Answer:
Inside the circle, a distance of from the center of the circle.
Step-by-step explanation:
Center of circle is at (0,0)
One point of the circle is at (0,)
Since the only known point is in the y-axis, the radius of the circle must be .
= 6.164
So the point (-5,-3) is still inside the circle as the distance from point (-5,-3) to the center of the circle is or which is less than the radius of the circle.
Answer:
Step-by-step explanation:
step 1. convert the total value into pennies, so $1.29 = 129 cents
step 2. let x = number of 18 cent stamps
step 3. then, the number of 15 cent stamps will be 3x - 4
step 4. our equation will be 18x + 15(3x - 4) = 129
step 5. expanding, we get 18x + 45x - 60 = 129
step 6. combining, we get 63x = 189
step 7. solving, x = 3 then number of 18 cent stamps
step 8. then 3x - 4 = 9 - 4 = 5 the number of 15 cent stamps
Proof: (18 x 3) + (15 x 5) = 54 + 75 = 129
272.05?? Pretty sure but I might be wrong because It’s 2 am rn so
Answer:
the x means up and some time's left while y means down and right
