Step-by-step explanation:
substitute a point value into the equation to find the missing number (the y-intercept)
you could either substitute (0,-4) or (1,2) into the equationn
y = 6x + b
-4 = 6(0) +b
-4 = 0+b
b = -4
or
y = 6x +b
2 = 6(1) + b
2= 6 +b
b= -4
Answer:
-4
Step-by-step explanation:
Y = mx+b is the slope intercept form of the equation
where m is the slope and b is the y intercept
The y intercept is where the line crosses the y axis
It is the value where x is zero
(0,-4) the x value is zero so the y intercept is -4

Step-by-step explanation:
A plumber charges $130 2 hours of work and $235 for 5 hours of workWhat is the of change in dollars per hour
Answer:
235
Step-by-step explanation:
Figure the rates per hr.
110/3 = 36 2/3
160/5 = 32.
So, the rates are not the same.
Knowing a bit about plumbers, they normally charge a basic fee to just show up, and then they charge per hr.
In cases like these, where we're asked to project to a new data point (in this case an 8-hr job), you should immediately think of a graph. The x-axis would be the hours worked. The y-axis would be the charge for the work (the cost of the job).
We're given two pairs of values:
(3,110) and (5,160).
The next step is to fit a line to them.
y = mx+b is the general equation for a line.
m = the slope = rise/run = change in y / change in x
Call the change in y, dy (for delta y).
Call the change in x, dx (for delta x).
m = dy/dx = 50/2 = 25
The slope is thus 25, which means for each hour, the price goes up by $25. That means the plumber charges $25/hr.
We also know the plumber charges $110 for a 3-hr job. 3*25 = $75. So the base charge would be $110-75 = $35.
y = 25x + 35
Checking this formula at x=3, we know it is 110.
Checking it at x=5, we obtain:
y = 25*5 + 35 = 125 + 35 = 160.
That checks.
Now to figure an 8-hr job, set x=8 and use the equation"
y = 25*8 + 35.
y = 200 + 35.
y = 235.
That means an 8-hr job costs $235.

x?y2
(-2y+5x) (3x-2y)
(-2y+5x) (3x-2y)
x?y?
Answer:
Step-by-step explanation:
Answer:
(-2y+5x) / (3x - 2y)
Step-by-step explanation:
If we write this sentence, we have:
((-2/x) + (5/y)) / ((3/y) - (2/x))
If we do LCM in the denominators of each fraction, we have:
((-2y+5x)/xy) / ((3x - 2y)/xy)
We can cut the 'xy' in the numerator and denominator of the whole fraction:
(-2y+5x) / (3x - 2y)
The final expression we have is (-2y+5x) / (3x - 2y)

Drag the orange point on the cube to change its side length. Then set the base of the pyramid to the same dimensions as a face on the cube. Also set the height of the pyramid to the same side length as the cube. Note the volumes of the cube and the pyramid. Record the volumes for a few sets of heights and bases, and then calculate the ratio of the volumes. Be sure the dimensions for the cube and the pyramid are the same in each set. (You might see some discrepancies in the tool due to rounding of decimals.) Round your calculations for the ratio to the hundredths place. The first one has been done for you.

