The answer is below
Step-by-step explanation:
Breakeven point is the point of balance where their is neither a loss or a profit. At the breakeven point, the revenue gotten from the sell of goods is equal to the cost of production of the goods, hence the profit is zero.
Given the profit function:
P=-2b² + 14b - 20
At breakeven P = 0, hence:
0 = -2b² + 14b - 20
-2b² + 14b - 20 = 0
-2b² + 10b + 4b - 20 = 0
-2b (b - 5) + 4(b - 5) = 0
(b - 5)(-2b + 4) = 0
b - 5 = 0; or -2b + 4 = 0
b = 5; or b = 2
Since b is in thousands, hence the company breaks even when the number of skateboards produced is either 2000 or 5000

If y varies directly with x and y=95 when x=5, find x when y=38.
Answer:
X is 2
Step-by-step explanation:
the equation is Y = 19X
when X=5, Y=95
when Y=38, X = 38/19 = 2

You choose a marble at random from a bag containing 12 red, 12 blue, 4 green, 6 yellow, and 26 black
marbles,
The marble is red
Answer:
12+12+4+6+26=50
12/50=6/25=0.24=24%
Answer:
1/5.
Step-by-step explanation:
First you have to add up all of the numbers: 12+12+4+6+26. Then you have to find how many red marbles there are, which this case there are 12, so you get your fraction of 12/60 which can be reduced to 1/5.

April measured her bed and made a scale drawing. The scale of the drawing was 1
centimeter = 6 inches. In the drawing, the bed is 10 centimeters long. What is the
length of the actual bed?
Answer:
60 inches
Step-by-step explanation:
Given data
We have the scale of the drawing as
1cm= 6 inches
Now if 1 cm is equivalent to 6inches
then 10cm will be x inches
Cross multiply we have
x*1= 10*6
x= 60 inches
Hence the length of the actual bed is 60inches

Someone help- I don't know how to solve this- maybe my teacher typed it in wrong? 2.4(m - 3) = 3.8 = -8.2
Answer:
m = 4.58
Step-by-step explanation:
Given equation :
2.4 ( m - 3) = 3.8
So now we open the brackets and multiply the terms.
⇒ 2.4 m - 7.2 = 3.8
⇒ 2.4 m = 3.8 + 7.2
⇒ 2.4 m = 11
⇒ m = [tex]\frac{11}{2.4}[/tex]
⇒ m = 4.58
Therefore, the correct value of the variable m by solving the equation is 4.58

Find m
A.)38
B.)22
C.)52
D.)12
Answer:
x =12
Step-by-step explanation:
The two angles add to 90 degrees
4x+4 + 5x-22 = 90
Combine like terms
9x - 18 = 90
Add 18 to each side
9x -18+18 = 90+18
9x = 108
Divide each side by 9
9x/9 = 108/9
x =12
Answer:
C.) 52°
Step-by-step explanation:
find x first
4x + 4 + 5x - 22 = 90
9x - 18 = 90
9x = 108
x = 12
plug it into the expression
4(12) + 4
= 48 + 4
= 52°

Can someone please help me this?
Answer:
Yes
Step-by-step explanation:
We can make one equation other to the other to solve for x-value first;
=> -4x = x - 5
=> -4x + (-x) = -5
=> -5x = -5
=> x = -5/-5
=> x = 1
Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;
=> y = x - 5
=> y = (1) - 5
=> y = -4
Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.

9514 1404 393
Answer:
(3)(1)0x -1y = -9Step-by-step explanation:
The general approach here is to choose a variable you want to eliminate, identify the coefficients of it, and use those to multiply the equations so adding the products will eliminate the variable.
Here, the coefficients of x are -1 and -3; the coefficients of y are 2 and 5. We often like to choose the set of coefficients that includes 1 or where the coefficients are related by an integer factor. These criteria suggest that we should use the coefficients -1 and -3. One of our multipliers must be the opposite of one of these coefficients. So, we choose for them to be -3 and +1.
That is, multiplying the first equation by -3 will make the x-coefficient be 3; multiplying the second equation by 1 will make the x-coefficient be -3. Adding these equations will then eliminate x terms.
(-3)(-x +2y = 12)
+ (1)(-3x +5y =27)
gives (3x -6y) +(-3x +5y) = -36 +27
which simplifies to the sum ...
0x -1y = -9
__
Dividing by the coefficient of y, we find y = 9. Substituting into the first equation, we have ...
-x +2(9) = 12)
x = 18-12 = 6
The solution is (x, y) = (6, 9).

