Answer:
30.1%
Step-by-step explanation:
The increase in price (markup) is ($3.45 - $2.65) = $0.80.
The increase in price (as a decimal fraction) is 0.80/2.65, or 0.301; as a percentate, this is 30.1%
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.

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.

simplify 2(x + 5) − 3(x − 2)
Answer:
-x + 16
Step-by-step explanation:
We need to use the distributive property to solve this!
We can isolate this into 2 parts that we will need to combine later on, but isolating them will make it less confusing to simplify:
2(x+5) is one part, and the second is -3(x-2)
The first part simplifies to 2x + 10, and the second simplifies to -3x + 6. Now we need to combine the 2 values.
2x + 10 - 3x + 6
Combine like terms
-x + 16 is your answer!
Answer:
Step-by-step explanation:
2x+10 - 3x -5 and for the fun of it the answer will be..
you will subtract 10 and 5 and that gives you 5
then you do -3+2 = -1x
5 divided by -1 gives you
X= -5

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

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
