2/3 x = 4/5
multiply both side by 3/2 it gets x alone
2/3 * 3/2 = 1
2/3 x * 3/2 = 4/5 * 3/2
x = 12/10
x =6/5
x = 1 1/5
Answer:
y= 5x......eqn(1)
-2x+2y= 12......eqn(2)
now
substituting value of eeqn(1) in eqn(2) ,
-2x+2(5x) =12
-2x + 10x = 12
8x = 12
X = 12 ÷ 8
X= 3/2
now put value of X in eqn (1)
y= 5x
y = 5 × 3/2
y = 15/2

Step-by-step explanation:
We are given the following information in the question:

where a > 0 and b > 0.


where v(t) is the required tumor volume as a function of time that has an initial tumor volume of V(0) = 1 cubic mm.
The piece-wise linear functions can be written as follows:

<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For x less than 5, the y-intercept is of b = 3 and the function also gos through (2,2), hence the slope is:
m = (2 - 3)/(2 - 0) = -0.5.
Hence the rule is:
.
When x = 5, the function is constant at -5, hence:

For x less than 5, the function goes through points (6,3) and (7,2), hence the slope is:
m = (2 - 3)/(7 - 6) = -1.
Then:
y = -x + b
When x = 6, y = 3, hence the y-intercept is given as follows:
3 = -6 + b
b = 9.
Hence the rule is:
.

, or 
<h3>
Explanation:</h3>
Use the Keep Change Flip method. Change the sign to multiplication and flip the second fraction. 
Multiply the numerators and the denominators separatley. 
This cannot be simplified further, but it can be converted to a mixed number (as opposed to an improper fraction).
