What is the slope of a line that goes through the points (3, 7) and (8, 11)

Question 4 options:

11/7

5/4

−8/3

4/5

Answer:

A.

Step-by-step explanation:

In a direct proporton, the ratio of one quantity to teh other is a constant.

Let's divide each number of crystals by each number of pounds:

7/14 = 1/2

14/28 = 1/2

21/42 = 1/2

28/56 = 1/2

The ratio of crystals to pounds is always 1:2.

This is a proportional relation.

Answer: A.

Answer:

There are 3 ways to find the slope of a line.

I'll use a simple method.

First, let's look at a random point on this line(and make sure it's close to the start of the line).

I'll choose (1,4).

Then, see how much it rises and how far it runs to another fixed point.

Though, in this case we can see that the rise is going down and the run is moving towards the right. So, the slope will be negative since the rise is negative.

You always want to confirm if it'll be a negative or positive slope and which direction the slope is guiding you to.

Now, if we go down 8 and over 3, we'll reach a fixed point of (4, -4).

Therefore, we can infer that the slope of this line will be 8/3.

Answer:

8/3

Step-by-step explanation:

rise over run, only clearly intercepts a point twice.

An increase in the use of pesticides in the same area would lead to the population of long - billed curlews decreasing.

An increase in pesticide use that kills many of the insects that long-billed curlews eat, such as grasshoppers, would likely have a negative impact on the population of long-billed curlews in the same area.

Since grasshoppers and other insects are a primary food source for long-billed curlews, a decline in insect populations due to pesticide use could lead to reduced food availability and increased competition for remaining food sources. This could lead to decreased population size and potentially even local extinctions.

Answer:

y=4

Step-by-step explanation:

The question is asking what is the value of y:

Since all lengths have a dash on them they are all equal :

So 3y = y+8

3y = y + 8

First we subtract y from both sides:

3y-y = y+8-y

2y = 8

Divide both sides by 2:

2y÷2 = 8÷2

y = 4

Answer:

Step-by-step explanation:

The question is asking you to find the value of y in a square.

A square has same length in all sides so we can achieve that:

y+8 is equal to 3y

simplifying that, we find out the answer is 4. How?

We have previously acheived that:

y+8=3*y

So we need to find y using these steps:

1. Subtract 3y from both sides:

y+8−3y=3y−3y

−2y+8=0

2. Divide both sides by -2:

y=4

The equivalent value of the sum for any value of "x" is 12x - 6

Given the sum of the expression as:

3

∑ k(2x-1)

k=0

We need to take the sum of the function at the point where k = 0 to 3

3

∑ k(2x-1) = 0(2x-1) + 1(2x - 1) + 2(2x-1) + 3(2x - 1)

k=0

3

∑ k(2x-1) = 2x-1+4x-2+6x-3

k=0

3

∑ k(2x-1) = 12x - 6

k=0

Hence the equivalent value of the sum for any value of "x" is 12x - 6

Step-by-step explanation:

4x + 32 = 5x -22

Group like terms

32 + 22 = 5x - 4x

54 = X

X = 54

Answer:

x = 54

Step-by-step explanation:

4x + 32 = 5x - 22

5x - 4x = 32 + 22

x = 54

To clarify this,

(4 x 54) + 32 = 248

(5 x 54) - 22 = 248

Step-by-step explanation:

a square has 4 identical sides.

so, when you have to "walk" around the perimeter of a square you have to go 4 times the same distance.

therefore

20 = 4×side length

side length = 20/4 = 5 in

it is a 5 in × 5 in square.

FYI a rectangle has 2 pairs of sides that are equally long inside their pair.

and so you have in this case a perimeter of

2×6 + 2×4 = 12 + 8 = 20 in

The results of preference ballots can be time-consuming to compile

The potential difficulty with preference ballots expressed in the given options is: The results of preference ballots can be time-consuming to compile.

A preference ballot is a type of ballot used in elections where voters indicate their order of preference for the candidates or options listed on the ballot.

Instead of simply selecting one option, voters rank the options in order of their preference, usually by indicating a first-choice, second-choice, and so on.

Preference ballots require more complex calculations to determine the winner, especially when there are more than two candidates. This can result in delays in announcing the results and can be time-consuming to compile.

Thus, this can result in delays in announcing the results and can be time-consuming to compile.

Answer:

116 km squared

Step-by-step explanation:

When you get crazy shapes like this, try and look for the basic ones inside (i.e. triangles, rectangles, etc.) I can find one big triangle and two rectangles, one small and one larger. Vide the attatchment for reference.

Step 1. Find the missing variables, x, y, and z

y = 2

x = 6 - 2 = 4

z = 8 + (4) + 2 = 14

Step 2. Find the area of each shape

Triangle:

Area = bh/2 = (8 x 14)/2 = 56 km sq

Big rectangle:

Area = bh = 8 x 6 = 48 km sq

Small rectangle:

Area = bh = 2 x 6 = 12 km sq

Step 3. Add all the areas together

56 + 48 + 12 = 116 km sq
