HELPPPPPP MEEEEE y=6x-1 and -2x-3y=-2 USING SUBSTITUTION

1 answer:

7 0

Answer:
x = 4
y =23

work:
plug in the value of Y to -2x-3y=-2. -2x - 3(6x-1) = -2
multiply 3 and the numbers in parenthesis. -2x -18x - 3 =-2
combine like terms (-2x -18x). -20x - 3 = -2
subtract 3 from both sides to isolate the variable. -20x = -5
divide to isolate the variable (-20/-5) x = 4
-
now that we know the value of x, it'll be easy to find Y.
Plug it in to the first equation.
y=6(4)-1
y = 24 - 1
y = 23

so x = 4
and y = 23

hope this helps! :D

Find the distance between the two numbers on a number line. Write your answer as a fraction in simplest form. - 7/9, - 2/9 The d

Nesterboy [21]

The distance between the two points on the number line is of $\mathbf{\frac{5}{9}}$ units.

-------------------------------------------

The distance between two numbers on the number line is given by the subtraction of the greater by the smaller number.
The greater number is $-\frac{2}{9}$
The smaller is $-\frac{7}{9}$ .
The distance is:

$-\frac{2}{9} - (-\frac{7}{9}) = -\frac{2}{9} + \frac{7}{9} = \frac{-2 + 7}{9} = \frac{5}{9}$

Thus, distance of $\mathbf{\frac{5}{9}}$ units.

The type of equation given below is in point-slope form y=1/2x-5 true or false

kykrilka [37]

Answer:

false

Step-by-step explanation:

point slope form : y - y1 = m( x - x1 )

the equation y = 1/2x - 5 does not follow this therefore the answer is false

the equation y = -1/2x - 5 is instead put in slope intercept form , y = mx + b
