Answer:
x= 20,y= −36
Step-by-step explanation:
3x+2y=−12
2x+y=4
Subtract 2x
from both sides of the equation.
y=4−2x
3x+2y=−12
Replace all occurrences of y
with 4−2x
in each equation.
Tap for more steps...
−x+8=−12
y=4−2x
Solve for x
in −x+8=−12
.
Tap for more steps...
x=20
y=4−2x
Replace all occurrences of x
with 20
in each equation.
Tap for more steps...
y=−36
x=20
The solution to the system is the complete set of ordered pairs that are valid solutions.
(20,−36)
The result can be shown in multiple forms.
Point Form:
(20,−36)
Equation Form:
x=20,y=−36
Answer:
A kite with a 100 foot-long string is caught in a tree. When the full length of the string is stretched in a straight line to the ground, it touches the ground a distance of 30 feet from the bottom of the tree. Find the measure of the angle between the kite string and the ground.

The answer to the first part is 3 1/2 and the answer to the second question is 2/7
Answer:
The length of the missing side of the triangle is represented by the equation:
(6a + 2b - 5) - (2a - 3b) - (a - 3)
= 6a + 2b - 5 - 2a + 3b - a + 3
= 3a + 5b - 2
Answer:
or 
Step-by-step explanation:
Given:
We are to find the values of 
such that these two functions are equal.
Substitute 
.
We get 
Hence for we have the functions to be equal.
Now for 
We see the functions are once again equal.
