Let's solve for p.
px=x^2−7x
Step 1: Divide both sides by x.
px/x=x^2−7x/p
=x−7

The value of p (x-1) is;
⇒ [tex]p(x - 1) = x^{2} -9x+8[/tex]
Here,
The function is given as;
[tex]p(x) = x^{2} -7x[/tex]
We have to find the value of p (x - 1).
What are the polynomials function?
A function that involves only non negative integer powers is called polynomial of function.
Now,
The function is given as;
[tex]p(x) = x^{2} -7x[/tex]
To find the value of p (x- 1), we can substitute x-1 in place of x, we get;
[tex]p(x-1) = (x-1)^2- 7(x-1)\\\p(x-1) = x^{2} -2x+1-7x+7\\\\\p(x-1) =x^{2} -9x+8[/tex]
Therefore, The value of p (x-1) is;
⇒ [tex]p(x - 1) = x^{2} -9x+8[/tex]

The diagonal of a rectangle is 13 units. One side of the rectangle is 12 units. Find the length of the shortest side of the rectangle.
Answer:
Diagonal of the rectangle = 13 units c =13
side of rectangle = 12 units a = 12
area of the rectangle = l× b
In rectangle all the corner angle is 90 degree. A diagonal of the rectangle forms two right angle.so we use Pythagoras theorem.
formula ; a²+b²=c² a = 12 , c = 13
12²+b² = 13²
144 + b² = 169
b² = 169 - 144
=25
b = 5 units
a = 12 units

Decrease R1400 in the Ratio 7:3
Answer:
Step-by-step explanation:
It's hard to tell what you mean. I'm going to assume you mean that you want what is left to be 3/7 less.

Today, the price of a new cell phone is $129.
In 2000, the price of a similar cell phone was $240.
What is the percent of change in the price of a cell phone from 2000 to today? Round to the nearest whole percent.
Answer:
54%
Step-by-step explanation:
129/240 = 0.5375 (divided to find the % change)
0.5375 * 100 (to convert decimal to percent form)

Pennsylvania has a sales tax of 6%. The city of Philadelphia adds an extra local sales tax of 2%. Both taxes apply to the original price of an item. If the shelf price of a bottle of sports drink is $2 in Philadelphia, PA, which expressions can be used to show the total taxes you would expect to pay?
Answer:
For the regular tax in Pennsylvania, it would be 12 cents or $0.12. For Philadelphia, it would be 4 cents or $0.04. I got these two amounts by multiplying 2 times 6 or 2 percent, aka 0.06 and 0.02. If you added the two together, you would get, $0.16 or 16 cents. You would then add that to the two dollars and end up with $2.16 or two dollars and sixteen cents. I hope this helps.

Find all the missing sides and angles (picture attached)
Answer:
[tex]\boxed{x=73.74}[/tex]
[tex]\boxed{y=16.26}[/tex]
[tex]\boxed{z=25}[/tex]
Step-by-step explanation:
Hello there!
Algebra 1
The first thing we should find is the missing angle
Because this is a right triangle we can solve it using the Pythagorean Theorem
The Pythagorean theorem states that the sum of the two legs squared equal the hypotenuse squared
the formula... [tex]a^2+b^2=c^2[/tex] where a and b = legs and c = hypotenuse
we are given two legs so we plug in a and b and solve for c
[tex]7^2+24^2=c^2\\7^2=49\\24^2=576\\576+49=625\\625=c^2\\\sqrt{c^2} =c\\\sqrt{625} =25\\c=25[/tex]
so we can conclude that the missing side length ( or z) equals 25
now to solve for the angles
Trigonometry
We can solve for y using sin
sin = opposite side divided by the hypotenuse
the opposite of y is 7 and the hypotenuse is 25
so we set up an equation [tex]sin(y)=\frac{7}{25}[/tex]
now we solve for y
[tex]\frac{7}{28} =.28\\arcsin(y)=y\\arcsin(.28)=16.26020471[/tex]
then we round to the nearest hundredth
so we can conclude that angle labeled y = 16.26
basic geometry
Remember all of the angles in a triangle add up to equal 180 so we can find x by subtract the known angles from 180
180 - 90 - 16.26 = 73.74 so we can conclude that x = 73.74
Jo said 565 times 34 one half is 595111 eight fourths is she correct. If not what is the correct answer.
Answer: Incorrect, 19492.5
Step-by-step explanation:
Given
Jo said 565 times 34 one half i.e. [tex]565\times 34\ \dfrac{1}{2}[/tex] is [tex]595111[/tex]
Solving for a mixed fraction
[tex]\Rightarrow 565\times \dfrac{34\times 2+1}{2}\\\\\Rightarrow 565\times \dfrac{69}{2}=\dfrac{38985}{2}=19492.5[/tex]
Clearly, [tex]19492.5\neq 595111[/tex]
Thus, Jo is wrong

The graphs below were created by an advertising agency for the computer store TechPlus to show its average price on laptops and desktops compared to another computer store's prices.
Which of the following statements best explains how the advertising agency misrepresented the data?
The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.
The graphs were created with different colors.
The graph for CompStar makes its prices appear much higher, but its prices are only a little higher.
The graphs do not include tablet computers, so there is not enough information to compare their prices.
The misrepresentation lies in the fact that ; The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.
Taking a look at both graphs, it could be observed on the y - axis that the graphs do not follow the same scale.
For CompStar, the y-axis which shows the price of laptops and desktops starts it's labeling from $0 ; while TechPlus's labeling began from $600
This representation means that comparing the two graphs would give an erroneous inference as it would make the price of TechPlus appear lower than that of Complus.

what is the measure of angle x?
Answer:
C
Step-by-step explanation:
first we want to find the missing angle at the top
to do that we subtract the given angles by 180
the square indicates that the angle is a right angle or that it equals 90
180-90-40=50
we know that the angle equal to 50 and x are supplementary angles so they will add up to equal 180 so to find x we subtract 50 from 180
180-50-130 so the answer is c

A. X > 14
C. x > 130
B. x < 14
D x <130
I
Answer: A. X > 14
Step-by-step explanation:
1. 10x > 140. We need to eliminate that 10 so it is just X. So, we divide both numbers.
2. 10 / 10 = 1, so it just becomes x
3. Now, we divide the other side.
140 / 10 = 14
