Answer:
its scientific notification is 5×10^9
Answer:
bx = - 3
Step-by-step explanation:
- 2(bx - 5) = 16
- 2bx + 10 = 16
- 2bx + 10 - 10 = 16 - 10
- 2bx = 6
- 2bx ÷ - 2 = 6 ÷ - 2
bx = - 3
<span>y = -1/2x +2 1/2</span>
General equation;
y = mx + c
Calculating the slope;
Change in y/ (change in x) = gradient m
(2-1)/(1-3) = - 1/2
Replacing m gives;
y= -1/2x + c
Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is
y = -1/2x +2 1/2
No because if that happened they wouldn’t be able to do it again so yeah
