Hi, can someone help and check over these answers for me, please?

Match each equation (a)-(f) with its graph among figures I-VII. Note that the the graphs are labeled with Roman numerals, and their a and y scales may not be equal. (a) y - -73 5 corresponds to graph IV (b) y - x + 3 corresponds to graph V (c) y - x 3 corresponds to graph (d) 10y = x corresponds to graph VI (e) 11 = y corresponds to graph (f) - 3x + 2 - y corresponds to graphFind the equations of the lines that pass through the point (-1, -3) and are parallel to and perpendicular to the line with equation y = -9x + -1. (a) Parallel: y -9x + 12 (b) Perpendicular: y 26 9 Select a blank to input an6 The graph above illustrates your north-south distance in km from the edge of a lake in hours from noon (where positive values mean you are north of the lake). When the graph passes through the axis, it means you pass by the edge of the lake (so your distance is 0). Complete the following description of your journey, selecting the correct descriptions of directions and filling in the numerical values for the indicated distances and speeds. "At noon I am a distance of km from the lake relaxing. I then jump on my bike and start to cycle the lake at a speed of km/h. At 3pm, I stop for a rest and a picnic for three hours. I then jump back on my bike and cycle the lake at a speed of km/h. At 8pm | arrive at my house which is a distance of km from the lake."Write an equation that represents the following function. The energy, E, expended by a swimming dolphin is proportional to the cube of the speed, v, of the dolphin. Use k for any constant of proportionality in your answer.

The value you report drops with time. Straight-line depreciation assumes that the value is a linear function of time. If a 2000 dollar refrigerator depreciates completely in 9 years, find a formula for its value as a function of time, x, in years. value = y = -222.22 + 2000 dollars X CLOSE Input an expression below y = -222.22 + 2000For the function illustrated above, identify the concavity and whether the function is increasing or decreasing on the intervals indicated below. (a) On [A, B], the function is decreasing and concave up (b) On [B, C], the function is increasing and concave down (c) On [C, D], the function is increasing and concave down (d) On [D, E], the function is decreasing and concave up (e) On [E, F], the function is increasing and concave up Select a blank to input an answer SAVE ?
