Blababa [14]

Answer:

Step-by-step explanation:

$y = x^2+ 10x - 2\\\\y = x^2+ 2\cdot x\cdot5+5^2-5^2 - 2\\\\y=(x+5)^2-25-2\\\\y=(x+5)^2-27$

17+(-4)-4/5j-2/5j+6

Snowcat [4.5K]

Answer:

19 - (6/5)j

Step-by-step explanation:

In this expression we have addition, subtraction and multiplication.

According to order of operations rules, mult. and div. must be carried out before add. or subt.

Therefore, we begin with 17+(-4), which becomes 17 - 4, or 13.

Next we see -4/5j, by which I assume you mean -4/5 * j.

Summarizing what we have so far:

13 - (4/5)j - 2/5j + 6

Combining the j terms, we get

13 - (6/5)j + 6, which collapses to 19 - (6/5)j.

Find the slope of the line 7x-4y=10

Harman [31]

Answer:

The slope is $m=(7/4)$

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

$7x-4y=10$

Convert to slope intercept form

Isolate the variable y

$4y=7x-10$

$y=(7/4)x-(10/4)$

$y=(7/4)x-(5/2)$

The slope is $m=(7/4)$
