value of x= -3 and value of y = -12
Solution set is (-3,-12)
Step-by-step explanation:
We need to solve the system of equations using substitution
The system of equations are:
Solving:
Let
Solving:
Putting value of y from equation 1 into equation 2
So, value of x = -3
Now, putting value of x into equation 1 and find value of y
Value of y = -12
So, value of x= -3 and value of y = -12
Solution set is (-3,-12)

Answer: 9 elm trees were removed.
Step-by-step explanation:
Let x represent the number of elm trees removed.
The total number of elm trees in the park is 22. Elm leaf beetles have been attacking the trees. After removing several of the diseased trees, there are 13 healthy elm trees left. The equation to find the number of elm trees that were removed would be
x + 13 = 22
Subtracting 13 from the left hand side and the right hand side of the equation, it becomes
x + 13 - 13 = 22 - 13
x = 9
Answer:
-4x-34
Step-by-step explanation:=−4x+−28+−6
=(−4x)+(−28+−6)
=−4x+−34
Answer:
The average acceleration of the cyclist was 0.6 m/s².
Step-by-step explanation:
Acceleration:
The rate change of velocity per unit time is call the acceleration of the object.
u= initial velocity
v= final velocity
t= time taken change of velocity.
During the final 5 seconds of a race cyclist increased her velocity from 4m/s to 7 m/s
Here v= 7 m/s and u=4 m/s t=5 seconds
=0.6 m/s²
The average acceleration of the cyclist was 0.6 m/s².
