Y=2x y=-1/2x+5 system of equations
dalvyx [7]

Answer:

<em><u>x=2, y=4</u></em> (as a point,) (2, 4)         (last part is unnecessary unless you are graphing)

Step-by-step explanation:

Use substitution.

Substitute y for 2x.

Since y=2x, you can plug 2x into the place where y goes...

Instead of y=-1/2x+5

2x=-1/2x+5....Now solve

2.5x=5 (Sorry my computer cannot type fractions very clearly)

/2.5    /2.5        (dividing by 2.5 on both sides)

<u><em>x=2</em></u>

Now just plug x into any of the equations to find y (preferably the easier one).

y=2x becomes

y=2*(2)

=4

<em><u>y=4</u></em>

Whats 2x2+34x24+3x0+1x400x100x456x0
aivan3 [116]

Answer:

820

Step-by-step explanation:

If you use order of operations, you can find that 3x0 and 1x400x100x456x0 is just 0 so you just have to add 2x2 and 34x24. Which is 820

order of operations is

GEMDAS

Grouping symbols

exponents

multiplication and division (these don't have to be in order)

Addition and Subtraction (again, these don't have to be in order)

The length of human pregnancies from conception to birth varies according to an approximately normal distribution with a mean of
Varvara68 [4.7K]

Answer:

A) 68.33%

B) (234, 298)

Step-by-step explanation:

We have that the mean is 266 days (m) and the standard deviation is 16 days (sd), so we are asked:

A. P (250 x < 282)

P ((x1 - m) / sd < x < (x2 - m) / sd)

P ((250 - 266) / 16 < x < (282 - 266) / 16)

P (- 1 < z < 1)

P (z < 1) - P (-1 < z)

If we look in the normal distribution table we have to:

P (-1 < z) = 0.1587

P (z < 1) = 0.8413

replacing

0.8413 - 0.1587 = 0.6833

The percentage of pregnancies last between 250 and 282 days is 68.33%

B. We apply the experimental formula of 68-95-99.7

For middle 95% it is:

(m - 2 * sd, m + 2 * sd)

Thus,

m - 2 * sd <x <m + 2 * sd

we replace

266 - 2 * 16 <x <266 + 2 * 16

234 <x <298

That is, the interval would be (234, 298)

What is x when -2/3(x+3/5)=3/5
Vikentia [17]
The answer x=-3/2
Multiply both sides by 3 then multiply both sides by 5 last divide both side by those and you will get -6 so you would divide those and get your answer
