Answer:
Option B
y coordinate is 0
Step-by-step explanation:
We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.
X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0
To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.
Thus we have along x axis, y values to be 0
Hence any point on x coordinate will be of the form (a,0) where a can be any real number
So option B is right
15/6=2.5 which is the scale factor since they are similar triangles. We divide each side of the large triangle by 2.5 to get the sides for the small triangle since they are similar. 20/2.5=8cm
25/2.5=10cm
For the second problem, you put 15/6 and set in equal to x/8 when you cross multiply you get 6x=120 then you divide x=20
For the last problem, you divide 43,75 by 5 then multiply it by 400 to get the kiloliters which equals 3,500.
Dimensional Analysis is the way you want to go
Answer:
B
Step-by-step explanation:
y = 5x
check your work by plugging in the values
y = 5(1)
y = 5 yes
y = 5(2)
y = 10 yes
y = 5(3)
y = 15 yes
y = 5(4)
y = 20 yes
