4 0

Answer:

Step-by-step explanation:

area of triangular endface = ½×6×8 = 24 cm²

area of rectangular endface = 4×8 = 32 cm²

area of each endface = 24+32 = 56 cm²

area of each 3×10 face = 30 cm²

area of 3×4 face = 12 cm²

area of base = 8×3 = 24 cm²

surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²

Which is an equation of a line that has a slope of -1/3 and passes through the point (-5, 2)?
kramer

Answer:

y= -⅓x +⅓

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

This form is also known as the point-slope form.

Since the slope is given to be -⅓, m= -⅓.

y= -⅓x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= -5, y=2,

2= -⅓(-5) +c

2 =  \frac{5}{3}  + c \\ c = 2 -  \frac{5}{3}  \\ c =  \frac{1}{3}

Thus, the equation of the line is y= -⅓x +⅓.
