Answer:
Linear Function
Step-by-step explanation:
Given
The table showing values of x and y
Required
Determine the type of function
To determine the type of function, the table represents;
One will need to determine the table equation.
Start by solving for the slope;
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
When x - 0; y = 0 and When x = 80; y = 60.
This gives
[tex]m = \frac{0 - 60}{0 - 80}[/tex]
[tex]m = \frac{- 60}{- 80}[/tex]
[tex]m = \frac{3}{4}[/tex]
The formula is determine as follows;
[tex]y - y_1 = m(x - x_1)[/tex]
When x - 0; y = 0; m = 3/4; This gives
[tex]y - 0 = \frac{3}{4}(x - 0)[/tex]
[tex]y = \frac{3}{4}(x - 0)[/tex]
Open Bracket
[tex]y = \frac{3}{4}x - 0[/tex]
[tex]y = \frac{3}{4}x[/tex]
The above is an example of a linear equation.
Hence; option B answers the question
In another baseball division, one team had a winning percentage of 0.444 repeating What fraction of their games did this team win? Let x=0.4 repeating
Answer:
[tex]x = \frac{4}{9}[/tex]
Step-by-step explanation:
Given
Winning Percentage = 0.444 repeating
Required
Represent as a fraction
Represent the percentage with x
[tex]x = 0.444[/tex]
Convert to fraction

Rebecca Wilson was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 846 points. The number of two-point field goals that Rebecca made was 77 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 30 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Rebecca Wilson made during the 2006 regular season.
Answer:
Number of two point goals = 169
Number of three point goals = 123
Number of free throws = 139
Step-by-step explanation:
Let the number of two point goals = [tex]x[/tex]
Let the number of three point goals = [tex]y[/tex]
Let the number of free throws = [tex]z[/tex]
As per the given statements:
[tex]x = 2y-77 ...... (1)[/tex]
[tex]z = x-30 ...... (2)[/tex]
Using equation (1):
[tex]z = 2y-107[/tex] ...... (3)
Total number of points from two point goals = [tex]2x[/tex]
Total number of points from three point goals = [tex]3y[/tex]
Total number of points from free throws = [tex]z[/tex]
[tex]2x+3y+z=846[/tex]
using (1) and (3):
[tex]2(2y-77)+3y+2y-107=846\\\Rightarrow 4y-154+5y-107=846\\\Rightarrow 9y-261=846\\\Rightarrow 9y=846+261\\\Rightarrow 9y=1107\\\Rightarrow y =123[/tex]
By (1):
[tex]x = 2\times 123-77 =169[/tex]
By (3):
[tex]z =2\times 123-107 = 139[/tex]
So, answers are:
Number of two point goals = 169
Number of three point goals = 123
Number of free throws = 139

Will give brainliest -2u+6w=9 rearrange the equation so w is an independent variable. PLEASE HELP!
Answer:
[tex]\Large \boxed{w=\frac{2u+9}{6} }[/tex]
Step-by-step explanation:
[tex]-2u+6w=9[/tex]
Adding 2u to both sides.
[tex]6w=9+2u[/tex]
Dividing both sides by 6.
[tex]\displaystyle w=\frac{2u+9}{6}[/tex]
Answer:
So we have this equation:
[tex]-2u + 6w = 9[/tex]
And we need to rearrange it to make the w an independent variable.
That means we need to solve the equation for w:
[tex]-2u + 6w = 9[/tex]
First thing we need to do is passing the [tex]-2u[/tex] to the right summing:
[tex]6w = 9 + 2u[/tex]
Next, we can pass the 6 (which is multiplying the w) to the right dividing:
[tex]w = \frac{9+2u}{6}[/tex]
we can also write it as this:
[tex]w = \frac{9}{6}+\frac{2u}{6}=\frac{3}{2}+\frac{u}{3}[/tex]
If BD BC, BD = 5x – 26, BC = 2x + 1, and AC = 43, find AB.
Answer:
AB = 24
Step-by-step explanation:
BD = 5x – 26
BC = 2x + 1
AC = 43
Using the segment addition postulate, AC = AB + BC.
We know that BD = BC, BD = 5x-26 and BC = 2x+1. We can set up an equation to find the value of x:
5x - 26 = 2x + 1 Subtract 2x from each side
5x - 26 - 2x = 2x + 1 - 2x
3x-26 = 1 Add 26 to each side
3x-26+26 = 1+26
3x=27 Divide both sides by 3
3x/3 = 27/3
x = 9
This means that BC = 2x + 1 = 2(9) + 1 = 18 + 1 = 19.
We know that AC = AB + BC; using our given information as well as the value of BC we just found, we have
43 = AB + 19 Subtract 19 from each side
43 - 19 = AB + 19 - 19
24 = AB

