All u have to do is plug in the values
68) -(4q) = -(4*-3) =-4*3= -12
70) 5P-6= (5*5)-6 =25-6= 19
72) 7q-7p= 7(-3)-7(5) = -21-35= -56
74)2q/(4p) = 2(-3)/4(5)= -6/20= -3/10
The rule for the linear graph is y=mx
Answer:
x = -12
Step-by-step explanation:
4/3x + 12 = - 4 (multiply 3 both side)
4x + 36 = - 12 (minus 36 both side)
4x + 0 = -12
4x = -12 - 36
4x = - 48 (divide both side)
4x ÷ 4 = x
-48 ÷ 4 = -12
Answer: x = -12
Answer:
Yes
Step-by-step explanation:
If you mean the equation
y = 4x + 5
y = x - 4
then yes
Answer:
the sum of the digits of the smallest number 668 = 6+6+8 = 20
Step-by-step explanation:
3 consecutive even number: x, x+2, x+4
4x + 2*(x+4) = 3*(x+2) + 2006
6x + 8 = 3x + 6 + 2006 = 3x + 2012
6x - 3x = 2012 - 8 = 2004
3x = 2004
x = 668
the sum of the digits of the smallest number = 6+6+8 = 20
