Answer:

H) B= 13

Step-by-step explanation:

5 + b = 18

F) 5 + 5 = 10 so not equal to 18. It is not a solution

H) 5 + 13 = 18 it's equal . so it is the solution

G) 5 + 8 = 13 so not equal to 18. It is not a solution

J) 5 + 23 = 28 so not equal to 18. It is not a solution

On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3)

alekssr [168]

The points on the graph of (-4, 0), (-2.5, -12), and (0, -3), gives;

F(x) > 0 over the interval (-∞, -4)

<h3>Which method can be used to find the true statement?</h3>

From the description of the graph, we have;

Furthest point left of the graph = (-4, 0)

The furthest point right on the graph = (0, -3) = The maximum point

The minimum point = (-2.5, -12)

F(x) < 0 at the minimum point

The minimum point is to the right of x = -4

The point the graph crosses the y-axis = (0, -3)

Therefore;

The interval of the graph where F(x) is larger than 0 is to the left of (-4, 0), is the interval (-∞, -4)

The true statement is therefore;

F(x) > 0 over the interval (-∞, -4)

Bro I don't know how to do this and I really need help, ill give brainiest.

Answer:

Step-by-step explanation:

Because they took the correct steps to answer the equation.They also got the right answer (-2).

At the begining they added 4 to both sides (to cancel out the 4)

C would be wrong because they subtracted 4 from a negative four and this does NOT cancel it out.

Please help me I really really need help

Answer:

$B) \sqrt{2}$ ÷ $2\sqrt{5}$

Step-by-step explanation:

$A$ → $2\sqrt{5}$ ÷ $\sqrt{5}$

$= \frac{2\sqrt{5} }{\sqrt{5} }$

→ 2 is a rational number

$B)$ → $\sqrt{2}$ ÷ $2\sqrt{5}$

$=\frac{\sqrt{2} }{2\sqrt{5} }$

$=\frac{\sqrt{2} }{\sqrt{2}*\sqrt{2}*\sqrt{5} }$

$= \frac{1}{\sqrt{10} }$

↑ is irrational number

$C)$ $\frac{\pi }{2}$ ÷ $\pi$

$= \frac{\pi }{2} *\frac{1}{\pi }$

$=\frac{1}{2}$

↑ is a rational number

$D)$ $5\pi$ ÷ $\pi$

$= 5$

↑ is a rational number

So, Option B is your answer

hope it helps..

have a great day!!!
