Answer:
p=-9
Step-by-step explanation:
11= p-7-3p
you can slove p-3p now which is -2p, then add -7 to both sides.
18=-2p
then divide by -2
p=-9

point G is rotated 90°. the coordinate of the pre-image G was (7,-5), and it’s image G’ is at the coordinate (5,7). What is the direction of the rotation
Answer:
The Direction of the rotation is counterclockwise around the origin.
What was Given was that Point G is rotated 90°. The coordinate of the pre-image point G was (7, –5), and its image G’ is at the coordinate (5, 7).
What you need to find was : What is the direction of the rotation.
So coming to conclusions is we have given that Point G is rotated 90°.
The Pre-image of G = ( 7, -5).
Translated image G' = ( 5 ,7).
By the Rotation rule of 90° is : (-y, x) 90 degree rotation counterclockwise around the origin.
(y, -x) 90 degree rotation clockwise about the origin.
We can from G (7,-5) and G'( 5 ,7) it is rotation counterclockwise around the origin.
Therefore, Direction of rotation is counterclockwise around the origin.

The distance that a object covered in time was measured and recorded in the table. What equation would describe this motion?
A) y = 2x + 1
B) y = 3x + 1
C) y = 2x
D) y = 3x
Thank you.
Answer:
D y=2x
Step-by-step explanation:
Using slope formula change in y over change in x
[tex] \frac{2}{1} [/tex]
the slope is 2 and when we plug the x value in it gives us our corresponding y value so the answer is D
Suppose a city with population 300000 has been growing at a rate of 3% per year. If this rate continues, find the population of this city in 17years.
The Beechcraft 1900D is a commuter airplane with a fuel capacity of 665 gallons. The function that represents how the amount of fuel changes as a function of distance flown is f(x)=−0.9x+665, where x represents miles flown, and f(x) represents the amount of fuel remaining. What is the rate of change for this scenario?
Given:
The function that represents how the amount of fuel changes as a function of distance flown is
[tex]f(x)=-0.9x+665[/tex]
where x represents miles flown, and f(x) represents the amount of fuel remaining.
To find:
The rate of change for this scenario.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope or rate of change and b is the y-intercept.
We have,
[tex]f(x)=-0.9x+665[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=-0.9[/tex]
Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.

EXPLAIN why the solution to the absolute value inequality | 4x - 9 | ≥- 12 is all real numbers.
Answer:
no matter what value you substitute for x, the absolute value will force the result to be a positive number and any positive number is greater than -12
Answer: Since the absolute value of any number is always greater than or equal to zero, then the given inequality holds for every real number.
Explanation: It doesn't matter which number you substitute for x, as the absolute value will convert the number into a positive one, which will always be greater or equal to 0. Hence, every real number can be a possible answer.
A chocolate pastry cost Rs.26 and a fruit pastry cost Rs.18 Jenny buys both
these pastries together for Rs. 500 how many of each did she buy ?
Let's assume the no. of chocolate pastry bought = x
and the no: of fruit pastry bought = y
➣ Cost of 1 chocolate pastry = Rs 26
➣ Cost of x chocolate pastry = Rs 26x
➣ Similarly, cost of fruit pastry = Rs 18 y
➣ It is given that the total cost = Rs 500
Therefore, Rs 26x + Rs 18 y = Rs 500
If we assume x = 4 and y = 22 , then
26 x 4 + 18 X 22 = Rs 500
104 + 396 = 500
⇝ No. of chocolate pastries bought = 4 ✔
⇝ No. of fruit pastries bought = 22 ✔

Step-by-step explanation:
Answer:
10% of the pupils have not finished their assignment.
Step-by-step explanation:
3/30 kids have not finished their assignment.
3/30 = 1/10 = 10/100 = 10%
Hope this helps!
From V
what is the percent decrease of 2,400 to 2,100?
#You times it with ×100 to get the percentage
#Part of the number/total number
2400 - 2100 = 300
300/2400 × 100 = 12.5%
So the percentage decreased is 12.5%
Find the mZNPI
Exterior angles of triangle
Given:
The figure of a triangle.
To find:
The exterior angle of the triangle m∠NPI.
Solution:
According to the exterior angle theorem, value of exterior angle of a triangle is equal to the sum of the opposite interior angles.
Using the exterior angle theorem, we get
[tex]m\angle NPI=65^\circ+78^\circ[/tex]
[tex]m\angle NPI=143^\circ[/tex]
Therefore, the measure of angle NPI is 143 degrees.

A 13 feet ladder is placed 5 feet away from a wall. The distance from the ground straight up to the top of the wall is 13 feet Will the ladder the top of the wall?
Answer:
the answer is
a^2 + b^2 = c^2
5^2 + b^2 = 13^1
25 + b^2 = 169
b^2 = 144
b = 12
or
The ladder is the hypotenuse, and the two legs are distance from the wall and height of the wall. If it is moved 5 feet away, it will reach 12 feet high, for 5^2+12^2=13^2.

Make a conjecture of what the x-intercepts of the function
f(x) = (2x - 1)(x + 3) will be.
Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2
Find the measure of 14x+7+44+9x+3=180?
61° is the measure of <STW
How to find the measure of <STW?To solve this problem, we need some angle geometry knowledge
Given: <SRT = 44°, <RST = 9x+3, <RTW = 14x+7
<RTW = <SRT + <RST (exterior angle of a triangle is equal to the sum of opposite interior angles)
14x+7 = 44 + 9x+3
14x -9x = 44+3-7
5x = 40
x = 40/5 = 8
<STW + <RTW = 180 (sum of angles on a straight line)
<STW = 180 - <RTW
<STW = 180 - (14x+7)
Substitute x = 8:
<STW = 180 - (14(8) +7)
<STW = 180- 119 = 61°
Therefore, the measure of <STW is 61°
