Answer in scientific notation: 8.3x10^-3
Wouldn’t you just for part a, insert different x values and solve to get your y value. and do that over and over again with different numbers to create a data table. and then for part b you’ll just make a graph and put down the points. so for the first slot, do 0 for x. y will equal -1 after solving, so your first plot for part b can be (0,-1) and continue on from there
Answer: x=-20
Explanation: Multiply both sides by 10
7x = -140
Divide both sides by 7
7x/7 = -140/7
x=-20
