Answer:10000
Step-by-step explanation:
Remember that log x and 10^x are inverse functions.
If you have log x = 4 and want the value of x, write this out:
log x 4
10 = 10
This simplifies to:
x = 10^4, and so the fourth answer choice is the correct one.
The shortest value has to be greater than 6 and less than 22 in order for 22 to be one of the 2 longer sides.
X2+5x-150= <span><span> x = 10 </span><span> x = -15
</span></span>
If 30% were perfect, 70% were not perfect. So we know that 70% of the total number of photographs is 210.
p(70/100)=210 multiply both sides by 100
70p=21000 divide both sides by 70
p=300
So there are 300 photographs in all.
Answer:
(x + 12) / 4
Explanation:
This was the way I was taught, hopefully it helps you.
y = 4x - 12
x = 4y - 12
x + 12 = 4y
(x + 12) / 4 = y
