X= total acres on farm
x * 21%= 168
move decimal 2 places to the left to go from percent to decimal form
x * 0.21= 168
divide both sides by 0.21
x= 800 acres
ANSWER: There are a total of 800 acres on the farm

Answer:
Step-by-step explanation:
Slope of the line
Answer:
The negative solution is between -3 and -2
The positive solution is between 11 and 13
Step-by-step explanation:
we have
The formula to solve a quadratic equation of the form 
is equal to
in this problem we have
so
substitute in the formula
therefore
The negative solution is between -3 and -2
The positive solution is between 11 and 13
Answer:
Their y-intercepts are equal
Step-by-step explanation:
The y-intercept is the y-value where the function crosses the y-axis. In this problem, functions are presented in 2 ways: algebraically and in a table.
1) Fortunately, the algebraic equation is written in slope-intercept form; this means that intercept is easy to find. The slope-intercept form is y=mx+b, where b is the y-intercept. In function 1, the b value is 10.
2) Another way to describe the y-intercept is the y-value when x=0. So, the y-intercept on a table is wherever the x-value is 0. In this case, the first row represents when x=0. The table says that when x=0, y=10. This means that the y-intercept for function 2 is 10.
Since the y-intercept for both of the functions is 10, it can be said that the 2 functions have equivalent y-intercepts.
SA = 2s^2 + 4sh
= 2(3^2) + 4(3)(6)
= (18) + (72)
SA = 90
