The answer is m= -13
because 32-45=-13
The slope of the line is
(9-5) / (4- -2) = 4/6 = 2/3 .
If the x-intercept is -2 and the y-intercept is 1, then the equation of the line is
y = 1/2 x + 1 .
None of the choices is correct.
Answer:
5-m is the expression is equivalent to - m + 5.
The total R value is computed from the R-values of the components in the stack as ...
(inches of wood)*(R-value of wood) +(inches of fiberglass)*(R-value of fiberglass) +(inches of foam)*(R-value of foam)
= (4 in)(2 /in) +(2 in)(4 /in) +(3 in)(5 /in)
= 8 +8 +15
= 31
The total R-value of the wall is 31.
