Answer:
x-15
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
85 divided by 5 in distributive property
85 can be break into 80 and 5
80+5 is 85
Now we divide each term by 5

Denominator 5 is distributed 5 inside the numerator

17 is the final answer
Answer:
Yes
Step-by-step explanation:
The definition of a rational number is a number that can be represented as a fraction. Since 56/7 is a fraction it must be a rational number. An irrational number is a number that cannot be represented as a fraction because it never ends and repeats without a pattern forever. An example of this is pi because pi can never exactly be represented as a fraction.
Answer: r>13
Step-by-step explanation:
The sign is less than so r +8 has to be 20 or less.
a) x-intercepts (where it passes through the x-axis) are: 0.05, 0.745, 0.8, 1.45, 1.55, 2.2
The x-intercepts represent when height = 0 and y-intercepts represent when time = 0
b) The graph is positive when height is positive: [0.05, 0.745] U [0.8, 1.45] U [1.55, 2.2]
c) The graph is negative when height is negative: [0, 0.05] U [0.745, 0.8] U [1.45, 1.55] U [2.2, ∞)
d) The average rate of change is the slope (rise/run) between the coordinates when x = 0.75 <em>(y = -5)</em> and when x = 1.125 <em> (y = 1.7). </em>
slope =
=
= 6
