Answer:

the solution is (1, 5)

Step-by-step explanation:

If d - e = 4, then d = e + 4. Substitute e + 4 for d in the first equation:

d + e = 6 → e + 4 + e = 6. Then 2e = 2, and e = 1.

Subbing 1 for e in the second equation, we get d + e = 6, or d + 1 = 6.

Thus, d = 5, and the solution is (1, 5)

A circle has a diameter with endpoints at 3 – 5i and –8 + 2i. What is the center of the circle?

bagirrra123 [75]

So we got the real axis and the imaginary axis
we just need to find the average of the 2 points

remember
midpoint of (x1,y1) and (x2,y2) is

((x1+x2)/2,(y1+y2)/2)
so

average of 3 and -8 is -5/2
average of -5i and 2i is -3/2i

center is -5/2-3/2i

0.15(y-0.2)=2-0.5(1-y)<br><br> The answer is -153/35 I just need to know how to get that

butalik [34]

Answer:

$y=-\dfrac{153}{35}$ .

Step-by-step explanation:

The given equation is

$0.15(y-0.2)=2-0.5(1-y)$

Using distributive property, we get

$0.15(y)+0.15(-0.2)=2-0.5(1)-0.5(-y)$

$0.15y-0.03=2-0.5+0.5y$

$0.15y-0.03=1.5+0.5y$

Isolate variable terms.

$0.15y-0.5y=1.5+0.03$

$-0.35y=1.53$

Divide both sides by -0.35.

$y=\dfrac{1.53}{-0.35}$

$y=-\dfrac{1.53}{0.35}\times \dfrac{100}{100}$

$y=-\dfrac{153}{35}$

Therefore, $y=-\dfrac{153}{35}$ .

Y=2cos3x<br> How do I graph this with labels in radians

aleksandrvk [35]

Answer:

Linked an image

Step-by-step explanation:

Okay, basically since it is y=2co3x you know that the amplitude is 2, so rather than going to +1 and -1, you now go to +2 and -2. Since it's cosine, you also know that you start at the maximum rather than the intercept, so the starting point is at (0,2).

I'm assuming that you need to graph 2 periods, and to find the periods you divide 2pi/b, so, in this case, 2pi/3

Then lastly you need to find the four points between 0 and 2pi/3, so you divide 2pi/3/4 to get 2pi/12=pi/6

If you have any other questions just comment and I'll respond when I see it.

If the consumption function is C = $200 billion + 0.5Y, Note: some values are in 'trillions' and others are in 'billions'. (

Strike441 [17]

Answer: The marginal propensity to consume (MPC) in the given equation is 0.5.

The formula above is in slope intercept form. The MPC is like the slope of the equation. It gives the change in consumption, C, over the change in income, Y.

For example, if we let Y = 1, then the consumption will go from 200 to 200.5. It was a change of 0.5 over 1. Or just 0.5.
