Simplify the equation with pemdas
first parentheses
distributive property
a(b+c)=(ab)+(ac)
(5y+2)2=(10y)+(4)
10y+4-96=0
10y-92=0
add 92 to both sides
10y=92
divide both sides by 10
y=9.2
Answer:
D
Step-by-step explanation:
Required equation
The height of statue of liberty is 93 meters.
Step-by-step explanation:
Given : Howard has a scale model of the Statue of Liberty. The model is 15 inches tall. The scale of the model to the actual statue is 1 inch : 6.2 meters.
To find : Which equation can Howard use to determine x, the height in meters, of the Statue of Liberty?
Solution :
The model is 15 inches tall.
The scale of the model to the actual statue is 1 inch : 6.2 meters.
Let x be the height in meters of the Statue of Liberty.
According to question, required equation is
Cross multiply,
x=15 x 6.2
x=93
Therefore, the height of statue of liberty is 93 meters.
Answer:
The slope of the line is m=-0.8 and y-intercept = 5.6.
Step-by-step explanation:
Given : Line of best fit :
To find : Write a scenario that could work for the following line of best fit and explain the slope and intercept in this context?
Solution :
Line of best fit :
Scenario - Let a person has 5.6 dollars and he spend 0.8 dollars every weekend.
So, The slope is 0.8 but also negative as there is decrements.
The y-intercept is 5.6, the value we obtain from the equation when we set x=0.
So, The slope of the line is m=-0.8 and y-intercept = 5.6.
