The answer is :
<span>A. Always

<span>If
two equations have different slopes but equivalent y-intercepts, they
will have one solution and that will be the point where the y-intercept
is. If two equations have different slopes and different y-intercepts,
then there will be one solution where those two lines meet. If two
equations have the same slope but different y-intercepts, the lines will
be parallel, and there is no possible intersection point. And if two
equations have equal slopes and equal y-intercepts, these lines will
have an infinite amount of solutions, because if the equations are one
the same line, every single point on that line is a solution to the
system. </span>
Answer:
35 grams
Step-by-step explanation:
The ratio of zinc to copper is 3 to 11
A jar of chemical contains 385 grams if copper
Therefore the number of grams of zinc it contains can be calculated as follows
3/11= x/385
11x= 385
x= 385/11
= 35 grams
Hence the chemical contains 35 grams of zinc

Answer:4x+30
Step-by-step explanation:
Distribute 4(5+x) to get 20+4x
So then 10+20+4x
Which is 4x+30
