Answer:
y=2x-3
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
y=2x-3
Answer: r = 11
Step-by-step explanation:
We know that the point (-2, r) lies on the graph of:
2*x + y = 7.
Then, if we that point is on the graph of the equation, we can replace the values and we will have:
2*(-2) + r = 7
and now we solve this for r-
-4 + r = 7
r = 7 + 4 = 11
r = 11
Answer:
x=2
Step-by-step explanation:
3x+1=x+5
Subtract x from each side to get all the variables on one side
3x-x+1=x-x+5
2x+1 = 5
Subtract 1 from each side to get all the constants on the other side
2x+1-1 = 5-1
2x= 4
Divide each side by 2
2x/2 =4/2
x =2
Answer:
Step-by-step explanation:
If the radius of the circle is equal to
and the area is given as 45, then
which simplifies to
and to the nearest tenth,
r = 3.9
