Factor the following quadratic expression n^2+ 4n-12
Answer:
(n + 6)(n - 2)
Step-by-step explanation:
Given
n² + 4n - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the n- term (+ 4)
The factors are + 6 and - 2 , since
6 × - 2 = - 12 and 6 - 2 = + 4
Then
n² + 4n - 12 = (n + 6)(n - 2) ← in factored form
b is directly proportional to a.
b is 10 when a is 8.
Work out b when a is 9.
Answer:
B=11
Step-by-step explanation:
b=10 a=8
b=? a=9
Either you can cross multiple 10x9=90/8 (11.25, round down to 11), or you can look that 9 is 8+1, so of we do the same process to b then we would find our awnser. 10+1=11.
When a is 9 then, the value of b will be;
⇒ b = 45/4
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
'b' is directly proportional to a.
And, b is 10 when a is 8.
Now,
Since, 'b' is directly proportional to a.
Hence, We get;
⇒ b = ka
Where, k is constant of proportionality.
Here, b is 10 when a is 8.
So, Put b = 10 and a = 8;
⇒ b = ak
⇒ 10 = k × 8
⇒ k = 10 / 8
⇒ k = 5/4
So, When a is 9 and k is 5/4, then;
⇒ b = ak
⇒ b = 9 × 5/4
⇒ b = 45/4
Thus, The value of b = 45/4

Step-by-step explanation:
A model rocket is launched vertically from a platform 64 feet above the ground. The height of the rocket reaches during the flight is modeled by the equation h(t) = -16t² + 128x, where h is the height of the rocket and t is the time in seconds since the launch. Determine algebraically the time when the ball hits the ground.

Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))
Answer:
x=10.247
y=52.02
z=37.98
Step-by-step explanation:
For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.
For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle
For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle

X+2x=-4,3x-5y=-1 using elimination method
Answer:
x=-4/3, y=3/-5
Step-by-step explanation:
X+2X=-4
Then, adding up we get: 3x=-4
Then, x=-4/3
Substituting those we get: 3*(-4/3)-5y=-1
-4-5y=-1
-5y=-1+4=3
y=3/-5
Thus, x=-4/3, y=3/-5

Answer:
y = 20 + 35x or y = 35x + 20
Step-by-step explanation:
Looking at the problem, a cell phone company charges $20 for a new account, and $35/month for phone service. With that information we can quickly form this equation:
y = 20 + 35x
The y is the total cost, 20 is the initial charge, and 35x is the per-month charge.
What is below is the graph for this equation.

Step-by-step explanation:
you have first and second equation, YOU MUST FIND THE THIRD EQUATION
SOLUTION
FIND equation 3 from 2
x+2y=10
x=10-2y...........3
Substitute equation 3 from first (not from the equation where you got equation 3)
2 (10-2y)-7y=9
20-4y-7y=9
-11y=9-20
-11y= -11
-11y/-11= -11/-11
y=1
Find the value of x from the third equation
