Without solving them, say whether these equations have a positive solution, a negative solution,
a zero solution, or no solution.
Positive solution= the answer is a positive number.
Negative solution= the answer is a negative number.
Zero solution= the answer is zero.
Negative solution= the variable goes away, so you can't solve it!
a. 3x=5
b. 5z+7=3
c. 7-5w=3
d. 4a=9
e. y=y+1

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

answer: sine

step-by-step explanation:

i think the correct option is the second option.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
