It would take him 9 hours to drive 522 miles since if you divide 638 with 11 you would get 58 and if you divide 522 with 58 you'll get 9.
Inequalities are the lines on a graph they plot if they're an order pair or not
Hopefully this helped. :)
If you meant to say k=(-3)
First thing you would do is plug in the (-3) to a
Your equations would look like this:
k(a) = 4(-3) + 2
You would multiply 4 × -3, giving you -12.
k(a) = 12 + 2
Then you would add 12 + 2, giving you 14.
k(a) = 14
k(a) would equal 14.
Answer:
The Center is (-2 , 3)
Radius of the circle is 3
Step-by-step explanation:
∴ the center is ( -2, 3)
radius of thw circle is 3
a)
Lets p = # of fruit pies sold and j = # of bottles of fruit juice sold
Together both classes sold 79 items: p + j = 79
Fruit pie sold sold $1.65 each and bottle of fruit juice sold $1.36 each and together earned $118.17 = 1.65p + 1.36j = 118.17
Now you have two equations
p + j = 79 --> p = 79 - j
1.65p + 1.36j = 118.17
Substitute p = 79 - j into 1.65p + 1.36j = 118.17
1.65(79 - j) + 1.36j = 118.17
130.35 - 1.65j + 1.36j = 118.17
- 0.29j = - 12.18
j = 42
Substitue j = 42 into p = 79 - j
p = 79 - j = 79 - 42 = 37
# of fruit pies sold = 42 and # of bottles of fruit juice sold = 37
b)
Mr. Sanchez's class : $1.65 (37) = $61.05
Mr. Kelly's class: $1.36 (42) = $57.12
Mr. Sanchez's class sold more money than Mr. Kelly's class.
c)
$61.05 - $57.12 = $3.93
Mr. Sanchez's class earned $3.93 more than Mr. Kelly's class
