The linear model of this case takes the form:
y = a(x-b) + k
<span>The cost of having a package delivered has a base fee of $9.70
this is "k" >>>>> k=9.7 (fixed amount of fee)
THEN
</span>
<span>Every pound over 5 lbs cost an additional $0.46 per pound
that means: 0.46(x-5)
in other words, if the package weighs foe example 9 pounds, then 9-5=4, it will cost 0.46*4 for these 4 extra pounds
Finally we have the linear form of this: C = 0.46 (W - 5) + 9.7
</span>
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
For -4+2, plot -4, then move to the right 2 spaces. You should land on -2.
For -4+(-2), plot -4 then move the left 2 spaces. You should land on -6.
(-1.7, -4.9)
to reflect across the x-axis multiply the x-value by negative 1
Answer:
33g
Step-by-step explanation:
10% of 30g is 3g so add 30g to 3g and you get 33g.
