Answer:
This is a no solution (if you're asking to solve this equation). It will lead to:
20 = 12
Which is NOT equal.
The answer is thus No Solution.
Step-by-step explanation:
4(x + 5) = 4(3 + x) ~ Distribute it
4x + 20 = 12 + 4x ~ Subtract the x
20 = 12 ~ Remaining
20 does NOT equal 12.
The answer is No Solution.
Answer:
HOPE THIS HELPS!!
Step-by-step explanation:
YOU could find it by doing these steps:
Atual Area = ���� square units.
Scale Drawing Area = �� square units.
Value of the Ratio of the Scale Drawing Area to the Actual Area:
Responder:
<em>a) 1
</em>
<em>b) 12
</em>
<em>c) 3
</em>
<em>d) -1 y 3
</em>
Explicación paso a paso:
Dadas las siguientes ecuaciones;
a) x²-x =0
x² = 0+x
x² = x
x = 1
b) -x²+12x = 0
-x² = -12x
x² = 12x
x = 12
c) 3x² - 9x = 0
Suma 9x a ambos lados
3x²-9x+9x = 0+9x
3x² = 9x
3x = 9
x = 9/3
x = 3
d) x²-2x-3 = 0
x²-3x+x-3 = 0
x(x-3)+1(x-3) = 0
(x+1)(x-3) = 0
x+1 = 0 y x-3 = 0
x = -1 y 3
Answer:
y(x)=12*(5)^x
Step-by-step explanation:
y=ab^x, y(0)=12. 12=a.
y=12*b^x, y(2)=300. 12*b^2=300. b^2=25. b=5
