Answer: C (18)
Step-by-step explanation: If we plug in 7 for z, 3 times 7 is 21. 21-3=18.
Answer:
the answer is -1.8
Step-by-step explanation:
35 is the answer
Explanation, the sum of interrior angme is 180degree
x+(3x+40)= 180
or, 4x= 180-40
or, x= 140÷ 4
or x = 35
Answer:
40%
Step-by-step explanation:
10000 = 5000 = 50% + 9000 = 40%
To find it, evaluate it at the endpoints and the vertex
in form
f(x)=ax²+bx+c
the x value of the vertex is -b/2a
given
c(t)=1t²-10t+76
x value of vertex is -(-10)/1=10
evaluate c(0) and c(13) and c(10)
c(0)=76
c(13)=115
c(10)=76
it reached minimum in 2000 and 2010
porbably teacher wants 2010
the min value is $76
