Answer:

Step-by-step explanation:

As you see in the equation, there is a simple rule to apply in any equation make you confuse with - or + symbol. When 2 minus symbol ( - ) stand together, it would become positive or plus symbol (+), so in this situation:

5 - [ - ( - 2)]

= 5 - (+ 2)

= 5 - 2

= 3

Hope this help you :3

Free_Kalibri [48]

Answer:

r = 8 units

Step-by-step explanation:

The circumference is calculated using $C = 2\pi r$ . Substitute C = 50.24 units. Solve for the radius.

$C = 2 \pi r\\50.24 = 2 \pi r\\25.12 = \pi r\\8 = r$

wolverine [178]

Answer:

the y intercept is 4

and frm that point to another spot on the line you go DOWN one unit (negative)

and two units to positive (to the right) thus the slope is - 1 (down) and 2 positive to the right

-1/2 = slope

y = -1/2 + 4

I need to know how to do the answer and why that’s the anwer

Pavel [41]

Ok so the answer is
$4 {x}^{2}$

so we multiply numbers that have the same variable

$2 {x}^{3} \: \: \times {2x}^{ - 1} \\ \\$
multiply 2 x 2

$2 \times 2 = 4$
then multiply the exponents

$x ^{3} \times x ^{ - 1}$
multipling like this will look like addition.
${x}^{3} \times {x}^{ - 1} = {x}^{2}$
so in other words you could do it like this too
${x}^{3} + {x}^{ - 1} = {x}^{2}$
now add the exponent with 4
$4 + {x}^{2} = 4x ^{2}$

now for the last part
${y}^{3} + {y}^{ - 3} = 0$
because -3 and 3 added together make 0
$0 + 4 {x}^{2} = 4 {x}^{2}$
I hope this help(it looks complicated but it's very easy and I hope I helped you out)
