Answer:
Step-by-step explanation:
$120= the amount to pay for the shoe
$20 paid for the month
Balance to pay = $100
Then 3% interest rate on credit card = 3% of $100=$3
Therefore amount to pay = $3+$100=$103
 
        
             
        
        
        
Answer:
9 degrees
Step-by-step explanation:
The temperatire was -3 and then rose by 12, -3 + 12 = 9
 
        
             
        
        
        
m<3 =72°
This is because m<1 and m<3 are vertically opposite.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
$19.50
-$15.50=
$4.00
1slice of pizza and 1soda is $4
so 2slices of pizza and 2 sodas is $8
$15.50-$8=$7.50
Now you have 3 slices of pizza left
$7.50/3slices=$2.50
1slice of pizza is $2.50

Step-by-step explanation:
*Note:
The definition of a derivative is the slope of the <em>tangent</em> <em>line</em>.
<u>Step 1: Define</u>
<em>Identify.</em>
f(-2.4) = -1
f(-1.9) = -8
<u>Step 2: Differentiate</u>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>.
