Answer:
12
Step-by-step explanation:
Given
÷
Leave the first fraction, change division to multiplication and turn the second fraction upside down, that is
× ← cancel 4 and 16 by 4
= × = = = 12
Answer:
radius is 3, center is (4,-5)
Step-by-step explanation:
when you graph this, put the first point at (4,-5) and then expand three squares up.
5x^2 - 70x + 258
= 5(x^2 - 14x) + 258
= 5[ ( x - 7)^2 - 49) + 258
= 5 (x - 7)^2 - 245 + 258
= 5(x - 7)^2 + 13
Y = 3x - 2 comparing to y = mx + c, slope m = 3
For a perpendicular line, slope is negative reciprocal = -1/3
Using point (6, 8)
y - 8 = (-1/3)(x - 6)
3y - 24 = -x + 6
3y + x = 6 + 24
3y + x = 30
