6x-4y=18
-x-6y=7 multiply this equation by 6 both sides
6x-4y=18
-6x-36y=42 add both equations
-4y-36y=18+42 combine like terms
-40y=60 so y = -4/6= -2/3
subtitute y=-2/3 in -x-6y=7
-x-6*(-2)/3=7 solve
-x+4=7 subtract 4 from both sides
-x=7-4
x= -3
8.
substitute y=4x+5 in to the second equation
12x-3(4x+5)=9
12x-12x-15=9
-15=9 is never true so the equation has no solutions

Answers
PART A:
Finding the slope of the function f(x)
Choose any two pairs of coordinate from the table; (-1, -15) and (0, -10)
Let (-1, -15) be (x₁, y₁) and (0, -10) be (x₂, y₂)
Slope =
Slope of f(x) = 5
The function g(x) is given in the straight line equation form
Where, is the slope and is the y-intercept
Slope of g(x) = 2
-----------------------------------------------------------------------------------------------------------
g(x) = 2x + 8
Where, the slope (m) = 2 and the y-intercept (c) = 8
The y-intercept of g(x) is 8
for f(x), we can read the y-intercept when x = 0.
From the table, when x = 0, y = -10
The y-intercept of f(x) is -10
Function g(x) has higher y-intercept

Find the principal. Annual rate of interest = 11 \%=11%equals, 11, percent Period = 3=3equals, 3 years Total interest = 825=825equals, 825 rupees Principal ==equals rupees
Answers
Answer:
Principal = 2,500 rupees
Step-by-step explanation:
The interest or simple interest is the extra money gained on n invested amount of money yielding a certain percentage interest at a time (t) in years
The formula for simple interest is given as follows:
I = P × R × T
where:
I = interest = 825 rupees
P = principal
R = interest rate = 11% = 11/100 = 0.11
T = time = 3 years
∴ 825 = P × 0.11 × 3
825 = P × 0.33
P = 825 ÷ 0.33
P = 2,500 rupees
This means that 2,500 rupees was invested to saved to yield an interest of 825 rupees after 3 years at a rate of 11% per year

Christopher is deciding between two landscaping companies for his place of business.

$50 per hour and a $100 equipment fee. Let A represent the amount Company A
would charge for t hours of landscaping, and let B represent the amount Company B
would charge for t hours of landscaping. Write an equation for each situation, in
terms of t, and determine the number hours, t, that would make the cost of each
company the same.
A=
B=
Answer:
Answers
Answer:
A=30t+200
B=50t+100
The number of hours,t, that would make the cost of each company the same is 5.
30(5)+200= A
150+200=350
50(5)+100= B
250+100=350
Step-by-step explanation:
The time required in hours for the cost for both the companies to be the same is 5 hours.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
From the given information the total cost C in terms of t for company A is,
C = 30t + 200 and for company B is, C = 50t + 100.
Therefore, the number of hours when the cost of each company would be the same is,
30t + 200 = 50t + 100.
30t - 50t = 100 - 200.
- 20t = - 100.
20t = 100.
t = 10/2.
t = 5 hours.

You are riding a roller coaster when a shoe falls off your foot. The function y=300−16t2 represents the height y (in feet) of the shoe t seconds after it falls off your foot. The shoe lands on the top of an 11-foot-tall building. After how many seconds does the shoe hit the building?
Answers
Answer:
Time to land on 11ft is 4.25 seconds
Step-by-step explanation:
Given
[tex]y = 300 - 16t^2[/tex]
Required
Solve for t when height is 11ft
This implies that [tex]y = 11[/tex]
So: substitute 11 for y in [tex]y = 300 - 16t^2[/tex]
[tex]11 = 300 - 16t^2[/tex]
Collect Like Terms
[tex]16t^2 = 300 - 11[/tex]
[tex]16t^2 = 289[/tex]
Express both sides as squares
[tex]4^2 * t^2 = 17^2[/tex]
[tex](4t)^2 = 17^2[/tex]
Take square roots of both sides (ignore negative)
[tex]4t = 17[/tex]
Solve for t
[tex]t = \frac{17}{4}[/tex]
[tex]t = 4.25[/tex]
Hence, time to land on 11ft is 4.25 seconds

Answers
Answer:
On melissa's 6th birthday, she gets a $4000 cd that earns 3% interest, compounded quarterly. If... | like | dislike ... The amount accumulated in a certificate of deposit (CD) is found using the compound interest formula as a CD also earns compounding interest. ... The number of years between the 6th and 12th birthdays is 6
Step-by-step explanation:
There will be $41142.87 available on Melissa's 16th birthday.
What is compound interest?Interest accrued on both the principal sum of money and the interest already earned.
The formula for compound interest is p(1+r/100)ⁿ - p
Where p is principal, r is rate and n is time.
Given that,
Amount that Melissa gets on her 6th birthday = $4000
Rate of interest = 6% compounded quarterly.
Melissa gets amount on her 16th birthday, time = 6 years
The amount that Melissa will get on her 16th birthday
= 4000(1+6/100)¹⁰ˣ⁴
= 4000 (106/100)⁴⁰
= 4000 x 10.2857
= 41142.87
Melissa will get $41142.87 on her 16th birthday.

1. A local pizzeria sold 65 pizzas yesterday.
(step 1) The owner offers the employees a bonus if the number of pizzas sold increases by 20% today. How many pizzas must the pizzeria sell for employees to receive the bonus? Explain your reasoning.
(Part 2) Suppose the actual number of pizzas sold today was 60. Describe the number of pizzas sold as a percent increase or decrease, rounded to the nearest hundredth. Show your work.
Answer:
Answers
Part 1
Pizzas sold last day = 65
Increasement needed in sale = 20%
pIzzas to be sold today
= 65 + 20% of 65
= 65 + 20/100 × 65
= 65 + 1/5 × 65
= 65 + 1/1 × 13
= 65 + 13
= 78
Part 2
Pizzas sold last day = 65
Pizzas sold today = 60
60 = 65 + x% of 65
60 = 65 + x/100 × 65
60 - 65 = x/20 × 13
- 5 = x/20 × 13
-5/13 = x/20
-5/13 × 20 = x
-7.692 = x
Therefore, there was a decrease in pizza sale by 7.692%
By rounding off,
The decrease in pizza sale was by 7.700%.
= 7.7%
