Answer:
a) (-1,0) and (3,0)
b) x=1
c) (1, -4)
Step-by-step explanation:
As you can see in the graph below, the x intercepts of this graph are at (-1,0) and (3,0), the axis of symmetry is x=1, and the vertex is at (1,-4). Hope this helps!
Answer:
35/42 = b/7 and b= 35/6
Step-by-step explanation:
Our base is unkhown so it will be the variable in our equation :
- Let A be the area , h the height and b the base
- A = b*h
- 35/42 = b/7 this is the equation , let's solve it
- (35*7)/42 = b
- (35*7)/ 7*6 =b
- 35/6 = b
so b is 35/6 cm
Answer:
negative and increasing
Step-by-step explanation:
The graph in the interval b to c is below the x- axis and is therefore negative,
from b to c the slope of the curve is positive so it is increasing
I think its C but im not 100% sure.
Answer:
C. A = 150
Step-by-step explanation:
A + 3x = 180
A = 9x + 60
9x+60+3x = 180
12x = 120
x = 10
A+3(10) = 180
A +30 = 180
A = 150
