The answer is A because the phrase " no more than" stands for the symbol "less than or equal to", and "the sum of the square if the number and 9" stands for the number squared and then added to nine (x + 9)2.

Answer:

Option A is correct

x+20 \leq x^2+9

Step-by-step explanation:

Let the number be x.

As per the statement:

The sum of a number and 20 is no more than the sum of the square of the number and 9.

"sum of a number and 20" translated to x + 20

"no more than" means \leq

"sum of the square of the number and 9" translated to x^2+9

then;

x+20 \leq x^2+9

Therefore, the following inequalities can be used to determine this unknown number is, x+20 \leq x^2+9

I need #2, #3, #4, #7, and #8.<br> but do as much as you can pls thanks !
kifflom [539]

Answer:

See explanation.

Step-by-step explanation:

2) Your written answer is correct, y = x +4

3) Slope of perpendicular line: 5/2

y=mx+b

4 = (5/2)(4) + b

4 = 10 + b

b = -6

So, y=(5/2)x - 6

4) Slope of perpendicular line: 1

y=mx+b

5 = (1)(4) + b

5 = 4 + b

b = 1

So, y = x + 1

7) Slope of perpendicular line: 3/4

y=mx+b

4 = (3/4)(4) + b

4 = 3 + b

b = 1

So, y = (3/4)x + 1

8) Slope of perpendicular line: 1/4

y=mx+b

-2 = (1/4)(0) + b

b = -2

So, y = (1/4)x - 2
