We know that 1 mm=0.01 dm
75 mm=0.75 dm
choice D
Answer:
Bruno is correct x=1
Step-by-step explanation:
-3(2x+6)+25=1
-6x-18+25=1
-6x+7=1
-6x=-6
1=x
Using linear functions, it is found that Rowan and Kennedy will have read the same number of pages in 10 minutes.
What is a linear function?
- A linear function is modeled by:

In which:
- a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
For Rowan, we have that:
- He has already read 20 pages, hence the y-intercept is
.
- He reads 1.5 pages per minute, hence the slope is

Then:

For Kennedy, we have that:
- He has already read 25 pages, hence the y-intercept is
.
- He reads 1 page per minute, hence the slope is

Then:

They will have read the same number of pages after x minutes, for which:

Then:

Answer:
i need more information about the question... i suggest googleing it
Step-by-step explanation:
First, you need to change it from standard form to slope-intercept form. To do this, you have to add 3x to both sides. Now that y is by itself, divide by 5 on both sides. Your equation should now be y=3x+3. Then, graph the points. Your x-intercept should be at (-5,0) and your y- intercept should be at (0,3).
