Answer:

a. One solution

Step-by-step explanation:

These are two linear equations with different x-coefficients. They have one solution.

__

<em>Additional comment</em>

If the x-coefficients are the same, the system may have 0 or infinite solutions, depending on the constants. It is not possible for a system of linear equations to have exactly two solutions.

You are installing a wood fence. The fence is 120 feet long. East wood slat to be installed vertically, is 3 3/4 inches wide. Wh

ddd [48]

3 3/4 inches = (3 3/4 / 12) feet = 0.3125 feet
120 feet requires ------- x number of board.

120 feet/0.3125 feet / board = 384 boards.

1 board costs 1.40
384 boards cost x

1.4 * 384.00= x*1 = x
537.60 dollars.

Note if you need to do this by dimensional analysis, it will look like this.

120 feet/fence [ 1 board / 3.75 inches] [ 12 inches/foot] [1.40 dollars / board]

All units that can be cancelled should be.
The result is 537.6 dollars / fence which is the answer you got.

Marty and Ethan both wrote a function, but in different ways.

lisabon 2012 [21]

Answer:

Marty's function has larger slope as compared to Ethan's slope.

Step-by-step explanation:

Marty function:

y plus 3 equals StartFraction 1 Over 3 EndFraction left-parenthesis x plus 9 right-parenthesis.

Writing in mathematical form: $y+3=\frac{1}{3}(x+9)$

Marty has written expression in point-slope form: $y-y_1=m(x-x_1)$ where m is slope

So, comparing Marty's equation with general point-slope form equation we get slope $m=\frac{1}{3}\:or\: 0.3$

Now, Ethan has a table

x y

-4 9.2

-2 9.6

0 10

2 10.4

We can find slope using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Using any two points, we can find slope of Ethan's equation

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{9.6-9.2}{-2-(-4)} \\Slope=\frac{0.4}{-2+4} \\Slope=\frac{0.4}{2} \\Slope=0.2$

So, we get Marty's slope = 0.3

Ethan's slope = 0.2

So, Marty's function has larger slope as 0.3 is greater than 0.2
