This table gives a few (2,y) pairs of a line in the coordinate plane.
What is the y-intercept of the line?
Answers
Answer:1
Step-by-step explanation:the y is a place holder instead of the digit 1 because there is only one y. Whitch is the same reason why the 2 isn’t 2x because the 2 is a place holder for how many x there are. The problem is showing you how much value each place holders have. (x,y)

Answers
Answer:
K = $0.45
1____ 2__ 4 __5___10__ 15__ 20__ 100
0.45_0.9_1.8_2.25_4.5_6.75__9___45
Step-by-step explanation:
Given the data:
Number of pepper: 1 2 4 5 10 15 20 100
Cost :
Cost of 5 pepper = 2.25
Using variation :
Cost = number of pepper * k
K = CONSTANT of proportionality
k = cost / number of pepper
k = 2.25 / 5
k = 0.45
Hence,
Cost of pepper = k * number of pepper
Number of pepper:
Cost :

If two triangles are congruent then they are similar.
Answer:
False.
Step-by-step explanation:
Note the signs:
< is less than
> is greater than
= is equal too
≤ is less than or equal too
≥ is greater than or equal too
~
In this case, Kiran says that -2 is less than -5. However, if you look at a number line (in which the further left it is, the smaller the digit in value, while to the right, the greater the value), -5 is found to the left of -2. Therefore, -2 > -5.

what is the rate of change of y with respect to x for this function?
Answers
Answer:
Given the function: y=f(x) = 3x+2
when x=-2 at the beginning of the interval [-2, 5],
then;
y = 3x+2 begins at
y= 3(-2)+2 = -6+2= -4.
and
when x=5 at the end of the interval [-2, 5],
y = 3x+2 ends up at
y= 3(5)+2 = 15+2= 17.
So,
y has changed -4 to 17, which is a change of 17-(-4)= 17+4 = 21
and x has changed from -2 to 5, which is a change of 5-(-2)=5+2=7
So, the average rate of change of y with respect to x over the interval
[-2, 5] is given by ;
=
Therefore, the average rate of change y with respect to x over the interval is, 3

Suppose that $8000 is placed in an account that pays 11% interest compounded each year what's the amount after 1 year ? What's the amount in the account after 2 years
Answers
Answer:
A = $9,760.00
Step-by-step explanation:
I = A - P = $1,937.50
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.875%/100 = 0.03875 per year.
Solving our equation:
A = 10000(1 + (0.03875 × 5)) = 11937.5
A = $11,937.50
The total amount accrued, principal plus interest, from simple interest on a principal of $10,000.00 at a rate of 3.875% per year for 5 years is $11,937.50.

Choose 3 values for x that would make this inequality true. 24>2 (x+2)
Answers
Answer:
9, 2, 0
Step-by-step explanation:
Solving the inequality
24 > 2(x + 2) ← divide both sides by 2
12 > x + 2 ( subtract 2 from both sides )
10 > x
Thus we require values of x that are less than ( but not equal to ) 10

Answers
Answer:the second one
Step-by-step explanation:
y1= log 3 etc so it the second one
The correct system of equations which can represent the equation are,
⇒ y₁ = log (x + 3) / log 4
⇒ y₂ = log (2 + x) / log 2
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ log₄ (x + 3) = log₂ (2 + x)
Now, We know that;
The formula is,
logₐᵇ = log b / log a
Hence, By using above rule we get;
The correct system of equations which can represent the equation are,
⇒ log₄ (x + 3) = log (x + 3) / log 4
⇒ log₂ (2 + x) = log (2 + x) / log 2
Thus, The correct system of equations which can represent the equation are,
⇒ y₁ = log (x + 3) / log 4
⇒ y₂ = log (2 + x) / log 2
