Answer:

Step-by-step explanation:

The triangles are similar, with the smaller one having half the dimensions of the larger one. Then the length of segment (x-1) is half of 42, so ...

x - 1 = 42/2 = 21

x = 22 . . . . . . . add 1 to find x

How do i solve this exponential equation

Novay_Z [31]

Answer:

x = 0 or 1/2

Step-by-step explanation:

Solving an exponential equation of this nature with different bases and coefficients is always a bit of an ad hoc affair. Here, we can divide by the right side expression and make a substitution that turns it into a quadratic.

$3\cdot16^x+2\cdot81^x=5\cdot36^x\\\\0.6\left(\dfrac{4}{9}\right)^x+0.4\left(\dfrac{9}{4}\right)^x=1\\\\\textsf{Let $z=\left(\dfrac{4}{9}\right)^x$}\\\\0.6z+\dfrac{0.4}{z}=1\qquad\text{after substitution}\\\\3z^2-5z +2 = 0\qquad\text{multiply by $5z$ and put in standard form}\\\\(3z-2)(z-1)=0\qquad\text{factor}\\\\z=\dfrac{2}{3}\quad\text{or}\quad z=1\\\\x=\dfrac{\log(z)}{\log(4/9)}=\boxed{\dfrac{1}{2}\quad\text{or}\quad 0}$

Additional comment

A graphing calculator often solves these very nicely, especially when the equation is put into the form f(x) = 0.

Please help me with this

ArbitrLikvidat [17]

Answer:

C and D are correct in my calculations, I'm confused.. ;w;

Step-by-step explanation:

4x + 9 + 79 - x + y = 180

4x - x + y + 79 + 9 = 180

3x + y + 88 = 180

3x + y = 180 - 88

3x + y = 92

y = 92 - 3x

A.) x = 64, y = 50

y = 92 - 3x

(50) = 92 - 3(64)

50 = 92 - 192

50 ≠ - 100

B.) x = 14, y = 152

y = 92 - 3x

(152) = 92 - 3(14)

152 = 92 - 42

152 ≠ 50

C.) x = 23.3, y = 22.1

y = 92 - 3x

(22.1) = 92 - 3(23.3)

22.1 = 92 - 69.9

22.1 = 22.1

D.) x = 14, y = 50

y = 92 - 3x

(50) = 92 - 3(14)

50 = 92 - 42

50 = 50
