How many solutions can be found for the equation 12x + 8 = 10x + 18? (4 points)
a
No Solution
b
One
c
Two
d
Infinitely Many
Answer:
b
Step-by-step explanation:
Given
12x+ 8 = 10x + 18 ( subtract 10x from both sides )
2x + 8 = 18 ( subtract 8 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
The equation has one solution
Answer:
B
Step-by-step explanation:
verification
12 x 5 + 8 = 10 x 5 + 18

The first year of a charity walk event had an attendance of 500. The attendance
y increases by 5% each year.
How many people will attend in the 10th year?
A) 525 People
B) 814 People
C) 250 People
Answer:
b
Step-by-step explanation:
Number of people in the 10th year can be determined using this formula
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future number of people at the charity
P = number of people at the charity in the first year
R = rate of increase
N = number of years
500 x (1.05)^10 = 814 people
you put 5,000 dollers in an account that earns 4% intrest compounded annually . how much intrest will you have earned in 10 years?
Answer:
$2401.22
Step-by-step explanation:
Since 4% of 5000 is 200, we add 200 to our total, after 9 more 4% interest calculations, all we need to do is subtract the total by 5000.

Find the simple interest. Round to the nearest
cent if necessary.
$1450, 32%, 3 months
Answer: $116
Step-by-step explanation:
Simple interest is calculated using the formula = PRT
where,
P = principal = $1450
R = rate = 32%
T = time = 3 months = 3/12 = 1/4 = 0.25
Interest = PRT
= 1450 × 32% × 0.25
= 1450 × 0.32 × 0.25
= $116
The simple interest is $116

Mark and Tony have a total of 121 baseball cards. Tony has 5 more than three times Mark's amount. How many cards does Mark have?
Answer:
29
Step-by-step explanation:
make Mark x and Tony 3x + 5
X+3x+5=121
The number of baseball cards in between Tony and Mark is a linear equation, where Mark has 29 cards.
What is a linear equation?A linear equation is an equation where the variable has the highest power of one. A linear equation may be consists of multiple variables.
Let, Mark has x cards.
Therefore, Tony has (3 × x + 5) cards = (3x + 5) cards.
Given, x+ 3x + 5 = 121
⇒ 4x +5 = 121
⇒ 4x = 121 - 5
⇒ 4x = 116
⇒ x = 116 / 4
⇒ x = 29
Hence, Mark has 29 cards.

4x+5y=60. what is the x and y intercepts? show work pls!!
Answer: (4,5)
Because I don't know another way I can solve
Step-by-step explanation:
Answer:
x-intercept: (15, 0)
y-intercept: (0, 12)
Step-by-step explanation:
1.) convert the equation to y=mx+b format
4x + 5y= 60
5y = -4x + 60
y = -4/5x + 12
2.) Now we know that "b" in the equation is the y-intercept. 12 is b so the y-intercept is 12.
3.) To find x intercept we will plug in y=0.
0 = -4/5x + 12
-12 = -4/5x
15 = x

a company makes $10 000 in 2017. The projection of profit increase is fixed 40% from the previous year. Predict the company profit in 2019.
Answer:
19600
Step-by-step explanation:
For every year the profit increases by 40% so to figure out the profit from 2017 to 2018 you do 10,000*1.4 to and get 14,000. To get 2019's profit you do the same process, but use 2018's profit of 14,000 instead of 2017's profit to get 19,600.

Solve the following system of equations by elimination: 2x + y = -1 3x - y = -9
Answer:
x = -2, y = 3
Step-by-step explanation:
2x + y = -1
3x - y = -9
2x + y + 3x - y = -1-9
5x = -10
x = -2
2(-2) + y =-1
-4 + y = -1
y = 3

A process is stationary if: a. any collection of random variables in a sequence is taken and shifted ahead by h time periods, the joint probability distribution remains unchanged. b. there is serial correlation between the error terms of successive time periods and the explanatory variables and the error terms have positive covariance. c. there is no serial correlation between the error terms of successive time periods and the explanatory variables and the error terms have positive covariance. d. any collection of random variables in a sequence is taken and shifted ahead by h time periods; the joint probability distribution changes.
Answer:
B.any collection of random variables in a sequence is taken and shifted ahead by htime periods, the joint probability distribution remains unchanged
Step-by-step explanation:
In most of the time series techniques , there is usually a common assumption that data are stationary. A stationary process can be regarded as one that has properties such as variance mean, variance as well as autocorrelation structure not changed over time. The properties is independent as regards the time the series is observed.
✓ Time series that has trends or seasonality cannot be regarded as stationary, because the value of the time series which exist in different times will be affected by the trend and seasonality.
✓A white noise series can be regarded as stationary because the time you observe it does not matter, it will always look much the same at all point in time.
✓ It should be noted that process is stationary if any collection of random variables in a sequence is taken and shifted ahead by htime periods, the joint probability distribution remains unchanged

Calculate the distance between Points A and B.
A.4.5
B.7.1
C.7.8
D.9.2
Answer:
7.8 units separate the points A and B.
Step-by-step explanation:
Going from B to A, x increases by 6 (this is the horizontal side of the triangle formed by vertices A and B), and y increases by 5. Applying the Pythagorean Theorem, we get
d = √(6² + 5²), or √(61, which is approximately 7.8, the desired distance.
