Answer:
y = -2/3x + 4
Step-by-step explanation:
first we take the original equation and convert it to y=mx+b (a form we know how to graph)
that gives us y = 3/2x + 2
(Here's my work for that):
6y - 9x = 12; add 9x on both sides
6y = 9x + 12; divide 6 on both sides
y = 9/6x + 12/6
y = 3/2x + 2
next to make a line *perpendicular* to this, we make the slope negative and swap the fraction (-2/3)
then we just uh graph that slope and try to find the y intercept. i did it already and i got 4
0.7 is the answer i learned dis 4 yrs ago
<u>Solution-</u>
If the lines are parallel, then the alternate interior angles are congruent.
As the sum of measures of the two alternate interior angles = 210°
⇒ Measure of one alternate interior angles = 105°
Since a straight angle contains 180º, the two angles forming a linear pair also contain 180º when their measures are added (making them supplementary).
Answer:
the total is 80 cm^2
Step-by-step explanation:
just because you should multiply by 2 40*2=80 cm^2
i hope this helps
have a great day
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
