If _____, use threshold braking any time you need to brake hard.
Inessa [10]

Answer:

The correct option is;

A. You don't have ABS

Step-by-step explanation:

A car braking system works by the friction action the break pad applies on the wheels, when the break is applied with much force, due to hard and sudden breaking of the motion of the vehicle, the break pad stops the rotation of the wheels but the vehicle could however continue skidding due to the high initial momentum

The being skidding vehicle in a situation of kidding increases the likelihood for an accident as the the vehicle can no longer be controlled at the steering either

Threshold braking is the technique of bringing the vehicle to a stop or slowing down in the shortest time possible by applying an optimum breaking force during breaking

Anti-lock Braking System is a safety feature that prevents skidding by keeping the wheels of the vehicle or aircraft from locking when excessive break is applied such that traction maintained between the wheels and the road.

Which equation or function is linear?
zepelin [54]

9514 1404 393

Answer:

  C.  2y = (2x-1)/4

Step-by-step explanation:

An equation is linear when the exponents of the variables are 1 and the sum of the exponents of the variables in any term is 1.

a) 3xy = 4 . . . . sum of exponents is 1+1=2

b) f(x) = 2/3(1 -x^2) . . . . exponent is 2

c) 2y = (2x -1)/4 . . . . all exponents are 1 (linear)

d) y = 3/(x+1)  ⇒  xy +y = 3 . . . . sum of exponents is 1+1 = 2

Jose bought 3 pens and 6 pencils for $6.60. Amy bought 5 pens and 8 pencils for $10.00. How much does one pencil cost?
xenn [34]

Answer:

pen = $1.20,  pencil = $0.50

Step-by-step explanation:

let x = pen

let y = pencil

create system of equations:

3x + 6y = 6.60        [can be simplified to be x + 2y = 2.20]

5x + 8y = 10.00

substitution method:

x = 2.2 - 2y

5(2.2 - 2y) + 8y = 10

11 - 10y + 8y = 10

-2y = -1

y = 1/2

solve for 'x':

3x + 6(1/2) = 6.6

3x + 3 = 6.6

3x = 3.6

x = 1.2
