Answer:

• For y-intercept [ x = 0 ]

{ \rm{y =  - 2x - 21}} \\  \\ { \rm{y = ( - 2 \times 0) - 21}} \\  \\ { \rm{y =  - 21}} \\  \\ { \boxed{ \rm{ \: y - intercept :  \: (0, \:  - 21) \: }}}

• For x-intercept [ y = 0 ]

{ \rm{y =  - 2x - 21}} \\  \\ { \rm{0 =  - 2x - 21}} \\  \\ { \rm{2x =  - 21}} \\  \\ { \rm{x =  - 10.5}} \\  \\ { \boxed{ \rm{x -intercept :  \: ( - 10.5, \: 0) \: }}}

forsale [732]

Answer:

\frac{4}{15}  +  \frac{3}{5}  -  \frac{2}{3}

\frac{4 \times 1}{15 \times 1}  +  \frac{3 \times 3}{5 \times 3}  -  \frac{2 \times 5}{3 \times 5}

\frac{4}{15}  +  \frac{9}{15}  -  \frac{10}{15}

\frac{4 + 9 - 10}{15}

\frac{13 - 10}{15}

\frac{3}{15}

\frac{1}{5}

How do i do this pls help me
Delvig [45]

Answer:

y =  \frac{1}{7} x + 7

Step-by-step explanation:

x-7y = -49

i) move x to the right-hand side and change its sign

-7y = -49-x

ii) change the signs on both sides of the equation

7y = 49+x

iii) divide both sides of the equation by 7

\frac{7y}{7}  = \frac{49}{7}  +  \frac{x}{7}

y = 7 +  \frac{1}{7}  x

iv) use the commutative property to reorder the terms

* commutative property: a+b = b+a

y =  \frac{1}{7} x + 7
