Direct variations take the form y=kx. We need to solve for y in order to find k.
<span>3x+5y=0 </span>
<span>5y=-3x </span>
<span>y=(-3/5)*x </span>
<span>k=-3/5.</span>
d=rt
distance car one = 58 time
distance car two = 63 time
you are being asked the distance between the two
d2- d1 = t(63-58) = 5t = 40
divide both side by 5 and your answer is 8 hours.
Answer:it's actually C. Both (1,3) and (-2,-4)
Step-by-step explanation:
To check whether (-2,-4) is a solution of the equation let's substitute x= -2 and y= -4 into the equation:
-7x+3y=2
-7*(-2)+3*(-4)=2
14-12=2
2=2
Do the same thing with (1,3)
-7x + 3y = 2
-7 * 1 + 3 * 3 = 2
-7 + 9 = 2
2 = 2
Answer:
15
Step-by-step explanation:
15 is half of 30, the output values are the input values divided by 2 :)
