Rate of change <span>a </span>rate<span> that describes how one quantity </span>changes<span> in relation to another quantity. It is also called the slope. To calculate the rate of change in temperature, we use the expression:
Rate of change = change in temperature / change in time
</span>Rate of change = -25.5 / 1.5
Rate of change = -17 °C / min
The negative sign signifies a drop in temperature per minute.
Answer:
1.66667
Step-by-step explanation:
9------1
15-----?
We divide 9 by 9 to get 1 so we divide 15 by 9 to get ?
15 / 9 = 1.66667
Answer:Y= 3x-13
Step-by-step explanation: (5,2) Y= 2 X= 5. M = 3
Y=mx+b
2= 3(5)+b
2= 15+b
-15=-15 +b
-13=b
Ok so basically solve for y
x-y=12
27+3y=2x
27+3y=2x
subtract 3y from both sides
27=2x-3y
2x-3y=27
x-y=12
multiply by -2
-2x+2y=-24
add them
2x-3y=27
<u>-2x+2y=-24 +</u>
0x-1y=3
-y=3
y=-3
y coordinate is -3
2.
y=2x+14
-4x-y=4
y=2x+14
subtract 2x from both sides
y-2x=14
mulitply both sides by -2
-2y+4x=-28
add the 2 equations
-2y+4x=-28
<u /><u>-y-4x=4 +</u>
-3y+0x=-24
-3y=-24
divide both sides by -3
y=8
y coordinate is 8
1. y coordinate is y=-3
2. y coordinate is y=8<u>
</u>
24 ÷ 4 = 6
6 × 8 = 48
5 × 48 = 240
240 × 0.033814 = 8.11536
8.11536 fluid ounces should be purchased.
