Which of the following are equations for the line shown below? Check all that apply.
Nuetrik [128]

Answer: D. y+4=(x+2)

Step-by-step explanation: Once you subtract 4 from both sides, in order to solve for y (as the equation needs to be in the slope-intercept form, otherwise known as y=mx+b), you end up with y=x-2, which is the right answer. It is the correct answer because the y-intecept shown in the equation matches what is on the graph, in addition to the fact that the slope is just x.

Which set of graphs can be used to find the solution set to 3e* &gt; &gt;-x?
kobusy [5.1K]

The attached graph represents the solution set of 3e^x > \frac 12^x

<h3>How to determine the graph?</h3>

The complete options are not given.

So, I would plot the graph that represents the solution set

The inequality is given as:

3e^x > \frac 12^x

Start by splitting the inequalities as follows:

f(x) > 3e^x

g(x) > \frac 12^x

The above means that we plot the graphs of f(x) and g(x) to represent the solution set

Determine the discriminant of x2 = 4. <br><br> A. 17 <br> B. 16 <br> C. -15 <br> D. -10
tino4ka555 [31]
The discriminant is b<span>²-4ac
We can rewrite x</span>² = 4 to x<span>² + 0x - 4 = 0
So a = 1, b = 0, c = -4
</span>Δ = 0 - 4 * 1 * -4
Δ = 16
The answer is B

Which of the following is true about the system 4/3x−2/5y=2 and 3x−2y=−1?
lilavasa [31]

Equation 1 is \frac{4}{3}x -\frac{2}{5}y =2 ,

Equation 2 is [/tex] 3x-2y = -1 [/tex]

for first equation LCD= 3 *5 = 15 , So we multiply whole equation by 15

\frac{4}{3} *15x -\frac{2}{5}*15 y =2*15

20x - 6y = 30

Now multiply second equation by -3 , to make the coefficient of y equal and opposite , so that we can apply the elimination method

-9x+6y = 3

Add both the equations

20x -9x -6y +6y = 30+3

11x= 33

Divide both sides by 11

x=3

Plug in any one of the equation we get

3(3) -2y = -1

9 - 2y = -1

subtract 9 from both sides

-2y = -10

divide both sides by -2

y=5

So the solution is x= 3 , y= 5

Which means

a. The system is consistent and independent. TRUE
