The y-intercept is the starting point. Since the temperature started at -7, we know that b in y = mx + b has to be -7. m is the slope which in our case is 3 because the temperature is changing every hour. So, because the temperature is going up, it's +3. Our equation should be y = 3x - 7.
Answer:
The first is not equivalent, second is.
Step-by-step explanation:
2x-3.9x+7.5=5.9x+7.5
The first is not equivalent, second is.
We have
C is the cost
x is the units of a product at the factory
If
C= 35170
we need to find the value of x
The equation given is

so we have the value of C, so the equation if we substitute the value of C is

we need to isolate the x

In that month,490 units can be produced for $35170.
The answer is 60x-52y
Hope that helped!
