VashaNatasha [74]3 years ago
6 0

Answer:

ONE: x = 10

Step-by-step explanation:

3x + 6 = -1 - 3 + 4x

3x + 6 = -4 + 4x       |subtract 6 from both sides

3x = -10 + 4x      |subtract 4x from both sides

-x = -10      |change the signs

x = 10

Answer:

<em>Answer</em><em> </em><em>is</em><em> </em><em>given below with explanations</em><em>. </em>

Step-by-step explanation:

by \: simplifying \: the \: given \: expression \: using \:  \\ law \: of \: exponents \: we \: get \\  \frac{15 {x}^{15}  {y}^{ - 3}  {z}^{4} }{18 {x}^{18}  { {y}^{4}  {z}^{ - 4} }^{} }  \\   = \frac{5  \: {x}^{ - 3}  {y}^{ - 7} {z}^{8}  }{6}  \\ we \: may \: also \: write \: as \\  =  \frac{5 {z}^{8} }{6 {x}^{3}  {y}^{7} }

formulae \: used  \ \: : \\  \frac{ {x}^{m} }{ { {x}^{n} }^{} }  =  {x}^{m - n}  \:  \:  \: and \\  {x}^{ - m}  =  \frac{1}{ {x}^{m} }

Determine the intercepts of the line.
iogann1982 [59]

Answer:

y-intercept: (0,5)

x-intercept: (5/2,0)

Step-by-step explanation:

-4x+7=2y-3

-4(0)+7=2y-3

0+7=2y-3

7=2y-3

10=2y

5=y <-- y-intercept: (0,5)

-4x+7=2y-3

-4x+7=2(0)-3

-4x+7=-3

-4x=-10

x=\frac{5}{2} <-- x-intercept: (5/2,0)
