Y varies inversely with x. If y = 40 when x = 16, find x when y =-5.

Answers

Answer 1

Answer: y varies directly with x m eans
y=kx where k is constant

y=40
x=16
find k
40=k16
divide both sides by 16
5/2=k

y=5/2x

y=-5 find x
-5=5/2x
times 2/5 both sides to cancle fraciton (5/2 times 2/5=10/10=1)
-10/5=x
-2=x

x=-2

Seed Mix A and Seed Mix B cost about the same. A graph measuring cost and bags. Two lines, labeled Seed Mix A and Seed Mix B, exit the origin to show that cost increases as bags increases

Answers

Answer:

seed Mix A is more expensive than Seed Mix B.

Step-by-step explanation:

The graph of Mix A is above the graph of Mix B.

Looking at the labels of the graphs, we see that the x-axis represents the number of bags bought and the y-axis represents the cost.

For every point along the x-axis, Mix A's cost is above Mix B's cost. This means that Mix A is more expensive.Step-by-step explanation:

I am a 3-digit number that is even. My hundreds and ones digits are the same and have a sum of 8. My tens digit is 2 less than my ones digit. What number am I ?

Answers

Let's start off with some key terms.

The number has 3 digits.
Even numbers end with 0, 2, 4, 6, or 8. (Obviously)

The hundreds digit and ones digit are the same.
First number in a 3 digit number is the hundreds, and the last number is the ones.

So, both of those two digits are the same and has to equal 8.

Well, $4+4=8$

The hundreds place and the ones place are 4.

The tens digit is the middle number in a 3-digit number.

It is two numbers less than the ones digit.
$4-2=2$

The number is 424.

$\bowtie$

424 I know because 4+4=8 and 4-2= 2 so I figured 424

Brenda observes that the keyboard and the screen of an open laptop lie on two different planes. In how many lines do the planes containing the keyboard and the screen intersect?

Answers

Let's assume the laptop is opened at 90 degrees (this is done for the sake of simplicity, is actually irrelevant) then each plane would be analogous to the 'x' and 'y' planes you see in a Cartesian Plane, which only intersect at one point called the Origin. Any two lines with different slopes will intersect only one time (if they're parallel they have the same slope)
