Answer:

y = -2x

Step-by-step explanation:

We have direct variation means

y =kx

We know y and x

10 = k (-5)

Solve for k by diving by -5

10/-5 = k (-5)/-5

-2 = k

y = -2x

Answer:

y = -2x

Step-by-step explanation:

General formula for direct proportion: y = kx, where k is the constant of proportionality. If y = 10 when x = -5, then 10 = -5k, and k = -2.

Then the desired relationship is y = -2x.

Triangle A B C is shown with its exterior angles. Line C B extends through point D. Line B C extends to form exterior angle that

Zarrin [17]

Answer:

m∠ABC = 45°

Step-by-step explanation:

See the attached figure.

As shown in the figure

Line C B extends through point D to form the exterior angle that is 135 degrees.

So, m∠ABD = 135°

But m∠ABC + m∠ABD = 180°

∴m∠ABC = 180° - m∠ABD = 180° - 135°= 45°

Also, we should know that

m∠ABD = m∠BAC + m∠ACB

So, m∠ACB = 135° - 75° = 60°

========================================

<u>Very important note:</u>

If we replaced the location of B and C

SO, m∠ABC = 60° and m∠ACB = 45°

Geometry help anyone!!

Check the picture below.

$\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ h = 6\\ r=3 \end{cases}\implies V=\pi (3)^2(6)\implies \stackrel{in^3}{V=54\pi}$

Geometry Homework Question

mash [69]

Answer:

Distance is 8.485

Midpoint is (3,4)

Step-by-step explanation:

Use the points (-1,7) and (5,1)

Insert them into the equation and solve for D

$D=\sqrt{x} ((5-(-1))^2 + (1-7)^2)\\D=\sqrt{x} ((6)^2 + (-6)^2)\\D=\sqrt{x} (36+36)\\D=\sqrt{x} (72)\\D=8.485$

Insert points into second equation to find midpoint

$(\frac{_1+5}{2} , \frac{7+1}{2}) \\(\frac{6}{2} ,\frac{8}{2} )\\(3,4)$
