i might be wrong though
answer:
y = 2x - 5
work:
to write equations, we use the format y = mx + b.
m stands for the slope, and b stands for the y intercept.
this means that you should be able to enter the values for y and x and get a valid equation as a result.
in this equation, we are not given a y intercept value, but we do have a slope and x and y values, so we have to solve by substituting.
so, let's substitute in the values of y and x and the slope,
and solve for b, the y intercept.
1 = 2(3) + b (multiply 2 x 3)
1 = 6 + b (subtract 6 from both sides)
- 5 = b
b has a value of -5. let's place this into the equation.
y = 2x - 5.
the slope is 2, and the y intercept is -5, let's plug in our y and x values to verify that this is true.
1 = 2(3) - 5
1 = 6 - 5
1 = 1
so, this equation is correct. hope this helps and have a great day!
Answer:
4,702,000
Step-by-step explanation:
Answer:
The density of salt solution is 
.
Step-by-step explanation:
Given that,
Volume of certain solution, V = 7.5 litres
Mass of salt in solution, m = 37 grams
We know that, 
We need to find the density of salt in the solution. The density of salt is given by mass per unit volume. The formula can be written as:
So, the density of salt solution is .
