Answer:
y=-9
Step-by-step explanation:
If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22
We can solve for multiplication first:
4-2y=22
Then we can subtract four on both sides, canceling out the four on the left side:
-2y=18
Now to isolate y, we divide both sides by -2, resulting in the solution:
y=-9
Hope this helps!
Answer: here
Step-by-step explanation:
Acute Angle - An angle less than 90 degrees. Right Angle - An angle that is exactly 90 degrees. Obtuse Angle - An angle more than 90 degrees and less than 180 degrees. Straight Angle - An angle that is exactly 180 degrees. Reflex Angle - An angle greater than 180 degrees and less than 360 degrees.
Answer:
Step-by-step explanation:
y = 4x + 1
Slope of line = 4
Slope of perpendicular to line = -¼
Point-slope equation for line of slope -¼ that passes through (12, -7):
y+7= -¼(x-12)
Let mass of truck be t
mass of car A be a
and carB be b
so , a=2b-5
t=a+2135
putting a into t...
t=2b-5+2135
so, a+b+t=11350 ( putting all values)
2b-5+b+2b-5+2135=11350
so b=1845
a=3685
t=5820
so weight of Car A is 3685 lb
weight of Car B is 1845 lb
and truck is 5820 lb ......answers !!
