Answer:
y = -1/2 (4 x + 2)
Step-by-step explanation:
A system of two equations with no solution will consist of equations for <em>parallel lines</em>. The line will be parallel if they have the same slope (x-coefficient) and different y-intercepts.
The given line has a slope of -2, so eliminating the last two choices.
The first two choices can be expanded to slope-intercept form:
y = negative 2 (x minus one-half) ⇒ y = -2x +1 . . . same as given line
y = negative one-half (4 x + 2) ⇒ y = -2x -1 . . . parallel line
There will be no solution if another equation is ...
y = -1/2(4x +2)
Answer:
Step-by-step explanation:
The slope of g(x) is 5 because the slope of h(x) is 5 and g is parallel to h.
In point-slope form:
Rearranging for slope intercept form:
Answer:
B The cost, in dollars, for each additional gigabyte used.
Step-by-step explanation:
C = 59 + 15(g − 5)
when g=5, C=59 where it is the monthly cost
when g=6, c=59 +15, interpret that each additional gigabyte used will increase the cost for 15
Answer:
The domain of exponential functions is all real numbers. The range is all real numbers greater than zero. The line y = 0 is a horizontal asymptote for all exponential functions. When a > 1: as x increases, the exponential function increases, and as x decreases, the function decreases.
