Answer:
A: (-1,0)
B: (1,1)
C: (5,3)
(0,½)
(7,5) doesn't lie on the line
Step-by-step explanation:
Slope: (3-1)/(5-1) = ½
y = ½x + c
0 = ½(-1) + c
c = ½
y = ½x + ½
(0,½) is on the line
y = ½x + ½
Check for (7,5)
5 = 7/2 + 1/2
5 = 4 is a false statement
Answer:
if f(x) = 3x+4, the rate of change is 4.
if f(x) = 2x+7, the rate of change is 2.
Step-by-step explanation:
We know that the average rate of change over the interval x=0 to x=8 is:
(f(x2) - f(x1))/x2-x1
Where:
x2 = 8
x1 = 0
if f(x) = 3x+4
so f(8)=3(8)+4 = 28
f(0)=3(0)+4 = 4
Then: (f(x2) - f(x1))/x2-x1 = (28 - 4)/8-0 = 24/8 = 3
On the other hand, if f(x) = 2x+7
f(8) = 2(8)+7 = 23
f(0) = 2(0)+7 = 7
Then: (f(x2) - f(x1))/x2-x1 = Then: 23 - 7/8-0 = 16/8 = 2
Answer:
Size 9
Step-by-step explanation:
The range is the highest value - the lowest value.
If the range is three, therefore the highest value - lowest value is 3
If 2 people in the family wear size 6, we can count that as 1 value. Since the question says that his shoe size can't be 3, so we let x be the number with the higher value.
x - 6 = 3
x = 9
Therefore Lee's shoe size is 9
Answer: D) w = 9 feet
Work Shown:
That points us to the final answer choice D.
It would be 20.15 because the 65% of 31 is 20.15
