Answer:
B
Step-by-step explanation:
3 is too high up to be in the middle of the line, so the y value must be and this eliminates C and D as possible answers. -7 is too far back on the y axis, so this eliminates A. We are left with B.
Answer:Diameter is 2 Radii=2r
Step-by-step explanation:Diameter contains 2 sets of radius called Radii
X 2 − 10 x − 18 y − 2 = 0 Explanation: for any point ( x , y ) on the parabola the distance from ( x , y ) to the focus and directrix are equal ⇒ √ ( x − 5 ) 2 + ( y − 3 ) 2 = | y + 6 | squaring both sides ( x − 5 ) 2 + ( y − 3 ) 2 = ( y + 6 ) 2 ⇒ x 2 − 10 x + 25 + y 2 − 6 y + 9 = y 2 + 12 y + 36 ⇒ x 2 − 10 x − 18 y − 2 = 0
Answer:
y = 3x + 4
Step-by-step explanation:
y = mx + c where m is the slope and c is the y intercept.
Slope =
Slope (taken from points (0, 4) and (1, 7)) =
= 3
y-intercept = 4
Equation: y = 3x + 4
20 because 1/5 of 25 is 5 so five from twenty-five would be 20!
