Answer:

Step-by-step explanation:
Given data:
2, 5 , 7
The geometric mean is a measure of central tendency of a data set which utilizes the product of their values
To find the geometric mean of the given values;
- multiply them together
- find the square root;
Geometric mean =
Geometric mean = 
Answer:
the answer is 1 & 32/99 (131/99)
To find the value of r
We will follow the steps below
Usinf the equation of a slope:
slope(m) =

from the question given;
m= -3/4
x₁ = 3
y₁=4
x₂=-1
y₂=r
substituting the values into the slope formula

we can now simplify and then solve for r

cross-multiply
-3 x -4 = 4(r-4)
12 = 4(r-4)
Divide both-side of the equation by 4

3 = r - 4
add 4 to both-side of the equation
3+4 = r-4+4
7 = r
r=7
Therefore the value of r is 7
-43x + 16 < 79
Subtract 16 from both sides,
-43x < 63
Divide -43 from both sides,
x < -63/43
Hope this helps!
