Answer:
Step-by-step explanation:
3x^2 + 5x + 25 when x = 3
= 3(3)^2 + 5(3) + 25
= 3(9) + 15 + 25
= 27 +15 + 25
= 67
<h2><u>Answer</u> : </h2>
By observing the table we can conclude that for the number of years to travel back double the electricity is required .
i.e. for 5 years = 10 megawatts
therefore, the relationship between x and y can be depicted by the following equation :

In the least squares equation, ŷ = 10 + 20x, the value of 20 indicates ____________.
Y-Intercept
Answer:
1,187 bu/hr
Step-by-step explanation:
4.8 mi/hr
240 inches
Efficiency: 85% (0.85)
120 bushels/acre
1 acre = 6 272 640
1 mile = 63 360 inches
4.8 miles = 304 128 inches
120/6 272 640 x 240 = 5/1089 (bushels/inch)
5/1089 x 304 128 x 85% = 1 186.9 = 1187 bu/hr
Wow, that's hard for me :) Hope it's helpful
Let hamburger = fries + 50
2hamburger + 3fries = 1700 **Given**
2(fries+50) + 3fries = 1700
2fries + 100 + 3fries = 1700
5fries = 1600
fries = 320
hamburger = 320 + 50
hamburger = 370 cal
