Answer:
C(x) = dependent variable
x = independent variable
Step-by-step explanation:
A function means the dependent variable is determined by the independent variable(s).
In the given function, C(x) = 7.25x + 1,500:
The <em>x</em> represents the input value, which is the independent variable. The input value does not depend on other factors. The independent variable, x, can have different values. When x (input) changes, C(x) (output) also changes.
C(x) or y represents the output value, or the dependent variable. The output value, "C(x)," means that the output value <em><u>depends</u></em> on or is determined by the input value, x. For example, if your input value is 1, then:
C( 1 ) = 7.25( 1 ) + 1,500
C( 1 ) = 7.25 + 1,500
C( 1 ) = 1,507.25.
Answer:
x<10
Step-by-step explanation:
Add '-7' to each side of the equation.
7 + -7 + -0.3x = 4 + -7
Combine like terms: 7 + -7 = 0
0 + -0.3x = 4 + -7
-0.3x = 4 + -7
Combine like terms: 4 + -7 = -3
-0.3x = -3
Divide each side by '-0.3'.
x = 10
Simplifying
x = 10
Easy, just plug n chug
a=-2 b=3 and c=-1/3
-2^3=-8
-6(-1/3)=2
-8+2=-6
Thus, your answer is, 6.
The b was extra unnecessary information.
Answer:
x = 3
Step-by-step explanation:
using the tangent ratio in the right triangle and the exact value
tan30° = , then
tan30° = = = ( cross- multiply )
x = 3
