The width of a picture frame is x inches and the length is x+3 inches, what is the value of x if the area must be 40 square inches
Answers
Answer:
x = 5
Step-by-step explanation:
Width = x inches
Length = (x+3) inches
Area = 40 sq inches
The area of a rectangular shaped object is given by :
Putting all the values,
Neglecting x = -8.
So, the value of x is 5.

Answers
Final answer:
The monthly cost, y, to use a cell phone for x minutes at a rate of 4 cents per minute can be modeled by a linearfunction. This is because the cost increases at a constant rate with the number of minutes used. In contrast, options A, B, and C involve non-constant rates of change.
Explanation:
The answer is D. The monthly cost, y, to use a cell phone for x minutes at a rate of 4 cents per minute. This is a linear function because it describes a constant rate of change, as the cost changes linearly with the number of minutes used. Each additional minute costs the same amount: 4 cents. So, if we plot the minute (x) versus cost (y), we would get a straight line. This is different from the other options where the rate of change is not constant. For instance, options A, B, and C describe scenarios with exponential decay or growth.

Answers
Step-by-step explanation:
We know that this particularly line can be named as :
- JK ←→
- LM ←→
This give us the following information :
- The line passes through the points J and K
- The line passes through the points L and M
One statement we can make is :
The points J , K , L and M are aligned. So the line passes through the points J , K , L and M.
We also know that given a line there are infinite planes that contain the line.
Given that the points J , K , L and M belong to the same line, we can state that :
There are infinite planes that contain the points J , K , L and M.
6 apples each and the bags with mangoes
contain 3 mangoes each. If David and his
friends ate 2 apples from each bag and 2
mangoes from each bag, what is the total
number of fruits left over?
Answers
Answer:
Step-by-step explanation: the step by step explanation is 6*4=24 so 24 apples then 3*2=6 so 6 mangoes then if 8 apples are ate then 4 mangoes are ate then (24+6)-(8+4)=30-12 so the answer is 18.
6 bags in total
4 bags x 6 apples each = 24 fruits
2 bags with 3 mangoes each= 6 fruits
Total 30 fruits
Friends ate 2 fruits from each of the 6 bags
They ate 12 fruits
30-12 = 18

y = 4 (x-2) ^ 2-1
Rewriting we have:
y = 4 (x ^ 2-4x + 4) ^ 2-1
Multiplying the common factor 2 we have:
y = 4x ^ 2-16x + 16-1
Adding the constant term we have:
y = 4x ^ 2-16x + 15
Answer:
y = 4x ^ 2-16x + 15
