Q3. A + B = 0 and AB = - 36.
What is the value of A-B?
Step-by-step explanation:
A + B = 0
A = -B
(-B)B) = -36
-B^2 = -36
B^2 = 36
B = 6, -6
So, A = -6, 6
A - B = -12
or
A - B = 12
Answer:
A - B = ± 12
Step-by-step explanation:
Given
A + B = 0 → (1)
AB = - 36 → (2)
Subtract B from both sides of (1)
A = - B ← substitute into (2)
- B(B) = - 36 ( multiply both sides by 0 1 )
B² = 36 ( take square root of both sides )
B = ± 6
Substitute into (1)
If B = 6 then A =- 6 and A-B = - 6 - 6 = - 12
If B = - 6 then A = 6 and A - B = 6 - (- 6) = 6 + 6 = 12

solve for y 3/2y+12=7/5y-20
HELP ASAP
Answer: y = -320
Steps: ³⁄₂y + 12 = ⁷⁄₅y - 20
Subtract 12 from both sides: ³⁄₂y + 12 - 12 = ⁷⁄₅y - 20 - 12
Simplify: ³⁄₂y = ⁷⁄₅y -32
Subtract ⁷⁄₅y from both sides: ³⁄₂y - ⁷⁄₅y = ⁷⁄₅y -32 - ⁷⁄₅y
Simplify: ⅒y = -32
Multiply both sides by ten: 10 · ⅒y = 10 · -32
Simplify: y = -320

E. (Three dots in the shape of a pyramid) q
Answer:
it's c. r ^ q
Step-by-step explanation:
I just did it in Edgy 2020
Answer:
Step-by-step explanation:
These are what the symbols mean so you can better understand them
p: I like to go to the beach
q: I like to eat ice cream
r: I do not enjoy rainy days
^ = means OR so a that has or in it.
v = means AND so any sentance with and in it
~ = not so any phrase that condridicts what the origional P,Q, and/or R
∴ = Therefore so any phrase with therefore.
So; p ∧ q would be P... OR... Q acording to the key above would be
I ilke to go to the beach OR I like to eat icecream.
You can figure out the rest! Hope this helps you!

Delia organised the same event last year . this year conference had a 12% increase in attendance compared to last year. 1071 people attended this year . how many attended last year?
Answer:
1071/112=1%
1%= 9.5625
100%= 9.5625*100 = 956.25
Example:
112 People attendet this year. If the increase Was also 12%, a 112 people equals 112%. So,
112/112=1
1*100= 100
However, I am suprised that 956 and 0.25 People attendet the prevoius year. Are you Sure the Numbers are correct?

Determine the preferred width of each class if you use 8 classes, a high of 87, and a low of 2. (this is a statistics question)
A. 15
B. 13
C. 11
D. 10
Answer:
11 ; C
Step-by-step explanation:
To get the class width, we start by finding the range of the data set
That will be; the highest number - the smallest number
= 87-2 = 85
We proceed by dividing the number of classes we want by this number
That will be 85/8 = 10.625
We now proceed to approximate this value to the nearest whole number = 11
Hence , 11 is the class width to use

A toy rocket is launched vertically upward from a 12 foot platform with an
initial velocity of 128 feet per second. Its height h, at time t seconds after
launch is given by the equation h(t) = -16t^2 + 128t +12 . How long will it
take the rocket to reach the ground?
Answer:
4 mins
Step-by-step explanation:
The time taken by the rocket to reach the ground is 8 seconds
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The toy rocket is launched from a platform
The height of the platform = 12 feet
The initial velocity of the rocket = 128 feet / second
Let the height of the launch be = h
Let the time taken by the rocket be = t
The height after the launch after t seconds is given by the equation
h ( t ) = -16t² + 128t + 12
Now , for the rocket to reach the ground , the equation will be
h ( t ) = -16t² + 128t
Since , it is launched from the 12 foot platform , the equation will be
h ( t ) = -16t² + 128t
The height of the rocket on reaching the ground h ( t ) = 0
Substituting the value of h ( t ) in the equation , we get
h ( t ) = -16t² + 128t
0 = -16t² + 128t
16t² - 128t = 0
16t ( t - 8 ) = 0
t - 8 = 0
Adding 8 on both sides , we get
t = 8 seconds
Hence , the time taken by the rocket to reach the ground is 8 seconds

In the diagram below, l || m and QR perpendicular ST at R.
If m<1 = 63. find m<2
Answer:
m<2 = 27°
Step-by-step explanation:
m<1 = 63° (given)
m<QTR = m<1 (alternate interior angles are congruent)
m<QTR = 63° (Substitution)
m<QRT = 90° (right angle)
m<2 + m<QRT + m<QTR = 180°
m<2 + 90° + 63° = 180° (substitution)
m<2 + 153° = 180°
Subtract 153° from each side
m<2 = 180° - 153°
m<2 = 27°
