Answer:
c. BC
Step-by-step explanation:
It is the possible one
A coefficient of r = -1 is a negative so the dots would move downward as they move to the right ( higher dots are on the left side, lower dots on the right side. As the coefficient gets closer to -1 the dots form more of a straight line then being scattered across the graph.
The last graph, which is marked with the blue dot is the correct one.
Answer:
16
Step-by-step explanation:
Since line CE is equal to 32 and line DB is the bisector (cut into the middle) of line CE then line CF would be half of line CE. Hence the reason that line CF is equal to 16
Answer:
Savings = $13
Step-by-step explanation:
$0.12 = 1 kilowatt-hour
So,
For Top-Freezer Refridgerator:
$0.12 × 529 = 1 × 529 kilowatt-hour
$63.48 = 529 kilowatt-hour
For Side-by-Side Refridgerator:
$0.12 × 634 = 1 × 634 kilowatt-hour
$76.08 = 634 kilowatt-hour
Savings = Side-by-Side Refridgerator - Top-
Freezer Refridgerator
Savings = $( 76.08 -63.48 )
Savings = $12.6
Savings = $13
Connor has 14 quarters and 28 dimes.
Step-by-step explanation:
Given,
Worth of coins = $6.30 = 6.30*100 = 630 cents
We know that,
1 quarter = 25 cents
1 dime = 10 cents
Let,
Quarter = x
Dime = y
According to given statement;
25x+10y=630 Eqn 1
The number of dimes is 14 more than the number of quarters
y = x+14 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
Dividing both sides by 35
Putting x=14 in Eqn 2
Connor has 14 quarters and 28 dimes.
