Answer:

Yes, they are parallel

Step-by-step explanation:

You can rewrite the second equation in slope intercept form to get your answer.

x-2y-8=0

-2y=-x+8

y=1/2x-4

Since the slope of this line is the same as that of the first, they are parallel. Hope this helps!

Answer:

see below

Step-by-step explanation:

Take the second equation and put it in slope intercept form

y = 1/2x+3

x -2y -8=0

Subtract x from each side

x-2y-8-x = 0-x

-2y -8 = -x

Add 8 to each side

-2y -8+8 = -x+8

-2y = -x+8

Divide each side by -2

-2y/-2 = -x/-2 +8/-2

y = 1/2 x -4

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

The slopes are the same and the y intercepts are different which means they are parallel lines. If they had the same slopes and the same y intercept they would be the same line

Answer:

The unit rate of $10 per hour.

Step-by-step explanation:

Given

$x = time$

$y = amount$

$(x,y) = (1,10)$

See attachment for graph

Required

What does the given point represents

From the attachment, the origin of the graph is:

$(x_1,y_1) = (0,0)$

and we have the given point to be:

$(x_2,y_2) = (1,10)$

Calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{10-0}{1-0}$

$m = \frac{10}{1}$

$m = 10$

The slope represents $10/1 hour

Hence:

$(x,y) = (1,10)$ means the unit rate is $10 per hour

Find the length of x. help please !

Answer:

x = 10

Step-by-step explanation:

Use CPCTC (Corresponding parts of congruent triangles are congruent).

Set the ratios:

$\frac{6.5}{5} = \frac{6.5 + 6.5}{x}$

First, simplify. Combine like terms:

$\frac{6.5}{5} = \frac{13}{x}$

Next, cross multiply.

$5 * x * \frac{6.5}{5} = \frac{13}{x} * x * 5\\x * 6.5 = 13 * 5\\6.5x = 65\\$

Isolate the variable, x. Divide 6.5 from both sides of the equation:

$\frac{(6.5x)}{6.5} = \frac{(65)}{6.5} \\\\x = \frac{65}{6.5}\\x = 10$

Check:

$\frac{5}{6.5} = \frac{x}{13}$

Plug in 10 for x (Your answer). Cross multiply, then simplify:

$\frac{5}{6.5} = \frac{10}{13}$

$13 * 6.5 * \frac{5}{6.5} = \frac{10}{13} * 13 * 6.5$

$13 * 5 = 10 * 6.5$

$65 = 65$ (True).

Jan began with 5/6 pound of modeling clay she used 1/5 of the clay to make decorative magnets. She divided the remaining clay in

lawyer [7]

Starting weight: 5/6 lb. Of this, Jan used 1/5, which would be (1/5)(5/6) lb,
or 1/6 lb, leaving 4/6 lb, or 2/3 lb. unused.

2/3 lb
Now divide 2/3 lb by 8 portions: ----------------- = (2/24) lb/portion, or
8 portions

1/12 lb/portion.
