4. At which point do the equations y = x+3 and 15x + 20y = 0 intersect? A. 72, )
B. (- 12, 9)
C. (0,3)
D. These two lines never intersect.

Find the volume of the described solid.the solid lies between planes perpendicular to the x-axis at x = 0 and x=7. the cross sectionsperpendicular to the x-axis between these planes are squares whose bases run from the parabolay=-31x to the parabola y = 30/x.a) 441b) 147c) 864d) 882

Evaluate the expression. (9 + 5)(3 + 2)0

Put the equation in slope intercept form by solving for y
