Answer:
60,120,180
3,6,9
Step-by-step explanation:
10x+3y=43
-9x-y=-20
From second equation,
y=-9x+20
Substitute third equation into first equation,
10x+3(-9x+20)=43
10x-27x+60=43
-17x=43-60
-17x=-17
x=1
y= -9+20= 11
Option B
Answer:
Sorry
Step-by-step explanation:
Answer:
y=-3/4x-5
Step-by-step explanation:
m=y2-y1/x2-x1
m=1-(-5)/-8-0
m=1+5/-8
m=6/-8
m=-3/4
y-y1=m(x-x1)
y-(-5)=-3/4(x-0)
y+5=-3/4x
y=-3/4x-5
Answer:
Step-by-step explanation:
Okay so lets put the x values on one side and the whole numbers which are the numbers without variables on the right side.
so now,
m/9 = -2/3 + 7/3
now lets use the inverse operation of division to multiply 9 to separate it from the variable
9(m = -2/3 + 7/3)9
m = -18/3 + 63/3
which can be simplified to,
m = -6 + 21
so,
m = 15.
Hope this helps!
