-18- -27 = -45 -45- -15 = -30
Answer:
y = 1/3x
Step-by-step explanation:
It is impossible to know the exact equation of the graph without actually seeing the graph itself or atleast having more information. Therefore, using the information provided and assuming that the graph crosses both the x and y-axis at point (0, 0) then the equation would be the following
y = 1/3x
This equation shows that the graph has a slope of 1/3 and crosses the x and y axis at point (0, 0) like mentioned above and shows in the picture attached below.
Yes because it has one right angle (90°)
(-7)^2 and 5^3 are your answers
Let Alex (the youngest) be n
Sam is n+3 because he is three years older
George is n+5 because he is 2 years older than Sam (n+3 +2) = n +5
All their ages summed = 35
So
n + n +3 + n + 5 = 35
Combine like terms
3n + 8 = 35
<u> - 8 -8 </u> subtract 8 from both sides of the equation
<u>3n </u> =<u> 27</u>
3 3 divide both sides by 3 and get n= 9
So Alex is 9
Sam is 12 since he is 3 years older than Akex
George is 14 since he is 2 years older than Sam
9 + 12 + 14 = 35