Let d(t) be the total number of miles Joanna has cycled, and let t represent the number of hours after stopping for a break during her ride. So, d(4) = . This means that after , Joanna .
Answer:
68
Step-by-step explanation:
Total mile cycled, d(t) ;
d(t) = 12t + 20
At d(4)
t = 4 ;
We have;
d(4) = 12(4) + 20
d(4) = 48 + 20
d(4) = 68
After, 4 hours of cycling, Joanna cycled a total distance of 68 miles

if f(x) = -4x+3 and g(x) = 3 +2x-4 find (f+g) (x)
Answer:
Please be careful with your typing [f(x)=-sqrt(x)+6 ... right? g(x)=-4*sqrt(x)-3 ... or -4*sqrt(x)+3 ... one or the other, right?
If so, you are dilating by a factor of 4, -1 versus -4 as multiplier of sqrt(x); and, translating up 3 units (6 versus 3) or 9 units (6 versus -3).
Step-by-step explanation:
Answer:
-2x+2
Step-by-step explanation:
f(x) = -4x+3 and g(x) = 3 +2x-4
Note what you put for g(x) simplifies to 2x-1
(f+g) (x) = -4x+3+ 3 +2x-4
Combine like terms

Ac=14 bc=11 what is the radius
Answer:
Radius = √75 or 5√3 or 8.7
Step-by-step explanation:
This forms a right triangle meaning you can use Pythagorean Theorem to solve for the missing side which, in this case, will equal the radius.
Let a = radius
a² + b² = c²
a² + 11² = 14²
a² + 121 = 196
a² = 75
a = √75 = 5√3 ≈ 8.7
Answer:
radius = ab = √75
Step-by-step explanation:
Triangle ABC is a right triangle so to find the radius, aka one of the sides of the triangle, we need to use the Pythagorean theorem.
ac^2 = bc^2 + ab^2 Pythagoras Theorem
14^2 = 11^2 + ab^2 Substitution
196 = 121 + ab^2 Alg
75 = ab^2 Alg
ab = √75 Alg = radius

Problem 3
Answer: 1/5 of a gallon per minute-------------------------
Explanation:
Two points from the graph are (10,2) and (20,4)
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (4-2)/(20-10)
m = 2/10
m = 1/5
The slope of the graph is 1/5.
Do the same for two points from the table. I'll use the first two rows
m = (y2-y1)/(x2-x1)
m = (4-2)/(10-5)
m = 2/5
The slope of the table is 2/5.
Subtract the two slopes to wrap things up:
2/5 - 1/5 = (2-1)/5 = 1/5
=====================================================
Problem 5
Answer: 23 degrees------------------------
Explanation:
Angles 1 and 3 are same side exterior angles, so they are supplementary due to the parallel lines set up here.
(angle1)+(angle3) = 180
(157) + (angle3) = 180
angle3 = 180-157
angle3 = 23 degrees
Determine whether the lines given by the fallowing equations intersect at (-1/4,3/4) show all work. 4x+8y=5, x-3y= -3
Answer:
(0, 1)
Step-by-step explanation:
First, we need to make y the subject of the formula from both expressions
For 4x+8y=5
8y = 5- 4x
y = (5-4x)/5
Similarly for x-3y= -3
-3y = -3 - x
3y = x+3
y = (x+3)/3
Since both lines intersects, hence;
(5-4x)/5 = (x+3)/3
Cross multiply
5(x+3) = 3(5-4x)
5x + 15 = 15 - 12x
5x + 12x = 15 - 15
17x = 0
x = 0/17
x = 0
Sustitute x = 0 into any of the equations
Given that y = x+3/3
y = 0+3/3
y = 3/3
y = 1
This shows that the lines intesects at (0, 1)
