What is the constant of proportionality for 6,47.94?

Maurinko [17]

$\boxed{k=7.99}$

<h2>Explanation:</h2>

In this exercise, we have the following point:

$(6,47.94)$

Let's assume that y varies directly as x, so this implies we can writ y as the product of x and some non-zero real constant k. In a mathematical language:

$y=kx$

As you can see, this is the equation of a line whose slope is k and passes through the origin. Therefore, the slope of the line is the constant of proportionality we are looking for:

$Solving \ the \ equation \ for \ k: \\ \\ k\frac{y}{x} \\ \\ Where: \\ \\ x=6 \\ y=47.94 \\ \\ k=\frac{47.94}{6} \\ \\ \therefore \boxed{k=7.99}$

Please help im stuck on this question

VARVARA [1.3K]

Answer:

(12,0)

Step-by-step explanation:

slope m=

$\frac{54-36}{27-22} =\frac{18}{5}$

$y-36=\frac{18}{5}(x-22)\\\\5y-180=18x-396\\\\y=\frac{18x}{5} -\frac{46}{5}$

$0=\frac{10}{5}x-\frac{46}{5}\\\\x=\frac{216}{18} =12$

hope it helps...

Geometry: write formal proofs, ASAP!!!!

liq [111]

Answer:

By the definition of midpoints, AX and CX are congruent. By the definition of segment bisectors, X is the midpoint of BD, and therefore BX and DX are congruent. Since angle AXD and CXB are vertical angles, they are congruent by the vertical angles theorem. By SAS, triangles AXD and CXB are congruent. By CPCTC, angles A and C are congruent. By converse of alternate interior angles theorem, AD is parallel to CB.
