First take out the parenthese

then you can subtract 2i from -1i to get i

then add 4 to 3

hence the answer, 7/i

Evaluate the expression for x = 2 and y = 4. Enter your answer in the box.<br><br> 16x0 + 2x2 • y –1

swat32

Given that,

The given expression is : $16x^0+2x^2{\cdot}y^{-1}$

To find,

The value of the above expression when x = 2 and y = 4

Solution,

We have,

$16x^0+2x^2{\cdot}y^{-1}$

Put x = 2 and y = 4 in the above expression.

$16x^0+2x^2{\cdot}y^{-1}\\\\=16\times (2)^0+2(2)^2\times (4)^{-1}\\\\=16\times 1+2(2)^2\times\dfrac{1}{4}\\\\=16+2\\\\=18$

So, the value of the above expression is 18.

Which equation represents the line that passes through the points (3-,7) and (3,3)?

aivan3 [116]

Answer:

Did you mean (-3, 7) for the first point?? If so, the answer is

D) y = -2/3x + 5

Step-by-step explanation:

Find the slope: (m)

3-7 / 3+3 = -4/6=-2/3=m

Find the y intercept (b): (plug in y, x, and m)

3=-2/3(3) +b

3=-2+b

5=b

Write equation using y=mx+b

y = -2/3x+5

Over 30 points please help me i need it bad

pashok25 [27]

Distance formula: d= square root of (x2-x1)^2+(y2-y1)^2
(3,5) (7,3)
d= square root of (7-3)^2+(3-5)^2
d= square root of (4^2)+(-2^2)
d= square root of 16+4
d= square root of 20
d=4.47...rounded= 4.5
Hope this helped!
