Answer is C
Step-by-step explanation:
First Jackie needs to save $125
y = 125
He already saved $35, this is our constant

At its maximum speed, a motorboat can travel 10 miles downstream on a river in 20 minutes. It takes 30 minutes for the boat to travel back upstream the same 10 miles, also at maximum speed.
Write a system of two equations that could be used to find the maximum speed of the motorboat in still water. Let b represent the maximum speed of the motorboat in miles per hour and let r represent the speed of the river's current in miles per hour. Convert the times into hours. Solve the system of equations for b and r to determine the boat's maximum speed in still water and the speed of the river's current.

Answers
Answer:
x = 17
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-243 = -9(10 + x)
Step 2: Solve for x
Divide -9 on both sides: 27 = 10 + xIsolate x: 17 = xRewrite: x = 17Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -243 = -9(10 + 17)Add: -243 = -9(27)Multiply: -243 = -243Here we see that -243 does indeed equal -243.
∴ x = 17 is the solution to the equation.

An equation and the first step in its solution are shown.
Equation: x2 + 3x – 9 = 0
Step 1: x2 + 3x + h = 9 + h
What value of h is used to solve the equation by the method of completing the square?
Answers
Answer:
The answer is either 1.5 or 0.667
Step-by-step explanation:
x2+3x-9=0
x2+3x=9
6x=9
x=1.5
or
x=667
the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]
Given :
An equation and the first step in its solution are shown.
Equation: [tex]x^2 + 3x -9 = 0[/tex]
Step 1: [tex]x^2 + 3x + h = 9 + h[/tex]
In completing the square method , we take the coefficient of x and divide it by 2 and then square it
coefficient of x is 3
divide it by 2 , so we get [tex]\frac{3}{2}[/tex]
Then we square it [tex](\frac{3}{2} )^2\\\frac{9}{4}[/tex]
Then we add it on both sides of the equation
[tex]x^2 + 3x + \frac{9}{4} = 9 + \frac{9}{4}[/tex]
So, the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]
