Consider the linear function that is represented by the equation y = 2 x + 2 and the linear function that is represented by the
frutty [35]

Answer:

C) the function represented by the graph has a steeper slope and the function represented by the equation has a larger y-intercept.

Step-by-step explanation:

The equation is written in slope-intercept form, y=mx+b.  m is the slope and b is the y-intercept.  In this function, the slope is 2 and the y-intercept is 2.

Looking at the graph, the y-intercept is 1.  Going from the y-intercept, if we go up 2, it does not go over quite 1 unit.  Therefore the slope is steeper on the graph.

Hope I helped answer the question:)

Any help with this greatly appreciated.
Anestetic [448]

Put the equation in standard linear form.

x'(t) + \dfrac{x(t)}{t + 5} = 5e^{5t}

Find the integrating factor.

\mu = \exp\left(\displaystyle \int \frac{dt}{t+5}\right) = e^{\ln|t+5|} = t+5

Multiply both sides by \mu.

(t+5) x'(t) + x(t) = 5(t+5)e^{5t}

Now the left side the derivative of a product,

\bigg((t+5) x(t)\bigg)' = 5(t+5)e^{5t}

Integrate both sides.

(t+5) x(t) = \displaystyle 5 \int (t+5) e^{5t} \, dt

On the right side, integrate by parts.

(t+5) x(t) = \dfrac15 (5t+24) e^{5t} + C

Solve for x(t).

\boxed{x(t) = \dfrac{5t+24}{5t+25} e^{5t} + \dfrac C{t+5}}
