Answer:

Step-by-step explanation:
To find the value of y, you can create an equation where two parts of the line are equal to the whole line:

Substitute given values:

Solve for y. Simplify parentheses:

Combine like terms to simplify the equation:

Get the variable on one side of the equation and the constants on the other. Add 9 to both sides:

Subtract 9y from both sides:

Isolate the variable. Divide both sides by 10:

The value of y is 2. Insert this value into each line segment value and solve:



:Done
You can check by using:

This statement is true, so the values are correct.
Answer:
6x³ - 8x + 9
Step-by-step explanation:
Step 1: Write out expression
2x + 7 + 6x³ - 1 + 3 - 6x - 4x
Step 2: Combine like terms (x)
6x³ - 8x + 7 - 1 + 3
Step 3: Combine like terms (constants)
6x³ - 8x + 9
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=Kx
where
K is the constant of proportionality or slope of the linear equation
In this problem
x ----> is the number of months
y -----> is the total amount savings
we have the ordered pairs
(4,80) and (7,140)
so
Find the value of K
K=y/x
For (4,80)
K=80/4=20
For (7,140)
K=140/7=20
The value of K is the same for both ordered paits
that means------> is a proportional relationship
therefore
the linear equation is
y=20x
the answer is the option A, C and D
Answer: 5^5
Step-by-step explanation:
Since 5x5x5x5x5 = 3,125
Find the TWO places where the graph crosses the x axis;. solve; find the roots; find the zeros; it is entirely possible that the equation has no real roots meaning it has imaginary or complex roots
