What is the equation of the following line written in slope-intercept form?

ladessa [460]

Answer:

y = -2/3 x - 13/3

Step-by-step explanation:

We have one point at (-5,-1) and there is another point at (1,-5)

The slope is

m= (y2-y1)/(x2-x1)

= (-5--1)/(1--5)

= (-5+1)/(1+5)

= -4/6

=-2/3

The point slope form of the equation is

y-y1 = m(x-x1)

y--1 = -2/3(x--5)

y+1 =-2/3( x+5)

Distribute

y+1 = -2/3 x -10/3

Subtract 1 from each side

y +1-1 = -2/3 x -10/3 -1

Get a common denominator

y = -2/3 x -10/3 -3/3

y = -2/3 x - 13/3

ein rechteckiger Bauplatz ist 39,5 m lang und 32,5 m breit . wie teuer ist der Grund ,wenn ein Quadratmeter Bauland 185,50 euro

Setler79 [48]

So first you need to find the area of the building site which is:

length x width

39.5m x 32.5m

= 1283.75 $m^{2}$

We know that one square meter costs 185.50 euros.

1 $m^{2}$ = 185.50 euros

1283.75 $m^{2}$ = 238135.625 euros

I'm not exactly that familiar with euros but I'm pretty sure that euros don't have 3 numbers after the point so the two nearest numbers are 238134.86 and 238135.86.

sorry if this is wrong, but I hope it helps, if the euros part is wrong please correct me thanks!

Solve for t. 16 - 2t = t + 9 + 4t please help.

Delvig [45]

Answer:t=1

Step-by-step explanation:

16-2t=t+9+4t

Collect like terms

4t+2t+t=16-9

Combine like terms

7t=7

Divide both sides by 7

7t ➗ 7=7 ➗ 7

t=1
