4 0

Answer:

(0,0) is among the solutions

Step-by-step explanation:

The given inequality is $y\ge4x-5$

A solution to this inequality is any ordered pair that satisfies the inequality.

Let us check for x=0 and y=0

We substitute to get:

$0\ge4*0-5$

$0\ge-5$ ....This is true.

Therefore (0,0) is a solution to the given inequality.

There are infinitely many solutions.

Find the length of the base of a square pyramid if the volume is 128 cubic inches and has a height of 6 inches

Len [333]

Answer: a = 8

Step-by-step explanation:

Volume of a square based pyramid is given as

$\frac{a^{2}h }{3}$ .

where a is the length of the side and h is the height.

Substituting into the formula , we have

V = $\frac{a^{2}h }{3}$

128 = $a^{2}h$ /3

384= $a^{2}$ X 6

Divide through by 6

384/6 = $a^{2}$

64 = $a^{2}$

Therefore :

a = $\sqrt{\frac{64}{1} }$

a = 8

Which represents a side length of a square that has an area of 450 square inches?

vovikov84 [41]

<span>I have been a high school/jr high math teacher for the past 13 years. I am happy to explain how to proceed with this problem.
A square is a figure where ALL sides are exactly the same. The find the area of the square you would multiply one side times another side. You would be multiplying a number times itself. So if you already have the area, you would take the square root to find your answer. When you do, you end up with 21.21 square inches rounded to the nearest hundredth.</span>

Solve: - 12 = -12(x + 2)

Fofino [41]

Answer:

x=-1

Step-by-step explanation:

-12=-12(x+12)

multiply -12 and x which equals -12x

multiply -12 and 2 which equals -24

the resulting equation is -12=-12x-24

add 24 on both sides of the equation----> equals -12x=12

divide -12 on both sides of equation

x=-1
