Answer:
(-10, 0) and (0,-5)
Step-by-step explanation:
For the function find x-intercept and y-intercept:
1. when y=0, then
2. when x=0, then
You get two points (-10, 0) and (0,-5). Plot them on the coordinate plane and connect, obtained line is the graph of the linear function
Answer:
y = 4
x = -16
Step-by-step explanation:
this time we should multiply the first equation with -1 because we only need to change its state of negativity
2x + y = -28
-2x - 2y = 24 ➡ -y = -4 ➡ y = 4
if 2x + y = -28 the 2x + 4 =-28 ➡ 2x = -32 x = -16
Answer: 310 feet
Explanation: Since they start at 1,00 feet , and hike to 1,310 feet, there would be a 310 feet difference.
Work: 1,310 feet - 1,000 feet = 100 feet
