Answer:
3
Step-by-step explanation:
We can find the slope of the given line in this two way:
1) the faster is calculate -a/b where a is the number the multiply x and b is the number the multiply y. In this case we have -1/3
2) the second method is rewrite the equation in slope intercept form and find the therm that multiply x
3y = -x-15
y = -1/3x - 5
Also in this case we have -1/3
Two perpendicular lines have the the product of the their slope that is -1
So the slope that we are finding is 3
In fact = 3 x -1/3 = -1
Answer:
acute
Step-by-step explanation:
Here are some helpful rules that will help you out in the future with these questions.
If...
a^2 + b^2 = c^2 its a right triangle
a^2 + b^2 < c^2 its obtuse
a^2 + b^2 > c^2 its acute
so...
Since 6+8>10
its acute
A number line is a line that extends infinitely in both directions (marked by arrows) that shows a range of numbers with a consistent distance between increments.
- Draw a line
- Draw arrows on both sides pointing out
- Write the minimum and maximum values on the left and right side repectively
- Add appropriate increments with equal distances on the number line
Answer:
Step-by-step explanation
The standard equation of a circle centered at origin is 
r = radius of the circle
The circle is passing through the point (0,5)
∴ radius 
∴ The equation of the circle is
