Answer:
B. (x + 3) (x + 27)
Step-by-step explanation:
<em><u>To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:</u></em>
<em><u /></em>
<em><u>Group:</u></em>
<em><u /></em>
<em><u>Take out GCF (Greates Common Factor):</u></em>
x(x + 3) 27(x + 3)
(x + 27) (x + 3)
Rate = distance / time
Rate = 21 miles / 3 hours
Rate = 7 miles / hour
The answer is choice A. Hope this helps.
152... cuz 28 is perpendicular so... 180-28
The graph of g(x) will be moved 3 units up i believe!!
Answer:
Slope : The rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.
T-intercept : 8.5 represents the temperature in °C of the earth's surface in the year 1900.
Step-by-step explanation:
The average surface temperature of Earth rising steadily. Scientists have modeled the temperature by the equation, T = 0.02t + 8.50 where t represents years since 1900 and T is the temperature in ◦C.
Now, the slope of the model equation is 0.02 which means the rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.
Again, the T-intercept i.e. 8.5 represents the temperature in °C of the earth's surface in the year 1900. (Answer)
