(a,7) lies on the equation of 5x-y=8, that means we solve for x when y=7.
5x-(7)=8
5x=8+7=15
x=3
=>
a=3
This should give you all you need to know
I have attached a screenshot for the complete question.
Answer:
A. g is the dependent variable
Explanation:
The given equation is:
g = 748 u
We can see that in this equation, we are converting the gallons into units.
Let's check each variable:
u depends on the usage of each consumer. Therefore, it does not depend on g in this equation. This means that u is the independent variable
g depends on the input u from the consumer. Therefore, g is the dependent variable in this equation.
Hope this helps :)
Answer:
(D)Equilateral Triangle
Step-by-step explanation:
Given a circle centre M; and
The measure of major arc JL = 300 degrees
The triangle formed by radii ML and MJ and chord JL is Triangle JLM.
Since ML=MJ (radii of a circle), the base angles are equal.
Therefore:

We can see that all the angles of triangle JLM are 60 degrees, therefore Triangle JLM is an Equilateral Triangle.
