There you go :), hopefully this is it

4 in the third box
Step-by-step explanation:
Answer:
<h2>(x + 7)² + (y + 2)² = 49</h2>
Step-by-step explanation:
The standard form of an equation of a circle:

(h, k) - center
r - radius
We have:
center (-7, -2) → h = -7 and k = -2
radius r = 7.
Substitute:

7/9 = 42/54...when 42/54 reduces, it becomes 7/9...so this is proportional because proportions are nothing but equivalent fractions.
u could also check it this way...
12/21 = 15/24
cross multiply
(21)(15) = (12)(24)
315 = 288.....these do not equal and are therefore, not proportionate
440/4 = 300/3
110 = 100....not equal, so not proportionate
120/5 = 88/4
24 = 22.....not proportionate
66/82 = 99/123
0.804 = 0.804.......these are proportional
68/172 = 43/123
0.395 = 0.349......nope, not proportional
<u>Answer:</u>
The horizontal number line that could be used to show number of centimeters of ribbon Hilary unraveled is 3cm to 4.5cm
<u>Explanation:</u>
Given that Hilary has already unraveled 3.0 centimeters of ribbon and then continues to unravel 1.5 more.
So starting will be 3.0 cm and maximum ribbon unravelled will be equal to 4.5cm so the horizontal number line that could be used would be from 3cm to 4.5cm including both fractional and integral values.
