For a line in the form:
In this case, for the line 2x + 10y = 20 with a=2 and b=10 the slope is:
Now, two lines are perpendiculars if the slopes satisfy the following equation:
So, for the line we want the slope is:
Finally, the line pass througth the point (2, 3) with slope m=5, so the equation is:
The equation of the line is y = 5x - 7
The standard form of the equation of a circle with center (h, k) and radius r is
(x-h)² + (y-k)² = r²
You have a circle centered at (-3, 1) with radius 1, so the standard form equation is
(x+3)² + (y-1)² = 1
Answer: angle two us the same as angle 4,6,and 8
angle 1,3,5, and 7 are 70
Step-by-step explanation:
Answer:
$11.25
Step-by-step explanation:
When finding a discount that has a percentage, we have to multiply the amount of the specific item being discounted and the percentage of the discount. In this case, we have a forty-five dollar headset at a twenty-five percent discount rate. To find the price, multiply the amount of the headset by the percentage of the discount.
$45 * 25%
$11.25
Meaning that the price of the discount will be eleven dollars and twenty five cents.
