3rd one
Reason:
Point slope formula: y-y1=m(x-x1)
y1=-4
x1=1
m=1/2
Put it all together and you get a final answer of:
y-(-4)=1/2(x-1)
two negs make one pos
so,
final answer:<span>y+4=1/2(x-1)</span>
Answer:
-2
Step-by-step explanation:
16= -4(x-1)+4
16 - 4 = -4x + 4
12 = -4x + 4
12 - 4 = -4x
8 = -4x
x = 8 ÷ -4
x = -2
Answer:
Step-by-step explanation:
4/5a*3/2a^2
4*3/5a*2a^2
12/10a^3
6/5a^3
therefore ur answer is 6/5a^3
Step-by-step explanation:
change the unit
50 km per 1 hour
50 km/h = 50,000 m/ 3600 s = 13.8 m/s
the lorry speed is 13.5 m/s or 0.3 m slower than the limit
