Step-by-step explanation:
Addition Property of Equality
We can add the same number to both sides and still keep the equality.
First, we took away three from each side: x+3−3=8−3x+3−3=8−3
Then we were left with five: x=5x=5
The division property of equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal.
Multiplication Property of Equality
Stated simply, when you divide or multiply both sides of an equation by the same quantity, you still have equality. ... In the example below the variable is multiplied by 4 , so we will divide both sides by 4 to “undo” the multiplication.
Let x=−7x=−7. Substitute −7−7 for x: 4(−7)?=−284(−7)=?−28
Check your answer: 4x=−284x=−28
Simplify: x=−7x=−7
Subtraction Property of Equality
You can subtract the same number from both sides of an equation and get an equivalent equation.
(f + g)(x) = 3x² + 2x - 1
g(x) = 2x - 2
(3x² + 2x - 1) - (2x - 2)
3x² + 2x - 2x - 1 + 2
3x² + 1
f(x) = 3x² + 1
Answer:
16. 29 and 30
17. C. 30 D. 31
Step-by-step explanation:
16. Given the inequality c ≤ $30, which is used to represent the situation, it implies that possible value of c must be equal to $30 or less than $30.
Two possible solutions form the options given would be:
29 and 30.
29 is less than 30, and 30 is equal to 30.
17. The inequality given is b ≥ 30.
This implies that possible solutions will be equal to 30 or greater than 30. It cannot be less than 30.
The solutions that apply would be:
30 (this is equal to 30) and 31 (this is greater than 30).
The remaining options don't satisfy or make the inequality statement true.
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
The ordered pairs are: (100, 135) and (500, 375)
The first number is the number of minutes of usage and the second number is the charge of the month.
The slope is: ( 375 -135) / (500 - 100) = 240/400 = 0.6
