The equation:
models the amount of money in your wallet. Where:
x: Represents the number of weeks from today
y: Represents the total in dollars
This graph is indicated in the figure bellow. The slope of this graph is 10, that is, the term accompanying the variable x. The slope of a line is the number of units the line rises (or falls) vertically for each unit of horizontal change from left to right. So, in this problem, this represents how much your adding to your wallet each week. You are adding $10 dollars for x weeks.
Answer:
(a - b)^2 = 49 - 4b^2 +2ab
Step-by-step explanation:
Given: a^2 + b^2 = 7b (assuming A is really “a”)
b^2 + (2b - a)^2 = 7^2
Find; (a - b)^2
Plan: Use Algebraic Manipulation
Start with b^2 + (2b - a)^2 = 7^2 =>
b^2 + 4b^2 - 4ab + a^2 = 49 by expanding the binomial.
a^2 + b^2 + 4b^2 - 4ab = 49 rearranging terms
a^2 + b^2 -2ab - 2ab + 4b^2 = 49 =>
a^2 - 2ab + b^2 = 49 - 4b^2 +2ab rearranging and subtracting 4b^2 and adding 2ab to both sides of the equation and by factoring a^2 - 2ab + b^2
(a - b)^2 = 49 - 4b^2 +2ab
Double Check: recalculated ✅ ✅
(a - b)^2 = 49 - 4b^2 +2ab
The total volume of the glass is 100cm3 = 100ml
Explain: the glass is divided in 4 parts, the glass is 3/4 when 75 cm3 of orange is poured in. To find 1 part, calculate 75/3=25 (cm3). So the total volume is 4 parts, then 25*4=100 (cm3)
The inequality that represents the number of each type of fabric that Naomi has is:
Let the number of short-sleeved shirts she made be x
Let the number of long-sleeved shirts she made be y
Length of clothes used to make a short-sleeved shirt = 9 yards
Length of clothes used to make a long-sleeved shirt = 16 yards
Length of short-sleeved shirts made = 9x
Length of long-sleeved shirts made = 16y
Total length of fabric used = 53 yards
