Answer:
20
Step-by-step explanation:
You have to divide to find the answer so
4/1 * 5/1
Which will get you to 20.
19. Answer: 3p^6
Working:
3p^4 x p^2 = 3p^6
(Formula: a^b x a^c = a^b+c)
20.Answer: 42z^8
7z^5 x 6z^3 = 42z^8
(Same formula as Q19)
7. Answer: a^-4 or 1/a^4
a^3 / a^7 = a^-4
(Formula: a^b / a^c = a^b-c)
8. Answer: j^-1 or 1/j
(Same as Q7)
9. Answer: 1
(Same as Q7)
(x^0 = 1)
10. Answer: k^-4
(Same as Q7)
11. Answer: 3x^3/4
(Same as Q7)
(9/12 = 3/4)
12. Answer: 2f^5
13. Answer: (y^8)/2
(Same as Q7)
(4 - (-4)) = (4 + 4)
14. Answer: 1/n^5
(negative power = 1/power)
Sorry got no more time sorry
Answer: Negative
If the same negative number is multiplied to each side of a true inequality, then the inequality sign flips to make the new inequality true as well
Example:
Take 1 < 5 and multiply both sides by -2 and we get -2 > -10. The "less than" sign flips to "greater than" since -2 < -10 is false. The value of -10 is further to the left of -2 so -10 is smaller in value. The negative basically takes the complete opposite which is why the flip must happen.
This sign flip rule does not happen if you multiply both sides by a positive number.
Answer:
(x-5)(x+9) = 0
Step-by-step explanation:
In the equation above, if you plugged in the values given(5, and -9) then you will see that the answer i s0. You basically takes the zeroes you are given, and invert their signs to form the equation.
