Question 1
Equation (1) y = x + 6
Equation (2) y = 2x + 4
Equation (3) y = 3x + 2
Equation (4) y = 5x – 4
The table above shows four equations. If x = 2, which equation has a y-value different from the other three equations?

Answer:

x=50

Step-by-step explanation:

That is becasue they are in the same spot on different parallel lines.

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.

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.

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.

Step-by-step explanation:

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]

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.

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.

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

3. m = 3

1. x = -2.16 or [tex]-2\frac{1}{6}[/tex] or 13/6

2. x = -1/4 or -0.25

3. m = 3

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
