Answer:
2. x + y
-1.375 + -2.75 = -4.125
Step-by-step explanation:
1. x - y
-1.375 - -2.75 = 1.375
2. x + y
-1.375 + -2.75 = -4.125
3. x/y
1.375/-2.75 = 0.5
4. x * y
-1.375 * -2.75 = 3.78125
Answer:
Its the last option
y = 1488.33x + 23800 ; $172,600.
Step-by-step explanation:
The slope of the trend line = (median value for 2000 - median value for 1940) / 60
= 89300 / 60
= 1488.33.
So the equation is 1488.33x + 23,800
Estimate for 2040
is 1483.33* 100 + 23800
= 172,600.
Answer:
x = -2
Step-by-step explanation:
-2x + 4x = -4 + 0
2x = -4
2x/2 = -4/2
x = -2

Part A: The algebraic equation for the situation is 2x - 3 = 5
Part B: Bob has 4 brand new music CD's
Step-by-step explanation:
Translate the situation into an algebraic equation:
- Ann has 5 brand new music CD’s, which is 3 less than twice the amount that Bob (x) has
- Find the value of x (the number of brand new CD's Bob has)
Part A:
∵ Bob has x brand new CD's
∵ Ann has 5 brand new music CD’s, which is 3 less than twice
the amount that Bob has
- That means multiply x by 2 and then subtract 3 from the product
and equate the answer by 5
∵ Twice x 2x
∵ 3 less than twice x = 2x - 3
∴ 2x - 3 = 5
The algebraic equation for the situation is 2x - 3 = 5
Part B:
Let us solve the equation to find the value of x
∵ 2x - 3 = 5
- Add 3 to both sides
∴ 2x = 8
- Divide both sides by 2
∴ x = 4
Bob has 4 brand new music CD's
