Answer:

(a) f(x) = -3x +6

Step-by-step explanation:

Solve for y, then write as a function.

3y +9x = 18 . . . . . . given

y +3x = 6 . . . . . . . . divide by 3

y = -3x +6 . . . . . . . subtract 3x

f(x) = -3x +6 . . . . . written using function notation

Cuanto es la respuesta de -126=14k?

N76 [4]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \text{k = - 9}}}}}$

Step-by-step explanation:

$\star{ \text{ - 126 = 14k}}$

$\text{step \: 1 \: : Intercambia los lados de la ecuación}$

$\hookrightarrow{ \sf{14k = - 126}}$

$\text{step \: 2 : Divide ambos lados por 14}$

$\hookrightarrow{ \sf{ \frac{14k}{14} = \frac{ - 126}{14}}}$

$\text{step \: 3 \: : Calcular}$

$\hookrightarrow{ \sf{k = - 9}}$

$\text{el valor de k es - 9}$

------------------------------------------------------------

Translation in English:

Step 1 : Swap the sides of the equation

Step 2 : Divide both sides by 14

Step 3 : Calculate

In rhombus ABCD, diagonals AC and BD meet at point E. If the measure of angle DAB is 46 degrees, find the length of EB.

slamgirl [31]

Answer:

EB ≈ 1.563 in

Step-by-step explanation:

The diagonals of a rhombus divide the figure into four congruent right triangles. Angle DAB is bisected by EA, so angle EAB is 46°/2 = 23°. EB is the side opposite, so the relevant trig relation is ...

Sin = Opposite/Hypotenuse

sin(EAB) = EB/AB

EB = (4 in)sin(23°) . . . . . . multiply by the hypotenuse

EB ≈ 1.563 in

A line contains the two points plotted in the coordinate plane below.

Andrew [12]

Answer:

The slope would be 3.

Step-by-step explanation:

The formula for finding slope is $\frac{y1-y2}{x1-x2}$
We can plug these numbers into the equation by doing $\frac{1--5}{2-0}$
1--5 is equal to 1+5, which is 6.
2-0 is equal to 2.
$\frac{6}{2}$ is 3, which is how you get your answer.
I hope this helps! :)
