f(x) = -2x + 2

g(x) = (1/3)^x + 1

f(x) = g(x)

-2x + 2 = (1/3)^x + 1

-2x + 2 = 3^(-x) + 1

3^(-x) + 2x + 2 - 1 = 0

3^(-x) + 2x + 1 = 0

We don't know how to solve this, right? But we can analyse the graph. We see that both f(x) and g(x) find each other in two points, (0, 2) and (-1, 4)

So we can say that x = -1 and x = 0 are solutions for this equation.

Step-by-step explanation:

bearings are a measurement in degrees from North

so from point A draw a North line , then draw a line to B ( the position) the angle is the bearing.

as a full turn would be a circle 360⁰ , bearings are written as 3 digits

Help me i'll give brainlist

Answer:

$x=\frac{1}{2}$

Step-by-step explanation:

equation of a circle: $(x - h)^2+(y-k)^2=r^2$

where (h, k) = center and r = radius

From inspection, we can see that the center of the circle = (0, 0)

and the radius = 1

$\implies (x - 0)^2+(y-0)^2=1^2$

$\implies x^2+y^2=1$

Substitute $y=\frac{\sqrt{3}}{2}$ into $x^2+y^2=1$ and solve for $x$ :

$\implies x^2+(\frac{\sqrt{3}}{2})^2=1$

$\implies x^2+\frac{3}{4}=1$

$\implies x^2=\frac{1}{4}$

$\implies x=\pm \sqrt{\frac{1}{4}}$

$\implies x=\pm\frac{1}{2}$

As point P is in quadrant 1, $x$ is positive, so $x=\frac{1}{2}$

72-(63-8) and (72-63)-8

tatyana61 [14]

The Priority is always to parenthesis. It means that in both equations, begin by operating what's inside the parenthesis. Then Subtract what's left.

For the first one you get:
$72 - (63-8)$
$72 - 55$
$17$

For the second one you get:
$(72-63)-8$
$9-8$
$1$

Which mean that The 2 equations are not equal, because $17 \ \textgreater \ 1$
Hope this Helps! :D

Linear function A and linear function B both have the same input values as shown below. Why will the output values for linear fu

podryga [215]

Answer:The initial values of the two functions are different, and the rates of change of the two functions are the same.

Step-by-step explanation:

The values will start out different. When you apply the rate of change, because they have the same rate of change, you don't risk them coming out with the same value if the values ended up being just right, they will always remain different.
