Answer:
3/ax-4=20
first add 4 to both sides
3/ax=20+4
multiply by a/3
24a/3
so x=8a
Answer: 1/8a
Step-by-step explanation: add 4 to both sides first, which will give you 3/ax = 24. Now multiply both sides by ax/3 to get rid of the 3/ax, which will then give you 1 = 24 * ax/3, which equals to 1 = 24ax/3. This can be simplified further and you'll get 1 = 8ax. now divide both sides by 8a to isolate x, you will end up with 1/8a = x.

The slope of the line which passes through the points (4, 18) and (6x, 2k) is (k - 9)/(3x - 2).
According to the given question.
A line passes through points (4, 18) and (6x,2k).
Which means we have two points (4, 18) and (6x,2k).
As we know that, the slope of a line is the ratio of the amount that y increases as x increases some amount.And the slope formula is m=(y2-y1)/(x2-x1) if a lines passes through the point (x2, y2) and (x1, y1).
Therefore, the slope of the line which passes through the points (4, 18) and (6x,2k)
= 2k - 18/ 6x - 4
= 2[k - 9]/2[3x - 2]
= (k-9)/(3x - 2)
Hence, the slope of the line which passes through the points (4, 18) and (6x, 2k) is (k - 9)/(3x - 2).

On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal at y = negative 1. Everything above the line is shaded. The second dashed line has a negative slope and goes through (negative 2, 1) and (0, 0). Everything below the line is shaded.
A system of inequalities can be used to determine the depth of a toy, in meters, in a pool depending on the time, in seconds, since it was dropped. Which constraint could be part of the scenario?
Using a linear function, one constraint on the inequality is given by:
y < -0.5x.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points, the slope is given by change in y divided by change in x.
For the line in the inequality, the points are:
(-2,1) and (0,0).
Hence the slope is given by:
m = (0 - 1)/(0 - (-2)) = -1/2 = -0.5.
Hence:
y = -0.5x + b.
When x = 0, y = 0, meaning that the y-intercept is of b = 0, and:
y = -0.5x.
Everything below the line is shaded, meaning that the values of y that are less than the line are shaded, and the inequality is:
y < -0.5x.
The inequality is only less, not less or equal, because the line is dashed and not solid.

b. What product is missing from the grid?
What is the missing number from the grip I need help
The four factors were used to create this Product Game board are {2, 3, 5, 7} and the product missing from the grid is 25
To see what are factors are used in the given list, we just need to write each of the numbers, as a product of prime factors such as 2, 3, 5, 7 .
9 = 3* 3
15 = 3 *5
18 = 3 *2*3
21 = 7*3
30 = 5*3*2
35 = 7*5
36 = 3*3*2*2
42 = 2*3*7
49 = 7*7
As we can see, the 4 factors used to product the numbers in the given list are {2, 3, 5, 7}
for the second part that is to find the missing number between 21 and thirty we first need to write all the numbers between 21 and thirty and check which number is having the only factors of at least one of (2,3,5,7)
the numbers are 22 , 23 ,24, 25 ,26 ,27 ,28, 29
After checking the missing number is 25(5*5) because there has to be at least 4 products who have same factor and 5 is the factor who has appeared only three times

a boy throws a baseball across a field. the ball reaches its maximum height, 18 meters, after 1 second. after approximately 2.3 seconds, the ball lands on the ground. the ball’s motion can be modeled using the function f(x)
The height of the ball after 1.5 seconds is 15.5 meters so option (C) will be correct.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the function as the height of ball f(x) and time x
f(x) = -10x² + 20x + 8
At x = 1.5
f(1.5) = -10(1.5)² + 20(1.5) + 8
f(1.5) = 15.5
Hence "The height of the ball after 1.5 seconds is 15.5 meters".

Salma drives from A to C.
She drives for 30 minutes at an average speed of 62 miles per hour.
Work out the distance AD.
Not drawn
accurately
The distance AD is 49 miles.
As per the given values of speed and time, we will calculate the distance AC. Firstly equalising the units.
As per the known fact, 60 minutes = 1 hour
30 minutes = (1/60)×30
30 minutes = 0.5 hour
Now, speed, distance and time are related as -
Speed = distance ÷ time
Distance = speed × time
Distance = 62 × 0.5
Distance = 31 miles
So, AC = 31 miles and BC = 25 miles.
Therefore, AB = AC - BC
AB = 31 - 25
AB = 6 miles
The distance AD = AC + CD
AD = 31 + 3 × AB
AD = 31 + 3 × 6
AD = 31 + 18
AD = 49 miles
Therefore, the distance between AD is 49 miles.

Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.
The simple interest for $900 at an interest rate of 6% is $108.
What is simple interest?Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.
We have,
Principal = $900
Rate of interest = 6%
Time = 2 years.
Remember that time should always be in years.
The formula for simple interest is given by:
SI = PRT / 100
Where,
P = principal
R = rate of interest
T = Number of years
So,
SI = 900 x 6 x 2 / 100
SI = $108
Thus the simple interest for $900 at an interest rate of 6% is $108.
