Answer:

X = -15

Step-by-step explanation:

X/5+2 = -1

Subtract 2 from each side

X/5+2-2 = -1-2

X/5 = -3

Multiply each side by 5

X/5 *5 = -3*5

X = -15

Paralell to y=4x-6 through (12,10)

stiks02 [169]

<u>ANSWER</u>

The line that is parallel to $y=4x-6$ through $(12,10)$ is $y=2x-14$ .

<u>EXPLANATION</u>

The equation that is parallel to the line $y=4x-6$ has a slope that is equal to the slope of this line.

By comparing this equation to the general slope intercept form,

$y=mx+c$ ,this line has slope $m=2$ .

Hence the line parallel to this line also has slope $m=2$ .

Let $y=mx+b$ be the equation of the line parallel to the line

$y=4x-6$

We can substitute $m=2$ to obtain;

$y=2x+b$

If the line passes through the point $(12,10)$ ,then this point must satisfy its equation.

We substitute $x=12$ and $y=10$ to obtain;

$10=2(12)+b$

We this equation for $b$ .

$\Rightarrow 10=24+b$

$\Rightarrow 10-24=b$

$\Rightarrow -14=b$

We substitute this value of $b=-14$ in to $y=2x+b$ to get;

$y=2x+-14$ .

Hence the equation of the line that is parallel to $y=4x-6$ through $(12,10)$ is $y=2x-14$ .

Can someone tell me what x and y would be

TEA [102]

Step-by-step explanation:

20°+120°+I°=180°

I=40°

using sine rule,

I/sin I=x/sinX

12/sin40=x/sin20

x=12sin20/sin40

x=6.4

using similarly and enlargement,

we have, cw/cp=y/120

8/12=y/120

y=80°
