Answer:
D. 5
Step-by-step explanation:
You can use proportions to solve this.
36/45=20/5x
Cross multiply the 5x and 36 as well as the 45 and 20
180x=900
Then, divide the 900 by 180

Answer:
Step-by-step explanation:
Slope is negative reciprocal when two lines are perpendicular
m1=1/2 therefore m2=-2
The equation of the line in point-slope form is given as
Here m=-2 and (x1, y1)=(-3, -1)
Therefore,
The correct answer is:
there must be at least two lines on any plane because a plane is defined by 3 non-collinear points.
Explanation:
Since a plane is defined by 3 non-collinear points, we could have: a line and a point not on that line; two intersecting lines; two parallel lines; or simply 3 non-collinear points.
For 3 non-collinear points: If none of the 3 points are collinear, then we could have 3 lines, 1 going through each point. These lines may or may not intersect. If two of the 3 points are collinear, then we have a line through those 2 points as well as a line through the 3rd point.. Again, these lines may intersect, or they may be parallel.
Answer:
If we are solving for x it has<u> two answers</u> <u> 15,-1</u>
EXPLANATION:
first i take the root of both sides and then solve from there :
Step 1: Simplify both sides of the equation.
x2−14x+22=37
Step 2: Subtract 37 from both sides.
x2−14x+22−37=37−37
x2−14x−15=0
Step 3: Factor left side of equation.
(x+1)(x−15)=0
Step 4: Set factors equal to 0.
x+1=0 or x−15=0
x=−1 or x=15
HOPE THIS HELPS
x=−1 or x=15
Slope = y2-y1 / x2-x1 = 48-12 / 32-34 = 36 / -2 = -18 answer
