Answer:
(-5,2)
Step-by-step explanation:
Answer:
3600
Step-by-step explanation:
There's a 1 - 1 in the denominator so you can cancel those out. (1-1=0. that's why you can cancel it out)
You now have a value in the numerator and denominator that are the same so you can cancel those out as well which leaves you with 3600. (a number over itself equals to 1. any number multiplied by 1 is equal to itself. that's why you're allowed to cancel those out.)
Log (base8) 2 = 1/3
Log (base 8) (4x^2) + Log (base 8) 4 + 2Log (base 8) x = 2/3 + 2 Log (base 8) x
1/3 + 2/3 + 2 Log (base 8) x = 1
2 Log (base 8) x = 0
Log (base 8) x = 0
x = 8^0
x = 1.
Answer:
19) n = -14
20) x = 4
21) b= -14
22) x = 2
23) x = -1
24) x = -9
Step-by-step explanation:
19) Use the distributive property to get rid of the parentheses. You will get: 20-4n = 76. So, n = -14.
20) Multiply both sides of the equation by 2 to get: -8 + x = -4. So, x = 4
21) Add 3 to both sides to get: = -1. So, b = -14
22) Use the distributive property to get rid of the parentheses. You will get: -40 - 5x = -50. Then, add 40 to both sides to get: -5x = -10. So, x = 2.
23) Use the distributive property to get rid of the parentheses. You will get: -72 = -64 + 8x. Then, add 64 to both sides to get: -8 = 8x. So, x = -1
24) Add 2 to both sides to get: = -3. So, x = -9
Hope this helps :)
