Answer:
Option C is correct.
System of equation which will produce infinitely many solutions:
3x - y = 14
-9x +3y = -42
Step-by-step explanation:
From the options
Only equation which is infinitely many solutions is
3x - y = 14 ......[1]
-9x +3y = -42 ......[2]
For infinitely many solutions, we are looking for linearly dependent equations, which means one equation is an exact multiple or sub-multiple of the other.
Multiply [1] by -3 we get
or
-9x + 3y = -42 which is same equation as [2]
therefore. by definition of infinitely many solution,
equation 2 is -3 times(or multiple) of equation 1
Answer:
th answer is 7:15 pm
Step-by-step explanation:
basically just count with your hands if you want, start with one finger and say 13 and go up from there, 7th finger is the 19th. Thats my easiest way of doing it. Or you can subtract 24-19 and subtract 12 from the remaining sum

Answer:
Step-by-step explanation:
Cross section is the isosceles trapezoid.
<u>Area of trapezoid:</u>
We have one of the bases and the height.
Let the difference of the base lengths is x.
<u>We have:</u>
- (x/2)/h = cot θ ⇒ x = 2h cot θ
<u>The area is:</u>
- A = 1/2(w + w + 2h cot θ)h = (w + h cotθ)h
