84 grams.
What is the final mass of the solid?

Answer: h(x) = 23

Step-by-step explanation:

Plug x in the equation

h(x) = 4(7) - 5

h(x) = 28 - 5

h(x) = 23

Answer:

The bamboo grows at a rate of 90cms a day

Step-by-step explanation:

1/3 of a day = 30cms

3/3 of a day = 30 * 3 cms = 90 cms

Hope this helps, Thank you!

The bamboo grows at a rate of 3.75 centimeters per hour.

A division is a process of splitting a specific amount into equal parts.

To find the rate at which the bamboo grows, we can use the formula:

rate = distance/time

Here, the distance is 30 centimeters, and the time is 1/3 of a day, which is equivalent to 8 hours. Therefore, we have:

rate = 30 centimeters / 8 hours

Simplifying, we get:

rate = 3.75 centimeters per hour

Therefore, the bamboo grows at a rate of 3.75 centimeters per hour.

Answer:

Step-by-step explanation:

{z - some integer}

2z+1  - the smallest number

7(2z+1)  - seven times the smallest number

2z+1+2=2z+3  - the middle number

2z+3+2 = 2z+5 - the largest number

2(2z+5) - twice the largest number

7(2z+1) + 2(2z+5)  - the sum of 7 times the smallest and twice the largest

7(2z+1) + 2(2z+5)   = -91

14z + 7 + 4z + 10 = -91

              -17              -17

      18z   = -108

       ÷18        ÷18

        z = -6

2z+1 = 2(-6)+1 = -12 + 1 = -11  

2z+3 = 2(-6)+3 = -12 + 3 = -9

2z+5 = 2(-6)+5 = -12 + 5 = -7

Answer:

The smaller Number = 15

The larger number = 67

Step-by-step explanation:

Let

The smaller number = x

The larger number = 5x - 8

The sum = 82

(5x - 8) + x = 82

5x - 8 + x = 82

6x - 8 = 82

Add eight to both sides

6x - 8 + 8 = 82 + 8

6x = 90

Divide both sides by 6

x = 90/6

= 15

Therefore,

The smaller number = x = 15

The larger number = 5x - 8

= 5(15) - 8

= 75 - 8

= 67

Step-by-step explanation:

f(x) = 2(x+4)(x+2)

= 2[x² + 6x + 8]

= 2x² + 12x + 16

thats the estimate

Answer:

Answer:

The average speed is 1 meter per second

Step-by-step explanation:

Here, we want to calculate average speed

Mathematically;

Average speed = Total distance/Total time

In this case, the total distance traveled = 1400-200 = 1,200 meters

Total time taken = 20 minutes

Since 60 seconds = 1 minute; 20 minutes is 20 * 60 = 1200 seconds

So average speed = 1200 meters/1200 seconds = 1 meter/second

Answer:

x < -2

Step-by-step explanation:

So if you want to find x we want to simplify the equation first:

14x - 2 > 20x + 10

We should subtract 10 on both sides first:

14x - 12 > 20x

And then subtract 14x from both sides:

- 12 > 6x

Then we want to divide 6 from both sides:

-2 > x

There ya go:

x is less than -2; x < -2

Answer:

y = -2x + 2

Step-by-step explanation:

I need the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5.

Write the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to 2x + y = -5. Include your work in your final answer.

"parallel"means "same slope".

let's find, first, the slope of the given line: rewrite the equation in standard form,

that is -

y=-2x-0.5

This means the slope of the required line is "-2"

Now, just plugin the numbers into standard equation:

y=slope*x+intercept

you'll end up with

y=-2x+2

The effect on the graph of f(x) when it transformed to g(x) is the graph of f(x) is shifted 9 units up.

The correct answer is an option (A)

"It is a set of points which satisfies given function."

For given question,

We have been given two functions [tex]f(x)=\frac{1}{x}[/tex] and [tex]g(x)=\frac{1}{x}+9[/tex]

We know that if function f(x) is transformed to f(x) + k where k > 0, then it translates upward k units.

The function g(x) is f(x) + 9

This means, the graph of function g(x) is the graph of function f(x) shifted 9 units up.

Therefore, the effect on the graph of f(x) when it transformed to g(x) is the graph of f(x) is shifted 9 units up.

The correct answer is an option (A)