Step-by-step explanation:
An artist can sell 20 copies of a painting at $100 each, but for each additional copy he makes, the value of each painting will go down by a dollar. Thus, if 22 copies are made, each will sell for $98. How many copies should he make to maximize his sales?
Answer:
40 more paintings in order to maximize sales making a total of 60 paintings
Step-by-step explanation:
Let x= no.of copies above 20
Total Sales(x) = (number of copies)(price per copy)
Sales (x)= (20 +x)(100 –x)
Open bracket
=1200-20x+100x-x^2
=1200+80x-x^2
Derivative of the sales
80-2x=0
80=2x
Divide both sides by 2
40=x
Because Sales(x)= –2, this is maximal by the second derivative test
The artist should make 40 more paintings in order to maximize sales making a total of 60 paintings.
The artist 60 copies should he make to maximize his sales
The artist can sell 20 copies at $100 each.
So, the total sales is:
Total =(20) * (100)
For each additional copy he makes, the value of each painting reduce by a dollar.
So, the total sales becomes
Total = (20 + x) * (100 - x)
Rewrite as:
[tex]y = (20 + x) * (100 - x)[/tex]
Expand
[tex]y = 2000 - 20x + 100x - x^2[/tex]
Evaluate the like terms
[tex]y = 2000 +80x - x^2[/tex]
Differentiate
[tex]y' = 80 - 2x[/tex]
Set to 0
[tex]80 - 2x = 0[/tex]
Collect like terms
[tex]- 2x = -80[/tex]
Divide both sides by -2
[tex]x = 40[/tex]
Recall that the initial copies is 20.
So, the new copies would be:
New = 20 + 40
New = 60
Hence, the artist 60 copies should he make to maximize his sales

A man is able to run an arc of 150° along a circular track, whose radius is 150 ft. How far did the man run?
Answer:
392.5 ft
Step-by-step explanation:
First, let's find the circumference of the track. This is 2 * 3.14 * 150 = 942 ft. 150° is 5 / 12 of 360° (the full circle) so that means that the minor arc it forms (which is also the arc the man ran) is 5/12 of the circumference. This means that the answer is 5/12 * 942 = 392.5 ft. Hope this helps!
Answer:
Step-by-step explanation:
length of the arc = angle/360 * 2 * pi * r
150/360 * 2 * 22/7 * 150
393 ft

Archie plays a word board game. He places 98
lettered tiles and 2 blank tiles in a bag. Players
will draw tiles from the bag one at a time
without looking.
What is the probability that the first tile drawn
will be a blank tile? Labeled with a letter? A
vowel? A consonant?
Select each type of tile to see its probability.
Answer:
blank: 0.02
lettered: 0.98
vowel: 0.42
consonant: 0.56
Step-by-step explanation:
In the figure attached, the number of tiles of each letter are shown.
number of blank outcomes: 2
number of lettered outcomes: 98
number of vowel outcomes: 9 + 12 + 9 + 8 + 4 = 42
number of consonant outcomes: 98 - 42 = 56
Total number of outcomes: 100
Probability that first tile drawn is a blank tile: 2/100 = 0.02
Probability that first tile drawn is labeled with a letter: 98/100 = 0.98
Probability that first tile drawn is a vowel: 42/100 = 0.42
Probability that first tile drawn is a consonant: 56/100 = 0.56

Answer:
1. 8a
2. -13
Step-by-step explanation:
1. 2(5a − 4a) + 6a
= 10a - 8a + 6a
= 2a + 6a
= 8a

The sum of two numbers is 73. When the smaller number is subtracted from twice the greater number, the result is 50. Find the numbers. Please use a let statment and an algebraic solution. Thanks! :)
Answer:
The big number is 41 and the small number is 32.
Step-by-step explanation:
b + s = 73
2b - s = 50 Add these equations together
3b = 123 Divide both sides by 3
b = 41
Now plug this into the first equation to find s
41 + s = 73
-41 - 41
s = 32

To avoid a storm, a pilot of a vintage biplane flies up 2,500 feet, but stays below 32,000 feet. Write and solve an inequality to find the maximum original altitude of the plane.
a + 2,500 > 32,000; a > 34,500
a + 2,500 < 32,000; a < 29,500
a + 2,500 < 32,000; a < 34,500
a + 2,500 > 32,000; a > 29,500
Answer:
a + 2,500 < 32,000; a < 29,500
Step-by-step explanation:
This shows the 2,500 can be adapted to become less than 29,500 in additional measure when flying.
As 2,500+ 29,500 = 32,000
The a+2,500<32,000 is also correct as this shows less than and confirms that the biplane stays below 32,000.
