Answer:

$22.70

Step-by-step explanation:

First, find out how much 1 gallon costs. To do this, divide 15.89 by 7.

So, one gallon costs 2.27. Then multiply that by 10 to get 22.7.

In your first sentence, 7p = 26.88 is implied. Now, AN equation to find the price of one gallon--simply solve for p = 26.88/7; p = $3.84 per gallon.

Answer:y=3/2x-3

Step-by-step explanation: the slope of the graph is (y2-y1)/(x2-x1)

If we take points (0,-3) (2,0) the slope would be (0--3)/(2-0) = 3/2

And the y-intercept of the slope is -3

n200080 [17]

Answer:

16 or (4^2)

Step-by-step explanation:

4^3 * 4^-1

When multiplying exponents with the same bass, the exponents themselves can be added.

3 + -1 = 2

4^2 = 16

16 is your answer!

Determine the equation of the graph, and select the correct answer below.
Alinara [238K]

Answer:

The equation of the parabolic function is :

y=(x-1)^2-3

Step-by-step explanation:

The standard equation of a parabola is given by:

y=a(x-h)^2+k

where (h,k) represents the vertex of the parabola.

From the graph shown in figure we can find the vertex of the parabola which is the minimum point of parabola and lies st point (1,-3)

So, we can say:

(h,k)\rightarrow (1,-3)

Plugging in the values of vertex in standard equation of parabola,

y=a(x-1)^2+(-3)

Simplifying the equation:

y=a(x-1)^2-3

We can find value of a by plugging in a point from the graph.

Using point (0,-2) which lies on graph.

Plugging in the given point.

-2=a(0-1)^2-3

-2=a-3

Adding 3 to both sides.

-2+3=a-3+3

1=a

∴ a=1

Plugging in a=1, the equation of parabola can be written as:

y=(x-1)^2-3

The missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²

How to find the distance between two coordinates?

The formula for distance between two coordinates is;

d = √[(y₂ - y₁)² + (x₂ - x₁)²]

where;

(x₁, y₁) is the coordinate of the first point

(x₂, y₂) is the coordinate of the second point

Now, this distance formula can also be rewritten when we square both sides to get;

(y₂ - y₁)² + (x₂ - x₁)² = d²

Thus, the missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²
