It would be 28-10=x because your ending up with 28 after earning 10 you would get that. Hope this works!
<span>To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y -intercept--this should be of the form (0, b) . ... Therefore, the equation for this line is y = - x + 2 .</span>
Answer:
c.126 red
Step-by-step explanation:
red+green+yellow=350
10% out of 350 are yellow
0.1 times 350=35
350-35=315
3/5 out of 315 are green
red is not green so
2/5 of what is left is red
2/5 of 315 is red
2/5 times 315=430/5=126
126 red
4. 3x+(-x)=4
3x-x=4
2x=4
x=4/2
answers:
x=2
y=-2
5.
y=x-1
4x-y=19
-x+y=-1
4x-y(cross the y’s out they cancel eachother)=19
3x=18
x=6
-6+y=-1
y=-1+6
y=5
answers:
x=6
y=5
