$5x - (x - 2) \geq 2x - 4(x - 8)\\5x - x + 2 \geq 2x - 4x + 32\\5x - x - 2x + 4x \geq 32 - 2\\6x \geq 30\\x \geq 5\\$

Interval notation: $x \in \lbrack 5, \infty \rangle$

Solve each equation <br>2x + 2+x= -22

vodomira [7]

Answer:

-8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x+2+x=−22

(2x+x)+(2)=−22(Combine Like Terms)

3x+2=−22

Step 2: Subtract 2 from both sides.

3x+2−2=−22−2

3x=−24

Step 3: Divide both sides by 3.

−24

x=−8

WILL GIVE 40 BRAINLY

irina [24]

Answer:

$(3,2)$

Step-by-step explanation:

The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

$y=-2x+8\\y=x-1$

In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.

$x-1 = -2x + 8$

Now solve using inverse operations,

$x -1 = -2x + 8\\+2x\\\\3x - 1 = 8\\+1\\\\3x =9\\/3\\\\x = 3$

Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).

$y=x - 1\\$

Substitute,

$y=(3)-1$

Solve,

$y=2$

Thus, the answer to this system of equations is the following, $(3,2)$ .

A fisherman can row upstream at 4mph and downstream at 6mph. He started rowing upstream until he got tired and then started down

ikadub [295]

Total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles

What is the slope of this line

kifflom [539]

Answer:

3/4

Step-by-step explanation:

We can find the slope from the two points given

m = (y2-y1)/(x2-x1)

= (1- -2)/(2 - -2)

= (1+2)/(2+2)

= 3/4
