In order to get h alone, you must eliminate the 40. So to do this, you must subtract the 40 (as you always do the opposite operation, and if there isn't one, it is always positive), and this becomes 55h=150.
To find out what h is, you then divide both sides by 55. 55h/55=h
150/55= 2.727
Therefore, h=2.727
HOpe this helps :)
Answer:
c=5
Step-by-step explanation:
3c-3(6-2c)=27
3c-18+6c=27
9c=45
c=5
Based on the model, 28.6 is the estimated increase, in inches, of a boy’s height each year.
Answer:
y- intercept --> Location on graph where input is zero
f(x) < 0 --> Intervals of the domain where the graph is below the x-axis
x- intercept --> Location on graph where output is zero
f(x) > 0 --> Intervals of the domain where the graph is above the x-axis
Step-by-step explanation:
Y-intercept: The y-intercept is equivalent to the point where x= 0. 'x' is the input variable in an equation, therefore the y-intercept is where the input, or x, is equal to 0.
f(x) <0: Notice the 'lesser than' sign. This means that the value of f(x), or 'y', is less than 0. This means that this area consists of intervals of the domain below the x-axis.
X-intercept: The x-intercept is the location of the graph where y= 0, or the output is equal to 0.
f(x) >0: In this, there is a 'greater than' sign. This means that f(x), or 'y', is greater than 0. Therefore, this consists of intervals of the domain above the x-axis.
You get 12.6
After the decimal starts the the tenth place. In order to round to the tenth place, we need to know the hundredth place which is the 7. If the hundredth place is 5 or greater then we round up and if it's 4 or lower then we keep the tenth place the same number as it is before.
Since the hundredth place is greater than or equal to 5, we round up the tenth place to 6. If you have any questions then leave a comment. Good luck!
