slope intercept form is y = mx + b
so the answer is y = 2x - 3
Answer:
The domain of this exponential function is (all real numbers).
Step-by-step explanation:
The domain is all real numbers because according to the x-axis the function passes through all numbers the negative and positive. As you see the graph is continuous which means it will keep on going.
I hope this helps!
F = 1/2 J = 2M
J = 4M
M + F + J = $280
M + 2M + 4M = $280
7M = $280
M = $280/7 = $40
J = 4M = 4x40 = $160
F = 1/2 (160) = $80
40 + 160 + 80 = $280
Mary saved $40
Fred saved $80
John saved $160
