Answer:
16
Step-by-step explanation:
6x+3y=15
-6x. + -6x
3y=-6x+15
÷3 ÷3 ÷3
y=-2x+5
m=-2/1
b=5
Answer:
yeah you're right
Step-by-step explanation:
The correct answer to the physics problem in pressure given above would be 1.5 N.
First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).
Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)
Consequently, I used the equation of pressure (P = Force/Area).
P = 461.58 N / .00314 m^2
P = 1.47 or 1.5 N
Answer:
k(- 7) = - 89
Step-by-step explanation:
To evaluate k(- 7), substitute t = - 7 into k(t), that is
k(- 7) = 10(- 7) - 19 = - 70 - 19 = - 89
