Answer:
see attached
Step-by-step explanation:
A graphing calculator can show you the graph right away. Or you can plot it by hand.
Since both inequalities do <em>not</em> include the "or equal to" case, the lines they represent (y=-x-1, y=x+4) will be dotted lines.
Of course, you can read the y-intercept from the equation. (It is the constant, the value of y when x=0.) The slope is the coefficient of x, so is -1 for the line with the negative y-intercept, and +1 for the line with the positive y-intercept.
The solution to each inequality is shaded. For y < ( ), the shading is below the dotted line. For y > ( ), the shading is above the dotted line. Then the solution to both inequalities is the doubly-shaded area.
The right answer for the question that is being asked and shown above is that:
The value in the x axis will be the Year.
The value in the y axis will be the Year Profit.
The increment on the x axis will as is.
The increment on the y axis can either be $50,000.
Answer:
24 gallons per hour
Step-by-step explanation:
Connor filled his 150-gallon pool with water in 6.25, to find out how many gallons per hour he used, we have to divide the amount of gallons into every hour. Therefore:
150/6.25
24 gallons per hour.
Answer:
x = 2.36603 or 0.633975
Step-by-step explanation:
Here we want to solve the quadratic equation using the completing the square method.
2x^2-6x + 3 = 0
divide through by 2 first;
x^2 -3x + 3/2 = 0
x*2 -3x = -3/2
Half the x term will be -3/2 and squaring it is 9/4
we add this to both sides
x^2-3x/2 + 9/4 = -3/2 + 9/4
(x-3/2)^2 = 3/4
Finding square root of both sides
x-3/2 = √(3/4)
x = 3/2 ± √(3/4)
x = 3/2 + √(3/4) or x = 3/2-√(3/4)
which becomes
x = 2.36603 or 0.633975
