Hello!
Interval notation is written using brackets or parentheses. Brackets mean that the value of the corresponding side is equal to the function. Parentheses are the opposite of brackets in this case, and it is not part of the equation.
I will post the graph of this equation below.
Therefore, the domain of this equation in interval notation is (-∞, 6/7).
Note that it is parentheses not brackets. The graph does not go past 6/7, and infinity is not a number, it is a concept.
Answer:
Stefan originally spent $110
Stefen made $33 by selling the bicycle and helmet to jin.
Step-by-step explanation:
let ,
the original cost of bicycle and helmet for Stefan be 'x'
now,
total cost for Jin of bicycle and helmet = 126 + 17
= 143
also, total cost for Jin = 130% of original cost for Stefan
⇒ 143 =
⇒ x = 110.
hence,
profit made by Stefan = total cost for Jin - original cost for Stefan
= 143 - 110
= 33
Answer:
Step-by-step explanation:
We want the equation of a line that is parallel to which also passes through (-7, 1).
Since the new line is parallel, it must have the same slope as the original line.
The slope of the original line is 6.
Hence, the slope of our new line must also be 6.
We know that the slope is 6.
And it passes through the point (-7, 1).
So, we can use the point-slope form:
Where m is the slope and (x₁, y₁) is a point.
Substitute:
Simplify:
Distribute:
Add 1 to both sides. Hence, our equation is:
