Which equation represents a line that passes through (-2, 4) and has a slope of 2/5

Mathematics
1 answer:
Ulleksa [173]3 years ago
8 0

Answer:

The equation of line is 5(y-4) = 2( x+2)

2 x-5 y+24=0

Step-by-step explanation:

<u>Step 1:-</u>

Given slope is m = \frac{2}{5} and passes through (-2,4)

y-y_{1}= m(x-x_{1} )

y-4 = \frac{2}{5}(x-(-2))

5(y-4) = 2( x+2)

2 x-5 y+24=0

SHORT RESPONSE Two angles of a triangle have measures of 35° and 80°. Find the values of the exterior angle measures of the tria
Oduvanchick [21]

Answer:

Step-by-step explanation:

Before giving the exterior angles, find the third angle. A triangle (all triangles) measure 180 degrees.

35 + 80 + x = 180

115 + x = 180

x = 180 - 115

x = 65

Exterior angles are supplements of the interior angles.

So the exterior angle to 65 degrees is 180 - 65 = 115

And the exterior angle to 35 degrees is 180-35 = 145

The exterior angle to 80 degrees is 180 - 100 = 80

I don't understand this factorisation <br> a2+ 4a+3​
Tomtit [17]

Answer:

\boxed{\sf (a + 3)(a + 1)}

Step-by-step explanation:

\sf Factor  \: the  \: following:  \\  \sf \implies  {a}^{2}  + 4a + 3 \\  \\  \sf The \:  factors  \: of \:  3 \:  that \:  sum \:  to \:  4  \\ \sf are \:  3  \: and  \:  1. \\ \\  \sf So,  \\   \sf \implies {a}^{2}  + (3 + 1)a + 3 \\  \\  \sf \implies   {a}^{2}  + 3a + a + 3 \\  \\  \sf \implies a(a + 3) + 1(a + 3)  \\  \\ \sf \implies (a + 3)(a + 1)
