Answer:
Step-by-step explanation:
You want x alone on the left side.
x is being multiplied by 3 and by c.
The opposite operation of multiplication is division. You must divide 3xc by 3c to end up with just x.
You must do the same operation to both sides of an equation, so divide both sides by 3c.
Divide both sides by 3c.
Simplify both sides.
Answer:
168
Step-by-step explanation: 6 times 7 equals 42. Add 42 to 126 and Laurette has a total of 168 cards now.
<span>For part a,
y < x
y > -2x
</span><span>Point B: (3,1) plugin x=3, y=1 y < x 1 < 3
</span>which is true, so point B satisfies the first inequality<span>You can graph the inequality y > 2x+5 and see which schools are in the shaded region
I'm sorry but I can't do B and C
But I hope this helps!</span>
Consider f, such that f(x)=y, where x is in the Domain of f, and y is in the Range of f.
Let f(a)=b. So, (a, b) is in the graph of f.
The inverse function of f,
(if exists) is such that if f(x)=y, then
.
So if (a, b) is a particular point in the graph of f, then (b, a) is a point in the graph of
.
A point where they intersect is a point where (a, b)=(b, a), that is a=b. Among our choices, only (2, 2) satisfies this condition.
Answer: (2, 2)
