Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) you have : x_1 =5 and y_1 =4
m the slope m= -2 (same slope for the line : 2x+y=3 because this lines are parallel and you can write y=-2x+3
an equation for this line is : y-4 = -2(x-5)
Answer:
y = 45
Explanation:
(8)(10)(2)y = 7200
[ Simplify both sides of the equation ]
160y = 7200
[ Divide both sides by 160 ]
160y / 160 = 7200 / 160
y = 45
Check:
8(10)2(45) = 7200
Answer:
131
Step-by-step explanation:
25+24=49
180-49=131
(x1,y1) = (-2,7)
m = -5
(x,y) = (a,2)
Forming the equation,
(y-y1) = m(x-x1)
y - 7 = -5[x - (-2)]
y - 7 = -5x - 10
y + 5x = -3
Putting the values of (x,y) we get,
2 + 5a = -3
5a = -5
a = -1
Answer:
Step-by-step explanation:
Distance=400+200=600km
diplacement=x 200-0km=200km
total distance travelled=400+400=800km
