What does the variable "b" stand for in exponential functions represented by the equation y = a(b)ˣ
Answer:
The rate of growth or decay
Explanation:
If b was above 1 (i.e. 1.01, 1.02) then it is an exponential growth function and if b was below 1, then it is an exponential decay function
The sum of two numbers is 11. Twice the first number minus the second number is 7
Find the numbers.
Answer:
6 and 5
Step-by-step explanation:
6 * 2 = 12
12 - 5 = 7
6 and 5 is your answer
Answer: 6; 5
Step-by-step explanation:
Based on the questions, we set up two equations, let the x be the first number, and y be the second number.
x + y = 11
2x - y= 7
x = 11 - y [Subtract y from both side]
2x - y = 7
2(11 - y) - y = 7 [Plug in 11-y for x, solve for y]
22 - 2y - y = 7
22 - 3y = 7
-3y = -15 [Subtract 22 from both side]
y = 5
x + y = 11 [Plug in 5 for y, solve for x]
x + 5 = 11 [Subtract 5 from both side]
x = 6

Which system of equations has no solution?
O 5x+5y = 10 and 2x+2y=4
O 3x-6y = 4 and - 4x+8y=7
O 6x+2y = 6 and 7x+3y=9
O 3x-4y = 16 and 2x+3y = 5
Answer:
the first one or the last one
Step-by-step explanation:
5x+5y = 10 and 2x+2y=4
0 = 0
3x-6y = 4 and - 4x+8y=7
0 = 37 / 3
6x+2y = 6 and 7x+3y=9
0 = 3
3x-4y = 16 and 2x+3y = 5
x=4 and y=−1
The probability event A is .45, the probability of event B is.20. If A and B are independent events, what is the probability of A and B, P(A and B)?
0 2.25
25
.65
.09
Answer:
.09
Step-by-step explanation:
To find the probability of independent events, you multiply their individual probability.
so, .45 x .20 = .09

Luis is 0.25 meters shorter than Harry, if Luis is 1.7 meters tall determine Harry’s height.
Answer: 1.95
Step-by-step explanation:
Luis is Harry's height minus 0.25m, which means Harry is Luis' height plus 0.25m.
Luis + 0.25 = Harry
1.7 + 0.25 = 1.95 m
Mrs. Berry is purchasing a juicer which regularly sells for $390. She has a coupon for a 25% discount. The sales tax in her area is 7.5%. What will be the final cost of the juicer?
A $104.81 B $419.25 C. $314.44 D. $392.38
Answer:
C. $314.44
Step-by-step explanation:
$390 x 0.25 Discount = $97.5
$97.5 x 1.075 Sales Tax = $104.81 <---this is how much you save
$390 - $104.81 = $314.44 Total Price
Savings: $104.81
Tax: $21.94
Total Payment: $314.44
I need help Please help thank you <3
Answer:
Step-by-step explanation:
We start by finding what is inside the parenthesis, following the rules of pemdas we do 10 to the 6th power first, which comes out to be 1000000, we substitute this in instead of 10 to 6.
so we now have:
800.5x(2x1000000 )
Than finishing the parenthesis we multiply by 2
800.5x 2000000
than all you do is convert 800.5 to a decimal and 2000000 to an exponent, your teacher should have given you a chart or step by step directions for this part.
Have a great day!
Please help me understand this question.
Billy wants to hire a plumber to fix a faucet at his house. The plumber charges $125 initial fee and $85 per hour he is working.
Answer:
85x + 125 = y
Step-by-step explanation:
Let x = the amount of hours worked
Let y = the total cost to pay for this plumber
85 is the hourly pay so we multiply by the amount of hours worked to find the cost per hours. We then add that to the initial cost of 125 and we get the total cost.

Answer:
Step-by-step explanation:
The total number of triangles is 5
The total number of all shapes is 13
The ratio is triangles to total
The ratio is 5 to 13
Note
This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.
All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.
Simplify these calculations, leaving your answer in index form.
x5^5 ÷ x5^5

i have two questions
question 1:
N% of 15 is 6
Question 2:
18 is N% of 32
Whats the answer?
Answer for question 1 is Percentage Calculator: 6 is what percent of 15? = 40.
Answer for question 2 is What is 18 percent (calculated percentage %) of number 32? Answer: 5.76.
hope it helps. Please mark me Brainleist please.
Answer:
1. 40%
2. 56.25%
Step-by-step explanation:
1. N% of 15 = 6
N/100 x 15 =6
N = (6 × 100)/15
N = 40
2.N% of 32 = 18
N/100 x 32 = 18
N = (18 x 100) /32
N= 56.25

Factor the equation. [tex]x^2-x-12[/tex]
Answer:
(x - 4)(x + 3)
Step-by-step explanation:
Given
x² - x - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the x- term (- 1)
The factors are - 4 and + 3, since
- 4 × + 3 = - 12 and - 4 + 3 = - 1, then
x² - x - 12 = (x - 4)(x + 3) ← in factored form
