Answer:
If the equation log(6x+10)=log(1/2) x is solved by graphing, the curves intersect at approximately x=0.46
Step-by-step explanation:
Equation
log(6x+10)=log(1/2) x
We must graph two functions:
f(x)=log(6x+10) and
g(x)=log(1/2) x→g(x)=log0.5 x
If we graph these two equation the point of intersection is approximately (0.464, 1.107)=(x,y)
x=0.464→x=0.46
y=1.107→y=1.11

Answer:
Dan would be left over with $43 a week.
Step-by-step explanation:
= 40%
= 50%
Rent: $430 - 40% = $172
Food: $430 - 50% = $215
$215 + $172 = $387
$430 - $387 = $43
Answer:
Step-by-step explanation:
Slope intercept form of a line is given by:
Where
m is the slope and b is the y-intercept
Given slope is
We can write:
Now to find b, we replace x with -3 and y with -4, given, so we have:
So, the equation is:
Now,
The standard form is given by:
So, we take x and y to left side and the constant to right side. Rearranging, we get:
The first answer choice is right.
