Question 1003202: Hello, I am working on a series of questions with the equation y-3=3(x+1). I have the slope-intercept form y=3x+6, and the standard form 3x-y=-6? Now, I am trying to find an equation in standard form of a perpendicular line that passes through (5,-1). I took y=mx+b and solved for b=2/3, then y=-1/3x+2/3 and switched it around to y+x/3=2/3. Is this correct? I am confused because standard form is Ax+By=c, if my answer should be x/3+y=2/3?? Seems like that would be in the correct form. Thank you for your time!

Question 1003207: Jewish Voice live webcast with jonathan bernis & Chris mitchell
Last week ISIS addressed Israel in Hebrew. This week ISIS released a video spoken in fluent American-accented English that addresses the U.S. and President Obama. The gruesome video is reported to taunt the United States over a recently failed attempt to free ISIS captives. The U.S., did however succeed in freeing some 70 Iraqi hostages in imminent danger of being killed by ISIS, and for this, ISIS conducted four revenge beheadings on the video. Can anything stop this evil and inhumane group of thugs? And how does their horrific behavior fit into the perilous times foretold of in Last Days Bible prophecy?
It is growing ever more important to have a biblical
and prophetic perspective of the news.

Question 1003370: This question appeared on our homework: If we stand on top of a 160-foot building and throw a ball up into the air with an initial velocity of 18 feet per second, then the height of the ball above the ground is given by
H=-14t^2+17t+160.
Here, t is time in seconds since the ball was thrown and H=H(t) is the height of the ball above the ground measured in feet. Determine when the ball hits the ground. Include the correct unit of measure in your answer and round to two decimal places.

Question 1004278: The perimeter of a rectangular -shaped field is 138 ft. The width is 29 ft shorter than the length. Find the length and width of the field.
Let x =the length
Let y = the width
Write two equations. First complete the sentence that describes the formula for the perimeter of a rectangle.
Perimeter of a rectangle equals twice the length plus twice the width
Use the above formula and the assigned variables, x and y to write an equation.
2x+2y=138.
Recall the condition that the width of the rectangle is 29 ft shorter than the length. Now, write an equation for the width in terms of the length
