In the figure, lines 1, m, and n are parallel. A classmate says you can use the corollary to the side-splitter theorem to find x

kkurt [141]

Answer: Your classmate incorrectly identified the sides that are proportional in the side-splitter theorem.

In this theorem, the segments formed on the traversal are proportional. However, in the diagram your friend is trying to prove that segments on the parallel lines are proportional. If he wanted to do that, he would need to have a different plan.

A function is given. g(x) = 6 x ; x = 1, x = a. determine the net change between the given values of the variable.

Pavlova-9 [17]

The net change between the given values of the variable is 6a - 6

<h3>How to determine the net change between the given values of the variable?</h3>

The given parameters are

g(x) = 6x

Where

x = 1 and x =a

Calculate g(1) and g(a)

So, we have

g(1) = 6 * 1

g(1) = 6

g(a) = 6 * a

g(a) = 6a

The net change between the given values of the variable is

Change = g(a) - g(1)

So, we have

Change = 6a - 6

Hence, the net change between the given values of the variable is 6a - 6

joe weighs 20lbs.less yhantwice jeffs weight.if jeff would gain 10lbs.,then together they wouldweigh 250lbs. how much does each

masya89 [10]

So,

Let x represent Joe's weight and y represent Jeff's weight.

"Joe weighs 20 lbs. less than twice Jeff's weight."
x = 2y - 20

"If Jeff would gain 10 lbs., then together they would weigh 250 lbs."
(y + 10) + x = 250

We now have our two open sentences.
x = 2y - 20
(y + 10) + x = 250

Get rid of parentheses.
x = 2y - 20
x + y + 10 = 250

We will use Elimination by Substitution.
2y - 20 + y + 10 = 250

Collect Like Terms.
3y - 10 = 250

Add 10 to both sides.
3y = 260

Divide both sides by 3.
$Jeff's\ weight = 86 \frac{2}{3} \ lbs.$

Substitute again.
$x = 2(86 \frac{2}{3} )-20$

Multiply.
$x = 173 \frac{1}{3} -20$

Subtract.
$Joe's\ weight = 153 \frac{1}{3}\ lbs.$

Check.

"Joe weighs 20 lbs. less than twice Jeff's weight."
Jeff's weight times two is 173 and one-third.
20 lbs. less than that is 153 and one-third lbs. Check.

"If Jeff would gain 10 lbs., then together they would weigh 250 lbs."
86 and two-thirds + 10 = 96 and two-thirds.
96 and two-thirds + 153 and one-third equals 250 lbs. Check.

$Joe's\ weight\ is\ 153 \frac{1}{3} \ lbs.$
$Jeff's\ weight\ is\ 86 \frac{2}{3} \ lbs.$
