Answer:
f(2)= -4
Step-by-step explanation:
f(x)= -x^3 + 6x - 7
f(2) = -2^3 + 6*2 - 7
f(2)= -8 +12 -7
f(2)= 3-7
f(2)= -4
Answer:
x = 11/3 = 3 2/3
y = 13/3 = 4 1/3
Step-by-step explanation:
Here, we want to solve the system of equations simultaneously
x + y = 8
2x -3 = y
From the second equation, we have an equation for y
we can simply proceed to substitute this into the first equation
x + 2x - 3 = 8
3x - 3 = 8
3x = 8 + 3
3x = 11
x = 11/3
Recall;
y = 2x - 3
y = 2(11/3) - 3
y = 22/3 - 3
y = (22-3(3))/3
y = (22-9)/3 = 13/3
The answer is c because it makes the most sense
