Let's start with what we know:
Mary needs at least $50 to pay back her parents
Currently, she has $10, $12, and $25 in her possession. Let's add those values together and see if they equal $50 or more:
10 + 12 + 25
22 + 25 = $47
Since she only has $47, she needs $3 more to pay back her parents.
Answer:
(−a+b)(−c+d)
=(−a+b)(−c+d)
=(−a)(−c)+(−a)(d)+(b)(−c)+(b)(d)
=ac−ad−bc+bd
Answer: (C) x² - 4x + 5 = 0
<u>Step-by-step explanation:</u>
x = 2 ± i
⇒ x = 2 + i and x = 2 - i
⇒ x - (2 + i) = 0 and x - (2 - i) = 0
0 = (x - 2 - i)(x - 2 + i)
= x(x - 2 + i) -2(x - 2 + i) -i(x - 2 + i)
= x² - 2x +xi -2x + 4 <u>- 2i</u> -xi <u>+ 2i</u> - i²
= x² - 4x + 4 - i²
= x² - 4x + 4 -(-1)
= x² - 4x + 5

Answer: B
Explanation:
The slope from (0, 0) to (1, 4) is a rise of 4 and a run of 1, thus, m = 4/1 = 4
Answer:
1:3
Step-by-step explanation:
2:6 common multiple is 2 so 2:6 divide by 2 is 1:3
1210 rounded to the nearest hundred is 1200
1148 rounded to the nearest hundred is 1100
