Ihave 10 questions (sorry)
1. what is the value of w in the following proportion 3: 4 = w: 28
2. what percent of 300 is 120
3. what is 15% of 90
4. which is a representation of the number x is 25% of 70
5. what percent of 120 is 42
6. 25% of what number is 35
7. in the following proportion what dose x equal 4: 9=12: x
8. 40% of 240
9. 66% of what number is 33
10. 11% of what number is 22

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

about 168 miles

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
