Answer:
A and D are the true number sentences
To solve this problem you must use the information given in the problem above:
1. You have that he jogs 
to the park and then 
to the playground, then he jogs 
miles to the bridge and 
to his house.
2. Therefore, as you can see, Jerry completes his jog when he arrives to his house. So, he is 
from his house.
Then, the answer is:
Answer:
no
Step-by-step explanation:
It is x^(1/2)
Answer:
There are 24 nickels
Step-by-step explanation:
Let x represent the number of nickels
Let y represent the number of quarters
—————————————————————
Value Value

of of each all
Coin Coin Coin Coin

Nickels | x | $0.05 | $0.05x
Quarters | y | $0.25 | $0.25y
—————————————————————
Totals 28 ——— $2.20
•••••••••••••••••••••••••••••••••••••••••••••••••
The first equation comes from the “Number of coins” column.
(Number of nickels) + (Number of quarters) = (total number of coins)
Equation: x + y = 28
—————————————————————
The second equation comes from the “value of all coins” column.
(Value of all nickels) + (Value of all quarters) = (Total value of all coins)
0.05x + 0.25y = 2.20
Remove the decimals by multiplying each term by 100:
5x + 25y = 220
—————————————————————
So we have the system of equations:
{x + y = 28
{5x + 25y = 202
Solve by substitution. Solve the first equation for y:
x + y = 28
y = 28 - x
Substitute (28 - x) for y in 5x + 25y = 220
5x + 25 (28 - x) = 220
5x + 700 - 25x = 220
-20x + 700 = 220
-20x = -480
x = 24
The number of nickels is 24.
————————————————————
Substitute in y = 28 - x
y = 28 - (24)
y = 4
The number of quarters is 4.
————————————————————
Checking:
24 nickels is $1.20 and 4 quarters is $1.00
That’s 28 coins.
Indeed $1.20 + $1.00 = $2.20

Answer:
-4
Step-by-step explanation:
Slope can be found with 
Pick two points on the graph that the line runs through
(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2
Insert the coordinates into the formula
Therefore the slope is -4
