Answer:
m = 68
Step-by-step explanation:
MN bisects it or splits it in half so we know N = M, which we could also write as 8x-12 = 5x+18 because they give us those equations
once you have 8x-12 = 5x+18 you can subtract 5x from both sides, so you will get 3x-12 = 18, then you can add 12 to both sides and you will get 3x = 30. Once you have narrowed down to this you can divide three by both sides making x = 10
Now that we know x =10 we can insert it into the equation
5(10) + 18 = m
50 + 18 = m
m = 68

f(x) = 3x + 10, g(x) = x - 2, Find g(f(x))
Answers
Answer with step-by-step explanation:
If g(x) = x - 2, then g(f(x)) = f(x) - 2. So the whole equation would be: 3x + 10 × x - 2. Simplified: g(f(x)) = 13x - 2
Hope this helped!
The composite function g(f(x)) = 3x + 8 if the f(x) = 3x + 10, g(x) = x - 2 after applying the concept of the composite function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
f(x) = 3x + 10
g(x) = x - 2
It is required to find the g(f(x))
g(f(x)) representing the composite function:
Plug f(x) = 3x + 10
In the function g(x):
g(f(x)) = (3x + 10) - 2
g(f(x)) = 3x + 8
Thus, the composite function g(f(x)) = 3x + 8 if the f(x) = 3x + 10, g(x) = x - 2 after applying the concept of the composite function.

Substitute the values of x and y into the expression -3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2. Match that value to one of the numbers. What matches what I'm stuck 1. x = 0.5, y = -1/10 2. x = -1, y = -3 3. x =3/4 , y = 2/5 4. x = 0, y = 2.5 5. x = √2, y = √2 6. x = 2, y = -1 The answer thing. -1 9.17 14 -11.25 1.665 0.44
Answers
Answer:
1. Putting x = 0.5, y = -1/10 gives 0.44
2. Putting x = -1, y = -3 gives 14
3. Putting x =3/4 , y = 2/5 gives 1.665
4. Putting x = 0, y = 2.5 gives - 11.25
5. Putting x = √2, y = √2 gives 17
6. Putting x = 2, y = -1 gives - 1
Step-by-step explanation:
-3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2
1. Putting x = 0.5, y = -1/10
-3(0.5)^2 + 2(-1/10)^2 + 5(-0.05) - 2(-1/10) + 5(0.5)^2 - 3(-1/10)^2
= -0.75 +0.02 - 0.25 +0.2 + 1.25- 0.03
= 0.44
2. Putting x = -1, y = -3
-3(-1)^2 + 2(-3)^2 + 5(3) - 2(-3) + 5(-1)^2 - 3(-3)^2
= -3 +18 +15+6+5-27
= 14
3. Putting x =3/4 , y = 2/5
-3(3/4)^2 + 2(2/5)^2 + 5(6/20) - 2(2/5) + 5(3/4)^2 - 3(2/5)^2
=- 27/16 +8/25 +30/20 -4/5 +45/16 - 12/25
= 18/16 - 24/25 + 30/20
= 18/16 - 96+150/100
= 18/16 +54/100
= 1800+ 864/1600
= 2664/1600
=1.665
4. Putting x = 0, y = 2.5
-3(0)^2 + 2(2.5)^2 + 5(0) - 2(2.5) + 5(0)^2 - 3(2.5)^2
= 12.5 - 5.0 - 18.75
= -11.25
5. Putting x = √2, y = √2
-3(√2)^2 + 2(√2)^2 + 5(√2.√2) - 2(√2) + 5(√2)^2 - 3(√2)^2
= -6 +4+10-4+19-6
= 17
6. Putting x = 2, y = -1
-3(2)^2 + 2(-1)^2 + 5(-2) - 2(-1) + 5(2)^2 - 3(-1)^2
= -12+2 -10 +2 +20 -3
= -1

If a toy rocket is launched vertically upward from ground level with an initial velocity of 135 feet per second, then its height h after t seconds is given by the equation h(t) = -16t2 + 135t. How long will it take the rocket to return to the ground?
Answers
Answer:
The toy rocket will return to the ground at 8.44 seconds
Step-by-step explanation:
The height h of the toy rocket launched vertically as a function of the time t is given by:
[tex]h(t)=-16t^2+135t[/tex]
The rocket will return to the ground when h=0:
[tex]-16t^2+135t=0[/tex]
Factoring:
[tex]t(-16t+135)=0[/tex]
There are two solutions:
t=0, t = 135/16 = 8.4375
The first solution corresponds to the moment the toy rocket was launched, the second is the time taken by the rocket to return to the ground.
The toy rocket will return to the ground at 8.44 seconds

1.) A deep-sea diver descends below the surface of the water at a rate of 5.5 feet each minute. What is the
depth of the diver after 1.3 minutes?
Write an expression to represent the problem:
Solve your expression in the box below and write your answer on the blank provided.
Answer
Answers
Answer:
The required expression for the depth is [tex]5.5t[/tex] feet.
The depth after 1.3 minutes is 71.5 feet.
Step-by-step explanation:
Let d be the depth of the sea below the surface of the water.
The rate of descending or the rate of increasing the depth, [tex]r= 5.5[/tex] feet/min.
Since, the rate is constant, so,
If the diver reaches the depth, [tex]d[/tex], in time, [tex]t[/tex]. So,
[tex]r= d/t[/tex]
[tex]\Rightarrow d=r\times t[/tex]
So, for [tex]r=5.5[/tex] feet/min, the required expression for the depth is [tex]5.5t[/tex] feet.
After time t= 1.3 minutes.
The depth, [tex]d = 5.5 \times 1.3 = 71.5[/tex] feet.
