Which linear equality will not have a shared solution set with the graphed linear inequality? y >2/5 x + 2 y <-5/2 x – 7 y >-2/5 x – 5 y < 5/2x + 2

Answers

The linear equality y < -5/2x - 7 will not have a shared solution set with y > 2/5x + 2.

To determine which linear equality will not have a shared solution set with the graphed linear inequality y > 2/5x + 2, you need to check the slopes of the lines involved.

The linear inequality y > 2/5x + 2 has a slope of 2/5.

Now, let's examine the given linear equalities and their slopes:

y < -5/2x - 7 has a slope of -5/2.

y > -2/5x - 5 has a slope of -2/5.

y < 5/2x + 2 has a slope of 5/2.

The linear equality that will not have a shared solution set with the graphed linear inequality y > 2/5x + 2 is the one with the opposite (negative reciprocal) slope, which is the one that has a slope of -5/2.

Flora has c coats. She has 4 more shirts than half of the amount of coats.If c represents the number of coats Flora has, write the expression that can be used to find how many shirts she has?

Answers

The expression would be (1/2)c+4 because it is half the amount of coats and there are 4 more shirts, indicating addition.

A pole that is 3.4m tall casts a shadow that is 1.03m long. At the same time, a nearby building casts a shadow that is 41.5mlong. How tall is the building?

Answers

I got that the building is 136.9902912...(nonterminating) meters tall. Or you could round that to 137m tall. I got that by setting up ratios of the height and the shadows, then cross multiplying.

How many points do you need in order to name a ray ?

Answers

Answer:

2 points are needed to name a ray.

Step-by-step explanation:

A ray is defined as a portion of a line, because it begans at a specific point while line doesn't begin or end at a specific point.

The way to define a ray is using two points, the initial where the ray begins and the second indicates the orientation.

Therefore, there are needed 2 points to name a ray.
oou only need two points. Hope this helps!
