The sum of 2 numbers is equal to 10. The difference between those same two numbers is equal to -4 find the numbers.
Akimi4 [234]

Answer:

3 and 7

Step-by-step explanation:

For problems like these I take the largest number in this case 10, and start writing out what 2 numbers would give me 10. 0+10, 1+9, 2+8, 3+7...while doing that I subtract the numbers as well. thus 3+7=10 3-7=-4

Write an equation of the line that is parallel to 2x + 4y = 6 and passes through the point (6, 4). A) y = 2x + 4 B) y = 2x - 8 C
Lynna [10]

Answer:

\large\boxed{D.\ y=-\dfrac{1}{2}x+7}

Step-by-step explanation:

\text{Let}\\k:\ A_1x+B_1=C_1\\\\l:\ A_2x+B_2y=C_2\\\\\text{then}\\\\k\ \parallel\ l\iff A_1=A_2\ \wedge\ B_1=B_2\\==========================

\text{We have the equation:}\ 2x+4y=6\\\\\text{Therefore the equation of a parallel line is:}\ 2x+4y=C\\\\\text{Put the coordinates of the given point to the equation and solve for}\ C:\\\\(6,\ 4)\to x=6,\ y=4\\\\C=2(6)+4(4)\\C=12+16\\C=28\\\\\text{The equation in the standard form:}\\\\2x+4y=28

\text{Convert to the slope-intercept form}\ y=mx+b:\\\\2x+4y=28\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\4y=-2x+28\qquad\text{divide both sides by 4}\\\\y=-\dfrac{2}{4}x+\dfrac{28}{4}\\\\y=-\dfrac{1}{2}x+7

Please help me with this system of inequalities​!
erica [24]
Part A: y<4x-8 is a dotted line intercepting the y-axis at -8, and increasing by a value of 4, with shading bellow the line. The Second equation (which I can't fully type out) is a solid line intercepting the y-axis at 5,decreasing by a value of -5/2, and has shading above the line.

Part B: It does not because the point (5,-8) doesn't appear where the shaded areas meet.
