8 gallons/340 miles vs. 7 gallons/350 miles
$32/340 miles vs. $28/350 miles
$1.133/1 miles vs. $0.08/1 mile
113 cents/mile vs. 8 cents per mile

113 cents- 8 cents = 105 cents

The answer is 105 cents/mile.

What is a linear equation in math?

  • A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
  • When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
  • There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.
  • Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

\frac{3^{2} * 3^{-5}  }{4^{2} } = \frac{3^{-3} }{4^{-2} }

\frac{1}{3^{3} }  ÷  \frac{1}{4^{2} }

\frac{1}{27} * 16  = \frac{16}{27}

Anon25 [30]

Answer:

A. -16x²+64x+8

B. 72 ft.

Step-by-step explanation: A. Expand the perfect square binomial -16(x²-4x+4)+72, dist. -16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)

B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.

What are the slope and y-intercept for the graph of y – 3x = -1?
Liula [17]

Answer:

Slope (m) = 3, y-intercept (b) = -1

Step-by-step explanation:

First, we need to write the equation in y = mx + b.

To do this, add 3x to both sides.

y = 3x - 1 is your result.

Now, we have everything we need to do determine our slope and y-intercept in just this equation alone.

Remember, m = slope and b = y-intercept.

In this equation:

m = 3

b = -1

So your slope is 3, and your y-intercept is -1
