Answer:

- 12.4

Step-by-step explanation:

Substitute the given values into the expression

- | 5(- 2) + (- 3) | + | 3(3) + 2(- 4.2) |

= - | - 10 - 3 | + | 9 - 8.4 |

= - | - 13 | + | 0.6 |

= - | 13 | + | 0.6 |

= - 13 + 0.6

= - 12.4

Y=-5x + 22 -2x - 8y = 14

laiz [17]

Step-by-step explanation:

Put the value y.

-2x-8(-5x+22)=14

-2x+40x-176= 14

38x-176 =14

38x = 190

x=5

Now put the value of X to find Y

Y= -5(5)+22= -25+22 = -3

=>X=. 5

=>Y= -3

The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 54 -3. What is the point slope

dangina [55]

Answer:

$y+13=5(x+2)$

Step-by-step explanation:

The correct question is

The slope-intercept form of the equation of a line that passes through point (-2, -13) is y = 5x -3. What is the point slope form of the equation for this line?

we have

$y=5x-3$

This is the equation of the line in slope intercept form

where

the slope is $m=5$

the y-intercept is $b=-3$

Remember that

The equation of the line in point-slope form is equal to

$y-y1=m(x-x1)$

we have

$m=5$

$point\ (-2,-13)$

substitute

$y-(-13)=5(x-(-2))$

$y+13=5(x+2)$
