Answer:
y=x+1
m=1
b=1
Step-by-step explanation:
-2x+2y=2
+2x +2x
2y=2+2x
divide by 2
y=1+x
rewrite
y=x+1
Since b is the y intercept, b would equal 1.
The slope of the line, or m, would be 1 as well.
First of all the repeated digits numbers are 66,77 and 99 Total 3
Numbers beginning with 6 Total 3 (63,67 and 69).
Numbers begin with 7 Total3
and begin with 9 Total 3.
answer is 12
Answer:
x=10, y=5
Step-by-step explanation:
For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.
x-2y=0
x=2y
You can substitute 2y as x on the first equation (x+4y=30).
2y+4y=30
6y=30
y=5
Plug y=5 into any equation.
x+4(5)=30
x+20=30
x=10
a.) you start with 19=h/3-8 so you add 8 to both sides then you simplify 19+8 to 27 so the equation then becomes 27=h/3 from there you multiply each side by 3 so its 27*3=h then you simplify 27*3 which leaves you with 81=h u then switch it around and your final answer h=81
b.) you start with 0.6x +0.8=1.4 first you subtract 0.8 from both sides so the equation is 0.6x=1.4-0.8 then you simplify 1.4-0.8/ so it then becomes 0.6x=0.6 u then divide both sides by 0.6 so the equation is now x=0.6/0.6 you then simplify 0.6/0.6 so you are left with x=1
