Answer:
The answer to your question is the first choice
Step-by-step explanation:
Data
Point = (-2, -5)
Process
Evaluate each of the equations on the point given.
A. y = x - 3
-5 = -2 - 3
-5 = -5 This is true so the point is on this line
B. y = 2x
-5 = 2(-2)
-5 = -4 The result is false so the point is not on this line
C. y = -3x
-5 = -3(-2)
-5 = 6 The result is false so the point is not on this line
D. y = x + 3
-5 = -2 + 3
-5 = 1 The result is false so the point is not on this line
1. You have that the area of the rectangle defg is 108 cm² and the scale factor is 3/4. Therefore, the scale factor of the area of the rectangle <span>defg </span>is:
=(3/4)²
=9/16
2. Keeping this on mind, you have that the area of the rectangle <span>qrst is:
</span>
A2=A1x16/9
A2=(108 cm²x16)/9
A2=1728 cm²/9
A2=192 cm²
The answer is: The area of the rectangle qrst is <span>192 cm².</span>
Simply divide the price by the number of ounces to get the price per oz.
$1.39 ÷ 12 = about $.1158 cents per oz
$2.79 = 24 = about $.11625 cents per oz.
By a very small amount the $1.39 bottle is a better deal.
You could also think that $1.39 for 12 oz is $2.78 for 24 (I doubled both numbers)
$2.78 for 24oz is a drop cheaper than $2.79 for 24 oz so $1.39 is a slightly better buy.
A1 or just a as it is in the equations is just the initial term of the sequence. In this case a1=1
r is the common ratio which is that constant ratio found by dividing any term by the term preceding it...
In this case r=3/1=9/3=27/9=etc=3
So a1=1 and r=3, C. is your answer.
