For number 1, you solve it like an equation.
My teacher always says this," Undo what has been done."
It means to do the opposite done to the variable.
3/8x>9
3/8 is being multiplied to the variable so if you do the opposite, you divide 3/8 to each side.
x>24

Number 2
21g>105
You divide each side by 21
g>5

The length of AD is 75. Since opposite sides have the same length, 63 plus 63 is 126. The perimeter is 276, so 276 minus 126 is 150. 150 divided by 2 is 75.

Write an equation of a line in slope-intercept form that passes through (-3,5) and is parallel to y = -6x +1.

katrin2010 [14]

Answer:

a) The equation of the Parallel line to the given straight line is

6 x + y + 13 =0

b) Slope - intercept form

y = - 6 x - 13

c) The intercept - form

$\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1$

x - intercept = $\frac{-13}{6}$

y - intercept = - 13

Step-by-step explanation:

Step(i):-

Given the equation of the straight line

y = -6x +1

6 x + y - 1 = 0

The equation of the Parallel line to the given straight line is

6x + y + k=0 and it passes through the point (-3, 5 )

⇒ 6 (-3 ) + 5 + k =0

⇒ - 18 + 5 + k=0

⇒ -13 + k = 0

⇒ k = 13

The equation of the Parallel line to the given straight line is

6 x + y + 13 =0

Step(ii):-

Slope - intercept form

y = m x + C

y = - 6 x - 13

Step(iii):-

Intercept - form

6 x + y + 13 =0

6 x + y = - 13

$\frac{6x + y}{-13} = \frac{-13}{-13}$

$\frac{6x}{-13} + \frac{y}{-13} = 1$

$\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1$

The intercept - form

$\frac{x}{\frac{-13}{6} } + \frac{y}{-13} = 1$

x - intercept = $\frac{-13}{6}$

y - intercept = - 13
