4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6

What is the distance between point A(-3,2) and point B(5,-1)

Gnoma [55]

Remember the distance formula

$S=\sqrt{(5+3)^{2}+(-1-2)^{2} }$

$S=\sqrt{8^{2}+(-3)^{2} }$

$S=\sqrt{64+9}$

$S=\sqrt{73}$

3.Solve the system of equations: X-4y=-22 x+4y=10

laila [671]

Answer:

-0.5

Step-by-step explanation:

Use the simultaneous equations method:

x - 4y = 6

3x + 4y = 10

Add these two equations together to cancel out 'y':

4x = 16

Divide both sides by 4:

x = 4

substitute this value into one of the equations:

(4) - 4y = 6

Subtract 4 from both sides:

- 4y = 2

Divide both sides by -4:

y = -0.5

goodluck!
