( k - 5f )( k + 5f ) + 5f( k - 5f ) =
( k - 5f )( k + 5f + 5f ) =
( k - 5f )( k + 10f );
Step-by-step explanation:
Answer: The required factored form of the given expression is [tex](k-5f)(k+10f).[/tex]
Step-by-step explanation: We are given to factor the following quadratic expression :
[tex]E=k^2+5kf-50f^2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
To factor the given expression, we need two integers with sum 5 and product -50 and those two integers are 10 and -5.
The factorization of expression (i) is as follows :
[tex]E\\\\=k^2+5kf-50f^2\\\\=k^2+10kf-5kf-50f^2\\\\=k(k+10f)-5f(k+10f)\\\\=(k-5f)(k+10f).[/tex]
Thus, the required factored form of the given expression is [tex](k-5f)(k+10f).[/tex]
what is the slope intercept form for 2x+8y=32
the slope is 1/4
and the y intercept is -4
Hope this helps
Answer:
y = -1/4x +4
Step-by-step explanation:
Slope intercept form of a line will have y on the left and mx+c on the right.
y = mx+c
Here m is the slope and c is the intercept
Any form of line can be brought to slope intercept form
Given that 2x+8y =32
We have to keep y along on left side
Hence subtract 2x first
8y =-2x+32
Now divide by 8
y = -1/4x +4 is the equation in slope intercept form

3. Edward tells Tom and his brother that any two different gym memberships will eventually have a month in which they are the same cost. So he believes any gym's membership will eventually have a month in which the cost is the same as Platinum Gym's. Describe a membership situation that will make Edward's statement untrue.
Answer:
Remember that: "Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month."
We are solving for a membership that will make Edward's statement untrue, that the gym membership fee will NOT have a month where the cost is the same.
For example, I can say that:
" Bob's Gym charges a one-time registration fee of $50, and membership is $10 a month ".
In this case, the pricing is much lower than Platinum Gym's and would not have a chance of getting the same cost in the same month.
Another example can be:
" SuperSneaker's charges a one-time registration fee of $100, and membership is $30. "
Again, the cost is much more higher than Platinum Gym's and would not have a chance of getting the same cost in the same month.

Graph the inequality y> 2x +3
Graph the inequality y> 2x +3
Solution
Step 1: To graph the inequality, we need to find a few coordinates and form the table.
Step 2: Forming the table.
Let's take x = -1 and find the value of y.
Plug in x = -1 and find the value of y.
y = 2(-1) + 3 = -2 + 3 = 1
When x = -1, the value of y is 1.
So the coordinates are (-1, 1)
Plug in x = 0 and find the value of y.
y = 2(0) + 3 = 3
The coordinates are (0, 3)
Plug in x =1 and find the value of y.
y = 2(1) + 3 = 2 + 3 = 5
The coordinates are (1, 5)

