Step-by-step explanation:

$\frac{-5+2 \iota}{1+7 \iota} \times \frac{1-7 \iota}{1-7 \iota} \\=\frac{-5+35 \iota+2 \iota-14 \iota^2}{1-49 \iota^2} \\=\frac{-5+37 \iota-14(-1)}{1-49(-1)} \\=\frac{9+37 \iota}{50} \\=\frac{9}{50} +\frac{37}{50} \iota$

domain is x²≤36

|x|≤6

What is 4 3/4 + 7/8 showing all work

Mekhanik [1.2K]

$4 \frac{3}{4} + \frac{7}{8}$

Convert mixed numbers to improper fractions

$= \frac{19}{4} + \frac{7}{8}$

Find de LCD for 4 and 8 :

Factor each denominator into its primes:

$4 = 2^2
$

$8 = 2^3$

Find the least common denominator $2^3 = 8$

Adjust fractions based on the LCD :

$\frac{19*2}{8} + \frac{7}{8}$

Since the denominators are equal , combine the fractions:

$\frac{2*19+7}{8}$

$\frac{38+7}{8}$

$= \frac{45}{8}$

Therefore:

Convert improper fractions to mixed numbers

$= 5 \frac{5}{8}$

hope this helps!

Cameron is playing 9 holes of golf. He needs to score a total of at most 13 over par on the last four holes to beat his best gol

Genrish500 [490]

Cameron does beat his best score. He scores 7 and 8 over par, as well as 3 under par twice. This makes him have 7 + 8 or 15 over par and 3 + 3 or 6 under par. 15 - 6 = 9, which is under 13, his current best score.
