Answer:

Slope = 6

Step-by-step explanation:

Slope = $\frac{y^{2}-y^{1} }{x^{2}-x^{1} } =\frac{1-(-5)}{-1-(-2)}=\frac{1+5}{-1+2}=\frac{6}{1}=6$

Answer:

Step-by-step explanation:

s + 3s = 4s
t + 3t = 4t

If 4s is 2 more than 4t, then:

4s = 2+ 4t
4s - 4t = 2
4s/4 - 4t/4 = 2/4
s - t = 1/2

The interior angle measures of a convex pentagon are consecutive multiples of 4. find the measure of each interior angle.

lawyer [7]

Answer:

100°, 104°, 108°, 112°,116°

Step-by-step explanation:

Let the smallest angle be $4x$ . Since, the interior angles are consecutive, the other angles are $4(x+1)$ , $4(x+2)$ , $4(x+3)$ and $4(x+4)$ .

Sum of interior angles = 540°

$4x+4(x+1)+4(x+2)+4(x+3)+4(x+4)=540$ °

$20x+40=540$ °

$20x=(540-40)$ °

$20x=500$ °

$x=(500/20)$ °

$x=25$

Using the value of x to calculate the angles:

$4x=4*25=100$ °

$4(x+1)=4*26=104$ °

$4(x+2)=4*27=108$ °

$4(x+3)=4*28=112$ °

$4(x+4)=4*29=116$ °
