When making two logarithms one logarithm you keep the base (in this case that would be 2) and multiply the two numbers (in this case 7 times 6 = 42) so the answer is
log(2) 42
Answer:
d = 6
Step-by-step explanation:
Given the coordinates A(4, 6) and B(d, 12) with the gradient of AB to be 3
Gradient m = y2-y1/x2-x1
Substitute the given values
3 = 12-6/d-4
3 = 6/d-4
Cross multiply
3(d-4) = 6
Expand
3d - 3(4) = 6
3d - 12 = 6
Add 12 to both sides
3d - 12 + 12 = 6 + 12
3d = 18
Divide both sides by 3
3d/3 = 18/3
d = 6
Hence the value of d is 6
Answer:
Step-by-step explanation:
erasers=e
pencils=p
3e+5p=7.55 ...(1)
6e+12p=17.40
divide by 2
3e+6p=8.70 ...(2)
(2)-(1) gives
p=8.70-7.55=1.15
from (1)
3e+5(1.15)=7.55
3e+5.75=7.55
3e=7.55-5.75
3e=1.80
e=1.80/3=0.60
cost of 1 eraser=$0.60
cost of 1 pencil =$1.15
