Slope could be found in the "m" variable of the equation: y = mx + b
You would see that 7 would be in the place of the variable "m"
Therefore, your slope, or rate of change, would be 7
Answer: 7

Answer:
- gradient is 4.
- y-intercept is -5.
- No.
Step-by-step explanation:
1. In order to find the gradient of equation, you have to make it into slope-form equation y = mx + b :
So m represents gradient. In this question, m is 4.
2. Make it into slope-form equation :
In this question, y-intercept is b which is -5.
3. You have to substitute x-coodinate into the equation to see whether it is equal to y-coordinate :
Answer:
2048$ in the account
Step-by-step explanation:
Answer:
1( first page of volume 1) + 900 (900 book of 100 pages) + 1 (last page of the book)
Answer: 28.26
Step-by-step explanation:
What your looking for is called the annulus (or the difference of two concentric circles). You can find the annulus by subtracting the area of the inner circle from the area of the outer circle. Volume of a circle= πr²
You are given the diameter in these problems, so you need radius.
For the first circle (8 in one) :
8/2=4 r=4
A=3.14(4)²
A=50.24
For the second one (10 in one) :
10/2=5 r=5
A=3.14(5)²
A=78.5
To find the measure of the annulus, you subtract those numbers, getting 28.26
