Answer:
B. y = 1/3x
Step-by-step explanation:
The slope of the given line is -3, so the slope of the perpendicular line will be the negative reciprocal of that: -1/(-3) = 1/3. This eliminates choices A and C.
We can find the y-intercept (b) if we use the given point values in the equation ...
y = 1/3x +b
we get ...
-2 = (1/3)(-6) +b
-2 = -2 +b . . . simplify
0 = b . . . . . . . add 2
So, the equation of the perpendicular line through the given point is ...
y = 1/3x . . . . matches choice B
_____
<em>Alternate solution method</em>
You can try the given point in the given equations. You will find that only the equation of choice B will work.
The total amount of degrees in a triangle is 180. All three angles should add up to 180˚
We know that 40+60 = 100
The next step is to do 180-100 to get the other angle.
180-100 = 80
So the measure of the third angle is 80˚
Hope this helps!
(Also if you want to do this in one equation, you would do 40+60+x = 180
40+60+x = 180
100+x = 180 (combine like terms)
x = 80 (Subtract 100 from both sides)
Answer:
5
Step-by-step explanation:
0.5x=6-3.5
0.5x=2.5
x=2.5÷0.5
x=5
X and y are points that help u place other points
Answer:
Kayla = 0.4 inches
Miranda = 0.46 inches
Stefano = 0.5 inches
Kateira = 0.58 inches
Step-by-step explanation:
Kateira plant = 0.58 inches
Stefano plant = 1/2 inch
Change to decimal
Stefano plant = 0.5 inches
Kayla plant = 0.4 inches
Miranda plant = 5/11 inches
Change to decimal
Miranda plant = 0.46 inches
Order from least to greatest
= 0.4, 0.46, 0.5, 0.58 inches
That is, Kayla, Miranda, Stefano and Kateira respectively
