Which type of graph is useful for demonstrating how something changes or fluctuates in value over time?

Line graphs (or line charts) are best when you want to show how the value of something changes over time, or compare how several things change over time relative to each other. Whenever you hear that key phrase “over time,” that's your clue to consider using a line graph for your data.

One bricklayer can build a wall in 6 hours. Another bricklayer could build the same wall in 4 hours. If they work together, how

Natasha2012 [34]

Answer:

they work together, it will take 2.4 hours to build the wall.

Step-by-step explanation:

One bricklayer can build a wall in 6 hours.

One hour work = $\frac{1}{6}$

Another bricklayer can build the same wall in 4 hours.

One hour work = $\frac{1}{4}$

They can together, how long will take them to build the wall.

Let's take "t" the time taken to build the wall.

The sum of their work rate = 1 (To build the wall)

$\frac{t}{6} + \frac{t}{4} = 1$

Now we have to solve this equation. Take LCD of 6 and 4.

The LCD (least common divisor) of 6 and 4 is 12.

$\frac{2t + 3t}{12} = 1$

5t = 12*1

5t = 12

Dividing both sides by 5, we get

t = $\frac{12}{5}$

t = 2.4 hours.

So, they work together, it will take 2.4 hours to build the wall.

The product of 8/9 and the sum of a number and – 4 is less than or equal to 64.

Fiesta28 [93]

Answer:

$x\leq 76$

Step-by-step explanation:

Let x = unknown number

$\implies \dfrac89 \times (x-4)\leq 64$

$\implies \dfrac{8(x-4)}{9}\leq 64$

Multiply both sides by 9:

$\implies 8(x-4)\leq 576$

Expand brackets:

$\implies 8x-32\leq 576$

Add 32 to both sides:

$\implies 8x\leq 608$

Divide both sides by 8:

$\implies x\leq 76$

<h3>Slope = 10</h3><h3>y intercept at (0,750)</h3><h3>x intercept at (-75, 0)</h3>

=====================================

Explanation:

The function f(x) = 10x+750 is the same as y = 10x+750

It is in the form y = mx+b where m = 10 is the slope and b = 750 is the y intercept. So that covers the first two parts of the answer.

The x intercept is found by replacing y with 0, then solving for x like shown below

y = 10x + 750

0 = 10x + 750

10x + 750 = 0

10x = -750 ....... subtract 750 from both sides

x = -750/10 .... divide both sides by 10

x = -75

So x = -75 plugged into the function leads to y = 0

Meaning that x = -75 and y = 0 pair up together to get the point (-75,0) which is the x intercept. This is the location where the line crosses the x axis.
