Here’s also s tip next tip if you google rounding calculator it will round it for you but the answer is 1
(-5x+7y=11) - (-5x+3y=19) =
4y = -8. (divide both sides by 4)
y = -2
Substitute
-5x + 7(-2) =11
-5x - 14 =11
-5x = 25
x = -5
y = -2 and x = -5
Answer:
.2625
Step-by-step explanation:
logb(3) = 0.5646, logb(4) = 0.7124, and logb(5) = 0.8271
logb(5/3)
We know that logx ( y/z) = logx (y) - logz (z)
logb ( 5) - logb(3)
0.8271 - 0.5646
.2625
