Q8 q3.) solve the system by the substitution method.

The volume of gas a balloon can hold varies directly as the cube of its radius. imagine a balloon with a radius of 3 inches can hold 81 cubic inches of gas. how many cubic inches of gas must be released to reduce the radius down to 2 inches?

Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form. (2 points) y = 3x − 7 y = 3x − 5 y = 5x − 11 y = 5x − 9

Which equation can be used to calculate the area of the shaded triangle in the figure below? (5 points) 2(12 × 4) = 96 square feet (12 × 4) = 24 square feet 2(12 + 4) = 32 square feet (4 + 12) = 8 square feet
