Answer:
r=5
Step-by-step explanation:
1.simplify both sides of the equation.
2.substract 2r from both sides.
3.substract 12 from both sides.
4.multiply both sides by 5/(11)
5. your answer will be 5.
r=5
Answer:
It is not a right angled troagle
Step-by-step explanation:
Given
Sides: 5m, 7m and 9m
Required
Is it a right angled triangle?
A triangle is right angled if:
Where a is the longest side and b,c is any of the other.
So, we have:
Since they're not equal then it is not a right angled troagle

Answer:
They do not form a right triangle
Step-by-step explanation:
The slope from a table can be found by finding what number keeps adding on new points. (horrible wording sorry)
EXAMPLE:
x y
0 2
1 4
2 6
3 8
4 10
for the X values it keeps adding by 1 and the Y values keep adding by 2. Since the slope is the change in y over x the slope would be 2/1 therefore simplifying to a slope of 2. To find the y intercept, you have to look for a value in which the X value is 0. From the table, this would be 2 so the y int is (0,2)
