Ok so let's start by the basic, 7-4 is 3,and 5-2 is 3.The denominator stays the same so you're left with, 3 3/8
Using the information given, one can solve to find the equation of the line using slope intercept formula y=mx+b.
Given the y-intercept, b, 3.
y=mx+3
Next, we can plug in the given point (2,4), to solve for the slope.
4=m(2)+3
Subtract 3 from both sides.
1=2m
divide by 2.
1/2=m
So, given m and b, you can make your equation:
y=1/2x+3
I believe that is answer choice C. Hope this helps!
I thin the answer's B, 4/13
Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
Given
1. 4 x 1/7
2. 12 x 2 5/6
procedure
1. The answer is 4 x 1/7 is less than 4
2. The answer is 12 x 2 5/6 is greater than 12
