7 0

Answer:

1. slope  is -1 and y intercept is 2

3. slope is -2 and y intercept is -4

2. slope is -4 and y intercept is 2

4. this is not a line - it is a parabola

Step-by-step explanation:

1. -4y = 4x -8

y = -x + 2

3. 4y = -8x -16

y = -2x - 4

2. y = -4x + 2

4. y - 14 = -3x^2 -16x

y = 3x^2 - 16x + 4

What is the answer...?
Finger [1]

Answer:The answer is c

Step-by-step explanation:

Multiply both side is the equation by -1.

Sum the equations vertically to eliminate at least one variable

Divide both sides of the equation by 3

Substitute the given value of y into the equation 2x+3y=8

and then solve for x

The function of x is \bold{\frac{-1x}{2}}.

<u>SOLUTION:</u>  

Given that, we have to write a linear function f with function of (-4) =2 and function of 6=(−3).

Now, let the linear function be \text{function of x}=a x+b

Then, function of -4 = a(-4)+b \rightarrow 2=-4 a+b \rightarrow b=2+4a \rightarrow (1)

And, function of 6 = a(6)+b \rightarrow-3=6 a+b \rightarrow b=-3-6a \rightarrow (2)

On equating (1) and (2) to find the value of a,

2+4a=-3-6a

On grouping the common terms,

4a+6a=-3-2 \rightarrow 10a=-5 \rightarrow a=\frac{-5}{10}

\Rightarrow a=\frac{-1}{2} \rightarrow (3)

On substituting the value of (3) in (1) we get,

b=2+4a \rightarrow b=2+4\times\frac{-1}{2} \rightarrow b=2+\frac{-4}{2} \rightarrow b=2+(-2)

\Rightarrow b=0

So, the function of x = \frac{-1x}{2}+0

The height, h, in metres, of a rocket t seconds after it is launched is approximately modelled by the quadratic relation h = 80t
8_murik_8 [283]

Answer: 5 s

Step-by-step explanation:

Given

Height of the rocket can be modelled as h=80-16t^2

Rocket will land on earth when it's height becomes 0

\Rightarrow 80t-16t^2=0\\\Rightarrow t(80-16t)=0\\\\\Rightarrow t=0\ \text{or}\ t=\dfrac{80}{16}=5\ s

Neglecting 0 value

Thus, rocket remains in air for 5 s.
