Basiclaly solve for y
8x+4y=16
minus 8x both sides
4y=-8x+16
divide by 4 both sides
y=-2x+4
Answer: 1,400 calories
Bianca jogged 1.25 miles per day for 8 days. so 1.25*8 would equal 10 miles.
Since she jogged 10 miles and burned 140 calories per mile, if we multiply 10*140, we would get 1,400.
So last month, she lost 1,400 calories.
Exponential decay is the answer
X as 6 and y as 8, -7 as x 3 as y, and -3 as x and -5 as y.
D) <span>The side lengths remain the same, and the position of the figures change.
