15 is just 10% of a number. 10% is 1/10 of a hundred percent, so to find the 100%, multiply 15 by 10 and get: 150

150. It is 150 because you take 150 divided by 100 equal 1.5 and then you times it by ten and it is 15.

Solve the inequality. –1/4x – 8 < 3/4

Firlakuza [10]

Step-by-step explanation:

Step 1: Add 8 to both sides

$-\frac{1}{4}x - 8 + 8 < \frac{3}{4} + 8$

$-\frac{1}{4}x < \frac{35}{4}$

Step 2: Multiply both sides by -4

$-\frac{1}{4}x * -\frac{4}{1} < \frac{35}{4} * -\frac{4}{1}$

$x > -35$

Answer: $x > -35$

True or false:

kiruha [24]

Not really, If you use the Pythagorean theorem on all problems related to distance.. You won't always be able to solve it. It depends on the numbers.

So, false.

Step-by-step explanation:

Step 1: Define

9m - m + 3 = -2(m + 1)

Step 2: Solve for m

Combine like terms: 8m + 3 = -2(m + 1)
Distribute -2: 8m + 3 = -2m - 2
Add 2m on both sides: 10m + 3 = -2
Isolate m term: 10m = -5
Isolate m: m = -1/2

The polynomial equation x cubed + x squared = negative 9 x minus 9 has complex roots plus-or-minus 3 i. What is the other root?

Ymorist [56]

Answer:

-1,3i,-3i

Step-by-step explanation:

X^3+x^2=-9x-9

x^3+x^2+9x+9=0

x^2(x+1)+9(x+1)=0 factorize by taking x+1 common factor

(x+1)(x^2+9)=0

x+1=0 then x=-1

(x^2+9)=0 then x=+ 0r - 3i
