Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you want to find out what the slope is, you have to remember what the formula is first....
so in this case -3 would be the 
because it's the y in the ordered pair and it's the second one. Then one of the 5's would be 
and 9 would be 
and then the other 5 would be 
.
now if we plug it in
now we can tell that we can't divide by zero so the slope would be unidentified and that's it.
Answer:
Joey has 18 nickles and 27 dimes in his piggy bank.
Step-by-step explanation:
1 nickle = 5 cents
1 dime = 10 cents
$1 = 100 cents
$3.15 = 135 cents
Let
n represent the number of nickles, n>=0
d represent the number of dimes, d>=0
Joey counted a total of 45 coins that added up to $3.15:
n + d = 45
5n + 10d = 315
n = 18 nickles
d = 27 dimes
Answer:
[- 4, ∞ )
Step-by-step explanation:
the expression inside the radical must be greater than or equal to zero
x +4 ≥ 0 ⇔ x ≥ - 4
domain: x ∈ [- 4, ∞ )
