Find the slope of the line that passes through the following points. (-8,-1) (-4,-2)
lana [24]

Answer:

-1/4

Step-by-step explanation:

We can find the slope of a line given two points by using

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

    = (-2- -1)/( -4 - -8)

    = (-2+1)/(-4+8)

     = -1/4

Help Plz (Emergency)
kompoz [17]

Answer: s = 36

Step-by-step explanation: The key to solving multistep equations is isolating the variable. This is why I first subtracted 14 on each side. This left me with 1/3s=12. Then, to isolate "s" even more, I didvided by 1/3 on each side. This gave me s = 36 as an answer.

To divide by a fraction, use "keep change flip." Keep the first mumber, change division to multiplication, and flip the fraction. I included a picture of me doing this.

If you have any other questions, please feel free to ask :)

(ab² + 13b - 4a) + (3ab² + a +7b)
Natalija [7]

Answer:

4ab² + 20b - 3a

Step-by-step explanation:

This question most likely asks us to simplify the expression, as factoring is not possible...

(ab² + 13b - 4a) + (3ab² + a + 7b),

ab² + 13b - 4a + 3ab² + a + 7b,

ab² + 3ab² + 13b + 7b - 4a + a,

Solution : 4ab² + 20b - 3a

Good answer fast Find the value of y
Radda [10]

Answer: y = 90°

Step-by-step explanation:

55.30786941 = sin-1 (148/180)   round to 55.3°  angle x

34.69213059 = cos-1 (148/180) . round to 34.7°  "angle z" at right

34.7 +55.3 = 90

Sum of All angles of the triangle = 180°  180 -90 = 90

If angle x is 55.7 and angle z is 34.7° Angle y must be 90°

Ratio of inscribed arcs = ratio of chord to diameter
