Answer:
x = 23.999996
Step-by-step explanation:
Let's solve your equation step-by-step.
64−x+52=128x
Solve Exponent.
64−x+52=128x
log(64−x+52)=log(128x)(Take log of both sides)
(−x+52)*(log(64))=x*(log(128))
−x+52=(
log(128)
log(64)
)*(x)
−x+52=1.166667*x
−x+52=1.166667x(Simplify both sides of the equation)
−x+52−1.166667x=1.166667x−1.166667x(Subtract 1.166667x from both sides)
−2.166667x+52=0
−2.166667x+52−52=0−52(Subtract 52 from both sides)
−2.166667x=−52
−2.166667x
−2.166667
=
−52
−2.166667
(Divide both sides by -2.166667)
x=23.999996
Sorry is this is wrong, did it in a hurry :(
N is the variable, you solve by subtracting 6 from 20, getting n = 14.
Answer:
true
Step-by-step explanation:
11a - 2a
Factor out a
a(11-2)
a *9
9a
Answer:
y = 15x + 65
Step-by-step explanation:
To find the equation, we can use two points in the graph to find the parameters 'a' and 'b' in the equation:
y = ax + b
For the value x = 1, we have y = 80
For the value x = 9, we have y = 200
So we have that:
80 = a*1 + b
200 = a*9 + b
Making the second equation minus the first one, we have:
8a = 120
a = 15
Now we can find 'b':
80 = 15 + b
b = 65
So the equation is y = 15x + 65
