Answer:

The system of equations has no solution

Step-by-step explanation:

The method of substitution consists in solving one equation for a variable and replacing it in the other equation.

In this case one of the equations is already solved for one of the variables ( $y$ ):

$y = -2x + 1$

So the next step is to plug this in the other equation wich is:

$4x + 2y = -3$

So we will have

$4x + 2(-2x + 1) = -3$

solving the parenthesis:

$4x-4x -2= -3$

$-2= -3$

wich is not a valid answer, so the system of equations has no solution.

4x+2(-2x+1)=-3
4x-4x+2=-3
2=-3 is not a true statement.

The answer is no solution

Let the function f be continuous and differentiable for all x. Suppose you are given that f(−1)=−3, and that f'(x) for all value

Monica [59]

Answer:

Step-by-step explanation:

By MVT,

$f'(c) = \frac{f(5)-f(-1)}{5-1}$

$4f'(c)= f(5) + 3\rightarrow f(5) = 4f'(c) - 3$

Moreover, $f'(x)\leq 4~~~~~~ \forall x,$

$f(5) \leq 16 - 3 =13$

Hence the largest possible value of f(5) is 13

Find the length of the third side to the nearest tenth 6 and 9

oee [108]

Hello, i do believe that you are asking me to do pythagorean theorem.

I'm not too sure if we are solving hypotenuse or a/b so i'll do both.

$\boxed{\underline{Hypotenuse...}}\\\\\\A^2+B^2=C^2\\6^2+9^2=C^2\;\\36+81=117$

$\sqrt{117}=10.816\\Round-\;10.8$

$\boxed{\underline{a/b...}}\\\\\\A^2=C^2-B^2\\A^2=9^2-6^2\\A^2=81-36\\A^2=45\\\sqrt{45}= 6.708\\Round-\;6.7$

Hope it helps!

Which of the following is the result of expanding 4 £ n=1 (2n-3)

geniusboy [140]

Answer: 8

Step-by-step explanation: the given expression is 2n-3

so when n=1, we will get, 2(1)-3=2-3=-1

when n=2, we will get, 2(2)-3= 4-3=-1

when n=3, we will get 2(3)-3= 6-3=3

when n=4, we will get 2(4)-3 = 8-3=5

so the required result of expansion is -1+1+3+5=8

answer is 8.

hope that helped!

What transformation takes the graph of f(x)=2x+3 to the graph of g(x)=2x+4 ?

Zolol [24]

The original function f(x) = 2x+3.

And the transformed function is g(x) = 2x+4.

We can see that if we add 1 into function f(x), we get

f(x) +1 or 2x+3+1 = 2x+4.

<h2>So, 1 is being added in original function f(x) and we get g function g(x) = 2x+4.</h2>

<em>According to rules of transformations, when we add some number k in the given function, it move k units up and if we subtract k from given function, it move k units down.</em>

<h3>Therefore, correct option is B option.</h3><h3>B. translation 1 unit up.</h3>

Week 3: Linear Functions

spayn [35]

Answer:

D. y = 1.5x +5

Step-by-step explanation:

The offered answer choices are equations in slope-intercept form. The constant in the equation is the y-intercept, the value of distance when time is zero.

y = mx +b . . . . m is slope; b is y-intercept

The table tells you that the distance value is 5 when the time value is 0. In the equation, that means ...

b = 5

Only one answer choice matches:

y = 1.5x +5
