Answer:
Yes, since log(2) and log(5) both exist as valid values for the logarithm.
didnt check if ur equation is correct though
Answer: 7cm
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the length of the 3 sides together. Let the third side be x , then
x + 9 + 6 = 22
x + 15 = 22
Subtract 15 from both sides , that is
x = 22 - 15
x = 7
Therefore : the third side is 7cm
Answer: 4m-8
Step-by-step explanation:
Remember to distribute the negative sign!
m-8+3m
4m-8
Answer:
4
Step-by-step explanation:
The constant of proportionality is what determines the relationship between y and x. If t is the constant of proportionality then an example is y = tx .
So 4 is the constant of proportionality
Answer:
Please check the explanation.
Step-by-step explanation:
The midpoint (a, b) of line joining points (x₁, y₁) and (x₂, y₂)
a = x₁ + x₂ / 2
b = y₁ + y₂ / 2
Given that the midpoint of AB is (4, -3).
i.e. (a, b) = (4, -3)
Given that A has coordinate (1, 5).
i.e. (x₁, y₁) = (1, 5)
We have to determine the coordinates of B.
i.e. (x₂, y₂) = B
Thus,
4 = (1 + x₂)/2
(1 + x₂) = 4 × 2
1 + x₂ = 8
x₂ = 7
and
-3 = (5 + y₂)/2
(5 + y₂) = -3 × 2
5 + y₂ = -6
y₂ = -11
so (x₂, y₂) = (7, -3) = B
Thus, the coordinates of B = (x₂, y₂) = (7, -3)
Therefore,
x₂ + y₂ = 7 + (-3)
= 7 - 3
= 4
Hence, the value of x₂ + y₂ = 4
