This is last question i need to finish what are the possible rational zeros of f(x) = 2x3 − 15x2 + 9x + 22? ± 1, ± 2 ± 1, ± 2, ± 11, ± 22 ± 1, ± 1 over 2, ± 2, ± 11 over 2, ± 11, ± 22 ± 1, ± 1 over 2, ± 1 over 11, ± 1 over 22, ± 2, ± 2 over 11

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
