Answer:
5 hours 20 minutes
Step-by-step explanation:
Distance traveled to be 20 miles apart
180 - 20 = 160 miles
Combined speed
14 + 16 = 30 mph
time = distance / speed
t = 160/30
t = 5 1/3 hours
t = 5 hours 20 minutes
Answer:
5 hours and 20 minutes
Step-by-step explanation:
it will take them 5 hours and 20 minutes.

What is the algebraic inverse of the function? f(x) = 2x -6 please include steps
9514 1404 393
Answer:
f^-1(x) = (x +6)/2
Step-by-step explanation:
The inverse function is found by solving ...
x = f(y)
Here that is the solution to ...
x = 2y -6
x +6 = 2y . . . . . add 6
(x +6)/2 = y . . . divide by the coefficient of y
The inverse function is ...
f^-1(x) = (x +6)/2
Helpp the topic is about limits
Since we want to find the value of k where the limit exists, set both equations equal to each other. Then substitute x = -1 in for each equation to find k.
[tex]kx - 3 = {x}^{2} + k[/tex]
1. Set both equations equal.
[tex] - k - 3 = 1 + k[/tex]
2. Substitute x = -1.
[tex] - 3 = 1 + 2k[/tex]
3. Solve for k by adding k to both sides. Continue the process of solving the equation.
[tex] - 4 = 2k[/tex]
[tex]k = - 2[/tex]
Thus, k = -2. Check by graphing the function.

Solve the inequality x/5-3<0
Answer:
x < 15
Step-by-step explanation:
[tex]\frac{x}{5}[/tex] - 3 < 0 ( add 3 to both sides )
[tex]\frac{x}{5}[/tex] < 3 ( multiply both sides by 5 to clear the fraction )
x < 15
If you solve an equation by graphing each side separately, which of these is the solution to the equation?
A. the x-coordinate of the intersection point
B. the y-coordinate of the intersection point
C. both the x- and the y-coordinates of the intersection point
D. There is only a solution if the lines are identical.
9514 1404 393
Answer:
A. the x-coordinate of the intersection point
Step-by-step explanation:
If you are solving ...
f(x) = g(x)
the solution is one or more values of x. That is still true if you rewrite the equation to be a system of equations ...
y = f(x)
y = g(x)
The value of y tells you the value of each side of the original equation where the solution causes the functions to be equal. That is largely irrelevant. What you're looking for is the value of x.
The solution is the x-coordinate of the intersection point.

Find the length of x of the side of the larger triangle. (Assume that the two triangles are similar, and use the fact that corresponding sides of similar triangles are proportional)
X=
Similar triangles may or may not be congruent
The value of x that makes both triangles similar is 4.5
The equivalent ratio of both triangles is:
[tex]\mathbf{2 : 1 = 9 : x}[/tex]
Express the above equivalent ratio as a fraction
[tex]\mathbf{\frac 12= \frac x9 }[/tex]
Multiply both sides of the fraction by 9
[tex]\mathbf{\frac 12\times 9 = \frac x9 \times 9 }[/tex]
Cancel out common factors
[tex]\mathbf{\frac 12\times 9 = x}[/tex]
Divide 12 by 9
[tex]\mathbf{4.5 = x}[/tex]
Rewrite the above expression as:
[tex]\mathbf{x = 4.5 }[/tex]
Hence, the value of x is 4.5

No doubt you have been shown at least a couple of different strategies for multiplying mixed numbers.
1) Use the distributive property.
10(3 1/6) = 10(3) +10(1/6) = 30 +10/6 = 30 +5/3 = 30 + 1 2/3 = 31 2/3

2) Use improper fractions.
10(3 1/6) = 10(19/6) = 190/6 = 95/3 = 31 2/3
A function f is defined by f(x) = 3x + 1. Find
a. f(0)=
c. f(2)=
F(-2)
Answer:
a) f(0)=3*0+1 =0+1= 1
b)f(2)=3*2+1=6+1=7
c)f(-2)=3*(-2)+1=-6+1=-5
Answer:
Step-by-step explanation:
f(x) = 3x+1
f(0) = 3x + 1
f(0) = 3*0+1
f(0) = 0+1
f(0) = 1
f(2) = 3x+1
f(2) = 3*2+1
f(2) = 6+1
f(2) = 7
f(-2) =3x+1
f(-2) =3*-2+1
f(-2) = -6+1
f(-2) = -5
f(-2) =

Assume this is a partial list of financial highlights from a Best Buy annual report (dollars in millions):
Net sales
2020 - $40,580
2019 - $35,475
Earnings before taxes
2020 - $2,291
2019 - $1,313
Net earnings
2020 - $1,378
2019 - $921
Find horizontal analysis and vertical analysis.
Value of Horizontal Analysis:
⇒ Net sales = 14.4%
⇒ Earnings before taxes = 74.4%
⇒ Net earnings = 49.6%
Value of Vertical Analysis;
⇒ Net sales = 100%
⇒ Earnings before taxes = 5.6%
⇒ Net earnings = 3.4%
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Now, We can find as;
Horizontal Analysis:
Here, Calculate the dollar change by subtracting the previous year's figure from the current year's figure for each item:
Net sales = $40,580 million - $35,475 million
= $5,105 million increase
Earnings before taxes = $2,291 million - $1,313 million
= $978 million increase
Net earnings = $1,378 million - $921 million
= $457 million increase
Hence, Calculate the percentage change by dividing the dollar change by the previous year's figure and multiplying by 100 as;
Net sales = ($5,105 million / $35,475 million) x 100
= 14.4% increase
Earnings before taxes = ($978 million / $1,313 million) x 100
= 74.4% increase
Net earnings = ($457 million / $921 million) x 100
= 49.6% increase
And, Vertical Analysis:
Calculate the percentage of each item in relation to the net sales by dividing each item by the net sales and multiplying by 100:
Net sales = $40,580 million / $40,580 million x 100
= 100%
Earnings before taxes = $2,291 million / $40,580 million x 100
= 5.6%
Net earnings = $1,378 million / $40,580 million x 100
= 3.4%
Thus, Value of Horizontal Analysis:
⇒ Net sales = 14.4%
⇒ Earnings before taxes = 74.4%
⇒ Net earnings = 49.6%
Value of Vertical Analysis;
⇒ Net sales = 100%
⇒ Earnings before taxes = 5.6%
⇒ Net earnings = 3.4%
