I guess it can be 2. If you're not looking for any zeros then the probable answer can most likely be 2
The answer for number one is 104ft^2 not 10.4 and as for number two the link cannot be accesed
Hello from MrBillDoesMath!
Answer:
y = (1/8)x + 5
Discussion:
The slope (m) of y = -8x +4 is -8. The slope of the perpendicular lines is the negative reciprocal of the slope of the first line. That is, the perpendicular slope is -1 /(-8) = + 1/8
y = (1/8) x + b (*)
Also, the perpendicular line passes through the point (0.5) so substituting these values in (*) gives
5 = (1/8)(0) + b => as (1/8) 0 = 0
5 = b
The perpendicular line is given by y = (1/8)x + 5
Thank you,
MrB
Answer:
Around 10 days ( 9.28 days: 9 days 6 hours 43 minutes 12 seconds).
Step-by-step explanation:
Given that 25 gizmos are produced each day, and 75 ¢ are made off of each one, a 174$ repair job will take away money that will need to be paid off.
We can create the following equation by using the amount of gizmos earned per day(x or time) multiplied the money made off of each one(in cents ¢), is equal to the repair job since it will be paid off once it is canceled out.
25x(75¢) = 174$.
Since the money made by each gizmo is in cents and not dollars, it is best to convert this into dollars since the repair job is in this form. Because 100¢ are in each dollar, 75¢ = 75/100 dollars = 3/4 dollars.
3/4 * 25 x = (3/4) * (25x) = (25*3) / 4 = 75/4x
(75/4)x = 174$
(75/4x) * (4/75) = (174$) * (4/75)
x = (174 * 4) / 75
x = 696 / 75
x = 9.28
We are multiplying by the reciprocal (numerator and denominator are switched) since it will make your coefficient 1 which is the variable itself. anything times it's reciprocal is equal to one.
75/4x = 174$
×4 ×4
(cancel out the denominator)
____________
75x = 696$
÷ 75 ÷ 75
(cancel out 75 to get the variable by itself)
___________
x = 696/75
x = 232/25
x = 928/100
x = 9.28
___________
he equation of any horizontal line is
y = .. a number
The x-value has no effect on the equation or on the line at all, as long as y-value stays the same.
In this case the line passes though the point (−8,9)
which tells us that the y-value we want is 9.
Therefore the equation is y=9
