0.75 is the answer because 14/20 would be .7 would equal 0.70
f(x) = (x – 7)(x – 5)(x – 5)(x + 2) should be your answer
To get the x, -2, 7, 5 and 5, you must first place each parenthesis = to zero. Solve for x.
x - 7 = 0, x - 7 (+7) = 0 (+7), x = 7
x - 5 = 0, x - 5 (+5) = 0 (+5), x = 5
x - 5 = 0, x - 5 (+5) = 0 (+5), x = 5
x + 2 = 0, x + 2 (-2) = 0 (-2), x = -2
hope this helps
Answer:
two real, unequal roots
Step-by-step explanation:
This is a quadratic equation. The quadratic formula can be used to determine how many and what kind of roots may exist:
Find the discriminant, which is defined as b^2 - 4ac, if ax^2 + bx + c = 0. In this case, a = 1, b = -2 and c = -8, so that the discriminant value is
(-2)^2 - 4(1)(-8), or 4 + 32 = 36.
Because the discriminant is real and positive, we know for certain that we have two real, unequal roots
Answer:
A. Subtraction Property of Equality
Step-by-step explanation:
3x + 4 = 10
Subtract 4 from both sides ---->Subtraction Property of Equality
3x + 4 - 4 = 10 - 4
3x = 6
So
If 3x + 4 = 10, then 3x = 6
