Answer:

x=4

Step-by-step explanation:

first you would factor the -2(2x-1). -2x2x= -4x, -2x-1= 2

the equation would then be 5x-4x+2=6

add the x's together which turns the equation to 1x+2=6

minus 2 from both sides of the equation which gives you x=4

What is the slope of the line that passes through the points (3, -4) and (7, 4)?

Andrews [41]

The correct option is: Option (C) 2

Explanation:

The slope formula is = m = $\frac{y_2 - y_1}{x_2 - x_1}$

Insert the values in the above formula:

m = $\frac{4 - (-4)}{7 - 3} = \frac{8}{4} = 2$

Which is Option (C).

For this case we have 6 different terms

Part 4

We can do the following:

$5a^2+a^2+6b-3b+4c-2$

Part 5

And we can simplify on this way:

$6a^2+3b+4c-2$

F(x)=2x+3/4x+5<br>find f(-9)<br>

mylen [45]

$\implies {\blue {\boxed {\boxed {\purple {\sf { f(-9)= 0.48}}}}}}$

$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$f(x) = \frac{2x + 3}{4x + 5} \\$

For $f(-9)$ , put " $-9$ " for every value of " $x$ ".

$↬f( - 9) = \frac{2( - 9) + 3}{4( - 9) + 5}\\$

$↬ f(-9) = \frac{ - 18 + 3}{ - 36 + 5} \\$

$↬ f(-9) = \frac{ - 15}{ - 31}\\$

$↬ f(-9)= \frac{15}{31}\\$

$↬f(-9)= 0.48\\$
