A line crosses the coordinates (-3, 5) and (4, -2). What is the slope-intercept form of the equation of this line?
Sunny_sXe [5.5K]

\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{5})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-2-5}{4-(-3)}\implies \cfrac{-7}{4+3}\implies \cfrac{-7}{7}\implies -1 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-5=1[x-(-3)]\implies y-5=1(x+3) \\\\\\ y-5=x + 3\implies y=x+8

Select expression that is mathematically equivalent to xy−z+ (a - b) X c. y - 2 O
Elden [556K]

Question:

Select expression that is mathematically equivalent to

\frac{x}{y-z} + (a-b)*c

a) x/y - z + (a - b) * c

b) x/(y - z) + (a - b) * c

c) x/y - z + a - b * c

d) x/(y - z) + a - b * c

Answer:

x/(y - z) + (a - b) * c

Step-by-step explanation:

Given

\frac{x}{y-z} + (a-b)*c

Required

Determine its equivalent

Start by writing y - z in bracket;

\frac{x}{y-z} + (a-b)*c

becomes

\frac{x}{(y-z)} + (a-b)*c

When - is used as divide, it is equivalent to /

The given expression can then be rewritten as

x/(y - z) + (a - b) * c

Hence;

<em />\frac{x}{y-z} + (a-b)*c<em> is equivalent to </em>x/(y - z) + (a - b) * c<em />

koban [17]

Answer:

x = 40°

Step-by-step explanation:

using the cofunction identity

cos(90 - x) = sin x , so

90 - x = 50 , then

x = 40

that is sin40° = cos50°
