Part A
The first thing we must do for this case is to rewrite both expressions.
We have then:
1/2 (7x + 48) = (7/2) x + 24
- [1 / 2x - 3] + 4 (x + 5) = - (1/2) x + 3 + 4x + 20 = (7/2) x + 23
Answer:
We note that the first expression is greater than the second for all values of x.
Part B:
A new expression that is greater than both written expressions is:
(7/2) x + 25
For all values of x, this expression is always greater.
Answer:
(7/2) x + 25
Answer:
See Explanation
Step-by-step explanation:
A positive integer is a perfect square if it can be expressed as the product of two same positive integers.
Any number that cannot be written this way is a non-perfect square.
Since the integers are not presented, we will quickly examine the perfect squares between 1 and 50.
The perfect squares are: 1,4,9,16,25,36 and 49.
- 1=1 X 1
- 4=2 X 2
- 9=3 X 3
- 16 =4 X 4
- 25 =5 X 5
- 36 =6 X 6
- 49 =7 X 7
Every other positive integer in the numbers 1-50 apart from those listed above is a non-perfect square.
You can figure that out as follows:
QS : QS' = 4 : 8 = QU : QU' = 5 : 10 = 1 : 2
Then the scale factor is <span>of the dilation is 2 (magnification)

Answer:
x = 1 ⇔ y = -2.4
x = 2 ⇔ y = -1.8
x = 3 ⇔ y = -1.2
x = 4 ⇔ y = -0.6
Step-by-step explanation:

→ Rearrange to make y the subject

→ Multiply everything by -1

→ Divide everything by 5

⇒ Substitute x = 1, 2, 3 and 4
