Answer:
(4x - 3)(x-2) = 0
Step-by-step explanation:
4x² - 11x + 6 = 0
To factorize this equation,
-11
4x6
These numbers are the key to the solution:
find two numbers whose sum is -11 and the product is + 24 (4 x 6)
So, the numbers are -3 and -8
4x² - 8x - 3x + 6 = 0
4x(x -2) - 3(x - 2) = 0
(4x - 3)(x-2) = 0
Answer:
(4x - 3)(x - 2) = 0

A club had some money to purchase new chairs. After buying 355 chairs at $199 each, there was $1,068 remaining. How much money did the club have at first? *
Answer:
$71713
Step-by-step explanation:
If each chair cost $199 then multiple 199 by 355
[tex]199*355= 70645[/tex]
If they still have 1068 then add that into the sum
[tex]70645+1068=71713[/tex]
So your answer is $71713
Answer: $71,713
Step-by-step explanation:
First you would multiply 355 by 199 to get 70,645. Next you would add the remainder of what they had, $1,068, and get the answer. hope this helps.
Math question please help
A table is on sale for 25% off. The original price of the table is $132.00.
What is the discounted price of the table?
$128.00
$33.00
$107.00
$99.00
Answer:
99%
Step-by-step explanation:
25% of 132 is 33 so 132-33 is $99
Answer: 99
Step-by-step explanation:
turn 25% into a decimal which is .25 and multiply it by 132 to get 33. Thats how much 25% of 132 is so you subtract it to get how much it costs with the sale price.

Answer:
[tex]m\angle{QPR}}=40[/tex]
Step-by-step explanation:
We are given that lines [tex]PQ[/tex] and [tex]PS[/tex] are perpendicular lines, meaning they intersect and each other, and as a result, create a right angle ([tex]90[/tex]).
With that being said, let's add the expressions representative of the two angles and set them equal to [tex]90[/tex] degrees:
[tex]7x-9+4x+22=90[/tex]
Combine like terms:
[tex]11x+13=90[/tex]
Subtract 13 from both sides of the equation:
[tex]11x=77[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]11[/tex]:
[tex]x=7[/tex]
Now, let's substitute this into the expression of angle [tex]QPR[/tex]:
[tex]7(7)-9[/tex]
[tex]=40[/tex]
_
You can check your work by substituting the value of [tex]x[/tex] into the other expression, and then adding that answer with our initial answer to make sure it equals [tex]90[/tex] degrees:
[tex]4(7)+22[/tex]
[tex]28+22=50[/tex]
[tex]40+50=90[/tex]
Since the two angles add up to 90, our answer is correct!

Find the equation for a line in slope-intercept form that goes through the points (-3, -2) and (3, 16)
Answer:
y = 3x+7
Step-by-step explanation:
The standard form of equation in slope-intercept form is:
y = mx+c
m is the slope
c is the intercept
Given the coordinates (-3, -2) and (3, 16)
Get the slope;
Slope = ∆y/∆x
Slope = y2-y1/x2-x1
Slope = 16-(-2)/3-(-3)
Slope = 16+2/3+3
Slope = 18/6
Slope = 3
Get the Intercept
Substitute one of the points in the formula:
Using the coordinate (-3, -2)
y = mx+c
-2 = 3(-3)+c
-2 = -9 + C
c = -2+9
c = 7
Get the equation of the line by substituting m and c into the equation y = mx+c
y = 3x+7

How much was the initial website fee? (from this equation)
Answer:
y= .75x + 3.75
Step-by-step explanation:
1. Distribute x:
Original Equation= y-2.25=.75(x-8)
So you just do .75 times x and .75 times -8= .75x - 6
2. Isolate the y Variable:
Add 2.25 to both sides. So -6 + 2.25= 3.75
Now you have left y= .75x + 3.75

A popular restaurant advertises that it delivers its orders within 30 minutes. Suppose the average delivery time for one store is 27 minutes with a standard deviation of three minutes. One particular order delivery has a z-score of –2.15. Which of the following statements is not a correct interpretation?
A.The delivery time was 2.15 standard deviations below the average delivery time.
B.The delivery time was less than the average delivery time by 2.15 standard deviations.
C.The delivery time was faster than the average delivery time by 2.15 standard deviations.
D.The delivery time was slower than the average delivery time by 2.15 standard deviations.
Answer: B. The delivery time was less than the average delivery time by 2.15 standard deviations.
Step-by-step explanation:
Given: A popular restaurant advertises that it delivers its orders within 30 minutes.
Suppose the average delivery time for one store is 27 minutes with a standard deviation of 3 minutes.
z-score value represents the number of standard deviations is the data value is far from mean.
Here, z-score = -2.15 which clearly indicates that the delivery time was 2.15 standard deviations below( '-' sign suggest value is below mean) the average delivery time.
Hence, the correct option is B.
Answer:
B
Step-by-step explanation:
