B=5 this is because you need to isolate the b so you first add 3 to both sides and then it’s going to be 5b=25 and then divide 5 from both side to get b by itself and it will be b=5
A: 8*9= 72 or 72 because it is the lowest multiple of 8 and 9
B: euclidean theorem (35,63) (35,28) (7,28) (7,0) gcf= 7 or 7 because 7 is the biggest number that goes into both numbers.
C: 7(5+9) or 35 is a factored into 7 and 5 and 63 is factored into 7 and 9 and 9 is factored into 3 and 3
Answer:2.50
Step-by-step explanation:
The value of x is the number inside the parenthesis, so h(-4) gives x a value of -4.
The equation says when X is ≤ -4 use the first equation
So h(-4) = -1/2(x) -15
= -1/2(-4) -15
= 2 -15
= -13
When x = -2 (h(-2) ) use the 2nd equation:
h(-2) = 20-3x^2
=20-3(-2)^2
= 20-3(4)
=20-12
=8
Now you have -13 + 3(8)
= -13 + 24
=11
The answer should be 11
