The answer is as follows:
$50 x 0.25 = $12.5 (This is how much Lea saves)
$50 - $12.50 = $37.50 (Price after discount)
Therefore, we can conclude that the amount taken off is $12.50 and the discounted price is $37.50.
If the equation is then the domain is the set of all real numbers.
We can replace x with any real number and compute to get some real number output for y. There are no division by zero restrictions to worry about, or issues with taking a square root of a negative number (since this isn't really a square root function).
The cube root of a negative number is negative. For example, because (-4)^3 = (-4)*(-4)*(-4) = -64.
In interval notation, the domain would be written as to indicate the entire real number line.
Answer:
x = 32.6666667
Step-by-step explanation:
12(x - 2) + 3x = 12(x + 6) + 2
Distribute;
12x - 24 + 3x = 12x + 72 + 2
Collect like terms;
15x - 24 = 12x + 74
Subtract 12x from both sides;
3x - 24 = 74
Add 24 to both sides;
3x = 98
Divide both sides by 3;
x = 32.6666667
Answer:
Step-by-step explanation:
1. - 3x + 32 = - x - 12
-3x + x = - 12 - 32
-2x = - 44
x = 44/2 = 22
2. 8x + 16 = x + 9
8x - x = 9 - 16
7x = - 7
x = - 7/7
= - 1
3. 3x + 2 = 2x - 55
3x - 2x = - 55 - 2
x = - 57
Answer:
18.9
Step-by-step explanation:
1) Simplify 4/5 + 3/5 to 7/5
7/5 + 3/5 x 5
2) Simplify 3.5 x 5 to 17.5
7/5+17.5
3) Simplify
94.5/5
4) Simplify
18.9
