4. What is the x-intercept of the trend line, y = -0.13x + 11.2? Is that possible in a real-world situation? Explain.

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
