Answer:

<h2>f(-7) = -6</h2>

Step-by-step explanation:

Put x = -7 to f(x) = 2x + 8:

f(-7) = 2(-7) + 8 = -14 + 8 = -6

use the substitution method

f(x)= 2x+8

f(-7)= 2(-7)+8

Mutiply first then add

Positive number times negative number = negative number

= -14+8

f(-7)= -6

Answer : f(-7)= -6

Answer:

Angle A = Angle T

Angle B = Angle U

Angle C = Angle V

Step-by-step explanation:

The order that the angles are listed above shows you which angle in the first triangle corresponds to which angle in the other triangle.  It tells you triangle ABC = triangle TUV.  Since A and T are both listed first, they are equivalent.  Angles B and U are both listed second, so they correspond to each other.  And angles C and V are listed last, so they correspond to each other.

Differentiate with respect to t
True [87]

Answer:

\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0

Step-by-step explanation:

We want to differentiate the equation:

x^2-y^3+z^4=1

With respect to <em>t</em>, where <em>x, y, </em>and <em>z</em> are functions of <em>t. </em>

<em />

So:

\displaystyle \frac{d}{dt}\left[x^2-y^3+z^4\right]=\frac{d}{dt}\left[1\right]

Implicitly differentiate on the left. On the right, the derivative of a constant is simply zero. Hence:

\displaystyle 2x\frac{dx}{dt}-3y^2\frac{dy}{dt}+4z^3\frac{dz}{dt}=0
