Answer: 480 milligrams
Step-by-step explanation:
We can solve this by using direct proportion whereby y = kx
where,
x = patient's weight = 92 pounds
k = constant
y = milligrams of antibiotics = 320
Using y = kx
320 = 92k
k = 320/92
k = 3.4782609
The antibiotic that should be given to a patient who weighs 138 pounds will be:
y = kx
y = 3.4782609 × 138
y = 480 milligrams
The antibiotic that should be given to a patient who weighs 138 pounds is 480 milligrams.
Answer:
The equation of line having slope m and y-intercept b is
y = m x + b
The other two equations of line in the same family having intercepts p and q are,keeping the slope same i.e m , described in the question are
→ y= m x + p
→ y = m x + q
As both the equation have same slope i.e m , so lines will be parallel, but their Y - intercept are different i.e distance from the origin where it cuts the y-axis are different i.e at a distance of p and q from origin.
