Answer:
499.20
Step-by-step explanation:
3000
x.08. Interest rate
= 240 interest after one year
+. 3000
=3,240 principal plus interest after one year
x. .08
259.20. Interest in year two
+ 240.00 interest in year one
= 499.20. Interest earned in 2 years
Answer:
y=-2x
This type of equation is a form of a direct proportion.
Answer:
6
Step-by-step explanation:
1. re-write the given system:
cx+3y=c-3; => y= -cx/3 +(c-3)/3
12x+cy=c; => y= -12x/c+c/12
2. according the condition the rule for the parallel graphs is:
-c/3= -12/c
3. to calculate the unknown 'c':
c²=36; ⇔c=±6
Answer:
y(-4) = 5
y'(-4) = -7
Step-by-step explanation:
Hi!
Since the tangent line T and the curve y must coincide at x=-4
y(-4) = T(-4) = 5
On the other hand, the derivative of the curve evaluated at -4 y'(x=-4) must be the slope of the tangent line. Which inspecting the tangent line T(x) is -7
That is:
y'(-4) = -7
