Answer:

The vertical line test is a way to determine if a relation is a function. This test determines if one input has exactly one output on the graph. If any vertical line passes through more than one point on the graph, then the relation is not a function because two different outputs have the same input

Which answer shows this equation in standard form? 7 – 3(x – y) = –5x + 2 A.–8x + 3y = –5 B.–2x – 3y = 5 C. 2x + 3y = –5 D. 2x –
Effectus [21]
<span>The question is which answer does show the standard form of the equation: 7-3(x-y)=-5x+2. To see that let's transform our equation into standard form. Standard form of a linear equation is: ax+by=c. So our equation is: 7-3x+3y=-5x+2. Now we put the unknowns on the left and the numbers on the right: -3x+5x+3y=2-7 and we get 2x+3y=-5. And we see that the correct answer is C. </span>

Please show me the step on how to do this. I know the answer but how do you get it.

So, to find the volume of just the cement part, you need to find the volume of the whole shape, then find the volume of the garden. then subtract them to find the volume of just the cement sidewalk.

volume of garden: 16 x 6 x 1  (l x w x h)= 96 ft3

volume of whole:  length=16+4+4=24, width=6+4+4=14, height=1
you have to add 4 to each sides of the length and width to get the entire length.
 volume of whole=24 x 14 x 1=336 ft3

now subt.

336-90=246 ft3 would be the volume of the cement walkway.
