Answer:
(-2,10)
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−8x=20
Step 1: Subtract 20 from both sides.
x2−8x−20=20−20
x2−8x−20=0
Step 2: Factor left side of equation.
(x+2)(x−10)=0
Step 3: Set factors equal to 0.
x+2=0 or x−10=0
x=−2 or x=10
Answer:
x=−2 or x=10
Answer:
{–2, 10}

Step-by-step explanation:
Answer:
x=5
Step-by-step explanation:
∠17x+5≅∠18x
17x-18x=-5
-x=-5
x=5
17x5+5=90°
18x=90°

Answer:
C) (0,5)
Step-by-step explanation:
f(x) is y and x is x
The table is providing you with points
y-y over x-x gives you a slope of -5
Use the points and turn it into a point-slope equation and convert to y-intercept equation
y-15=-5(x+2)
y-15=-5x-10
y=-5x+5
So the y-intercept is 5 or (0,5)
A ride at an amusement park has two options for cars, one that holds 6 passengers and one that holds 3 passengers. If the ride designer wants to make sure that each run holds at least 12 passengers, which graph represents the overall equation and shows the possible combinations of the number of 6-passenger cars, x, and the number of 3-passenger cars y (not all points may not apply to the scenario)?

Answer:
Step-by-step explanation:
To graph that you would start at 4 because that's your y-intercept then you would move down by 1 because z is considered 1 and the negative is only applied to the rise and the run is 3 so from point 3 you would move to the right 3 times and that would be your second point.

Todd purchased 8 gallons of gasoline for $30. The equation y = 3.68x represents the cost in dollars, y, Hope paid for purchasing x gallons of gasoline. Which statement is true?
A
Todd paid $0.07 more per gallon of gasoline than Hope.
B
Todd paid $0.07 less per gallon of gasoline than Hope.
C
Todd paid $0.08 more per gallon of gasoline than Hope.
D
Todd paid $0.08 less per gallon of gasoline than Hope.
Answer:the answer would be A
Step-by-step explanation:
30 divided by 8 = 3.75 which is the ammount of money per galon that Todd spent. There is a 7 cent difference between the ammount todd payed per gallon and the ammount Hope payed for gallon.
Todd paid $0.07 more per gallon of gasoline than Hope is the correct alternative.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that Todd purchased 8 gallons of gasoline for $30. The equation y = 3.68x represents the cost in dollars, y, Hope paid for purchasing x gallons of gasoline.
Unit rate of gasoline in case of Todd will be -
{T} = (30/8) = $3.75
Unit rate of gasoline in case of Hope -
{T} = (30/8) = $3.68
We can write -
$3.75 - $3.68
$0.07
Therefore, Todd paid $0.07 more per gallon of gasoline than Hope is the correct alternative.

Graph the parabola.
y=3(x-2)²+1
Plot five points on the parabola: the vertex, two points to the left of the vertex, and two points to the right of the vertex. Then click on the graph-a-function
button.
A parabola is a curve with a focus and a directrix. The focus is any point is at an equal distance while the directrix is a fixed line. The vertex of the parabola is (2,1), the two points to the right are (3,4) & (4,13) while the two points to the left are (1,4) & (0,13).
Given that:
[tex]y = 3(x - 2)^2 + 1[/tex]
A parabola is represented as:
[tex]y = a(x - h)^2 + k[/tex]
Where:
[tex]Vertex = (h,k)[/tex]
So, by comparison; the vertex of the function is:
[tex]Vertex = (2,1)[/tex]
To plot two points to the right, we select x values greater than 2.
Let: [tex]x = 3[/tex]
So, we have:
[tex]y = 3(x - 2)^2 + 1[/tex]
[tex]y = 3(3 - 2)^2 + 1[/tex]
[tex]y = 4[/tex]
Let [tex]x = 4[/tex]
[tex]y = 3(x - 2)^2 + 1[/tex]
[tex]y = 3(4 - 2)^2 + 1[/tex]
[tex]y =13[/tex]
To plot two points to the left, we select x values less than 2.
Let: [tex]x=1[/tex]
So, we have:
[tex]y = 3(x - 2)^2 + 1[/tex]
[tex]y = 3(1 - 2)^2 + 1[/tex]
[tex]y = 4[/tex]
Let [tex]x = 0[/tex]
[tex]y = 3(x - 2)^2 + 1[/tex]
[tex]y = 3(0 - 2)^2 + 1[/tex]
[tex]y =13[/tex]
In conclusion:
The vertex of the parabola is (2,1)The two points on the right are (3,4) and (4,13)The two points on the left are (1,4) and (0,13)See attachment for graph

What is the equation of the line that passes through the point (2,-6) and has a slope of -1?
Answer:
y = -x - 4
Step-by-step explanation:
Plug in the point and slope into the equation y = mx + b, and solve for b:
y = mx + b
-6 = -1(2) + b
-6 = -2 + b
-4 = b
Then, plug in b and the slope into y = mx + b
y = -1x - 4
y = -x - 4 is the equation of the line
Find the slope of the line in the simplest form.
A. m= 5/1
B. m= -1/5
C. m= -0.2
D. m= -5/1
Write an equation of the line in slope-intercept form (0,-2) ,(2,2)
Answer:
y=2x-2
Step-by-step explanation:
Slope intercept Formula: y=mx+b
y= Y coordinate
m = slope
x = x coordinate
b = y intercept
Point Slope Formula: y-y1=m(x-x1)
Slope Formula: m= y2-y1 / x2-x1
2 - (-2) / 2-0 = 4 / 2 = 2
y- (-2) = 2 (x - 0) = y+2=2x-0
y=2x-2
22. Jack bought a tree to plant in his front yard. The tree grows at an approximate rate of 9 inches per year. After 4 years, the tree is 5 feet tall. Write an equation in slope-intercept form to find the height (in feet) of the tree, y, after x years.
Answer:
y=9x+60
Step-by-step explanation:
An equation in slope-intercept form to find the height (in feet) of the tree, y, after x years is y=9x+60.
Given that, the tree grows at an approximate rate of 9 inches per year.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
We know that, 1 feet =12 inches
So, 5 feet =60 inches
Let the height of the tree be y and the number of years be x.
Now, equations is y=9x+60
Therefore, an equation in slope-intercept form to find the height (in feet) of the tree, y, after x years is y=9x+60.
