Answer:
No restriction
Domain:
Step-by-step explanation:
We are given function as
we know that this is exponential function
and x+4 as an exponent over e
so, we can select any real values of x as an exponent
and this function will be defined for all values of x
so, there won't be any value of x where f(x) is undefined
So, domain would be
Answer:
y = -5/4x -3
Step-by-step explanation:
y = mx + b
2 = -5/4 (-4) + b
2 = 20/4 + b
2 = 5 + b
2 - 5 = b
-3 = b
You multiply the number of cars(bottom row) by 4 to get the number of tires(top row) so if there are 4 cars then there will be 16 tires. If you think about it, there are 4 tires on a car so you would multiply the number of cars by 4 to get the number of tires
You need to isolate/get m by itself in the equation:
3(m + 7) = 6(m + 2) Distribute 3 into (m + 7), and distribute 6 into (m + 2)
(3)m + (3)7 = (6)m + (6)2
3m + 21 = 6m + 12 Subtract 3m on both sides
21 = 3m + 12 Subtract 12 on both sides
9 = 3m Divide 3 on both sides
3 = m
PROOF
3(m + 7) = 6(m + 2)
3(3 + 7) = 6(3 + 2)
3(10) = 6(5)
30 = 30
