Answer:
The car drove for 1,024 miles.
Step-by-step explanation:
x=miles driven
y=days driven
448.76=29x+0.24y
448.76=29(7)+0.24y
448.76=203+0.24y
245.76=0.24y
y=1,024
Answer:
Bianca's height = 42 inches
Step-by-step explanation:
Let x be the Bianca height.
Given:
Meredith height = 60 inches
We need to find the Bianca height.
Solution:
From the given statement the Meredith's height is
of Bianca's height plus 32 inches, so the equation is.
Meredith's height = ![\frac{2}{3}(Bianca\ height)+32](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%28Bianca%5C%20height%29%2B32)
Substitute Meredith's height in above equation.
![60=\frac{2}{3}x+32](https://tex.z-dn.net/?f=60%3D%5Cfrac%7B2%7D%7B3%7Dx%2B32)
Now we solve the above equation for x.
![\frac{2}{3}x=60-32](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx%3D60-32)
![\frac{2}{3}x=28](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7Dx%3D28)
By cross multiplication.
![x=\frac{3\times 28}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%5Ctimes%2028%7D%7B2%7D)
28 divided by 2.
![x=42\ in](https://tex.z-dn.net/?f=x%3D42%5C%20in)
Therefore, the height of the Bianca is 42 inches.
The answer is 69632 because of PEDMAS
Letter C is correct.
When the function is even, (all powers are even) both ends will go in the same direction.
In this case since the leading coefficient is negative, both ends will go down.
