Solve the equationx+5+x+x+
x+x+x+5=
xx6xx( this is only addition not multiplication)
Use 0-9 only once figure out the x

Answers

note:
3x means 3 times x or x+x+x
xx means x times x or x(x)

so
x+5+x+x+x+x+x+5=x+x+6+x+x
add like terms
6(x)+10=4(x)+6
not sure about the 0-9 part so I will disreagrd for now, please ask for correction later

6x+10=4x+6
subtract 4x from both sides
2x+10=6
subtract 10 from both sides
2x=-4
divide both sides by 2
x=-4/2=-2 (divide or multiply by different signs and get negative)
x=-2

1) What is the slope of the line that passes through the pair of points (2, -3) and (5, -4)2) Write an equation in point-slope form for the line through the given point with the given slope. (3, -4) Slope = 6

Answers

QUESTION 1: (2, -3) and (5, -4)

Y2 -Y1

X2 -X1

-4 - -3

5 - 2

= - 1

QUESTION 2: (3, -4) Slope = 6

About Point Slope Form:

Y -Y1 = m (x - X1)
m is the slope
Y1 & X1 is a point on the line
The form allows you to identify the slope & the point on the line

Y - -4 = 6 (x - 3)
