Solve for x.

px + qx = ax (p + q) = ax = a / (p + q)2.1.2
2x² - 5x + 2 = 02x² - 4x - x + 2 = 02x(x - 2) - 1(x - 2) = 0(2x - 1)(x - 2) = 0x = 1/2, 22.1.3

Answer:
x = a/(p+q)
x = 2 or x = 1/2
x = -2
m≤ -1 or m<4
-1 , 0 , 1 , 2 and 3.....................since : -1 ≥ m < 4.
x = -3 and y = 9.
Step-by-step explanation:
The first one is just making x to be the subject of the formula by factorising p and q. Then dividing both sides by (p + q).
px + qx = a........................... x (p + q) = a............divide sides by ( p+q) to get the expression.
Solve quadratically for the second one.
For the third one, apply the laws of indices to work out.
32 = ( 1/2)^-5..............so, ( 1/2)^3x + 1 = ( 1/2)^-5.......Drop the base numbers since they are common.
3x + 1 = -5.........then solve to get x as -2.
For the fourth one, we solve for m by separating it into 2.
the first one is: -11 ≤ 3m - 8.
the second one: 3m - 8 < 4
then solve like a normal equation but maintain the inequality signs.
For the integral values, you'll get them from the answers because the answers are a range

There are 12 tomato plants for which 75 < h < 85
One of the tomato plants is selected at random.
Find an estimate for the probability that this tomato plant has a height greater than
82.5 cm
Answers
The histogram is an illustration of a discrete probability, and the probability that this tomato plant has a height greater than 82.5 cm is 0.40
How to estimate the probability?The histogram is given such that the distribution of the plant heights is:
75 < h ≤ 85
To estimate the probability that this tomato plant has a height greater than 82.5 cm, we make use of the following formula
P(h >82.5) = P(85)
From the histogram, we have:
P(85) = 24/60
Evaluate
P(85) = 0.40
Substitute P(85) = 0.4 in P(h >82.5) = P(85)
P(h >82.5) = 0.40
Hence, the estimated probability is 0.40

Answers
Answer:
[tex]\displaystyle \large{y=x^2-2x-3}[/tex]
Step-by-step explanation:
The given points are (-1,0) and (3,0) to find an equation of parabola. Notice that they say or the given points are x-intercepts, which means they make it easier for us to find an equation of parabola using these x-intercepts.
Quick Note:
x-intercepts are simply the roots or solutions of quadratic equation, so if our root is x = -2 then we can write as (-2,0) and write back to x+2=0.So what we are going to do is to write the roots’ equation back as [tex]\displaystyle \large{x+\alpha =0}[/tex]
Our points or roots are given, therefore:
If x = -1 then x+1=0
If x = 3 then x-3=0
Then multiply x+1 with x-3 because if (x-1)(x+3)=0 then x-1=0 or x+3=0:
[tex]\displaystyle \large{(x+1)(x-3)=0}[/tex]
Convert 0 to y since we want to find a function:
[tex]\displaystyle \large{(x+1)(x-3)=y}\\\displaystyle \large{y=(x+1)(x-3)}[/tex]
Expand the expressions in and simplify to standard form:
[tex]\displaystyle \large{y=x^2-3x+x-3}\\\displaystyle \large{y=x^2-2x-3}[/tex]
Therefore, the equation is [tex]\displaystyle \large{y=x^2-2x-3}[/tex]

Answer:
300-400
Step-by-step explanation:
The first step is finding the total of the data we have. So, we take 5 + 10 + 15 + 20 + 25 + 15 + 10 which equals 80.
The median is the middle point of all the data. If it's an odd number, you can calculate the median with the equation (n+1) / 2, plugging in the total amount of data for n.
When it's an even number though, there is no one middle point since the data splits evenly in 2, so we have to use 2 equations: n/2 & (n/2) + 1. Then, we find the average of those two data points. (Although, you don't have to do that for this particular question).
When we plug 80 in for n in both of these equations, we get 40 and 41.
To where this is in the question, we have to count up from the bottom of the chart. 1-5 is below 100, 6-15 is 100-200, 16-30 is 200-300, and 31-50 is 300-400.
Since 40 and 41 are between 31 and 50, the answer is 300-400.

If RV=w and SU=w–30, what is the value of w?
Answers
Answer:
w = 60
Step-by-step explanation:
the midsegment SU is half the measure of side RV , then
SU = [tex]\frac{1}{2}[/tex] RV , so
w - 30 = [tex]\frac{1}{2}[/tex] w ( multiply through by 2 to clear the fraction )
2w - 60 = w ( subtract w from both sides )
w - 60 = 0 ( add 60 to both sides )

For 12:
8g < 4
8(12) < 4
96 < 4
This statemen is false, because 96 is NOT less than 4
For 2.5:
8g < 4
8(2.5) < 4
20 < 4
This statemen is false, because 20 is NOT less than 4
For 4:
8g < 4
8(4) < 4

The semi-annual payment is $1662.47
What will be the semi annual payment?Given : A 3 year loan of $8,561 at 9.1% compounded semi-annually.
We have to determine the semi annual payment.
We know,
[tex]P=\dfrac{PV.r}{1-(1+r)^{-n}}[/tex]
Where PV is present value of loan.
r is rate of interest
n is time period.
Given loan is calculated semi annually,
So PV = $ 8561
r=9.1 % =9.1/200
and time period is 3 years = 6 number of period as semi annually.
Thus, Substitute,
We get,
[tex]P=\dfrac{8561(\dfrac{9.1}{200})}{1-(1+\dfrac{9.1}{200})^{-6}}[/tex]
[tex]P=1662.47[/tex]

The interior angles of a simple quadrilateral ABCD add up to 360 degrees of arc.
Answer:
Angle x = 40°
Step-by-step explanation:
All angles of any quadrilateral sum up to 360°.
So here, already measure of 3 angles are given.
So if we add up all angles + Angle x then it sums up to 360°.
So, the following steps will lead you to the answer:
73° + 157° + 90° + Angle x = 360°
(Now add up the measure of the three given angles)
320° + Angle x = 360°
(Now, through transposition moves 320° to the RHS) (Remember when transposing the signs change)
Angle x = 360° - 320°
Finally,
Angle x = 40°

Mary will receive 1512.4931 more Yen if she makes her trade on the day with the most favorable exchange rate than that of the least favorable exchange rate.
What is the exchange rate?It is the factor by which currency conversion of two countries is done.

So, Mary will receive on Friday= 311.75 x 92.7120 x 94/100
Mary will receive on Friday(a)=27168.788 Yen
The least Favorable day is Wednesday because the exchange rate on Wednesday is the least.
So, Mary will receive on Wednesday= 311.75 x 87.5507 x 94/100
So, Mary will receive on Wednesday(b)= 25,656.2949 Yen
Difference between (a) and (b) = 1512.4931 Yen
