Finish solving for x and y.

Elodia [21]

Answer:

x=6

y=1

Step-by-step explanation:

3x=18, so when you divide 3x by 3 to get x alone, you also divide the other side and 18 divided by 3 is 6. now you know that x equals 6. then you plug x back into either equation to solve for y. I chose to plus into x-3y=3. it would read 6-3y=3. you then subtract 6 from both sides and get that -3y=-3. therefore when you divide both sides by -3, you get that y=1

An overhead garage door has two springs, one on each side of the door. A force of 15 pounds is required to stretch each spring 1

svlad2 [7]

Answer:

120 pounds

Step-by-step explanation:

Data provided in the question:

Force applied, F₁ = 15 pounds

Displacement by Force F₁, x₁ = 1 foot

At natural length of the spring total movement of the door = 8 feet

Now,

we know,

Force in spring, F = kx

where, k is the spring constant

Thus,

15 = k(1) ............(1)

now when the door travels half the distance x₂ = $\frac{8}{2}$ = 4 feet

Therefore,

F₂ = k(4) ..........(2)

Dividing 2 by 1

we get

$\frac{F_2}{F_1}=\frac{k(4)}{k(1)}$

$\frac{F_2}{15}=\frac{(4)}{(1)}$

F = 15 × 4 = 60 pounds

Thus,

for 2 springs combined force applied = 2 × 60 pounds = 120 pounds
