Answer:
-8b + 9 - 5k
Step-by-step explanation:
I am assuming the blue highlighted portion is your answer, and is not a part of the initial question
(-4b + 15 - 7k) - (6 + 4b - 2k)
Combine like terms
-4b - + 4b
Negative + Positive = Negative
-4b - 4b = -8b
15 - 6 = 9
-7k - - 2k
Negative + Negative = Positive
-7k + 2k = -5k
Put them all together:
0b + 9 - 5k
Simplify
-8b + 9 - 5k
I got the same answer as you (just in a different order)
Solve using the quadratic formula. (Identify a, b, and c. Write the
formula. Show the substitution step.
8n^2 + 4n -2 = 0
Answer:
Step-by-step explanation:
Here a = 8, b = 4 and c = -2. The discriminant here is b^2 - 4ac, which, when the above coefficients are substituted, results in:
discriminant = (4)^2 - 4(8)(-2), or 16 + 64, or 80.
The solutions are:
-(4) ± √80 -4 ± 4√5 4(-1 ±√5) -1 ± √5

Answer:
2) 2
Step-by-step explanation:
Subtract each equation from each other
x + 2y = 9
-x+ y = -3
3y = 6

what is the LCM for 9, 18 and 72
Answer:
72
Step-by-step explanation:
9 = 3^2
18 = 2 * 3^2
72 = 2^3 * 3^2
For LCM use common and not common factors with greater exponent.
Use 2^3 and 3^2.
LCM = 2^3 * 3^2 = 8 * 9 = 72
Answer: 72
Henry went to an amusement park with $100.00 and spent all of it. He spent of the money on parking. He spent $42.50 on admission to the park. He spent 20% of the money on food. He paid a $12.75 fee for admission into a water park located inside the amusement park. He spent the remainder of his money on games that cost $1.75 each. How many games did Henry play?
Answer:
19 games
Step-by-step explanation:
Henry went to an amusement park with $100.00 and spent all of it.
Starting amount = $100.00
He spent $42.50 on admission to the park.
Amount left = $100.00 - $42.50
Amount left = $57.5
He spent 20% of the money on food.
Amount spent = 20% of amount left ($57.5) = $11.5
Amount left = $57.5 - $11.5 = $46
He paid a $12.75 fee for admission into a water park located inside the amusement park.
Amount left = $46 - $12.75
Amount left = $33.25
He spent the remainder of his money on games that cost $1.75 each. How many games did Henry play?
Number of games = Amount left / Cost per game
Number of games = $33.25 / $1.75 = 19

Find the slope.
Find the y-intercept
Write the equation (y=mx+b)
At Philip’s Phones you can get a new cell phone plan for $45 a month plus $30 activation fee.
9514 1404 393
Answer:
slope: 45y-intercept: 30equation: y = 45x + 30Step-by-step explanation:
The slope is the cost per month. (A slope is often expressed as a ratio: dollars per month, in this case.) The slope is 45.
The y-intercept is the value that obtains when the number of months (in this case) is zero. It is the activation fee, 30. The y-intercept is 30.
__
The equation in slope-intercept form is ...
y = mx + b . . . . . where m is the slope and b is the y-intercept
Using the above numbers, the equation is ...
y = 45x + 30

Enter the exponential function using t (for time) as the independent variable to model the situation. Then
find the value of the function after the given amount of time.
The value of a textbook is $63 and decreases at a rate of 14% per year for 13 years.
The exponential function that models the situation is y = 63(0.86).
After 13 years, the value of the textbook is $
Answer:
An exponential function is given by;
f(x)=ba^x
where a is any value greater than 0,
b is the intial value
when a>1 then f(x) is defined as an exponential growth
when a<1 then f(x) is defined as an exponential decay
From the our function;
f(t)=15000(0.86)^t
a=0.86<1
b=15000
since a<1, the function will be an exponential decay.

An angle measures 47°. What are the measures of the angle’s complement and supplement? A. complement, 43°; supplement, 133° B. complement, 133°; supplement, 43° C. complement, 53°; supplement, 143° D. complement, 143°; supplement, 53°
Answer:
A.) complement, 43°; supplement, 133°
Step-by-step explanation:
A compliment angle is any angle(s) that adds up to 90°
A supplement angle is any angle(s) that adds up to 180°
For compliment:
90 - 47 = 43
For supplement:
180 47 = 133
Therefore, the answer would be A.

Answer:
VW = √2
Step-by-step explanation:
y = x+1
x²+y²+2x+2y+1=0 (x²+2x+1) + (y²+2y+1) = 1
(x+1)² + (y+1)² = 1 : Circle: (x-h)² + (y-k)² = r² Center (O): (h , k) = (-1 , -1) r = 1
solve for roots: x²+(x+1)²+2x+2(x+1)+1=0
2x² + 6x + 4 = 0 x²+3x+2=0
(x+1)(x+2)=0
x = -1 or x = -2
y = 0 or y = -1
V and W: (-1 , 0) and (-2 , -1) forms a 90° center angle
√vw = √1²+1² = √2
A small plant manufactures riding lawn mowers. The plant has fixed costs of GHC48,000 per day and a variable cost of GHC1,400 per unit produced. The mowers are sold for GHC1,800 each. The cost and revenue functions are in that order and , where is the total number of mowers produced and sold each day. How many units must be manufactured and sold each day for the company to break even?
Answer:
120
Step-by-step explanation:
The break-even point is the point where revenue =cost
48,000+ 1400x = 1800x
48000=400x
X=48000/400
X=120
Equilibrium quantity is 120 mowers
