Answer:

7

Step-by-step explanation:

to find the value of of x. you have to substitute 4 into y and solve the equation for x. 8x minus 2 times 4 = 48. 2 times 4 is 8. your left with 8x-8=48. next you add 8 to both sides and are left with 8x=56. next 8x divided by 8 is x. and 56 divided by 8 is 7. So x=7.

Rufina [12.5K]

Answer:

B

Step-by-step explanation:

We are given that <em>x</em> and <em>y</em> are functions of time <em>t</em> such that <em>x</em> and <em>y</em> is a constant. So, we can write the following equation:

x(t)+y(t)=k,\text{ where $k$ is some constant}

The rate of change of <em>x</em> and the rate of change of <em>y</em> with respect to time <em>t</em> is simply dx/dt and dy/dt, respectively. So, we will differentiate both sides with respect to <em>t: </em>

<em />\displaystyle \frac{d}{dt}\Big[x(t)+y(t)\Big]=\frac{d}{dt}[k]<em />

Remember that the derivative of a constant is always 0. Therefore:

\displaystyle \frac{dx}{dt}+\frac{dy}{dt}=0

And by subtracting dy/dt from both sides, we acquire:

\displaystyle \frac{dx}{dt}=-\frac{dy}{dt}

Hence, our answer is B.

Rewrite the equation by completing the square.<br> 4x^2 + 28x + 49=0
Evgen [1.6K]

Answer:

4(x+3.5)^{2}=0

Step-by-step explanation:

we have

4x^{2}+28x+49=0

step 1

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(4x^{2}+28x)=-49

step 2

Factor the leading coefficient

4(x^{2}+7x)=-49

step 3

Complete the square. Remember to balance the equation by adding the same constants to each side

4(x^{2}+7x+3.5^2)=-49+(3.5^2)(4)

4(x^{2}+7x+12.25)=0

step 4

Rewrite as perfect squares

4(x+3.5)^{2}=0
