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:
24
Step-by-step explanation:6 x 8 = 48 = 48/ 1/2 =24
Depends on how much percent you have to put down for the house. Like if it’s 10% then just subtract 10% from the cost of the house.
Factor:
(m+5)(m+7)
Solve for the numbers inside, set it = to 0:
m+5=0 >solve
m=-5
m+7=0>solve
m=-7
