Answer:
1.89
Solution:
We have -44x - 86 = -3
First, we move the non x terms to the RHS of the equation. To do this, we add 86 to both sides.
Note: if a = b, then a + c = b + c
Therefore, -44x - 86 + 86 = -3 + 86
or, -44x = 83
Next, divide both sides by -44, which is the coefficent of x
Note: if a = b, then a ÷ c = b ÷ c
-44x
-44
=
83
-44
or, x = -1.89
Explaination:
This is right I guess
The vertex (5,39)
5 is the value of x. 39 is the value of y. y is the cost function of the minimum value in dollars.
(5,39) vertex means that <span>Buying five of each type of plant costs $39, which is the lowest possible cost.</span>
Answer:
+ 12
Step-by-step explanation:
8 - (- 4) = 8 + 4 = 12
T=(h*5)+6.5 should be it because it is the number of hours multiplied by 5 days and then you add the 6.5 hours
Answer:
16 hours
Step-by-step explanation:
company A $800 plus $16 per hour
company B $720 plus $21 per hour
im going to start with 10 and go from there
company A
16 x 10 = 160
800 + 160 = 960
company B
21 x 10 = 210
720 + 210 = 930
it needs to go up so lets try 15
company A
16 x 15 = 240
800 + 240 = 1040
company B
21 x 15 = 315
720 + 315 = 1035
one more maybe 16
company A
16 x 16 = 256
800 + 256 = 1056
company B
21 x 16 = 336
720 + 336 = 10 56
