This is number 8. the second person got number 9
How to solve 7-10: if a coordinate (x, y) is on the line, then f(x) = y.
7. Since x is 6, look at the graph, which shows that y (or f(x)) is 4. (look at picture)
8. Same thing as 7. you will see that f(x) is 15.
9. The other way around. since we know y = 2, looking at the graph shows us that x = 3.
10. Repeat process of 9. x = 10.
How to solve 11 + 12: slope formula (rise-over-run)
11. (14-4)/(12-6) = 10/6 = 5/3.
12. (16-14)/(18-12) = 2/6 = 1/3.
(If possible brainliest is appreciated :D)
So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!
Answer:
5
Step-by-step explanation:
100= 75 + x2
x=5
<span>Ans : According to the Equation -
10.2638 + 0.0491x
= 10.2638 + 0.0491 X 748 ( Because x= 748, given )
= 10.2638 + 36.72
= 46.99
= 47 (Approximately)</span>
