Answer:
c=18
Step-by-step explanation:
<em>To solve for c you need to do cross product property</em>
You have to multiply diagonally
So 3*30= 90
5*c= 5c
90= 5c
Now its a one step equation
Divide 90 by 5 =18
c= 18
Answer:
Step-by-step explanation:
Answer:
neither
Step-by-step explanation:
parallel lines have the same slope and different y-intercept
perpendicular lines have the reciprocal as slopes( 2/5 and 5/2)
as these slopes have neither the answer in NEITHER
Answer:
$36
Step-by-step explanation:
we need to find the cost of 12 items, and the function of determining the cost is C(x)=2x+12, where x is the number of items (the input value of the function)
we know that there are 12 items, so in this function, x=12
substitute x as 12 in the function; the x in C(x) also gets substituted as 12, as 12 is the input value and the value of C(x) is the output
C(12)=2(12)+12
multiply
C(12)=24+12
add
C(12)=36
that means, for 12 items, the cost will be $36
