The meaning of (f + g)(-1) is you substitute -1 to x of whatever polynomial you obtain after adding the polynomials f(x) and g(x).
f(x) + g(x) = -2x + 8 + 3x = x + 8
Substitute -1,
(f + g)(-1) = -1 + 8 = 7.
Thus, the answer is 7.
Let, the number of hour, she can still watch the T.V. = x
Equation would be: x + 1.5 ≥ 5
Solving the equation:
x + 1.5 ≥ 5
Subtract 1.5 from both the sides,
x + 1.5 - 1.5 ≥ 5 - 1.5
x ≥ 3.5
In short, She can watch 3.5 hours more in that week
Hope this helps!
To solve, you would first take the equation y-5=-8, and add 5 on each sides. (To solve an equation, you need to isolate the variables. Adding 5 on both sides will cancel out the "- 5". in order to do this you must do it to both sides so it will still be even.) You should now have Y = -3. to check this, you can say "-3 - 5 =", and your answer will be -8.
Answer:
-16
Step-by-step explanation:
1 - 8 - 9 = - 16
Answer:
False
Step-by-step explanation:
y=5x + 5
0=5 (5)+5
0=10+5
0≠15
False
