This is so easy that it's confusing, and NOBODY ever gets it right
the first time they see it.
Inside the parentheses are two numbers. The first number is a value
for 'x', and the second number is a value for 'y', and they have to be
numbers that when you put them into the equation in place of 'x' and 'y',
the equation becomes a true statement.
In this problem, you already know what 'x' is ... it's -1 . Now, can you find
a value for 'y' that makes the equation true ?
Let me ask you that question again. It's <em>very, very important</em>:
The equation is . . . . . <em>Y = 8</em> . . . . . Can you find a value for 'y' that makes
this equation a true statement ?
Do you give up ?
Well, how about ' 8 ' ?
If you put ' 8 ' in place of 'y' in the equation, then the equation says . . . 8 = 8 . . . and that's true !
In fact, if you put <u>any other number</u> except '8' in place of 'y', then the
equation is <em>not </em>true. 'Y' must be 8 . It doesn't matter what 'x' is.
'X' is not even in the equation. It has no effect on 'y'.
'X' and 'y' don't even know about each other. They're not related in
any way, and nobody cares what 'x' is.
'Y' is ALWAYS 8 ... that's exactly what the equation is telling you . . . <em>Y = 8</em> .
2x-3=6
2(3)-3=6
multiply the parenthesis
6-3=6
I hope this helped (:
Answer:
Answer to question 8 is : Area =1017.88 and Circumference =113.1
Answer to question 9 is: Area =490.87 and Circumference =78.54
Step-by-step explanation:
8. i just did πr2for area and for circumference i did 2πr which is just the equation to find each
9.i found that half of the diameter is 12.5 so i did πr2 to find the Area i filled in the radius and pai and 2πr for circumference filled in the pai and radius
oh also round it if u want
plz give me brainliest and rate it that u and goodluck
Answer:
24 = x
Step-by-step explanation:
You use Pythagorean theorem. Since the normal equation is 
, you already have the 
and another side which can be 
or 
.
Because you have the hypotenuse and a side , your equation looks like this now: 
and when you solve for be you just subtract 
to get 24.
