Rewrite as y-x=-2
intercepts are 2 and -2

so, draw

Arrange in slope intercept form.....
2y = 2x -4
y = x - 2

So, the line would go up......crossing the y axis at -2.........hope this helps

E=6c^2-2c-1<br> F=-4c^2+7c+5<br> E+F=

kifflom [539]

Answer:

E + F = 2c^2 + 5c + 4

Step-by-step explanation:

E=6c^2-2c-1

F=-4c^2+7c+5

E+F= 6c^2 -2c -1 + -4c^2 + 7c + 5

E + F = 6c^2 - 4c^2 - 2c + 7c - 1 + 5

E + F = 2c^2 + 5c + 4

What is the limit of the function?

SCORPION-xisa [38]

Answer:

Step-by-step explanation:

i think both are false.

$\lim_{x \to - \infty} f(x)= \lim_{x \to- \infty} (4x^8-3x^7+2x-11)\\ = \lim_{x \to - \infty} x^8(4-\frac{3}{x}+\frac{2 }{x^7} -\frac{11}{x^8})\\=-\infty(4-0+0-0)\\=-4 \infty\\=- \infty\\similarly other$

Now, evaluate f (x) = 2x4 – 4x3 – 11x2 + 3x – 6 for x = –2.<br><br> f (–2) =

lorasvet [3.4K]

Answer:

f(- 2) = 8

Step-by-step explanation:

To evaluate f(- 2) substitute x = - 2 into f(x) , that is

f(- 2) = 2 $(-2)^{4}$ - 4(- 2)³ - 11(- 2)² +3(- 2) - 6

= 2(16) - 4(- 8) - 11(4) - 6 - 6

= 32 + 32 - 44 - 12

= 64 - 56

= 8

The table below represents the total cost of leasing a car at the end of each month. Write an equation in slope-intercept slope

exis [7]

Answer:

$y\text{ = 359x + 1500}$

Explanation:

Here, we want to write an equation in slope-intercept form

What we need to do is to select two points to use, then apply the two-points form

We have that as:

$\frac{y_2-y_1}{x_2-x_1}\text{ = }\frac{y-y_1}{x-x_1}$

We pick any two points as (x1,y1) and (x2,y2)

We have that as:

(1,1859) and (8,4372)

Substituting the values, we have it that:

$\begin{gathered} \frac{4372-1859}{8-1}\text{ = }\frac{y-1859}{x-1} \\ \\ \frac{2513}{7}=\text{ }\frac{y-1859}{x-1} \\ \\ 359\text{ = }\frac{y-1859}{x-1} \\ \\ 359(x-1)\text{ = y-1859} \\ 359x-359\text{ = y-1859} \\ 359x-359+1859\text{ = y} \\ 359x-359+1859\text{ = y} \\ y\text{ = 359x+ 1500} \end{gathered}$
