2.74 - (-19.4) = 22.14, so the freezer is 22.14°c colder. I hope that helps!
The predicted value of y when x =7 is -8.5
<h3>How to predict the y value?</h3>
Start by drawing the line of best fit through the points
See attachment for the graph.
From the attached graph, we have the following value
y = -8.5 when x = 7
Hence, the predicted value of y when x =7 is -8.5

Answer:
You would do this problem like a normal varible problem. x=10
Step-by-step explanation:
Since 9x is a right angle the inside would also be 9x
9x+4x+10+40=180
180 because that is how much a triangle equals
combine like terms
13x+50=180
subtract 50 from both sides
13x=130
divide by 13
x=10

Length (L): w + 3
width (w): w
Perimeter (P) = 2L + 2w
24 = 2(w + 3) + 2(w)
24 = 2w + 6 + 2w
24 = 4w + 6
18 = 4w
18/4 = w
9/2 = w
4.5 = w
Length (L): w + 3 = 4.5 + 3 = 7.5
Answer: width = 4.5 cm, length = 7.5 cm
