If you simplify the equation you get y= 3x+7 so m or the slope will be 3 and b or the y intercept is 7
Answer:
The unique solution to the system is (x,y){(-9,-3)}
Step-by-step explanation:
x - y = -6 equation 1
5x + 6y = -63 equation 2
We will find the value of x from equation 1.
x= y-6
Now put the value of x in equation 2.
5(y-6)+6y = -63
5y-30+6y = -63
Combine the like terms:
5y+6y= -63+30
11y = -33
Divide both sides by 11.
11y/11 = -33/11
y = -3
Now put the value y = -3 in x=y-6
x = y-6
x= -3-6
x= -9
Therefore The unique solution to the system is (x,y){(-9,-3)} ....
Answer:

Answer:5.4
Step-by-step explanation:
30% of 18= 18% of 30
10% of 18= 1.8
1.8 times 3=5.4
Answer:
30 and 6
Step-by-step explanation:
Farther = f, Son = s
- f + s = 36
- f + s + 2(f-s) = 84 ⇒ 3f - s = 84
<u>Add up equations:</u>
- 4f = 36 +84
- 4f = 120
- f = 120/4
- f = 30
<u>Find s:</u>
