Answer:
x=1000
Step-by-step explanation:
log x = 3
log10 ( x) = 3
Raise each side to the power of 10
10^( log10 ( x)) =10 ^3
x = 10 ^3
x = 1000
Answer:
<em>x = 2</em>
Step-by-step explanation:
We are given the equation 3 - 4x - 2 = 2x - 11;
If you want this explanation in a " statement reasoning " format refer to the attachment below;
The 2 equations are
18.20x+19.50y=230.10
and
x+y=12
where x is the months of original cost and y is months for new cost. Since you know that you paid for one year (12 months) you can make the second equation. Then you want to substitute the first equations x by making the second equation
x=(12-y)
18.20(12-y)+19.50y=230.10
218.40-18.20y+19.50y=230.10
1.30y=11.70
y=9
so that means you had the original rate for 3 months and the new one for 9 months
Hey there!
B in a slope intercept form equation is the the y intercept. It dictates where the line will cross the y axis, and therefore the line's placement altogether. This is because if there was no y intercept, the line would only be shaped by the slope, and would start at 0.
Hope this helped!
In a graph, it is when two variables move in an upwards direction.
