No. 1/2 equals 5/10, so 3/10 is actually less than 5/10.
We have been given a system of equations.
and
. We are asked to find the solution of the equation
by sketching the functions.
We can see that f(x) is a linear function in slope-intercept form. The slope of f(x) is 1 and y-intercept at point
.
We can also see that g(x) is a quadratic function. The function g(x) is an upward opening parabola, whose vertex is at point
.
Upon graphing both equations, we will get our required graph as shown in the attachment.
The solution of
will be the x-coordinates of points, where both functions will intersect.
We can see that both functions are intersecting at
, therefore,
are the solutions of
and option B is the correct choice.
3a³ + 2b³ = ?
Substitute for values:
3a³ + 2b³
a = 3
3 × 3³ + 2b³
b = 2
3a³ + 2 × 2³
Full question:
3 × 3³ + 2 × 2³
