Answer:
4/10
Step-by-step explanation:
0.4 is said by "four-tenths." Fractions are also said the same way. Notice how there is a four and a ten. This should be easier to help you make decimals in fraction form. The four would be the numerator and the ten would be the denominator, making the final answer 4/10.
The graph C shows a function
The other options all have an x-value that has two y-values.
Functions need unique mappings from every point in the domain.
Well first, you have to get both equations to the y= form
y=mx+b
X=-5-y add y to x
y+x=-5 then subtract x
y=-x-5 is your equation
_____________________
for the second one:
2+y=-x+3 subtract 2
y=-x+1 is your equation
__________________________
Take both equations and compare:
Both the slopes are the same of -x, so that means the will lines never touch (also because of different y intercept)
So, the answer is parallel.
