Answer: X equals B.

Step-by-step explanation: all the degrees in a triangle add to be 180, so add up the given angles and subtract from 180 to get the missing angle.

Answer:

Step-by-step explanation:

(180° - 105°) + 55° + x = 180°

75° + 55° + x = 180°

x + 130° = 180°

x = 180° - 130°

x = 50°

Answer:

y=-3x+5

Step-by-step explanation:

concepts: y=mx+b is slope intercept equation formula

m=slope

b= y intercept

Therefore we need to find the slope and y intercept

first find slope

m= $\frac{y2-y1}{x2-x1}$

let y2 be 2

let y1 be -4

let x2 be 1

let x1 be 3

$\frac{2-(--4)}{1-3}$

6/-2 = -3

m=-3

slope is -3

y= -3x+ b

we need find y intercept now

just plug in (1,2) into that equation

2=-3(1)+b

b=5

y=-3x+5

If graphed in the plane, would the line y=5x-2 pass through the point (4,15)

yulyashka [42]

Answer:

Step-by-step explanation:

Using substitution, subs in the points given

(15) = 5(4) - 2

15 = 20 - 2

Because the 2 sides are NOT equal the line would not pass through the point

(02.02)A train can travel 744 miles in 3 hours. What is the unit rate that this train is traveling per hour? _____ miles per hou

Fynjy0 [20]

If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.
