23) Store A: y=6.30÷2
y=3.15
Store B: y=3.2
Store C: y=3.25x
y=3.25 so Store A sells the cheapest so (A) is the answer
24) the area uses half of the diameter, not the whole diameter. so the answer is 5.5pi^2 (B)
25) 1/2 × 1/2 = 1/4 × 1/2 = 1/8 (D)
26) was done correctly and (D) is the correct answer
27) 2 (x-3) +1 =19
2 (x-3) = 19 - 1
(x-3) = 18 ÷ 2
x-3 = 9
x= 9+3
x=12 (D)

Another form of (x + 1) ^2 is (x +1)(x + 1)
<u>Given </u><u>:</u><u>-</u><u> </u>
- A car travels at an average speed of 40 km/h for 0.5 hours.
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Sol</u><u>u</u><u>tion </u><u>:</u><u>-</u><u> </u>
We know that ,
→ Distance = Speed × Time
So that ,
→ Distance = 40 km/hr × 0.5 hr
→ Distance = 40km/hr × 1/2 hr
→ Distance = 20km .
<u>Hence</u><u> the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>2</u><u>0</u><u>k</u><u>m</u><u> </u><u>.</u>
<u>Answer:</u>
The answer is <u>false</u> and <u>is not</u>
<u>Explanation:</u>
Given the equation - 
Substitute x = 2 in the equation
Thus, the equation is false. When the equation is false, meaning that the coordinate x-term isn't passed by the line. (Rather say that the point is not the part of the graph.)
<u>The equation is false</u> is our first answer.
If the equation is false, that means the given value <u>is not part of the graph, thus making the x-value not the solution.</u>
