The answer would be: -5
Heres how you solve it!
First, change the x into a 0 so it can be removed.
y+2= -3/4*4
Now with the GCF you can reduce the numbers with 4.
y+2= -3
Then move the 2 to the other side causing it to change its sign into a negative
y= -3-2
Since -3 and -2 are both negative it would be -5
y= -5
then you are left with your answer.
Hope this helps! :3
The solution to the given system of equation is (25/7, 6/7)
<h3>System of equation</h3>
Given the system of equation expressed as:
x= - 4y+7 ........... 1
-2y+3x=9 ...........2
Substitute the equation 1 into 2 into have:
-2y + 3(-4y+7) = 9
-2y + 3(-4y) + 3(7) = 9
-2y - 12y + 21 = 9
Collect the like terms
-14y = 9- 21
-14y = -12
y = 6/7
Substitute y = 6/7 into equation 1;
x =-4y + 7
x = -4(6/7) + 7
x= -24/7 + 7
x = -24+49/7
x = 25/7
Hence the solution to the given system of equation is (25/7, 6/7)

Answer:
3/5 mph
Step-by-step explanation:
Answer: 750 Joules.
Step-by-step explanation:
Use the equation: K = 1/2 x m x s^2
1/2 x 60 = 30.
30 x (5 x 5) 25 = 750
Lance's kinetic energy when he runs at this speed is 750 Joules.
