What is the distance between (-11, -20) and (-11, 5)?

One integer is 8 times another. if the product is 72, then find the integers

Find the domain and range of the following function f(x) = 51x - 21+ 4

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
