Answer:
Step-by-step explanation:
Let
x ----> the number of hours
y ---> the total cost of renting a jet ski in dollars
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
we have the ordered pair (3,265)
substitute in the linear equation
solve for b
----> fee for a lesson on how to use the jet ski
substitute
Answer: $8.80 for one hour of mowing and $40.50 for 5 hours of babysitting
Step-by-step explanation:
You need to get x alone on one side. You need to divide 1/2 on both sides which makes 13 a 26. x<26
1.No error , he divided by 16 in the 2 sides .
2.no error ,he made sure that 16/16 is one while d/16 remains
3.no error , he square rooted both sides
4.error, as the root gives one positive value and one negative value not only a positive value ,the answer should have been t=+-(d/4)
5.error,he disturbed the whole equation by rooting d only he should have rooted both sides
It is the line of symmetry of a parabola and divides a parabola into two equal halves that are reflections of each other about the line of symmetry.
It intersects a parabola at its vertex.
It is a vertical line with the equation of x = -b/2a.
