Answer:

x =23

Step-by-step explanation:

-4.2x + 31.5= -65.1

Subtract 31.5 from each side

-4.2x + 31.5-31.5= -65.1-31.5

-4.2x =-96.6

Divide each side by -4.2

-4.2x/-4.2 = -96.6/-4.2

x =23

I don't understand what you need.

But,

5 + 3 = 8

56/8 = 7

Use point slope form to write the lines with the given slope and point in slope intercept form.m= -1(-5,-4)
lara31 [8.8K]

The slope point form is

y-y1=m(x-x1)

m is the slope

x1, y1 are the coordinates of a point on the line

The slope of the line is -1

m = -1

point (-5, -4) lies on the line

x1 = -5 and y1 = -4

Let us substitute them in the form above

y-(-4)=-1(x-\lbrack-5\rbrack)

Remember (-)(-) = (+)

y+4=-1(x+5)

The equation of the line in the slope-point form is y + 4 = -1(x + 5)

200 - [ ( 50 - 4 ) × 3 + 5 ]
= 200 - [ 46 × 3 + 5 ]
<Put brackets around the 2 number that enclose the times sign as a reminder to do that first>
= 200 - [ ( 46 × 3 ) + 5 ]
= 200 - [ 138 + 5 ]
= 200 - (143)
= 57

Hope this helps!