Domain: [tex]-4 < x \le 4[/tex]
Range: [tex]-2 \le y < 5[/tex]
=======================================
Explanation:
The domain is the set of allowed x values.
The left-most point on this graph is at (-4,5). This means x > -4 or -4 < x. The open hole indicates we don't include x = -4 as part of the domain.
The right most point is at (4,-2). So [tex]x \le 4[/tex]
Combine [tex]-4 < x[/tex] and [tex]x \le 4[/tex] together to get the domain [tex]-4 < x \le 4[/tex]
----------------------
The range is the set of possible y values.
The range spans from -2 to 5, including -2 but excluding 5. This is because the smallest y value possible is y = -2, and the upper bound for the y values is y < 5 due to the open hole.
Therefore the range is the compound inequality [tex]-2 \le y < 5[/tex]
Answer: domain - -4
Range- -2

Complete question is;
The function f(x) = (25000 + 280x)/x models the average cost per unit, f(x), for Electrostuff to manufacture x units of Electrogadget IV. How many units must the company produce to have an average cost per unit of $390?
Answer:
227 units
Step-by-step explanation:
We are given the function;
f(x) = (25000 + 280x)/x
Where;
f(x) is the average cost per unit
x is the number of units
Now, we want to find out how many units the company must produce to have an average cost per unit of $390.
Thus, plugging $390 for f(x), we have;
390 = (25000 + 280x)/x
When we cross multiply, we get;
390x = 25000 + 280x
390x - 280x = 25000
110x = 25000
x = 25000/110
x ≈ 227

Convert 0.83 into a fraction.
0.83 * 100 = 83, so 0.83 = 83/100.
But in case you meant the slightly more interesting repeating decimal, 0.8333...:
Let x denote this number. Then
10x = 8.333...
100x = 83.333...
==> 100x - 10x = 83.333... - 8.333...
==> 90x = 83 - 8 = 75
==> x = 75/90 = 5/6
From the observation deck of the lighthouse at Sasquatch Point 55 feet above the surface of Lake Ippizuti, a lifeguard spots a boat out on the lake sailing directly toward the light
house. The first sighting had a angle of depression of 8.1 and the second sighting had an angle of depression of 25.7°. How far had the boat traveled between the sightings?
Answer:
272.17 ft
Step-by-step explanation:
Since the angle of depression of the sighting equals the angle of elevation of the lighthouse from the boat, using trigonometric ratios,
tanθ = x/d where θ = angle of sighting, x = height of lighthouse =55 ft and d = distance of boat from lighthouse at sighting
So, d = x/tanθ
when θ = 8.1°, for the first sighting,
d₁ = 55/tan8.1 = 386.45 ft
when θ = 25.7°, for the second sighting,
d₂ = 55/tan8.1 = 114.28 ft
The distance the boat traveled between the two sightings is thus d₁ - d₂ = 386.45 ft - 114.28 ft = 272.17 ft

In 2010 Sacramento received 23 inches in annual precipitation , in 2011 the city received 17 inches in anual percpation , in which year was there more precpition?
Answer:
There was more precipitation in the year 2010.
Step-by-step explanation:
Here in this question, we have the data for the amount of precipitation received in two different years in a city called Sacramento.
Now, we are tasked with finding in which of the two years was there more precipitation.
From the question, we can identify the following;
in 2010, precipitation was 23 inches
in 2011, precipitation was 17 inches
We can see that 23 inches is greater than 17 inches. So what this mean is that the precipitation in 2010 was more than the precipitation received in 2011.
