Assuming is the inverse of the expression.

as you'd know, we first off do a quick switcharoo on the variables, and then solve for "y", so, let's do so,

\bf \stackrel{f(x)}{y}=x^2-16\qquad inverse\implies \boxed{x}=\boxed{y}^2-16
\\\\\\
x+16=y^2\implies \sqrt{x+16}=\stackrel{f^{-1}(x)}{y}

TEA [102]

Given the figure, both triangles are congruent.

Using the Side Angle Side (SAS) theorem, we can say thath both triangles are congruent.

The Side Angle Side theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, both triangles are congruent.

Here have two given sides and the angles opposite each other(vertical angles) are congruent. Thus, both triangles are congruent.

ANSWER:

Yes

Mark wants to invest 10,000 in a cd for at least 10 years the first choice is a cd that pays 4% annually and uses simple interes
weqwewe [10]

Answer: 14000

Step-by-step explanation:

From the question, the first thing is to first calculate the simple interest (S.I). This will be:

S.I = (principal × rate × time)/100

where principal = 10,000

rate = 4%

time = 10 years

Simple interest = (10,000 × 4 × 10)/100

= 400000/100

= 4000

The total value after 10 years will be th addition of the amount invested and the interest. This will be:

= 10,000 + 4000

= 14000

Directions: Graph each equation by using the y-intercept and slope( make sure too show your work)
vova2212 [387]

Given:

The equation of a linear function is:

y=-\dfrac{2}{3}x-1

To find:

The y-intercept and slope of the given equation, then draw the graph of the equation.

Solution:

Slope intercept form of a line is:

y=mx+b             ...(i)

Where, m is the slope and b is the y-intercept

We have,

y=-\dfrac{2}{3}x-1        ...(ii)

On comparing (i) and (ii), we get

m=-\dfrac{2}{3}

b=-1

Therefore, the y-intercept is -1 and the slope of the line is -\dfrac{2}{3}.

It means the graph intersect the y-axis at point (0,-1) and having slope -\dfrac{2}{3}. So, the graph of the equation is shown below.
