4x + 7y = 1 ⇒ 12x + 21y = 3
3x + 10y = 15 ⇒ <u>12x + 40y = 60</u>
<u>-19y</u> = <u>-57</u>
-19 -19
y = 3
4x + 7(3) = 1
4x + 21 = 1
<u> - 21 - 21</u>
<u>4x</u> = <u>-20</u>
4 4
x = -5
(x, y) = (-5, 3)
Answer:Write in slope-intercept form, y=mx+b
.
y=4x+43
hope this helps
WELL, THIS IT HOW I GOT Y = 14
50 = 2X
25=X
then ; 50 + 2(25) + (5y+10) = 180
50 + 50 + 5y+10 =180
110 + 5y =180
5y = 180 -110
5y = 70
y = 14
HOPE THIS HELP ,IF ITS RIGHT. lol
Answer:
b < 5
Step-by-step explanation:
-2+b<3
Add 2 to each side
-2+2+b<3+2
b < 5
Answer:
N s or Kg m/s
Step-by-step explanation:
Impulse is the product of the force and time or mass and velocity.
Impulse = force x time
, or
Impulse = mass x velocity
Therefore; the SI units of impulse is newton-second (N · s). Reduced to base units in the International System of Units ( SI ), a newton-second is the equivalent of a kilogram-meter per second (kg · m/s).
