The x-intercept is a point on the x-axis.
y=0 at every point on the x-axis.
-2x + 1/2(0) = 18
-2x = 18
Divide each side by -2 : x = -9
Answer: 3
Step-by-step explanation:
Move the decimal back to its point of origin
Answer:
Depending of the exact career but measurements are plentiful in the healthcare business.
First, you'll most likely deal with weight and height... since that's part of most health care consultations.
Then, if you deal with medication, you'll use grams, milligrams, milliliters, liters all the time. depending if the medication is in solid or liquid form.
Even as a nutritionist, you'll deal with grams and such for portion sizes.
There are countless of ways you'll use maths and measurements in the healthcare sector.
2(5x + 2)^2 = 48
divide both sides by 2
(5x + 2)^2 = 24
square root both sides to clear the power of two.
5x + 2 = + - sqrt24
subtract 2 from both sides
5x = -2 + - sqrt 24
divide both sides by 5
x = (-2 +-sqrt24)/5 or decimal answers .58 and -1.38
