A Domain is the lowest and highest x value (-5,-2) is how it is formatted this means -5 to -2
Range is the lowest to highest Y value so (-3,3)
(-5,-2) - domain
(-3,3) - range
B Intercept are when the line crosses the axis labeled x so
(-2,0) and (2,0)
C F(1) means what is x when y is equal to 1 so we must estimate this
(-1,1) and (1.5,1)
D f(x) = -3 is when y is -3 so we look at the graph to see
-5 and 4 are the values for x
E f(x) < 0 means when y is above the x axis
This is between the x values of -2 and 2 or (-2,2)
Rate of change is m in y=mx+b
also, starting value=when x=0
since so many questions I will not show work
1. A positive
2.B negatvie
3.B negative
4.B negative
2. B y=5x+4
3. B y=7x-8
4. C 12x+6y=30
5. plumber=140
electrition=115
per our means how much does he charge for 1 hour so subsitute 1 for x or find where 1 is
1. 8
2. 15
3. 2
4. 1/2
5. 3
those are the answers in order, hope this helps!
Answer:
D
Step-by-step explanation:
11 1/4 divided by 3= 3.75 (3 3/4)
30 degree
The sum of isosceles triangle is 180 degree. And this triangle 2 sides have to be equal.
So one of our angle is 120 degree. Two angle will be 180-120 = 60 degree
Now one angle 60/2=30
