How do you perform the indicated operations and write the answer in form a+bi where a and b are real numbers?

It's difficult to answer this question without seeing the "indicated operations" the form a+bi is a standard form for imaginary numbers so you might see 2+3i, you can add this to say 4+5i by adding the real numbers (2+4) and the imaginary numbers (3+5) to get 6+8i. Hope that helps.

identify and equation in point-slope form for the line perpendicular to y=-1/2x-7 that passes through (-3,-2)

bazaltina [42]

Answer:

y +2 = 2(x +3)

Step-by-step explanation:

The equation in point-slope form for a line with slope m through point (h, k) is ...

y -k = m(x -h)

The slope of your given line is the coefficient of x, -1/2. The slope of a perpendicular line will be the negative reciprocal of that: -1/(-1/2) = 2. So, you have m = 2, (h, k) = (-3, -2), and your desired equation is ...

y -(-2) = 2(x -(-3)) . . . . . . which can be simplified to ...

y +2 = 2(x +3)

Rudik [331]

Integers are any whole number(not fraction) that can be possitive or negative however she can not buy a negative amount of tickets so that is not the answer
whole numbers are any not fraction number that is positive this is a possible answer
rational numbers are any number that is terminates if it is a decimal or is a repeating decimal this does not include decimals like pi that don't end and dont repeat this cant be the answer
a real number is any number rational or irrational this also cant be the answer

the answer is B
i hope i made sense

Uzanne can work 10 math problems in 15 minutes. How many can she work in an hour and a half?

jeyben [28]

1 and half hour
= 60 minutes+ 30 minutes
= 90 minutes

Now,

Uzanne need 15 minutes to do 10 problems
Uzanne need 1 minute to complete 10/15 problems

Uzanne need 90 minutes to do
= (10/15)*90
=(2/3)*90
=2*30
=60 problems
