Answer:
x = 26
Step-by-step explanation:
Since the triangle is right, use Pythagoras' identity to find x
x² = 24² + 10² = 576 + 100 = 676
take the square root of both sides
= 
, hence
x = 26
Answer:
5x+4y = 52
Step-by-step explanation:
We can first write the equation in point slope form
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
y - 8 = -5/4 ( x-4)
Multiply each side by 4 to get rid of the fraction
4(y - 8) = 4*(-5/4) ( x-4)
4(y - 8) = -5 ( x-4)
Distribute
4y - 32 = -5x+20
We want the equation in the form
Ax + By = C
Add 5x to each side
5x+4y -32 = -5x+5x+20
Add 32 to each side
5x+4y -32+32 =32+20
5x+4y = 52
I think it is y=4x because y is directly proportional to x
Answer:
Solution:
When X=2
f(2)=1/2
= 1/2
When X= 1
f^-1(1)= 2*1
=2
When X=2
f^-1(2)=2*2
= 4
Step-by-step explanation:
I don't know if these are correct and if that last question is f^-1(2) or not.
Answer: Because they have different slopes (1/3 and 1), they will only have 1 solution There is only one solution since they have different slopes.
Step-by-step explanation: hope it helps
