Answer:
12x^2-4
Step-by-step explanation:
Answer:
y = -2.5x + 5
Explanation:
Convert -5x - 2y = -10 into slope-intercept form: y = -2.5x + 5
You can start solving for and graphing points by putting numbers in for 'x' in the equation, and the answer you get out will be y.
Ex: -2.5(7) + 5 = -12.5
7 is the number we inserted for x, so it is the x value. -12.5 is the number we got out of the equation, so it is the y value.
The points will now look like this: (x, y) but for the example they would look like (7, -12.5)
Plot the numbers, x being on the horizontal axis, y being on the vertical axis.
Answer:
<em>The point lies barely outside of the circle</em>
Step-by-step explanation:
<u>Equation of a Circle</u>
Given its center (h,k) and radius r, the equation of a circle is given by
The circle given in the question is centered at (7,8) and has a radius of 6, thus its equation is
To find out if a point (a,b) is outside or inside the circle area, the following conditions apply.
if 
then the point lies outside of the circle area
if 
then the point lies inside of the circle area
Let's use the point as given (6,2)
Thus the point lies barely outside of the circle
Olivia applied the scale factor to the measurements of the model she saw. We need to know those in order to calculate the new ones.
Answer:
15
Step-by-step explanation:
900 light bulbs per hour
60 minutes per hour
X lightbulbs per minute
Divide 900 lightbulbs by 60 minutes
15
The rate is 15 light bulbs per minute
