What value of a in the equation ax − 4 = 2y would give a line with a slope of 2?
sukhopar [10]

Answer:

a=4

Step-by-step explanation:

ax − 4 = 2y

We need to get the equation is slope intercept form  y= mx+b.

Lets solve for y

Divide each side by 2

a/2 x - 4/2 = 2y/2

a/2 x -2 = y

or y=a/2 x -2

The slope is a/2 and the y intercept is -2

We want a slope of 2  so a/2 =2

a/2=2

Multiply each side by 2

a/2 * 2 =2*2

a =4

HELP ME PLEASE!!
Zolol [24]

Answer:

domain: (-infin., infin.)

range: (-infin., infin.)

Step-by-step explanation:

This is an odd degree polynomial which forms a sideways S shape starting low and ending high. Since nothing restricts the function from having an output for every real number input, the domain and range are (-infin., infin.).

Twice as many men as women attended the concert. If the total attendance was 714, how many women
mixas84 [53]

Answer:

Step-by-step explanation:

This is actually pretty simple. If x= a person, then 2x is men, and x is women.

You just have to solve for x.

714=2x+x

714=3x

x=238

Then you have to multiply it back out.

Men: 476

Women: 238

I hope this helps!

If you need help with anything else, or this answer just doesn't make sense, just let me know!

The answer would be 23i.

Simplify ( 26 + 16i - 26 + 7i )

Gather like terms ( 26 - 26 ) + (16i + 7i)

Simplify (23i)
