Answer:

x=-6

Step-by-step explanation:

Given Equation:

                    2(x + 4)= -5 + 1

Solving the Equation for 'x':

                  2(x + 4)= -4

              2(x) + 2(4)= -4\\

                      2x+8=-4

Subtracting '8' both sides:

                        2x=-4-8

                        2x=-12

Dividing by '2' both sides:

                         x=-12/2\\

                           x=-6

The Solution for the equation is:  x=-6

Answer: X = -6

Explanation:
2(x+4) = -5 + 1
2x + 8 = -4
2x = -4 - 8
2x = -12 divide both sides by 2
X = -6

HelppppI need help this benchmark
serious [3.7K]

Answer:

A: -6.5

Step-by-step explanation:

Take two points that we already know are on the line and find the slope

I used:

(4, -10) and (7, -30)

X1 (first x coordinate): 4

Y1 (first y coordinate): -10

X2 (second x coordinate): 7

Y2 (second y coordinate): 30

These appear to be exactly on the graph at a certain point along the line. We can't choose a coordinate pair that isn't on the line at an exact point.

Use (Y2-Y1)/(X2-X1)

(-30-(-10))/(7-4) = (-30 + 10)/3 = -20/3 = approximately -6.67.

The closest answer to that is A.

May someone answer this plzz

D)

6 5/8

or 6.625

Basically

1/8*3 =0.375

1/4 * 3 =0.75

1/2*5 =2.5

and 3/4*4=3

So then,

0.375+0.75+2.5+3=6.625 or 6 5/8 in fraction!

Sin(3x-16)=cos(4x-6) x=?
lapo4ka [179]
sin(3x-16)=cos(4x-6) \\  sin(3x-16)=sin( \frac{ \pi }{2} -(4x-6)) \\ 3x-16=\frac{ \pi }{2} -(4x-6)
3x-16=\frac{ \pi }{2} -4x+6
then :
<u />3x-16=2k \pi +(\frac{ \pi }{2} -4x+6) \\ 7x=2k \pi +\frac{ \pi }{2}+22 \\ x= \frac{2k \pi}{7}  +\frac{ \pi }{14}+ \frac{22}{7}
and \\ 3x-16=2k \pi + \pi -(\frac{ \pi }{2} -4x+6) \\ 3x-16=2k \pi + \pi -\frac{ \pi }{2} +4x-6 \\ -x=2k \pi + \frac{ \pi }{2}+10 \\ x=-2k \pi - \frac{ \pi }{2}-10
