A) The solution is the point where the lines intersect: (5, 2.5)
b) The horizontal line has equation
.. y = 2.5
The downward-sloping line can be written in intercept form as
.. x/10 +y/5 = 1
or in standard form as
.. x +2y = 10 . . . . . . . . . (multiply the above equation by 10)
Answer:
D -55
Step-by-step explanation:
-55, since we put -1 and -3 instead of x and y. We multiply the result in the brackets by five. This gives us five
If the number is taken as x,
15x - 8
Answer: f(2) = 6
Step-by-step explanation: In this problem, we are given the function
f (x) = (x + 1) 2 and we are asked to find f(2). In other words, if we put an "x" into our function, we get a (x + 1) 2 out.
f we put a 2 into the function, we get f(2) = (2 + 1) 2 out. Now all we have to do is simplify on the right side.
2 + 1 gives us 3 and if we multiply 3 by 2, we get a product of 6.
Therefore, f(2) is 6.
