Answer:
C
Step-by-step explanation:
The easiest way to determine this is to realize that time is the independent variable (n) and temperature is the dependent variable (a).
From the table, we can plug in the two points (n) into n of each equation and see if that equals the temperature values (a).
<em>A little thinking would get us to plug the numbers in C first.</em>

<em>Hence, C is the correct answer.</em>
Answer:
(-5, -3)
Step-by-step explanation:
Scale factor 1/2 means divide points by 2
Y=mx+b
slope=m
yint=b
we are given
slope=-2/3
point=(-3,-1)
y=-2/3x+b
input point -3,-
x=-3
y=-1
find b
-1=-2/3(-3)+b
-1=2+b
minus 3
-3=b
y=-2/3x-3
answer is D
Answer:
2x² + 12x + 10
Step-by-step explanation:
Area of a rectangle = width x length
Therefore,
Area = (x + 1)(2x + 10)
Expand the brackets: 2x² + 10x + 2x + 10
Combine like terms: 2x² + 12x + 10
A quadratic expression is an expression with the variable with the highest power of 2
Answer:
Step-by-step explanation:
6*( 5 + X) = 36
30 + 6X = 36
6X = 6
X = 1
