What is the equation of the line in slope-intercept form?
Answers
Answer:
The equation of the line in slope-intercept form is:
[tex]\:y=-\frac{1}{6}x\:+\:4[/tex]
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slope b is the y-interceptGiven the points on the line graph
(0, 4) (3, 3.5)Determining the slope between (0, 4) and (3, 3.5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{3.5-4}{3-0}[/tex]
[tex]m=\frac{\frac{7}{2}-4}{3-0}[/tex]
[tex]m=-\frac{1}{6}[/tex]
Thus, the slope of the line = m = -1/6
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 4
Thus, the y-intercept b = 4
now substituting b = 4 and m = -1/6 in the slope-intercept form
[tex]y = mx + b[/tex]
[tex]\:y=-\frac{1}{6}x\:+\:4[/tex]
Therefore, the equation of the line in slope-intercept form is:
[tex]\:y=-\frac{1}{6}x\:+\:4[/tex]
A hardware store rents vacuum cleaners that customers may use for part or all of a day, up to 12 hours, before returning. The store charges a flat fee plus an hourly rate. Write a linear function f for the total rental cost of a vacuum cleaner.
Answers
Answer:
Step-by-step explanation:
Let x represents the amount that the customer pays per hour
for renting the vacuum cleaner before returning it.
Let y represent the flat rate that the store charges a customer for renting the vacuum cleaner.
Let F represent thea amount that the store charges a customer for renting the vacuum cleaner for x hours.
A linear function F for the total retail cost of a vacuum cleaner would be
F(x) = x + y
If the customer rents it for n hours, the total amount becomes
F(x) = nx + y

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
A fraction represents a part of a whole.
We need to write 79% as a fraction or mixed number in simplest form.
79% we will convert to decimal number by dividing with 100.
As we know percentage is a hundredth part.
79% is the hundredth part of 79
79/100=0.79

abdul purchases two pairs of goggles priced the same, as well as a bottle of sun screen. The sunscreen was $12 and represents 30% of the total. How much is the purchase total?
Answers
Answer:
$40
Step-by-step explanation:
We can call the total x.
30% = 3/10, so $12 = 3/10 of the total.
This means that 12 = 3/10 of x, or 12 = 3/10 * x.
Solving,
12 = 3/10 * x
multiply both sides by 10 to get rid of the fraction
120 = 3 * x
divide both sides by 3 to get x, the total, by itself
40 = x
This means that the total is $40.
Answer:
$40Step-by-step explanation:
Let the total be x
30% of total is $120.3x = 12x = 12/0.3x = 40Total is $40
