Answer:

5

Step-by-step explanation:

60 x + 70(x+1)=330

60x+70x+70=330

130x=260

x=2

x+1=3

Use Cramers Rule to solve the system <br> 2x - 3y = 11<br> -6x + 8y = 34

Nastasia [14]

Step-by-step explanation:

given :

2x - 3y = 11

-6x + 8y = 34

find : the solutions of the system by using Cramers Rule.

solutions:

in the matrix 2x2 form =>

[ 2 -3] [x] [11]

=

[-6 8] [ y] [34]

D =

| 2 -3 |

|-6 8 |

= 8×2 - (-3) (-6)

= 16-18 = -2

Dx = | 11 -3 |

| 34 8 |

= 11×8 - (-3) (34)

= 88 + 102

= 190

Dy = | 2 11 |

|-6 34 |

= 2×34 - (-6) (11)

= 68 + 66

= 134

x = Dx/D = 190/-2 = -95

y = Dy/D = 134/-2 = -67

the solutions = {-95, -67}

Hello!

$\large\boxed{\text{ slope = -3}}$

Use the slope formula to solve for the slope of the line (m):

$m = \frac{y^{2} -y^{1} }{x^{2} -x^{1} }$

We can plug in the points (0, 4) and (1, 1) to solve:

$m = \frac{1-4}{1-0}= \frac{-3}{1} = -3$

Therefore, the slope of the line is -3.

“Solve each inequality and graph its solution. Show work.”

Cloud [144]

Answer:

$p$ or $p >6$

Step-by-step explanation:

Given

$|-5-p| > 11$

Required

Solve and graph

$|-5-p| > 11$

Remove absolute bracket

$-5 - p > 11$ or $-5- p$

Solve for p

$-p > 11 + 5$ or $-p < -11 + 5$

$-p > 16$ or $-p < -6$

Divide by -1

$p$ or $p >6$
