Answer:
188
Step-by-step explanation:
10*5*4 - 6*2
So first make it into slope intercept form y=mx+b
1/2x-3y=8
subtract 1/2x from both sides
-3y=8-1/2x
multiply both sides by -1
3y=1/2x-8
divide both sides by 3
y=1/6x-8/3
the x intercept is when y=0
so set y to zero
0=1/6x-8/3
add 8/3 to both sides
8/3=1/6x
multiply both sides by 6
16=x
the x intercept is 16
Answer:
Step-by-step explanation:
1
We can set it up like this
15 2 30
---- × ----- = -----
1 3 3
then divide to simplify
30/3=10
you're answer is 10
I hope I've helped!
Answer:
you would have to use repletion
Step-by-step explanation:
2x^2+5x+7=20
-7 -7
2x^2+5x=13
/5 /5
2x^2+x=2.6
4+2x=2.6
-4 -4
2x=-1.4
/2 /2
x=-0.7
