What s the vertex y=3x^2-18x +30​

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.

Select all of the following expressions that are equal to 2.5.

Write the component forms of vectors u and v, shown in the graph, and find v − 2u. u= (< -3, -2> , < -3, -1> , < -2, -2> , < -2, -1> ) v= (< -5, 1> , -4, 0> , < 0, -4> , < 1, -5> ) v-2u= (< 5, 3> , < 0, 4> , < 4, 0> , < 5, -3>
