PLEASE HELP ME OLEASE UT URGENT !

Answers

Answer:

Explanation:

m = (y1 - y)/(x1 - x)

y1 = 50, y = 90
x1 = 2, x = 4

m = (50 - 90)/(2 - 4)
m = -40/-2
m = 20

b is the y intercept = 50

So our equation is written as:

y = 20x + 50

The graph represents the relationship between x (the number of owls fed) and y (the number of rev dollars spent). What is the amount of money that will be spent to feed 10 owls? pls hurry

Answers

Answer:

Step-by-step explanation:

Since this is a test/homework, I'll give you a hint.

For a linear graph, if you took a ruler, and traced the "dots", it should always be in a straight line.

Another way, is finding a pattern. I can't really explain this so much, since it's fairly basic. Just find two dots, and see if they are similar in any way. If they are, good job! Find another. If their isn't, maybe try searching for another.

The third way: You could use the equation mx+b=y, but this is just a bit ridiculous for this problem, since you could just eye it.

Hope this helps!

Reasoning Explain why either a or b must be 0 if ab = 0, but neither a nor b
must be 4 when ab = 4.

Answers

By the zero product property, a or b must be 0 if ab = 0. Or you could solve for each variable.

Divide both sides by b:
b=0/a —> b=0

Divide both sides by b:
a=0/b —> a=0

Hmm A could be 4 and b could be 1 because 4*1=4

How do I find x in this problem?

Answers

Answer:

125

Step-by-step explanation:

Since its a hexagon the interior angles equal to 720 degrees.

Because (n-2)180 equals the number of sides. So, (6-2)180 = 720.

Now for x,

120 + 130 + 100 + x + 135 + 110 = 720

595 + x = 720

x = 125

x + 5 = 29
