the parent function y=1/x is translated so that its horizontal asymptote is y=-4 and its vertical asymptote is x=2.
Answer is: the vertical asymptotes occurs when the denominator equals zero. The current function has a horizontal asymptote at y=0.

Solve: x + 3 < 7
answer is: if we subtract 3 from both sides, we get: x + 3 - 3 < 7 - 3 x < 4 And that is our solution: x < 4 In other words, x can be any value less than 4.

solve 12 < x + 5
answer is: If we subtract 5 from both sides, we get: 12 - 5 < x + 5 - 5 7 < x That is a solution! But it is normal to put "x" on the left hand side ... ... so let us flip sides (and the inequality sign!): x > 7 Do you see how the inequality sign still "points at" the smaller value (7) ? And that is our solution: x > 7

how do you graph this y= -7x + 14
Answer is: The easiest way to graph it is to draw a coordinate system, then find out in which points this line intersects the axis. That means finding out the value of -7x+14 at x=0 (would be 14), and the value of x such as -7x+14=0 (x=2). Mark these two points and draw a straight line

Solve: 3y < 15
answer is: If we divide both sides by 3 we get: 3y/3 < 15/3 y < 5 And that is our solution: y < 5

x^2-3x=0
answer is: Where is a? In fact a=1, as we don't usually write "1x2" b = -3 And where is c? Well, c=0, so is not shown

How do I check the solution for 7m+8=71
Answer is: What you do is minus 8 on both sides which will now give you 7m=63 then you divide by 7 on both sides and that will give you m=9

Solve: -2y < -8
answer is: Let us divide both sides by -2 ... and reverse the inequality! -2y < -8 -2y/-2 > -8/-2 y > 4 And that is the correct solution: y > 4

What is the y-intercept of y=-2x+1
answer is: Use the slope intercept form of the equation for a line. y = mx + b In this equation m is the slope and b is the y-intercept. So, for your equation y = -2x + 1 The y-intercept is 1 and the way to write it as a point is (0, 1). This means that the graph crosses the y-axis at 1.

Solve: (x-3)/2 < -5
answer is: First, let us clear out the "/2" by multiplying both sides by 2. Because you are multiplying by a positive number, the inequalities will not change. (x-3)/2 ×2 < -5 ×2 (x-3) < -10 Now add 3 to both sides: x-3 + 3 < -10 + 3 x < -7 And that is our solution: x < -7
