Answer:
2kx+4y=20 ⇒ kx+2y=10
3x+6y=30 ⇒ x+2y= 10
k is the coefficient of x, so it is the slope of the line
- when k=1, both equations will be same, then there are many solutions
- when k=0 there is one solution
- when k is anything different, then the lines will be parallel, so no solutions
Answer:
<h3>-16</h3>
Step-by-step explanation:
PEMDAS- (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) from left to right.
BOMDAS- (Brackets, Of, Multiply, Divide, Add, and Subtract) from left to right.
(-8)2
-8*2 (First, remove parenthesis.)
-8*2=-16
-16
Therefore, the final answer is -16.

Answer:
1 3/4 miles in 1/4 hour.
Step-by-step explanation:
Write and solve an equation of ratios:
x (1/4) hr
--------- = ------------
14 mi 2 hr
Cross multiplying, we get 2x = (1/4)(14), or
x = (1/4)(7), or x = 7/4
Steve can jog 7/4 miles in 1/4 hour. That's 1 3/4 miles in 1/4 hour.
