Pictures attached-- 100 points!! Assuming that any increase occurs in whole dollar amounts, what is the maximum possible increase that maintains the desired minimum revenue? Explain why this is true.
Answer:
Part A:
Cost: 10+x
Customers: 16 - 2x
Part B:
-2x^2+-4x+160 ≥ 130.
Part C:
$12
Part D:
$12 because it is greater.
Step-by-step explanation:
To know how to solve you do this
Put each number from part c like 13 is 3 and change the x
for example
-2(x)^2-4(x)+160
to
-2(3)^2-4(3)+160
Is it greater than ≥ 130 or equal to?
What evera is greater to is the answer.

Show that 1 + tan2(x) = sec2(x)
Answer:
tan2(x) + 1 = sin2(x)/cos2(x) + 1 = [sin2(x) + cos2(x)]/cos2(x) = 1/cos2(x) = (1/cos(x))2 = sec2(x). Thus tan2(x) + 1 = sec2(x).

Natalie invests $5,632 in a retirement account with a fixed annual interest rate of 2% compounded 12 times per year. What will the account balance be after 16 years?
A) $8,398.46
C) $7,753.92
B) $8,610.85
D) $7,910.43
Answer:
C) $7,753.92
Step-by-step explanation:
Given data
Principal= $5,632
Rate=2%
n= 12
Time = 16 years
The expression for compound interest is
A=P(1+r/n)^nt
substitute
A= 5632(1+0.02/12)^12*16
A=5632(1+0.02/12)^12*16
A= 5632(1+0.00166)^12*16
A= 5632(1.00166)^12*16
A= 5632(1.00166)^192
A=5632*1.375
A=$7744
Hence the approximate amount is C) $7,753.92

is 5 a solution to 7x-4+x=12? Explain
Answer:
No, 5 isn't a solution to 7x - 4 + x = 12
Step-by-step explanation:
7x - 4 + x = 12
combine common x-values
8x - 4 = 12
add
8x = 16
solve for x
x = 2
Answer:
No, 5 is not the solution...
Step-by-step explanation:
7x-4+x=12
7x+x=12+4
8x=16
x=16/8
x=2 is the solution

Vocab: Altitude
means the height of an object or point in relation to sea level or ground level.
Answer:
1986-2510=-524
-524-420=-994

I just need to drag the degrees to their corresponding parts attached (Angles in Circles) please help I don’t which ones would be correct
9514 1404 393
Answer:
DF = 75°FBE = 105°FC = 60°CBE = 45°DAC = 225°ABE = 135°AFE = 225°ABF = 120°Step-by-step explanation:
AC and DE are diameters, so divide the circle into equal portions that have a total angle measure of 180°.
angle ABD = 180° -angle DBF - angle FBC = 180° -75° -60°
angle ABD = 45°
angle CBE is a vertical angle to angle ABD, so has the same measure, 45°.
angle ABE is supplementary to angle CBE, so has measure 180° -45° = 135°. Long arc AE is 360° less this value, so is 360° -135° = 225°. Vertical angle DBC has the same measure as angle ABE, so long arc DAE will also be 225°.
angles FBC and CDE add to make angle FBE, so that angle is ...
angle FBE = 60° +45° = 105°
7. The price of a bike at Store A is 5/6 the price at store B. The price at store A is $150.60. Write and solve an equation to find out how much the bike is at store B. How much did you save by buying the bike at Store A.
As a little tip that's helped me personally when I was taking algebra, making equations for word problems feels a lot easier when you "translate" equations you make into words to make sure that you're using the right equation.
Let's boil down what the question tells us. 5/6 of the price tag of a bike from Store B is the price of a bike from Store A, which is $150.60. Let's use the variable 'b' to represent the price of Store B's bike.
[tex]\frac{5}{6}[/tex] * b = 150.60
Try "translating" the equation above. "5/6 of the price of a Store B bike is equal to 150.60." That seems about right, doesn't it? Let's isolate 'b' so we can get an official answer.
Multiply both sides by 6 to get rid of the denominator:
[tex]\frac{5b}{6}[/tex] * 6 = 150.60 * 6
5b = 903.6
Divide both sides by 5 to get rid of b's coefficient:
[tex]\frac{5b}{5}[/tex] = [tex]\frac{903.6}{5}[/tex]
b = 180.72
The price of a bike from Store B is $180.72

How do you know which number is the largest when you compare integers?
Answer:
Step-by-step explanation:
Lets take 4905 and 802
Firstly to figure out which of these two numbers is bigger we first look at the highest place value that either one of these two numbers have
In this case its 4 in the thousands place in the number 4905
Next we look at which number 802 has in the thousands place
In this case there is no number or 0
4 is bigger than 0 so we know that 4905 is bigger than 802
Lets take another example
4905 and 8204
Here both numbers have a number in the thousands place on is 8 and the other is 4
8 is bigger than 4 so 8204 must be larger
I'm just saying comparing integers should come very easily and you really don't need to think much to figure this out
I'm guessing you mean how do you compare numbers which are non-integers like 4/6 or 4/5 and this is quite easy
There are multiple ways but one method is to just multiply the denominator of one fraction with the numerator of the other and do the same for the other fraction
lets take 4/6 and 4/5
4*5=20
and 4*6= 24
4/6 we can assign 20
and 4/5 is 24
the bigger number is 24 so 4/5 is bigger

Question 9 (1 point)
In the middle school PTA there is a total of 47 men and women. The number of women the PTA is 2 more than four times the number of men. How many women are in the
PTA?
Let the number of men = x
Let the number of women = y
x + y = 47
y = 2 + 4x
We substitute
x + 2 + 4x = 47
Collect like terms
5x = 47 - 2
5x = 45
x = 45/5 = 9
y = 2 + 4x
y = 2 + 4 × 9
y = 2 + 36
y = 38
Therefore, the number of women = y = 38 women

So if we are counting in 100's then the decimal point stays where
it is and we move the number of 3.5 to the left until the
3 becomes hundreds.
Note that we have to insert a place holder of 0 just to the left of the decimal point to make sure the three is viewed as in the hundreds.
