Factor 2xy - 4x plus 8y - 16?
( 2xy - 4x ) + ( 8y - 16)2 ( xy - 2x ) + 2 ( 4y - 8 ) Answer
What is the ordered pair for 2x plus 4y equals 16 and 2x-4y equals 0?
2x + 4y = 16 <=> 2x + 4y - 16 = 0 2x - 4y = 0 2x - 4y = 2x + 4y - 16 -8y = -16 y = 2 Substituting the known value for y in either of the original equations enables x to be determined. 2x + (4*2) = 16 : 2x = 16 - 8 : x2x = 8 : x = 4 2x - (4*2) = 0 : 2x - 8 = 0 : 2x = 8 : x = 4. The ordered pair satisfying both equations is (4,2)
What is the collect like term of 6 plus - 2x - 8 - -3 plus 12x - -4y?
6-2x-8+3+12x+4y 10x+4y+1 Note that - -3 = +3 and that - -4y = +4y
How do you solve this problem what is the value of the expression 2x squared plus 3xy - 4y squared when x equals 2 and Y equals 4?
x = 2 so x squared = 4 and 2x squared = 2 times 4 = 8; y = 4 so xy = 2 times 4 = 8 and 3xy = 3 times 8 = 24; y squared = 4 times 4 = 16 and 4y squared = 4 times 16 = 64; so 8 + 24 - 64 = 32 - 64 = -32
How can i write and equation of the line that passes through the givin point and is parallel to the givin line 0-8 8x 4y 5?
Write the equation of the line that passes through the point (0, 8) and is parallel to the line with equation 8x + 4y = 5.SolutionTwo lines are parallel if they have the same slope.First, we write the slope-intercept form for the given line:8x + 4y = 5 subtract 8x to both sides;4y = -8x + 5 divide by 4 to both sides;y = -2x + 5/4So, the slope of the two lines is -2.By using the point (0, 8), we can write the point-slope form of the required line:(y - y1) = m(x - x1)(y - 8) = -2(x - 0)y - 8 = -2x add 8 to both sides;y = -2x + 8 add 2x to both sides;y + 2x = 8 or2x + y = 8This is the general form of the line that passes through the point (0, 8) and is parallel to the line 8x + 4y = 5
