Answer:
<u>Hanna is 8 years old.</u>
Step-by-step explanation:
Hanna = x
Tina = 4x
Sum = 40.
Hanna =?
Hanna + Tina = 40
4x + x = 40
5x = 40
x = 40/5
x = <u>8</u>.
Hanna is <u>8 years</u> old.
This is a vertical line that goes through all points with an x-coordinate of -9.
To graph it, I can give you a couple of points this line goes through so you can draw it more easily.
Points that are on line: (-9,0) and (-9,1)
The answer is D they are proportional equal to negative 4<span />
The y-intercept is: y = 7x - 44
The question is asking to calculate and round of the value in to the greatest non zero place and base on the said number, I would say that the answer would be from 0.64 to 1. I hope you are satisfied with my answer and feel free to ask for more if you have question and further clarification
