Answer:
50
Step-by-step explanation:
find a number that is 16 less than twice a number is decrease is 84
so if i get this right it is:
84 = 2x-16?
if so we do the following:
84+16 = 2x (Move the variables to one side and the numbers to the other)
100 = 2x (simplify)
50 = x (divide each side)

The fish population in local lake is 10,000 the population increases by half every year which function represents the fish population after X years
F(x)= 10,000 parentheses (1.5)^x
Pls help it would mean a lot I’m stressing need ASAP
Answer:
5. [tex]f(x) = 10,000 (1.5)^x[/tex]
Step-by-step explanation:
==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test itInitial: 10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
--
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
--
Let's try our equation.
[tex]f(x) = 10,000 (1.5)^x[/tex]
[tex]x=2[/tex]
[tex]10,000(1.5)^2[/tex]
[tex]10,000(2.25) = 22,500[/tex]

when a number divides another number exactly the smaller number is called
Answer:
1) A number that divides another number evenly is called a factor of that number. For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16.
2) A number that divides a given set of numbers is called a common factor of the numbers.

solve the simultaneous equations 2x + 3y = 13 4x - y = -2
Answer:
Step-by-step explanation:
y = 13 /3
x = 7 /12
Answer: y=4
x=0.5
Step-by-step explanation:
Which expressions have exactly two factors? Choose ALL that apply.
A) a+ 7
B)4•n•n
C)3(b-1)
D)xy
E)m•m+8
F)2•2•2•2•2
Answer: The answer is F.
Step-by-step explanation: It’s F because the number would be multiplied equally because all of the number are multiplied by 2. The rest of them either have variables or variables with numbers in them, which looks kind of funky, so F is the answer. I hope you get it right :). Sorry, if I was late for the reply and if you already figured it out… :(.
Sketch a possible curve of f(x) given the graphs of f ‘ (x) and f’’ (x) below:
Step-by-step explanation:
Graph 1 is a parabola and has 2 x points and a turning point
meaning it has a minimum and a maximum point.
conclave points are the highs and lows, once you show this in table then you can interpreted them on a graph see the examples attached.
Graph 1 is opposite to shown interpreted conclave so instead of --c++
we write + + c - - and draw on quadrant 1 instead of quadrant 3
graph 2 is decreasing so instead of -+ c then + + it would show + - c then - - so the curve stays in quadrant 3 and 4. Also where c is we draw a 0 and say whether it is minimum or maximum point.
Both graph 1 and 2 demonstrate minimum points for their f(x) for c.
so in your workings within the table you write min as seen in red within the attachment. They wrote max, but you write min as you are in decreasing conclave fx values that reach min point c then they increase and become parabolas.
write the first five terms of the geometric sequence with the given 1st term and the common ratio.

[tex]a_n=a_1*r^{n-1}[/tex]Find the first 5 terms:

Answer:
mark me barinlest
Step-by-step explanation:
supplement angles have sum = 180, complement angles have sum = 90
180-x = 4(90-x)
180-x = 360 -4x
3x = 180
x = 180/3
x = 60
answer measure of the angle = 60
Answer:
36°Step-by-step explanation:
Supplementary angles sum to 180°.
Let the angle be x then the other angle is 4x.
Their sum is:
x + 4x = 1805x = 180x = 180/5x = 36Identify the pair of supplementary angles.

We know that, the sum of measures of supplementary angles is 180°
So, the Correct choice is :
65° and 115°because, 65° + 115° = 180°
Write an equation with variables on both sides that has no solution. Explain why it has no solution.
Answer:
4x - 5 = 2(2x + 1)
Step-by-step explanation:
4x - 5 = 2(2x + 1)
4x - 5 = 4x + 2
Then you would subtract the 4x on each side leaving you with:
-5 = 2
And obviously the value of -5 does not equal the value of 2 so therefore this equation has no solution
Hope that was what you were looking for.

What equation, in point-slope form, matches the graphed line shown?
Question 3 options:
y−5=−23(x+9)
y−6=45(x−2)
y−2=−34(x−6)
y+6=45(x+3)
Answer:
Here’s the graph
Step-by-step explanation:
The equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).
Here, we have to find the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1), we first need to find the slope (m) of the line using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
where [tex](x_1, y_1) = (6, 2) ; (x_2, y_2) = (10, -1)[/tex].
m = (-1 - 2) / (10 - 6)
m = (-3) / 4
Now that we have the slope (m), we can use the point-slope form of the equation of a line:
[tex]y - y_1 = m(x - x_1)[/tex]
Using the point (6, 2):
y - 2 = (-3/4)(x - 6)
Now, simplify the equation:
y - 2 = (-3/4)x + 9/2
Finally, move -2 to the other side to get the equation in the point-slope form (y = mx + b):
y = (-3/4)x + 9/2 + 2
y = (-3/4)x + 9/2 + 4/2
y = (-3/4)x + 13/2
So, the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).

Plot the ordered pairs from the table.
The ordered pair is plotted in the graph attached in the solution.
Given that Timony has three friends, the table shows the time taken by him to reach at his friends place and the distance of the homes of each of his friend.
We need to plot the ordered pair formed by the time and distance on the graph,
The ordered pair are:
(5, 10)
(11, 15)
(18, 20)
Plot the ordered pairs on the graph according to the given values:
The first ordered pair is (5, 10). This means that Timony took 5 units of time to reach a friend's place that is located 10 units of distance away. Mark this point on the graph.The second ordered pair is (11, 15). Timony took 11 units of time to reach a friend's place that is located 15 units of distance away. Mark this point on the graph.The third ordered pair is (18, 20). Timony took 18 units of time to reach a friend's place that is located 20 units of distance away. Mark this point on the graph.Hence the ordered pair is plotted.
