Answer:

The equation of the line would be y = .5x + 2.5

Step-by-step explanation:

In order to find this, we must first find the slope of the equation.

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

m = (2 - 3)/(-1 - 1)

m = -1/-2

m = .5

Now that we have the slope, we can use either point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 3 = .5(x - 1)

y - 3 = .5x - .5

y = .5x + 2.5

Given: Isosceles TriangleDEF. The measure of vertex Angle D is four times the measure of each base angle E and F.

777dan777 [17]

Answer:

D = 120° , E = 30° , F = 30°

Step-by-step explanation:

Let D = 4x

Let E&F = x

4x + x + × = 180°[angles in triangle is 180°]

6x = 180°

x = 180/6

x = 30°

E = 30°

F =30°

D =4(30°)

=120°

Find the distance travelled in 1 h 40 min at a speed of 90 km/h

Mariulka [41]

90 km/h is your constant.
1h 40m - 1h since we have 90 km/h.
2/3 of 90 is what we need to find for the 40 min, since 40m/60m = 2/3.
60 is 2/3 of 90.
90 + 60 = 150.
Your distance traveled is 150km.

I need your help again guys!

ANSWER

$x = 13$

EXPLANATION

Use the Pythagoras Theorem to obtain,

${x}^{2} = {12}^{2} + {5}^{2}$

This implies that,

${x}^{2} = 144 + 25$

${x}^{2} = 169$

Take the positive square root of both sides to get,

$x = \sqrt{169}$

$x = 13$
