Answer:
x^2 - 7x - 1
Step-by-step explanation:
g(x) = x^2– 5x
f(x) = 2x +1
(g - f)(x)
expand to get
gx - fx
Slot in the values
(x^2– 5x) - (2x +1)
expand
x^2 - 5x - 2x - 1
x^2 - 7x - 1
Answer: x = -3
Step-by-step explanation:
2y + x = -15
y = 2x
2y = 2(2x) = 4x
4x + x = -15
5x = -15
x = -3
1. x= 27.6
2. x= 41
3. x= 30.2
I'm not sure what the triple thing is but hoped I helped with the other stuff.
Answer:
Assume the pair of dice are fair; if not, all bets are off!
Color one die green (G) and the other one red (R). There are 36 possibilities in throwing one green and one red die, eg (G1, R1), (G1, R2), etc; (G2, R1), (G2, R2), etc; etc; (G6, R1), (G6, R2), etc.
In the set of possible numbers from throwing a die, there are only 3 possibilities that sum to to 4: (G1, R3), (G2, R2), (G3, R1).
So the answer is 3/36, or one-twelfth.
Answer:
In the last two sections, we considered very simple inequalities which required one-step to obtain the solution. However, most inequalities require several steps to arrive at the solution. As with solving equations, we must use the order of operations to find the correct solution. In addition remember that when we multiply or divide the inequality by a negative number the direction of the inequality changes.
The general procedure for solving multi-step inequalities is as follows.
Clear parenthesis on both sides of the inequality and collect like terms.
Add or subtract terms so the variable is on one side and the constant is on the other side of the inequality sign.
Multiply and divide by whatever constants are attached to the variable. Remember to change the direction of the inequality if you multiply or divide by a negative number.
