Answer:
<u>Two</u>
============================
Step-by-step explanation:
The solution for any system of equations is the intersection points between the graph that representing the system of equation.
So, for the given system of equation, we have a circle and a parabola.
As shown in the figure, The circle and parabola are intersects at two points
So, there are two solutions for the system of equations on the graph.
So, The answer is option two.
The function is nonlinear because it does not have a constant rate of change
Answer:
57
Step-by-step explanation:
(62+5-3)+(2-9)
(67-3)+(-7)
64-7
= 57
Move all terms to the left side and set equal to zero. Then set each factor to equal to zero giving you..
<span> First subtract how tall it was 7 1/2 years ago from how tall it is now.
57 - 40 1/2 =</span>
<span />57 - 40.5 = 16.5 or 16 1/2
<span>So in the 7 1/2 years the tree grew 16 .5 or 16 1/2 feet. To get the average yearly growth for the 7 1/2 year period you have to divide the 16 1/2 feet by 7 1/2 years.</span>
<span>It makes it much easier if you change the fractions to decimals. </span>
<span>16 1/2 = 16.5</span>
<span>7 1/2 = 7.5</span>
<span>16.5 ÷ 7.5 = 2.2 or 2 1/5 feet per year</span>
<span>Hope this helps. :)</span>