What is the slope and y-intercept of the equation 3(y − 2) + 6(x + 1) − 2 = 0? A. slope = -2, y-intercept = B. slope = 2, y-intercept = C. slope = -2, y-intercept = D. slope = 2, y-intercept = E. slope = -2, y-intercept =
The correct answer is that the slope is equal to -2 and the y-intercept is equal to 2/3.
To find this, follow the order of operations and solve for y.
3(y − 2) + 6(x + 1) − 2 = 0 ----> distribute
3y - 6 + 6x + 6 - 2 = 0 -----> combine like terms
3y + 6x - 2 = 0 -----> subtract 6x
3y - 2 = -6x -----> add 2
3y = -6x + 2 -----> divide by 3
y = -2x + 2/3
Now we can find the slope as the coefficient of x (-2) and the intercept as the constant (2/3)
Answer: The slope of the given line is -2 and y-intercept is [tex]\dfrac{2}{3}.[/tex]
Step-by-step explanation: We are given to find the slope and y-intercept of the following equation of a line:
[tex]3(y-2)+6(x+1)-2=0~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
the slope-intercept form of the equation of a line is given by
[tex]y=mx+c,[/tex] where m is the slope and c is the y-intercept of the line.
From equation (i), we have
[tex]3(y-2)+6(x+1)-2=0\\\\\Rightarrow 3y-6+6x+6-2=0\\\\\Rightarrow 3y+6x=2\\\\\Rightarrow 3y=-6x+2\\\\\Rightarrow y=-2+\dfrac{2}{3}.[/tex]
Thus, the slope of the given line is -2 and y-intercept is [tex]\dfrac{2}{3}.[/tex]
Point B has coordinates (5,2). The x-coordinate of point A is negative 7. The distance between point A and point B is 13 units. What are the possible coordinates of point A?
Final answer:
To find the possible coordinates of point A with a known x-coordinate of -7 and a distance of 13 units from point B (5, 2), we used the distance formula and found two possible y-coordinates for point A, which are -3 and 7. Hence, the possible coordinates for point A are (-7, -3) and (-7, 7).
Explanation:
The question asks for the possible coordinates of point A given that point B has coordinates (5, 2), the x-coordinate of point A is -7, and the distance between points A and B is 13 units. To find the y-coordinate of point A, we can use the distance formula d = √((x2 - x1)^2 + (y2 - y1)^2). Substituting the known values, we have:
13 = √((5 - (-7))^2 + (2 - y1)^2)
Squaring both sides of the equation, we get:
169 = (12)^2 + (2 - y1)^2
This simplifies to:
169 = 144 + (2 - y1)^2
Subtract 144 from both sides:
25 = (2 - y1)^2
Now, taking the square root of both sides, we get two possible solutions for the y-coordinate:
y1 = 2 ± 5
Thus, the possible y-coordinates of point A are -3 and 7. Therefore, the possible coordinates for point A are (-7, -3) and (-7, 7).

x=23.45
The solution to the equation [tex]2^x[/tex] = 550 is x ≈ 9.0959.
To solve the equation [tex]2^x[/tex] = 550, we need to isolate the variable 'x'. Here's the step-by-step process:
1. Take the logarithm (base 2) of both sides of the equation:
log2([tex]2^x[/tex]) = log2(550)
Using the property of logarithms, logb([tex]b^x[/tex]) = x, we have:
x = log2(550)

you roll a six sided die three times. what is the size of the sample space after those three rolls?
The answer is 216 because we will compute 6^3 = 6*6*6 = 36*6 = 216
If we had 2 dice rolled out, then it would be 6^2 = 6*6 = 36. For each die added, we multiply another 6 because the die has 6 sides.
Visually, 2 dice form a 2D table of 36 possible outcomes. Three dice form a 3D cube of possible outcomes (a 6 by 6 by 6 cube with volume 216). You can think of it like a rubix cube. Each sub-block would house a possible combo such as {2,1,7} meaning that you rolled a '2' on the first die, a '1' on the second die, and a '7' on the third die.
Note: rolling a single die 3 times will produce the same sample space as rolling three separate dice 1 time.
216 is the answer to it

Find the equation of the line that is perpendicular to y=-3/4x+1 and contains the point (9,12).
The equation of the perpendicular line is y= 4/3x
How to determine the line equation?The equation is given as:
y = -3/4x + 1
The slope of the above equation is;
m = -3/4
Let the slope of the perpendicular line be n.
So, we have:
n = -1/m
This gives
n = -1/(-3/4)
Evaluate
n = 4/3
The equation of the line is then calculated as:
y = n(x - x1) + y1
This gives
y = 4/3(x - 9) + 12
Evaluate
y= 4/3x - 12 + 12
Evaluate the like terms
y= 4/3x

The equation of the line that is perpendicular to the line y=-3/4x+1 and passes through the point (9,12) is y = 4/3x + 1.
Explanation:To solve your question, we first need to identify the slope of the given line. The equation y=-3/4x+1 is in the form y=mx+b, where m represents slope. So, the slope of the given line is -3/4.
But we require an equation that's perpendicular to this line, so its slope will be the negative reciprocal of -3/4, which is 4/3. Now, we have the slope of the new line, and we know it passes through point (9,12).
With that information, we use the point-slope formula, y - y1 = m (x - x1), where m is the slope and (x1, y1) is the point through which the line passes. Here, x1=9, y1=12 and m=4/3. Substituting these values in gives us y - 12 = 4/3 (x - 9). Simplifying yields the equation y = 4/3x + 1, which is the equation of the line that is perpendicular to the given line and passes through the point (9,12).
