5x=2x+24 Subtract 2x from 5x so that the variable x is only on one side. 3x=24 Divide 3 on both sides so that the only thing remaining on the left side is the variable x. Final Answer: x= 8

5x=2x+24
5x-2x=24
3x=24
x=24/3
x=8

Now you can verify by putting 8 in the x :)

Simplify the expression square root of -25/(5-2i) + (1-3i)

Georgia [21]

Answer:

I guess $\frac{25}{6} -5i$

Step-by-step explanation:

$\frac{-25}{(5-2i)+(1-3i)}$ 1. rewrite the expression(it helps me tbh)

$\frac{-25}{5 - 2i+1-3i}$ 2. Distribute the positive symbol to (1-3i)

$\frac{25}{6-5i}$ 3. treat i as a variable while you combine like terms

$\frac{25}{6} -5i$ 4. divide 25 by 6-5i but leave 25/6 as a fraction since it can't be divisible.

Line m passes through the points (-4, 3) and (-4, 7). What is the slope of the line that is parallel to line m?

Oksi-84 [34.3K]

Gradient=rise/run=y2-y1/x2-x1

= 7-3(4)/-4--4(0)

As you can't divide by zero the line's equation is x=-4 so it doesn't have a gradient as such. However, a parallel line would be the y-axis

HELP ME OUT PLEASE I RLLY NEED IT ASAP. ):

LenaWriter [7]

(a) Slope is rise over run, or change in y over change in x.

1 -> 3 ( $\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{4 - -8}{-1 - -5} = \frac{4 + 8}{-1 +5}= \frac{12}{4} =\frac{12}{4}$ )

2 -> 3 ( $\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{1 - 7}{0 - 2} = \frac{-6}{- 2} =\frac{6}{2}$ )

3 -> -1/3 ( $\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{-7 - -3}{6 - -6}= \frac{-7+3}{6+6}=\frac{-4}{12}=-\frac{1}{3}$ )

(b) If a line is parallel, the slopes will be the same. If they are perpendicular, the slopes will be are negative reciprocals of one another. If they are neither, then their slopes don't match up in any way.

1 & 2 -> Parallel

1 & 3 -> Perpendicular

2 & 3 -> Perpendicular

Note - Since 1 & 2 are parallel, then both 1 and 2 will be perpendicular to 3!
