Step-by-step explanation:

Mark the end of arrows

  • 2-3/4
  • -4-1/4

So add them

\\ \tt\hookrightarrow 2\dfrac{3}{4}+(-4\dfrac{1}{4})=-1\dfrac{2}{4}

Answer:

B.) 2 3/4 + (-4 1/4) = -1 2/4

Step-by-step explanation:

blue line: forward with positive +2\frac{3}{4}

red line: backward with negative -4\frac{1}{4}

so the number line follows: 2\frac{3}{4} + -4\frac{1}{4} = -1 2/4

What is the equation of the following line written in general form? (The y-intercept is 7.)
Viktor [21]

Answer:

<h2>3x - y + 7 = 0</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

Put the given y-intercept b = 7 and the coordinates of the point (-2, 1) to the equation:

1=-2m+7          <em>subtract 7 from both sides</em>

-6=-2m       <em>divide both sides by (-2)</em>

3=m\to m=3

We have the equation:

y=3x+7

Convert it to the general form Ax+By+C=0:

y=3x+7              <em>subtract 3x and 7 from both sides</em>

-3x+y-7=0           <em>change the signs</em>

3x-y+7=0

Help please!!!!!:( Solve the equation for x. Round your answer to two decimal places. Do not include "x =" in your answer.
svet-max [94.6K]
The solution to the problem is as follows:

If you use Ln you can get rid of e. 

ln(e^0.4x) = ln(0.4) 

0.4x = ln(0.4) 

x = (ln(0.4))/0.4 

<span>x = -2.29

Help quick Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.
Salsk061 [2.6K]

Answer:

k = -3

Step-by-step explanation:

F(x) has a positive slope

g(x) has a negative slope

Let x = -3

The y value goes from 1 to -3

g(x) = k⋅f(x)

-3 = k(1)

-3 = k
