y = -75x + 640
Step-by-step explanation:
y = 640 - 75x ....................where y is how much money she has left and x the number of weeks
Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 7)² + (y - 5)² = 16 ← is in standard form
with centre = (- 7, 5 ) and r =
= 4 → B
divide
4915/72 = 68.2638
so $68.26 per stock is the unit rate
BC also has length 12 because arcs DC and CE add up to 117 degrees in measure, so that arc DE is congruent to arc BC, and the chords DE and BC that respectively intercept these arcs must also be congruent.
