(x^2 - 4^2)^2 = x^4 - 4^4
(x^4 - 4^4) (x^2 + 4^2) = x^2 - 4^6
The Angela's solution is wrong cause when you multiply you get a different answer.
1. the answes for the graph ones is the 3rd and 4th graph because both graphs are 1 line and a line is infinite
2. (-3,5) x=(-) y=(+)that means that it must to the left and up part of graph, therefor it is the 4th graph
1. it would be the 4th graph that you didn't show because none of the included answers are correct
A) the only mistake is changing the mixed number to an improper fraction .
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
