Answer:
4x
3x
Step-by-step explanation:
1.)
we see that when x=0 y=0 which means that our equation
y=mx+b
b=0
(this is shown if we plug in 0 for x)
0= 0x+b
0=b
Next, we notice that each time it's increasing by four which means our slope is just 4
the answer is 4x
The y intercept (or b) is the same deal as question one
we can also see that when x=1 y=3 which means that
3=x+0
3=x
our slope is 3
Answer:
x = 2.25 y = 0.75
Step-by-step explanation:
2x = 9.5- 5
2x = 4.5
x = 4.5 ÷ 2
x = 2.25
know we now what is x so in the second one we evaluate x
3(2.25) + 5y = 10.5
6.75 + 5y = 10.5
5y = 10.5- 6.75
5y = 3.75
y = 3.75 ÷ 5
y = 0.75
that's it !
if you want to check your answer you can evaluate x and y so it will be like
2×2.25 + 5
= 4.5 + 5 = 9.5
and
3× 2.25 +5×0.75
= 6.75 + 3.75 = 10.5
Answer:
were is the line graphed?
Step-by-step explanation:
But I will help?
As, v=√2as
Squaring both sides,
v²=2as
∴ s= v²/2a
