Answer:
x-5=sqrt(2x+5)
then square both sides
x2-10x+25=2x+5
x2-8x+20=0
rest is trivial
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
If both the x values are the same it will be a vertical line and the equation will be x = whatever the x value is in the ordered pair.
Answer:
To find the radius You have to take the circumference of the circle and divide it by 2 times π (pi)
To find the center you draw a chord across the circle (a line across the circle near the edge so it cuts the circumference in two places- if you didn't know) then you find the mid point of the chord, and add a chord or two to determine where they meet in the center
Step-by-step explanation:
Answer:
Given, m = 3 and n = 4
5×3 + 4×4 – 3
15 + 16 - 3
31 - 3
28
don't forget to like and mark me
X + y = 90 because the 2 angles add up to 90
Now m < x = five times m < y, so x = 5y or y = x/5
so the last choice is the correct one.
