Answer:
(-3/10,-16/5)
Step-by-step explanation:
One way to solve a system of equations is by elimination. We can take one equation and subtract the other equation from it to cancel out on of the variables making the equation into something we can solve. In this case the Y's will cancel out because we have 1 Y in each equation
-4x+y=-2
6x+y=-5 subtract
-4x-6x=-10x
y-y=0
-2-(-5)=3
so our equation is -10x=3 and we can solve for x giving us x=-3/10
now we can plug -3/10 in for x into either of the original equations and solve for Y
y+5=-6(-3/10)
y+5=9/5
y=-16/5
so our answer is (-3/10,-16/5)

Answer:
1/4*(d-2) . I really hope this helps you. :)
A= a^2+2a\square root{\frac{a^2}{4}}+h^2
a=base=8
h=height=7
A=surface area
A=177
Answer:
20 hours
Step-by-step explanation:
Given : Distance = 240 km
Speed = 12km/hr
To Find:How long does it take to travel 240 km at a constant speed of 12 km/h?
Solution:
We need to calculate the time taken to travel 240 km at a constant speed of 12 km/h
Formula : 
Thus it take 20 hours to to travel 240 km at a constant speed of 12 km/h
I really hope this is right
