Answer:
Not sure if you mean 2x+y=-4 or 2x+y=4
either way put it in y=mx + b form (slope intercept)
Step-by-step explanation:
so for 2x+y = -4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ -4 so m= -2/1 (slope) and b= -4 the place the line crosses the y axis
so for 2x+y = 4 first move everything away from the side with "y" by -2x from each side you get y= -2x+ 4 so m= -2/1 (slope) and b= 4 the place the line crosses the y axis
24/108= 6/27 (divided by 4)
6/27= 2/9 (divided by 3) or 0.222222
Answer:
<u><em>E</em></u>
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
slope = rise / run = 7 / 1 = 7
m = 7
y-intercept = 0
So:
<em>y = 7x + 0</em>
<em>y = 7x</em>
The absolute value of p is the distance between the vertex and the focus and the distance between the vertex and the directrix. (The sign on p tells me which way the parabola faces.) Since the focus and directrix are two units apart, then this distance has to be one unit, so.
2x + x = 60 that is your equation. Simplify it and you get 3x = 60. 60/3 equals 20 so you have 20 boys but multiply it by 2 since you have twice as many girls and you get 40 girls total.
