Answer:
y=1/2x
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Verify each case
The first step to solving a system of equations using substitution is to substitute an equation equal to one variable in for that variable in the other equation.
2x+3(x+1.5)=12
Answer:
Step-by-step explanation:
Multiplying two algebraic fractions produces a new algebraic fraction. Multiply the two numerators to get the new numerator and multiply the two denominators to get the new denominator. Then simplify by reducing the new fraction to lowest terms.
for example:
×
= 
Division of algebraic fractions
The procedure for dividing algebraic fractions is the same as the procedure for dividing common fractions. Replace the division by a fraction by the multiplication by the reciprocal of that fraction, like this. Then carry out the multiplication of the two fractions as described above.
for example:
can be written as
×
=

Answer:
option 3
Step-by-step explanation:
the ray is an angle bisector and divides the opposite side into segments that are proportional to the other two sides , that is
= 
( cross- multiply )
4x = 5(12 - x)
4x = 60 - 5x ( add 5x to both sides )
9x = 60 ( divide both sides by 9 )
x = 
None of the choices are the value of x
Answer:
y = 3x - 10
Step-by-step explanation:
I'm assuming that you are supposed to write the equation of a line that is parallel to the one given, going through the point given. I'm going with that. This is a line in slope-intercept form: y = mx + b.
If 2 lines are parallel to one another, the m values are exactly the same. So what we need to do is find the y-intercept value, b, since that is what is different in parallel lines. We will use the m value of 3, the x value from our point of 2, and the y value from our point of -4 to solve for b:
-4 = 3(2) + b and
-4 = 6 + b so
b = -10. Now we fit that back into the equation using the same m value as in the line it is parallel to:
y = 3x - 10
