Answer:
21
Explanation:
To solve this problem, you substitute in the 5 for the x creating this equation: f(5)=6+3(5).
f(5)=15+6
f(5)=21
I need help on this question I don’t get what it’s asking what so ever
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

Use a graphing calculator to sketch the graph of the quadratic equation, and then state the domain and range
y = x + 2x - 5
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.

The equivalent value of the sum for any value of "x" is 12x - 6
How to find the sum of functions?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

The measure of the vertex angle is
degrees.
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

Writing Expressions and Equations the product of 6 and 11
Answer:
The product of 6 and 11 is 66
But what is the reason for this?The product of two or more numbers is the same as multiplying those numbers together. The product will always be the result.
[tex]6 * 11 = 66~or~66 / 11 = 6[/tex]
Notice how the division problem is just the multiplication problem backwards, for the purpose of better understanding.

A road is 4350m long, correct to the nearest 10 metres. Kirsty drove along the road in 205 seconds, correct to the nearest 5 seconds.
The average speed limit for the road is 80km/h
Could kirsty’s average speed have been greater than 80km/h?
Kirsty's Average speed is not greater than 80km/h
What is speed?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.

Long-billed curlews eat many different kinds of insects, including grasshoppers, as a source of food. It has been shown that pesticide use kills many of these insects. How would you expect an increase in pesticide use to affect to the population of long-billed curlews in the same area
An increase in the use of pesticides in the same area would lead to the population of long - billed curlews decreasing.
How will the population of long-billed curlews be affected by pesticides ?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.

If LOVE is a square with LO = 2x + 3 and OV = 9, what is the value of x?
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,
9=2x+3
9-3=2x
6=2x

What is preference ballot?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.
