Answer:
288
Step-by-step explanation:
What subject is it as I need a background to answer this question
Follow the order of operations
1. parentheses (13+5) = 18
2. multiplication 21*(13+5) = 21*18 = 378
3. add 9 + 21*(13+5) = 9 + 378 = 387
Hope this helps!
Y = mx + b
slope(m) = 5
(6,2)...x = 6 and y = 2
sub and find b, the y int
2 = 5(6) + b
2 = 30 + b
2 - 30 = b
-28 = b
so the equation for this line is : y = 5x - 28
y = 5x - 28.......when y = -3
-3 = 5x - 28
-3 + 28 = 5x
25 = 5x
25/5 = x
5 = x <==== ur x coordinate
