X is amount of books.
x ≤ 9 if the books are 2 inches thick.
x ≤ 18 if the books are 1 inches thick.
Equation for 1 inches.
x ≤ 18
Equation for 2 inches.
2x ≤ 18
Equation for both.
x + 2y = 18
y is amount of 2 inch books
This one equation above is standard form.
2x-8+28+64=180°
2x-84=180
2x=96
x=48
Answer:
the area is 20 in
Step-by-step explanation:
3 times 4 is 12. since we used 3 inches out of the 11, we can only multiply the 8 inches with 1. 8 times 1 is 8. 12+8=20.
Answer:
x=2/3
Step-by-step explanation:
(2x+1)/2 = 2 1/3/4
Multiply 4 on both sides:
2x+1=2 1/3
Rewrite:
2x+1=7/3
Subtract 1 on both sides:
2x=4/3
Divide 2 on both sides:
x=2/3
Thus x=2/3

Answer:
![-\frac{13}{6}](https://tex.z-dn.net/?f=-%5Cfrac%7B13%7D%7B6%7D)
Step-by-step explanation:
To find the slope between two points, we can use the slope formula. The slope formula is:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
where m is the slope and (x₁, y₁) and (x₂, y₂) are two points.
Plugging in (-1, 7) and (5, -6) for (x₁, y₁) and (x₂, y₂) respectively, we get:
![m=\frac{y_2-y_1}{x_2-x_1}=\frac{-6-7}{5-(-1)}=\frac{-13}{6}=-\frac{13}{6}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%3D%5Cfrac%7B-6-7%7D%7B5-%28-1%29%7D%3D%5Cfrac%7B-13%7D%7B6%7D%3D-%5Cfrac%7B13%7D%7B6%7D)
So the slope between the two points would be
