Answer:

The points that verify the system of inequalities are:

point E, pointF, and point G.

Step-by-step explanation:

Please see the attached image that illustrates the boundary lines in your system of inequalities.

The boundary line for the inequality 2x+y is depicted in green, while the boundary line for the inequality 2x-4y>8 is depicted in red.

By solving for y in each inequality, we understand which half-plane should be considered for the inequality:

First inequality (green boundary line) :

2x+y

This means that we are to consider the points below the green boundary line.

Second inequality (red boundary line) :

2x-4y >8\\2x-8>4y\\y

This means we have to consider the points below the red boundary line.

Recall as well that both conditions we arrived at have to be satisfied by the points that are solutions of both inequalities.

From the image, we can see that there are only three points that reside at the same time below the green and the red boundary lines. These points are: point E, pointF, and point G.

On the other hand, we have two points that lie on a boundary line (point J and H), but they should be ignored, since the system of inequalities contain just inequality symbols < or >, and not the "equal" sign.

Given the equation 5+x-12=x-7:
yanalaym [24]
<h2>(-∞,∞) </h2>

Step-by-step explanation:

PART A:

given 5+x-12=x-7

5+x-12=x-7\\x-7=x-7\\x=x\\

This is true for all values of x.

So,x∈(-∞,+∞)

PART B:

When x=4,left hand side=5+4-12=-3

right hand side=4-7=-3

so,left hand side =right hand side

When x=0,left hand side=5+0-12=-7

right hand side=0-7=-7

so,left hand side =right hand side

When x=5,left hand side=5+5-12=-2

right hand side=5-7=-2

so,left hand side =right hand side

a five inch bamboo shoot doubles in height every three days. If the equation y=ab to the x power, where x represents the number
PtichkaEL [24]
This question was once asked before so I will put it here.

The correct answer for the question that is being presented above is this one: "x = 2; a = 5; b = 3" A 5 inch tall bamboo shoot doubles in height every 3 days. If the equation y=ab^x, where x is the number of doubling periods, represents the height of the bamboo shoot.

Which triangle would be most helpful in finding the distance between the points (-4, 3) and (1,-2) on the coordinate
earnstyle [38]

Answer:

On a coordinate plane, a triangle has points (negative 4, 3), (negative 4, negative 2), (1, negative 2).

Step-by-step explanation:

The points (-4,3), (1,2) and (-4, -2) would form a right triangle when graphed and connected by lines.

(-4,3), (1,2) and (1,3) would also work as well

What is the value expression 8+24 divided by (2 times 6) - 4
Sphinxa [80]

Answer:

6

Step-by-step explanation:

Given mixed operations there is a particular order that must be followed.

Using the order set out in the acronym PEMDAS

P - Parenthesis ( brackets ), E- Exponents ( powers ), M - Multiplication, D - Division, A- Addition, S - Subtraction

8 + 24 ÷ (2 × 6) - 4

= 8 + 24 ÷ 12 - 4 ← parenthesis

= 8 + 2 - 4 ← division

= 10 - 4 ← addition

= 6 ← subtraction
