b = (2x² (x - 5))/ 10x

Substitute x = 10

b = 2 x 10² ( 10 - 5) / 10 x 10

b = 200 x 5 / 100

b = 10

Thus,

The value of b when x = 10 is 10.

Graph the equations
Y=400+50x
Y=300+25x

1.) from the graph at what time will the they have the same height

I’ll give u brainlist pls help

Answers

Answer:

We conclude that, at 4 minutes, both will have the same height which is 200 feet.

Step-by-step explanation:

Given the system of equations

[tex]y=400+50x[/tex]

[tex]y=300+25x[/tex]

Important Tip:

The point of intersection of the two lines would give us the point at which both have the same height.

Graphing the system of equations

The graph of the equation y = 400 + 50x

First, determine the y-intercept of the equation y = 400 + 50x by substituting x = 0

[tex]y = 400 + 50x[/tex]

[tex]y = 400 + 50(0)[/tex]

[tex]y = 400 + 0[/tex]

[tex]y = 400[/tex]

Thus, we determine that the ordered pair (0, 400) represents the y-intercept of the equation y = 400 + 50x.

Next, determine the x-intercept of the graph of the equation y = 400 + 50x by substituting y = 0

[tex]y = 400 + 50x[/tex]

[tex]0=400+50x[/tex]

switch sides

[tex]400+50x=0[/tex]

Subtract 400 from both sides

[tex]400+50x-400=0-400[/tex]

Simplify

[tex]50x=-400[/tex]

Divide both sides by 50

[tex]\frac{50x}{50}=\frac{-400}{50}[/tex]

Simplify

[tex]x=-8[/tex]

Thus, we determine that the ordered pair (-8, 0) represents the x-intercept of the equation y = 400 + 50x.

Important Tip:

The point at which the graph crosses the y-axis is called the y-intercept. The point at which the graph crosses the x-axis is called the x-intercept.

The red graph on the diagram represents the equation y = 400 + 50x having the y-intercept (0, 400) and x-intercept (-8, 0)

Please check the attached diagram.

The graph of the equation y = 300 + 25x

Now, determine the y-intercept of the equation y = 300 + 25x by substituting x = 0

[tex]y = 300 + 25x[/tex]

[tex]y = 300 + 25(0)[/tex]

[tex]y = 300 + 0[/tex]

[tex]y = 300[/tex]

Thus, we determine that the ordered pair (0, 300) represents the y-intercept of the equation y = 300 + 25x.

Next, determine the x-intercept of the graph of the equation y = 300 + 25x by substituting y = 0

[tex]y=300+25x[/tex]

[tex]0 = 300 + 25x[/tex]

switch sides

[tex]300+25x=0[/tex]

Subtract 300 from both sides

[tex]300+25x-300=0-300[/tex]

Simplify

[tex]25x=-300[/tex]

Divide both sides by 25

[tex]\frac{25x}{25}=\frac{-300}{25}[/tex]

Simplify

[tex]x=-12[/tex]

Thus, we determine that the ordered pair (-12, 0) represents the x-intercept of the equation y = 300 + 25x.

The blue graph on the diagram represents the equation y = 300 + 25x having the y-intercept (0, 300) and x-intercept (-12, 0)

Please check the attached diagram.

Analyze the POINT OF INTERSECTION:

As we already know that the point of intersection of the two lines would give us the point at which both have the same height.

The diagram indicates that:

at x = -4, the value of y = 200.

It is the point where both lines meet.

Thus, the point of intersection of the two lines is:

(x, y) = (-4, 200)

Conclusion:

As x represents the time in minutes and y represents the height in feet.

Thus, we conclude that at x = 4 minutes, both will have the same height i.e. y = 200 feet

Therefore, we conclude that, at 4 minutes, both will have the same height which is 200 feet.

What expression is equivalent to 9(3x + 8)? *

Answers

Step-by-step explanation:

This is what it is equal to:

9×3x=27x

9×8=72

Therefore it will be:

[tex]27x + 72[/tex]

hope it helps!

Answer:

27x+72

Step-by-step explanation:

You have to use the distributive property to simplify the expression. Therefore, you have to  multiply both terms inside the parentheses.

1. 9*3x=27x

2. 9*8=72

They could not be added together, as they are not like-terms. So, you just write it down as 27x+72.

Step-by-step explanation:

1, 2. The area of each triangle is given by the formula ...

  A = (1/2)bh . . . . . for base b and height h

The area of the given triangle is ...

  A = (1/2)(7 in)(15 in) = 105/2 in² = 52.5 in²

Triangles 1 and 2 have the same dimensions, so have the same area.

  Figure 1 area: 52.5 in²

  Figure 2 area: 52.5 in²

__

3. The area of the semicircle is given by the formula ...

  A = (1/2)πr² . . . . for a semicircle of radius r

This semicircle has a radius of 7 in, so an area of ...

  A = (1/2)(3.1416)(7 in)² ≈ 76.97 in²

  Figure 3 area: 76.97 in²

__

The total area is the sum of these:

  52.5 in² + 52.5 in² +76.97 in² = 181.97 in²

  Composite Figure area: 181.97 in²

_____

Comment on decimal digits

We cannot tell your rounding requirements. Here, we have rounded to the nearest hundredth. If you use the value 3.14 for pi, then your areas for the semicircle and composite figure will end in .93, not .97.
