If x- 7 = 14 then X = 21. so 21-2= 19. :)
-1 cus its -1 becus u -1 so u get -1
Answer:
1 hour.
Step-by-step explanation:
You have to do the total distance /total speed together.
You have to do this to ensure that you are counting how fast they are travelling together.
(450 km) / the sum of their speed (240+210)
450/ (240+210)
=450/ 450
=1
Answer: 1 Hour.
Answer:
2: option 4; 10: option 4; 9: option 4; 6: option 1
Step-by-step explanation:
for 2, the angle of S is equal to Q
for 10, take 180, and subtract all the other numbers to find the last one
for 9, its 4 because the segments are a
A to B, A to C, and B to D
for 6, its 1 because TU is perpendicular (crosses) MN, and MN is perpendicular (will never cross) to PQ
Answer:
Y = 1/2x+2
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
We know the slope
y = 1/2x +b
Substitute the point into the equation
0 = 1/2 (-4) +b
0 = -2+b
b=2
Y = 1/2x+2
