Answer:
-7.25
Step-by-step explanation:
Given,
The stock is dropping at the rate of $1.45 each hour,
So, the change in price of the stock in one hour = - $1.45,
Thus, the total change of the stock in 5 hours
= 5 × change in 1 hour
= 5 × 1.45
= -$ 7.25
∵ A terminating decimal number is always a rational number ( however it is negative )
i.e. the rational number that represents the change in the price per share after 5 hours is -7.25.

Explanation: Took the quiz
Answer:
x < - 2
Step-by-step explanation:
given - 4.9x + 1.3 > 11.1 ( subtract 1.3 from both sides )
- 4.9x > 9.8 ( divide both sides by - 4.9 )
Remembering to reverse the direction of the inequality symbol as a result of dividing by a negative quantity.
x < - 2 ← inequality reversed
solution set : x ∈ ( - ∞, - 2 )
Answer:
x is over 2 :)
Step-by-step explanation:
How can estimation be used to make sure the answer is reasonable?
A.
Answer: Brianna paid $42.89.
Estimation: $19 + $12 = $31
$31 + $12 = $43
Brianna paid about $43 for the shoes.
B.
Answer: Brianna paid $25.78.
Estimation: $19 – $12 = $7
$19 + $7 = $26
Brianna paid about $26 for the shoes.
C.
Answer: Brianna paid $49.78.
Estimation: $19 + $12 = $31
$31 + $19 = $50
Brianna paid about $50 for the shoes.
the slope intercept form is the rate of change between any two points on a line it always is the same. The constant rate of change is called the slope of the line. Slope is the ratio of the rise, or vertical change, to the run, or horizontal change.
So Slope intercept form is basically Rise over Run.
