3x + 2 3 y - 15 < 0 The point (x, 9) is a solution for the inequality shown. What is a possible value for x?
love history [14]

Answer:

x is any number less than -64; i.e. -66

Step-by-step explanation:

Inequality

3x + 23y - 15 < 0

where point (x,9) satisfies this

Substitute 9 for y

3x + 23(9) - 15 < 0

3x + 207 - 15 < 0

3x + 192 < 0       Take away 192 from both sides

3x < -192             Divide both sides by 3 to isolate x

x < -64


Check:

3(-64) + 23(9) -15 < 0

-192 + 207 - 15 < 0

-192 + 192 < 0

Therefore x must be less that -64 to satisfy the point (x, 9) in this inequality.

Write a polynomial function with zeros -3,5,8​
klemol [59]

Answer:

x^3-10x^2+x+120

Step-by-step explanation:

Assuming you mean roots -3, 5, 8

These happen when we have (x+3)(x-5)(x-8)=0

Expand this

(x^2-2x-15)(x-8)=0

=x^3-2x^2-15x-8x^2+16x+120

=x^3-10x^2+x+120

Given that these triangles are similar, what is the perimeter of triangle PQR? Show your work.
dimaraw [331]

Answer:

24

Step-by-step explanation:

I use the Pythagoras theorem.

\sqrt{a^{2} +b^{2} } =c^{2}

4^{2}{x}6^{2} = c^{2}

16 x 36= 576

\sqrt{576} = 24
