Answer: 
Step-by-step explanation:
Logarithms are in the format 
while exponential form is in the format 
So we can transfer a,b, and c from the log form to the exponential form
Answer:
x=90 y=45
Step-by-step explanation:
Answer is C
y and 45 are vertical angles
x=90 (right angle)
i need a graph so i can see then i will solve it
Answer:
-8
Step-by-step explanation:
m= y₂- y₁/ x₂-x₁
m= 1-9/7-6
m= -8/1
m= -8
Answer:
$11,714
Step-by-step explanation:
C(x) = 0.7x² - 462x + 87,944
this is a quadratic equation that opens up
the vertex will be the minimum
From the quadratic formula the x coordinate of the vertex is
x = -b/2a
x = 462/(2 * 0.7)
x = 330
Plug in
c(330) = 0.7(330²) - 462(330) + 87,944
c(330) = 11,714
$11,714
