The graph of the piecewise function f(x) is shown.

On a coordinate plane, a piecewise function has 2 lines that connect. The first line is horizontal to the y-axis at y = 4 and goes to (0, 4). The second line goes from (0, 4) through (4, 0).

What is the range of f(x)?
{f(x)| –∞ {f(x)| –∞ {f(x)|4 {f(x)|0≤f(x)<∞}

Find the value of x. round the length to the nearest tenth

Jimmy can run 3.5 miles in 20 minutes. how far can ne run in one hour and ten minutes?

20 points for the answer. this is for real , don't put random ! a rectangle has a length of 4 centimeters and a width of 7 centimeters. what is the effect on the perimeter when the dimensions are multiplied by 5? the perimeter is increased by a factor of 5. the perimeter is increased by a factor of 20. the perimeter is increased by a factor of 25. the perimeter is increased by a factor of 100.
