If it's possible to tell, decide if a and b are positive or negative: a-3>b-3 and b>4

Svetllana [295]

Answer:

a and b are positive

Step-by-step explanation:

We are given that

$a-3>b-3$

$b>4$

We have to find that a and b are positive or negative.

We have

$b>4$

It means b is positive and greater than 4.

$a-3>b-3$

Adding 3 on both sides

$a-3+3>b-3+3$

$a>b>4$

$\implies a>4$

Hence, a is positive and greater than 4.

Therefore, a and b are positive

What is the volume of the square pyramid with base edges 18 m and slant height 15 m

vlada-n [284]

check the picture below.

so it has a base of 18x18 and a height of that much.

$\bf \textit{volume of a pyramid}\\\\ V=\cfrac{1}{3}Bh~~ \begin{cases} B=area~of\\ \qquad its~base\\ h=height\\ ------\\ B=\stackrel{18\times 18}{324}\\ h=12 \end{cases}\implies V=\cfrac{1}{3}(324)(12)\implies V=1296$

What is the meaning os slpoe in math and please give an example for <br><br> y=2x-1;(-2,2)

alexira [117]

Slope is your 2x, so 2x over 1 meaning after you plot (-2,2) on the graph you rise 2 and go 1 to the right, or do the opposite to make the line so go down 2 and one to the left. Hope that helped.
