Answer:
y=-5x-21
Step-by-step explanation:
So the slope will be the same, rewrite the equation with the same slope and substitute in the coordinates. Then, solve for b.
y=mx+b
-1=-5(-4)+b
-1=20+b Subtract 20 from each side
-21=b
The equation is y=-5x-21
Answer:
C 109
Step-by-step explanation:
First add all the known angles inside the triangle first to get 109°
Then since all angles in a triangle add to 180°
you take away 109 from 180 so
180-109 which equals 71
Then since all angles on a straight line add up to 180°
you take 71 from 180 so
180-71 = 109
so x = 109°
Answer:
x = 22°
y = 26°
z = 48°
Step-by-step explanation:
∠PQS and ∠QSR is a pair of alternate interior angles
plus PQ is parallel to SR
then
x = 22°
SPR is an isosceles triangle then m∠PRS = 66°
Therefore x + y = 180-(66+66) = 180-132 = 48
then y = 48 - x = 48-22 = 26
finally, z = x + y = 48
6/9, 4/6 just multiply the top and bottom by the same number to find the equivalent fraction
Answer:
143
Step-by-step explanation:
x2 + 12x + 6 + 3x + 1
substitute
(8)2+12(8)+6 +3(8) +1
distrubute
16+96+6+24+1
add like terms
