Answer:
Step-by-step explanation:
f⁻¹(x) is the inverse of f(x).
y = 4x − 9. To find the inverse, switch x and y and solve for y.
x = 4y − 9
x + 9 = 4y
y = (x + 9) / 4
So the inverse function is:
f⁻¹(x) = (x + 9) / 4
Hello!
You find the area of all three shapes and add them together
We can do the one on the left first
To find the area we multiply the sides
8 * 7 = 56
The one on the left has an area of 56 ft squared
Now lets do the one on the right
8 * 7 = 56
The one on the left has an area of 56 ft squared as well
Finally lets do the one in the middle
We first have to find the length
8 + 12 = 20
Now we multiply
20 * 20 = 400
The middle one has an area of 400ft squared
Now we add them together
56 + 56 + 400 = 512
The answer is 512ft squared
Hope this helps!
Answer:
Ariel answer is wrong.
Step-by-step explanation:
Given that Ariel had done a Math problem for a triangle with sides
9,15 and 12. She concluded that these sides are not that of a right triangle.
To check whether Ariel is right:
Greater side = 15
Hence greatest angle will be opposite 15
Let us check pythagorean theorem
smaller sides are 9 and 12
Square and add them
9 square +12 square = 81+144 = 225 =15 square
We find that Pythagorus theorem is satisfied
Hence it is concluded that the triangle is right angled and Ariel was wrong
