Right triangle = Pythagoras theorem.
a^2+b^2=c^2
there's already c and b so
10^2-8^2=a^2
100-64= 36
a^2=36
square root both sides
to get 6.
Answer:
x=2 and y= -2
Step-by-step explanation:
Substitute y=x-4 in second equation
x-4=4x-10
get x terms on one side and numbers on other sides
4x-x=10-4
3x=6
divide 3 on both sides
x=2
substitute x=2 in y=x-4
y=2-4
y= -2
Answer: First, you need to figure out 22 times 2 = 44. Then, you need to multiply the original ratio by 44 to get the answer.

Answer:
(a) Growth

Step-by-step explanation:
Given
-- current
--- rate
Solving (a): Growth or decay
The question says his followers increases each day by 24%.
Increment means growth.
<em />
<em>Hence, it is a growth problem</em>
Solving (b): Equation to represent the scenario.
Since the rate represents growth, the equation is:

Substitute:
and
