Answer: Hello mate!
our equation in this problem is:
Now we have a rule in mathematics when the denominator is zero, the function is undefined (because you can not divide by zero). The two denominators that we have here are:
2x + 3 and x - 7, and now we can see for which values of x these denominators are zero in order to discard the values of x
1) 2x + 3 = 0
x = -3/2 = -1.5
and
2) x - 7 = 0
x= 7
(2x + 3); wich is equal to zero when x = -1.5 and x-7, wich is equal to zero when x = 7.
So just looking at these fractions you could assume that x = 7 and x= -1.5 are not possible solutions.
Answer:
C, between 3 and four hours.
Step-by-step explanation:
The y-axis is where we will find the number of chairs he makes, so we look there for 30. It isn't there, BUT, there is 32 and 24. Between 32 and 24 chairs, it lands between 3 and 4 hours. Hope this helps!
To write this in function notation, first find the coordinates of the 2 points given.
Assuming each line segment below the y axis decreases by 1
Assuming the lines past the X axis to the right increase by 1
Point A - (0,-5)
Point B - (5,0)
Find the slope using the equation for slope.
M = y2 - y1/ x2 - x1
M = 0 - -5/ 5 - 0
M = 0+5/5
M = 5/5 = 1 - slope is 1.
Now put the information you know.
Slope and y intercept in slope y intercept equation
Y = mx + b
Y = 1x + - 5
Y = X - 5.
In function notation the equation is y = X - 5.
