Answer:
a. yes the constant rate of change is proportional because at each time t is increasing by 1 and c by .50
b. yes because each time it is increasing t by 1 and c by 2.5
Step-by-step explanation:
The answer to this is y = 7x + 15
Answer:
The temperature decreased by 32 degrees.
Step-by-step explanation:
The surface area is given by:
S.A = 2 * (area of the top) + 2 * (area of the front) + 2 * (area of one side)
Substituting values we have:
S.A = 2 * (20) + 2 * (16) + 2 * (24)
S.A = 120 cm ^ 2
Answer:
The surface area of the rectangular prism is:
S.A = 120 cm ^ 2
<span>We see the numbers on a number line

</span><span>You need to add both distances
</span><span>
|-9| + 3 = 9 + 3 = 12
</span><span>half
</span><span>12 : 2 = 6
</span><span>Now , we measure the distance towards the center section
</span><span>1 way
-9 + 6 = -3
2 way
3 - 6 = -3
Answere : -3
