Antonio needed a loan worth 5,600. If the bank calculates interest at 3.1% compounded semi annually how much does he owe in 3years?
write the equation fully simplified slope intercept form
Answer:
y = -1/5x - 1
Step-by-step explanation:
The line crosses the y axis at -1, making it the y-intercept.
Since the line is going downwards from left to right, we know that it is a negative slope.
The line goes down one and 5 right. That makes the slope -1/5.
The equation is y = -1/5x - 1

thabo rounded the number of marbles to the nearest 5. His answer was 340. write down 2 possible numbers for the actual number of marbles.
Answer:
338 or 335 they both get rounded of to the nearest 5
2 possible numbers for the actual number of marbles 338 and 335, are rounded to the nearest 5.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, Thabo rounded the number of marbles to the nearest 5 and his answer was 340.
Therefore, 2 possible numbers for the actual number of marbles could be
Whether it's 338 or 335, both numbers are rounded to the nearest 5.

Answer:
J 3/4 cup
Step-by-step explanation:
Step 1: read and understand the question.
The question is giving you amounts of flour and 2 types of sugar.
The question is asking for a difference between two quantities:
the amount of flour (2 1/4 cups)the combined amount of sugar (3/4 cup white, 3/4 cup brown)Step 2: determine the relations you need to use to solve the problem
You need the combined amount of sugar, which you find by adding the quantities of each of the kinds.
3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined
You need the difference of that quantity from the quantity of flour, which you find by performing subtraction:
flour - sugar = (2 1/4) - (6/4) . . . . cups
Step 3: Use your knowledge of arithmetic.
(2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4
Step 4: Answer the question that was asked.
The difference between the flour and sugar amounts is 3/4 cup.

Let f(x)=x2+3x+2.
What is the average rate of change of f(x) from 3 to 6?
−112
12
−12
112
Answer:
12
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 3, 6 ] , then
f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56
f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then
average rate of change = [tex]\frac{56-20}{6-3}[/tex] = [tex]\frac{36}{3}[/tex] = 12

Answer pls im desperate (10 pts) (how many solutions does this have)
Answer:
Step-by-step explanation:
Left side
4x + 2x - 10
6x - 10
Right side
6x - 12
Eventually when you equate these sides, you will get an absurd answer because the 6x term will be subtracted out on both sides
that means you get -10 = - 12
which destroys the whole concept of equality. There is no solution.
Given a polynomial f(x), if (x − 4) is a factor, what else must be true? f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0
Question:
Given a polynomial f(x), if (x − 4) is a factor, what else must be true?
f(0) = 4 f(0) = −4 f(4) = 0 f(−4) = 0_______________________________________
Solution:
f(x) is a polynomial.
(x - 4) is a polynomial of f(x).
By converse of factor theorem: If (x - a) is a factor of f(x), then, f(a) = 0.
On comparing (x - 4) with (x - a), we get,
a = 4So,
f(a) = 0
=> f(4) = 0

The new patio at Tonya's house is 5 yards long by 10 feet wide. She is going to cover the patio with square bricks that measure 1 foot on each side. If each brick costs $4, how much will Tonya pay for the bricks? A rectangle that is five yards long and ten feet wide A. $600 B. $120 C. $150 D. $200
Answer:
A
Step-by-step explanation:
Steps to take to determine the answer
Because the length is in yards, it has to be converted to footFind the area of the patio using the length and width measured in footDetermine the area of the square brickMultiply the cost of the brick by the area1 yards = 3 foot
5 x 3 = 15 foot
Area of a rectangle = length x breadth
15 x 10 = 150 ft^2
Cost = 150 x 4 = $600
6x ^ 2 + 96x - 13 = - 13
(X+A)^2=b
