Answer:
30 = 5y - 4x or 6 + (4x/5) = y (in mx + c = y form)
Step-by-step explanation:
slope =
- 
/ 
- 
now, = 2
= -5
insert the values of these two in the slope formula and equate it with 4/5.
by cross multiplication, obtain equation.
the equation is 30 = 5y-4x.
hope this helps you!
Answer:
5 seconds.
Step-by-step explanation:
Make an equation.
Time in air = x
Time in water = 12 - x
16x + 36 - 3x = 127
13x = 91
x = 7
12 - 7 = 5
Answer:
Move all terms that don't contain x to the right side and solve.
x = 3
Step-by-step explanation:
Answer:
BH = 2
Step-by-step explanation:
The altitude divides the triangle into similar triangles. The ratio of the long side to the short side is the same for all, so ...
AH/BH = BH/HC
4/BH = BH/1
4 = BH² . . . . multiply by BH
2 = BH . . . . . take the square root
Answer:
(59,35)
Step-by-step explanation:
We want to solve the system
-x+2y=11
3x-5y=2
We multiply the top equation by 3 to get:
-3x+6y=33
3x-5y=2
Add both equations to eliminate x
y=35
Put y=35 into top original equation
-x+2(35)=11
This means that
-x+70=11
-x=11-70
-x=-59
x=59
