Really any option.
Explanation: A triangle can be obtuse of acute, either of these answers will make one of those.
Answer:
Below.
Step-by-step explanation:
(a). The x estimations of the turning points are -1.8 and 1.1, according to the graph.
(b). Where the graph crosses the x axis are the solutions. x = -3, 0, and 2 are the values.
Answer: x+y = 40
We have a = 1, b = 1, c = 40
=================================
Explanation:
x = number of nickels
y = number of quarters
The equation 0.05x+0.25y = 5 represents adding the values from the nickels and quarters
0.05x = value of just the nickels
0.25y = value of just the quarters
0.05x+0.25y = total value = 5 dollars
That's how that first equation was formed.
-------------
Based on those x and y definitions above, we know that x+y = 40 because there are 40 coins of either nickels or quarters only. So the sum of the two coin counts must be 40 overall.
The equation x+y = 40 is the same as 1x+1y = 40. This equation is in the form ax+by = c where,
a = 1
b = 1
c = 40
-5 is your y-intercept so you would start at point(0,-5)
then you go up seven and to the right 1
the graph is attatched
