Answer:
y = 4x + 32
Step-by-step explanation:
Given: Temperature at sunrise = 32°F
y is the temperature after x hours of sunrise
Temperature change is 4°F/hour.
The equation of a line in slope intercept form is given by
y = mx +c
where m is the slope, which is the change in value of y to the value of x
and c is the value of y at x = 0
At sunrise, x =0 and y =32
∴ c = 32
Also we see that the change in temperature to that of time is 4/1 = 4
∴ m = 4
Substituting the values of m and c in the equation of line, we have
y = 4x +32

Answer:
Step-by-step explanation:
<u>Let's check his work by simplifying the given expression.</u>
- 2(x - 2) - 2(3)
- => 2x - 4 - 6
- => 2x - 10
When I compare Marty's result and this result, they are un-equal. Hence, Marty is incorrect.
<u>Marty's mistake</u>
- Marty must've got the problem wrong because of not understanding the distributive property.
- He probably forgot to multiply -2 by 2. Instead, he only subtracted 2 when he should've subtracted 4 from 2x.
