Answer: -2
Step-by-step explanation:
(-4+-3) -(2-7)
-7 - -5
-7+5= -2
Answer:
(-4) & (-3) have same sign ( -ve) . So add and put the (-) sign for the result.
2 is a positive number and (-7) is a negative number. Subtract and put the sign of the bigger number for the result.
(-4 + (-3) ) - (2 - 7) = -7 - (-5)
= - 7 + 5
= -2
18 mph so B is correct 16+2= 18
If simplifed, it'll be -v
21
f(x) =x^2 - 6x + 21
f(xl =0
substitute 0 for x
f(0) = 0^2 - 6(0) + 21
0. = 0 - 0 + 21
0. = 21
