Answer:
The answer is x=1
Step-by-step explanation:
-4(3x+6)+6=-30
-12x-24+6=-30
-12x-18=-30
-12x-18+18=-30+18
-12x=-12
-12x/-12=-12/-12
x=1
Answer:
6
Step-by-step explanation:
1/6 of 36=6
2/3 of 36= 24
24+6=30
36-30=6
Wait what's the question tho?
is it if this point is on the line?
cause it's not
-y=mx+b
3=-6(6)-3
-3=-36-3
-3 does not equal -39
hence, point is not on the line
Answer:
1- click
2--trick
3- track
4-trace
Step-by-step explanation:
equation (y=x+2) x y
y=-3+2 -3 -1
y=-1+2 -1 1
y=0+2 0 2
y=2+2 2 4
you can plot the points ( click)
<h2>equation (y=-x) x y</h2>
y=-(-2) -2 2
y=0 0 0
y=-1 1 -1
y=-3 3 -3
plot the points
<h2>equation (y=1) x y</h2>
y=1 no matter what the value of x -3 1
(-3,-1,0,2) -1 1
0 1
2 1
<h2>y=1/2 x +1 x y</h2><h2> y=-4/2 +1 -4 1</h2>
y=-2/2 +1 -2 0
y=1/2(0)+1 0 1
y=3/2 +1 3 2.5
there are no image for 5 and 6
Answer:
Explanation:
1. x represent the copybook while y represent the pen that is bought.
2. 2x + 3y = 9000 means that in order to buy 2 copybooks and 3 pen you have to pay 9000 LL.
3. Solve for the price of x and y
2x + 3y = 9000 (1)
4x + 2y = 8000 (2)
Multiply (1) by -2:
-2(2x + 3y = 9000)
4x + 2y = 8000
——————————
-4x - 6y = -18000
4x + 2y = 8000
—————————
-4y = -10000
y = -10000/-4
y = 2500
Substitute y value into (2):
4x + 2(2500) = 8000
4x + 5000 = 8000
4x = 3000
x = 3000/4
x = 750
Therefore, 1 copy book = 750LL and 1 pen = 2500 LL
