Answer:
y= 1 over 3x
Step-by-step explanation:
any linear function graphs a straight line and if you need multiple answers then 2 over 3x = y- 1 is also a lineat function
<em><u>show the total cost for the first 4 months of this cellphone plan
:</u></em>
m 1 2 3 4
C ( $ ) 70 115 160 205
<em><u>Solution:</u></em>
Given that,
The equation is:
C = 45m + 25
Where,
C is the total cost in dollars
m is number of months
<em><u>show the total cost for the first 4 months of this cellphone plan
</u></em>
<em><u>First month</u></em>
m = 1
C = 45(1) + 25
C = 45 + 25
C = 70
<em><u>Second month</u></em>
m = 2
C = 45(2) + 25
C = 90 + 25
C = 115
<em><u>Third month</u></em>
m = 3
C = 45(3) + 25
C = 160
<em><u>Fourth month</u></em>
m = 4
C = 45(4) + 25
C = 205
<em><u>Thus the table is:</u></em>
m 1 2 3 4
C ( $ ) 70 115 160 205
Thus the table is formed
This is a cubic function with the highest degree of 3, the correct order would be:
f(x) = -1.5x^3 + 10x^2 - 5
Teds minimum grade he needs on his third test is 65
85 + 60 + 65 = 210
210 divide by three (as there are three tests) = 70
