180-this number or 360 because its a circumference
Answer:
(-∞,4)
Step-by-step explanation:
the value is going down from the right until it reaches the vertex
Find the slope of the line passing throught the points (2, 2) and (4, 3).
The formula of a slope:
Substitute:
If the point (x, -1) lie on the same line, then the slope of line passing through the points (2, 2) and (x, -1) the same:
Substitute:
We have the equation:
<em>cross multiply</em>
<em>add 2 to both sides</em>
<h3>Answer: x = -4.</h3>
Answer:12
Step-by-step explanation:
Let the numbers be a and b
a-3b=5 ........equation (1)
There product is :
ab=68 ..........equation (2)
From equation (1)
a-3b=5
Make a the subject of the formula
a=5+3b. ........equation (3)
Substitute equation (3) into equation (2)
(5+3b)b=68
3(b^2)+3b-68=0
The product is -204b^2(17 and -12)
(b+17)(b-12)=0
b=-17 or b=12
So the number is 12
