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

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.

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

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.

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:

x = 50

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

Since triangle ABC is an isosceles triangle the measure of <c is also = x

x + x + x + 30 = 180 add like terms

3x + 30 = 180 subtract 30 from both sides

3x = 150 divide both sides by 3

x = 50

Kirsty's Average speed is not greater than 80km/h

Speed is the rate of change of distance.

Analysis:

length of road = 4350m = 4350/1000km = 435/100km

time taken = 205 seconds = 205/3600 hour

Her Speed = 435/100 ÷ 205/3600 = 435/100 x 3600/205 = 76.4km/h

In conclusion, Kirsty's average speed is not greater than 80km/h.

Answer:

3

Step-by-step explanation:

2x+3=9

You have to get rid of the 3 and the operation that is happening between the 2x and 3 is addition so you must do the opposite which is subtract .

2x+3-3=9-3

Cross out the 3's . What you do to one side do it to the other side .So subtract 3 from both sides .

2x÷2=6÷2

Now to get rid of the 2 you divide because the operation that is happening between the 2 and x is multiplication.And what u do to one side do it to the other . So

x= 3

Hope this helps and sorry if you don't under the explanation

Step-by-step explanation:

LO = 2x + 3 and OV = 9,

Answer:

d. D: allreal numbers

R: y>= -6

Step-by-step explanation:

You are allowed to use a graphing calculator to see the graph. See image.

This curve is a parabola. Upward and downward opening parabolas have a domain of all real numbers. Any x can be found on the graph and/or any x can be used in the equation without limit. That's "all real numbers"

See the graph does not exist below -6. Range is all the y's on the graph and/or all the possible y's the equation will spit out. Here we can clearly see the graph only exists from -6 and up. Range is y>= -6.
