Solve for c. a=11+4b−4c
astraxan [27]
Hello there!

a = 11 + 4b - 4c
a = 4b - 4c + 11
a + (-a + 4c) = (4b - 4c + 11) + (-a + 4c)
c = \frac{4b - a + 11}{4}

Hope This Helps You!
Good Luck :)

Help please, need to show work.

Answer:

  3.  m∠A < 80°

Step-by-step explanation:

The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.

If we assume that angle measures cannot be zero, then we must have ...

  m∠A +m∠N = 80°

  m∠A = 80° -m∠N

Since m∠N > 0, the measure of angle A must be less than 80°.

This conclusion matches choice 3.

Calculate the gradient of the line using rise/run method.
Lapatulllka [165]

Given:

The graph of line.

To find:

The gradient of the line using rise/run method.

Solution:

We know that the gradient of a line is also known as slope.

Slope=\dfrac{Rise}{Run}

Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.

Rise=-3

Run=2

Now,

Slope=\dfrac{Rise}{Run}

Slope=\dfrac{-3}{2}

The gradient of the line is -\dfrac{3}{2}.

Therefore, the correct option is C.
