Answer:
y=\frac{4x}{5}-5
Step-by-step explanation:
linear equation
y=mx+b
We can see that when x=0 y= -5
THis means that b= -5 so we have
y=mx-5
We then know that when x=5 y= -1 so we have
-1=5m-5
Solve this and get m= 4/5
So we have
SSA is not valid for congruence. SSA gives two possible triangles, one which is congruent and one which is not.
Answer:
Loose sweets are of better value
Step-by-step explanation:
<u>Packed</u>
120 g = £1.49
price per gram = £1.49/120= £0.0124
<u>Loose</u>
100 g = £0.89
price per gram= 0.89/100= £0.0089
Comparing prices per gram, we can see loose sweets cost less (0.0089<0.0124), so is better value
