350 / 28 = 12.5 gallons, so 13 gallons needed

13 X 2.5 = $32.50

Geri believed the answer to one of her homework problems was 2 cubed. After checking her work, she realized the correct answer w
TiliK225 [7]

Answer:

The correct answer is 64 times Geri’s original answer

Step-by-step explanation:

Given

Gari's Answer: 2³

Correct Answer: 2⁹

Required:

Relationship between both answers

Let Gari's answer be represented by G and the Correct answer be represented by C; Such that

G = 2³

C = 2⁹

Divide C by G

\frac{C}{G} = \frac{2^9}{2^3}

From law of indices, \frac{a^m}{a^n} = a^{m-n}

Applying this law, we have

\frac{C}{G} = 2^{9-3}

\frac{C}{G} = 2^{6}

\frac{C}{G} = 2*2*2*2*2*2

\frac{C}{G} = 64

Multiply both sides by G

G * \frac{C}{G} = 64 * G

C = 64G

Hence, we can conclude that the correct answer is 64 times Geri’s original answer

The slope of a line is 0 and it contains the point (3,1)
Sedaia [141]

Answer:

<h2>y = 1</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

<em>m</em><em> - slope</em>

<em>(x₁, y₁)</em><em> - point on a line</em>

We have <em>m = 0, (3, 1) → x₁ = 3, y₁ = 1</em>.

Substitute:

y-1=0(x-3)

y-1=0      <em>add 1 to both sides</em>

y=1

Other method.

If the slope is equal 0, then it's a horizontal line.

The equation of a horizontal line: <em>y = a</em>.

We have the point on a line (3, 1) → x = 3, y = 1.

Therefore the equation is <em>y = 1</em>.

What is the slope of the line given by the equation y= -3x
galben [10]

Answer:

-3

Step-by-step explanation:

The given equation is in slope intercept form.

The form is y=mx+b

This is where "m" is the slope, and "b" is the y intercept.

So in this equation, m=-3.

Therefore, the slope is -3.
