Answer:
Therefore the two values required are 2.08 and -11.08.
Step-by-step explanation:
i) f(x) =
+ 10x - 12 is a quadratic equation and a quadratic equation will have two roots whose values when substituted in to the given quadratic equation will give the value.
ii) The question is therefore essentially asking us to find the roots of the given quadratic equation.
This can be done by equating the given quadratic equation to zero and then solving the equation for its roots.
∴
+ 10x -12 = 0 ⇒ x = (-10 ±
) ÷ 2
= (-10 ± 12.166)÷2 = 2.08, -11.08
Therefore the two values required are 2.08 and -11.08
Answer:
8
Step-by-step explanation:
2+2+2+2=8
2*4=8
Answer:
The slope is 2 and the y intercept is (0, -4)
Step-by-step explanation:
Put the line in slope intercept form, y = mx + b, where m is the slope and b is the y intercept.
4x - 2y = 8
Subtract 4x from both sides
4x - 2y = 8
-2y = -4x + 8
Divide each side by -2
y = 2x - 4
So, the equation in slope intercept form is y = 2x - 4.
The slope is 2 and the y intercept is (0, -4)
Answer:
We must order these decimals from least to greatest. Then we must determine how the least compares with the winning score.
9.80 -> 3
9.75 -> 1
9.79 -> 2
9.81 -> 4
The least decimal is 9.75. Now we must determine how 9.75 compare with the winning score.
The last swimmer must get a score less than 9.75 seconds in order to win.
