What does 6262-62y mean?
It means you have been put on the " drug check list"
Slope intercept form for x plus 2y equals 6?
x + 2y = 62y = -x + 6y = -1/2 x + 3
X plus 8y equals 22 -8x-2y plus 10?
8x + 64y = 176 Add: 62y = 186 so y = 3 and x = -2 This assumes you mean "equals 10", not "plus 10"
Use the Substitution method to solve the system of equationsx plus y equals -4 and x - y equals 2?
x + y = -4x - y = 2x - y = 2x + y - y = 2 + yx = 2 + yx + y = -42 + y + y = -42 + 2y = -42 - 2 + 2y = -4 - 22y = -62y/2 = -6/2y = -3x = 2 + yx = 2 - 3x = -1The solution of the system is (-1, -3)
How do you find the y-intercept of a linear relationship from an equation?
The y-intercept of a linear equation is the point on the y-axis at which the line cuts.It could be found by plugging x = 0 in the given linear equation.For example,Consider 3x + 2y = 6. To find the y-intercept just plug x = 0 in the equation.3(0) + 2y = 62y = 6y = 3(0, 3) is the y-intercept of the linear equation 2x + 3y = 6.Note:In the same way we can find the x-intercept by plugging y = 0 in the given linear equation.
Solve this equation using addition method x subtract y equals 6 and 3y equals x plus 22?
x - y = 63y = x + 22you need to solve these equations simultaneously.first get all your x's and y's on the same side.x - y = 63y - x = 22if you add these two equations together, the x's will cancel as one is positive and the other negative.x - y + 3y - x = 22 + 62y = 28y = 14then substitute y is 14 into one of the original equations to find xx - 14 = 6x = 20
How can you use the equations of two non-vertical lines to tell wether the lines are parallel or perpendicular?
-- Rearrange the equation of Line #1 into the form y1 = A1x1 + B1-- Rearrange the equation of Line #2 into the form y2 = A2x2 + B2-- Compare the constants A1 and A2.If A1 = A2, then the lines are parallel.If A1 = -1/A2, then the lines are perpendicular.Get them both into the form: y = mx + c.If they are parallel then their gradients (given by m in the equation above) will be equal.If they are perpendicular, then the product of their gradients will be -1.Examples:2y = 4x + 5, y - 2x = 62y = 4x + 5 → y = 2x + 5/2 → gradient = 2 y - 2x = 6 → y = 2x + 6 → gradient = 2The gradients are equal, thus the lines are parallel2y = x + 4, y + 2x = 32y = x + 4 → y = 1/2 x + 2 → gradient = 1/2 y + 2x = 3 → y = -2x + 3 → gradient = -2Product of gradients is 1/2 x -2 = -1, thus the lines are perpendicular.
How old were all presidents when first elected?
The usual form of the question is "what was the age at which each became President?" (ignoring any distinction between those who were elected or those who took over at the death or resignation of their predecessor). Including ALL Presidents, and counting those later elected "in their own right" increases the age a bit.The median age overall (whether elected or not) is 54 years, 11 months.Most by far were in their 50s (twenty-four), esp. 50-55 (fifteen).The range of those elected has been from 43 (Kennedy) to 69 (Reagan); Theodore Roosevelt became President at 42 (on the death of McKinley). No others under 45 have been elected, and only two were over 65 when elected (W.H. Harrison at 68, and Reagan), so we could say "mostly between 45 and 65".
