what is the y- coordinate of the y- intercept of the line that passes through the points (-4,-4) and (4,8)
erastova [34]
\bf \begin{array}{ccccccccc}&#10;&&x_1&&y_1&&x_2&&y_2\\&#10;%  (a,b)&#10;&&(~ -4 &,& -4~) &#10;%  (c,d)&#10;&&(~ 4 &,& 8~)&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies &#10;\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{8-(-4)}{4-(-4)}\implies \cfrac{8+4}{4+4}\implies \cfrac{12}{8}\implies \cfrac{3}{2}

\bf \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}y-(-4)=\cfrac{3}{2}[x-(-4)]&#10;\\\\\\&#10;y+4=\cfrac{3}{2}(x+4)\implies y+4=\cfrac{3}{2}x+6\implies y=\stackrel{slope}{\cfrac{3}{2}}x\stackrel{y-intercept}{+2}

notice the slope-intercept form, that's the y-coordinate.

iVinArrow [24]

Answer:

  • ≈ 33.445 m²

Step-by-step explanation:

<u>You need to convert square yards to square meters:</u>

  • 1 yd = 0.9144 m
  • 1 yd² = (0.9144)² m² ≈ 0.8361 m²

<u>Multiply this by 40 to get the amount you need:</u>

  • 40*0.8361 m² ≈ 33.445 m²

What is the length of side EF in the triangle? Please give a step by step explanation, I'm having lots of trouble finding the so
wel

Answer:

EF = 8.8 cm

Step-by-step explanation:

In the given right angled ΔDEF, DE is the hypotenuse while EF and DF are adjacent sides. So that applying the Pythagoras theorem, we have;

/hyp/^{2} = /adj1/^{2} + /adj2/^{2}

/DE/^{2} = /EF/^{2} + /DF/^{2}

/16.2/^{2} = /EF/^{2} + /13.6/^{2}

262.44 = /EF/^{2} + 184.96

/EF/^{2} = 262.44 - 184.96

          = 77.48

EF = \sqrt{77.48}

     = 8.8023

EF = 8.8 cm

The length of side EF is 8.8 cm.
