Step-by-step explanation:
The equation px²+px+3q=1+2x has roots 1/p and q
(a) Find the values of p and of q
Answer:
p = 2/3
q = 1/2
Step-by-step explanation:
The given equation is ,
[tex]\sf\to px^2 + px + 3q = 1 + 2x [/tex]
We can write it as ,
[tex]\sf\to px^2 + px + 3q - 1 -2x=0 [/tex]
Rearrange the terms ,
[tex]\sf\to px^2 - 2x + px + (3q -1)=0 [/tex]
This can be written as ,
[tex]\sf\to px^2 + x ( p - 2) + (3q -1) =0[/tex]
Now wrt Standard form of a quadratic equation ,
[tex]\bf \implies ax^2+bx + c = 0 [/tex]
we have ,
a = p b = p - 2 c = 3q - 1We know that product of zeroes :-
[tex]\to \sf q \times \dfrac{1}{p} = \dfrac{3q-1}{p } \\\\\sf\to 3q - 1 = q \\\\\sf\to 2q = 1 \\\\\sf\to \boxed{ q =\dfrac{1}{2}}[/tex]
Sum of roots :-
[tex]\to \sf q + \dfrac{1}{p} = \dfrac{2-p}{p} \\\\\sf\to \dfrac{ qp + 1}{p}= \dfrac{2-p}{p} \\\\\sf\to qp + 1 = 2 - p \\\\\sf\to p/2 + p = 1 \\\\\sf\to 3p/2 = 1 \\\\\sf\to \boxed{ p =\dfrac{2}{3}}[/tex]

How many cookies will Tanya have if she bakes 12 more batches y = 70 + 18 (x)
y=70+18(x)
y=70+18(12)
y=70+216
y=286
Step-by-step explanation:
since Tanya bakes 12 more cookies,
x=12
y= 70 + 18(12)
y=70 + 216
y= 286
therefore, she bakes 286 cookies with twelve more batches
y=-3x+5
5x-4y=-3
pls help
Hello!
[tex]\large\boxed{x = 1, y = 2}[/tex]
We can solve this system using substitution.
Since y = -3x + 5, we can substitute this into the following equation:
5x - 4(-3x + 5) = -3
Simplify:
5x - 4(-3x) - 4(5) = -3
5x + 12x - 20 = -3
Combine like terms:
17x - 20 = -3
Add 20 to both sides:
17x = 17
x = 1
Substitute to find y:
y = -3(1) + 5
y = -3 + 5
y = 2
Solution: (1, 2)
Answer:
(1,2) x=1; y=2
Step-by-step explanation:
We can plug the value of Y into the second equation like so:
[tex]5x-4(-3x+5)=-3\\5x+12x-20=-3\\17x=-3+20\\17x=17\\x=1[/tex]
Then we can plug the value of x into the first equation.
[tex]y=-3+5\\y=2[/tex]

A rectangular floor of area 360 m2 is going to be tiled. Each tile is rectangular, and has an area of 240 cm2. An exact number of tiles can be put into the space. How many tiles will be needed?? Solve fast
Answer:
1500
Step-by-step explanation:
The area of the regtangular floor is 360m². The floor is going to be retired with tiles having area of 240cm² . We need to find the number of times . Therefore ,
[tex]\implies 360m^2 = 360 \times 10^4 \ cm^2 [/tex]
And , the number of tiles required will be ,
[tex]\implies n =\dfrac{Area \ of \ floor}{Area \ of \ a \ tile }\\\\\implies n =\dfrac{ 360 \times 10^4 \ cm^2}{240 cm^2} \\\\\implies \underline{\underline{ n = 1,500 }}[/tex]
Hence the required answer is 1500 .

Answer: The slope is 2 -Please mark brainliest
1. Find the X and Y values of each point
X1: 1
X2: -1

X: -1-1=-2
3. Divide the X value by the Y value
-4/-2=2
The slope of the line shown on the coordinate plane is 2.
Answer:
2
Step-by-step explanation:
(X1,Y1)=(1,3)
(X2,y2)=(-1,-1)
slope(m)=y2-y1/x2-x1
= -1-3/-1-1
= -4/-2
= 2

[tex]3(x + 4) = 123 \\ 3x + 12 = 123 \\ 3x = 123 - 12 \\ 3x = 111 \\ x = \frac{111}{3} \\ x = 37[/tex]
=> The answer is 37.
Answer:
X=37
Step-by-step explanation:
3(x+4)=123
3x+12=123
3x=123-12
3x=111
3x/3 =111/3
x=37

Rectangle PQRS is rotated 90° clockwise about the origin.
On a coordinate plane, rectangle P Q R S has points (negative 3, negative 1), (negative 1, negative 1), (negative 1, negative 4), (negative 3, negative 4).
What are the coordinates of R’?
R’(4,–1)
R’(–4,1)
R’(1,4)
R’(–1,–4)
Answer:
R' (-4 , 1)
Step-by-step explanation:
Rotation of 90°
(Clockwise)
(x, y) ----> (y, -x) (take opposite of x, then switch the x and y)
Rotation of 90°
(CounterClockwise)
(x, y)------>(-y, x)
Rotation of 180°
(Both Clockwise and Counterclockwise)
(x, y) ----->(-x, -y)
Rotation of 270°
(Clockwise)
(x, y) ----->(-y, x)
Rotation of 270°
(CounterClockwise)
(x, y)------>(y, -x)
Answer:
The answer is: R'(-4,1).
Step-by-step explanation:
If the 90 degree angle is clockwise, the new figure will be in quadrant 2 (or in the section directly above the pre-image). Therefore, (x,y) maps to (y,-x), which will give us (-4,1).

A group of hospital workers belonging to a union each earn the same hourly wage. The union dues are 2 percent of each paycheck regardless of whether the employee works full-time, half-time, or quarter-time. Does this mean that the amount of money deducted will be the same for all the employees?
Answer:
No, different amounts will be deducted.
Step-by-step explanation:
Because the amount deducted is a percent, it changes based on the total amount.
For example, If someone takes 10% of $100, they will have taken $10. And if they take 10% from someone who has $10, they will have taken $1.

The following trapezoidal theorem states that:
Middle segment = average of top and bottom side
Thus:
M = 1/2(b1 + b2)
21 - x = 1/2(17 + 11)
Solve:
21 - x = 1/2(28)
21 - x = 14
Subtract 21 from both sides:
-x = 14 - 21
-x = -7
Multiply both sides by -1:
x = 7

y =
Answer:
x = -2
y = 8
Step-by-step explanation:
8x + 5y = 24
y = -4x
8x + 5 (-4x) = 24 (Substitute y value)
8x - 20x = 24 (Multiply)
-12x = 24 (Combine like terms and divide)
x = -2
y = -4 (-2) (Substitute x value. Multiply)

A student winds a strip of paper eight times around a cylindrical pencil of diameter 7mm use the value 22/7 as pie to find the length of the paper
Answer:
176mm
Step-by-step explanation:
Given
Diameter of the pencil = 7mm
First, we need to find the length of one roll of paper
Circumference of one roll = πd
Circumference of one roll = 22/7 *7
Circumference of one roll = 22mm
Since a student winds a strip of paper eight times around a cylindrical pencil, then the length of the paper = 8 * 22 = 176mm
