Okay, we have 20 students, 15 of them like chocolate cake and the rest like cheesecake, to find the answer we have to subtract 20 - 15 and the answer is 5, so 5 students like cheesecake.
Answer:
-6x - 8y + 20 = 0
Step-by-step explanation:
If you have two points (x₁; y₁) and (x₂; y₂), you can use the formula to find the equation of a straight line:
![\tt\boxed{\tt(y_1-y_2)x+(x_2-x_1)y+(x_1y_2-x_2y_1)=0}\\\\ \text{in your case:} \ x_1=6; \ x_2=-2; \ y_1=-2; \ y_2=4, \ \ so:\\\\(-2-4)x+(-2-6)y+(6\cdot4-(-2)(-2))=0\\\\-6x-8y+(24-4)=0\\\\-6x-8y+20=0](https://tex.z-dn.net/?f=%5Ctt%5Cboxed%7B%5Ctt%28y_1-y_2%29x%2B%28x_2-x_1%29y%2B%28x_1y_2-x_2y_1%29%3D0%7D%5C%5C%5C%5C%20%5Ctext%7Bin%20your%20case%3A%7D%20%5C%20x_1%3D6%3B%20%5C%20x_2%3D-2%3B%20%5C%20y_1%3D-2%3B%20%5C%20y_2%3D4%2C%20%5C%20%5C%20so%3A%5C%5C%5C%5C%28-2-4%29x%2B%28-2-6%29y%2B%286%5Ccdot4-%28-2%29%28-2%29%29%3D0%5C%5C%5C%5C-6x-8y%2B%2824-4%29%3D0%5C%5C%5C%5C-6x-8y%2B20%3D0)
Answer:
88 inches
Step-by-step explanation:
Divide the shape into 2 shapes and add all side lengths.
20+8+8+16+12+24=88
Answer:
A.
Step-by-step explanation:
if they are similar then you can set up a proportion to solve.
5/x = 7/4
cross multiple to get 20=7x
x=20/7
