Answer: y = -5; x = -2
Step-by-step explanation:
- 5y – 10x=45
- 3y + 10x = -5
Combining both equations
-8y = 40
y= 40/ -8
y = -5
Substitute y = -5 into any of the equations to get the value of x
-5 (-5) - 10x = 45
25 -10× = 45
-10x =45 -25
-10× = 20
Divide both sides by -10
x = -2

The motion of the ball as described above is an example of geometric sequence. A geometric sequence is that which the value of the succeeding terms share a common ratio. From the given, since the ball is dropped in 10 ft from the ground, this is the a1 or or the first term.
Answer:
Explanation:
g(x) = 3/4x + 7
g(x) = -2
=> 3/4x + 7 = -2
3/4x = -9
x = -9 x 4/3
x = -12
Answer:
3
Step-by-step explanation:
Let's isolate x on one side.
2x - x - 2/3x = -8+5+4
1/3x=1
x=3
