Answer:

Step-by-step explanation:

$(\frac{7}{12}) ^{-4} *(\frac{7}{12}) ^{3x} =(\frac{7}{12}) ^{5} \\\\(\frac{7}{12}) ^{-4+3x} =(\frac{7}{12}) ^{5}$

same base;

-4+3x=5

or,3x=5+4

or,x=9/3

x=3

Answer:

We have been given an equation $x^2+9x+20=0$

We will factorize it by middle term splitting.

Step 1: $x^2+5x+4x+20=0$

Taking common factors out by clubing first two terms ad last two terms

Step 2: $x(x+5)+4(x+5)=0$

Step 3: $(x+4)(x+5)=0$

Equating both above factors to zero as:

Step 4: $(x+4)=0\Rightarrow x=-4$

And $(x+5)=0\Rightarrow x=-5$ .

Focus Question: How do you determine whether a real-world context should be

Yakvenalex [24]

Answer:

Simplify the equation as closely as possible to the form of y = mx + b. Check to see if your equation has exponents. If it has exponents, it is nonlinear (exponential). If your equation has no exponents, it is linear.
