Answer:Nonlinear

Step-by-step explanation:

The ratio is 1:8 meaning if you divide the second part by 8 it should get you the first part but 16/8 is 2 not 3 therefore it is not linear

It tells you they are similar. This means the angles are the same, and the sides are proportionate.

Look at the 12 and 4 at the very bottom. This tells you the ratio of the sides. Since 12 / 4 = 3, you can find y with 2 * 3 which is 6.

From that, you also know that 3z = 3y - 2. Substitute the value of y in and you can find z.

Corresponding angles are exactly the same. which means, (3x)° = 100°

You should get x = 33 1/3, y = 6, z = 5 1/3

Answer:

7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

learn the table of how these symbols work.

in this case its two minuses which make plus so 2+5=7

Notice that the square root is accompanied with ^2 and can be simplified:

This works because 4x^4 = (2x^2)^2

[tex]\sqrt{(2x^{2})^{2} * (256y^{8})^{2} }[/tex]

Remove the square root:

[tex]2x^{2} (256y^{8} )[/tex]

Calculate the product:

[tex]512x^{2} y^{8}[/tex]

This is your answer after simplification.

Answer:

do RN/RM first which will be 95/73 which is 1.30 and use this to multiply 47 which is 47*1.3   61.1

ANSWER = D.

I first got the variable of 1.3 which is multiply that by RM to get RN and then useing that logic you multiply 1.3 by MP to get QN

Answer:

16.4

Step-by-step explanation:

sin 55 = x/20

x = 20 sin 55 = 16.4

Step-by-step explanation:

y - y = 2x + 150 -( - 8x - 30 )

0 = 2 x + 150 + 8 x + 30

0.= 10x + 180

- 180 = 10 x

-180/10 = x

-18 = x

then y = 2 (-18) + 150

y = -36 + 150

y = 114

plz mark my answer as brainlist plzzzz.hope this will be helpful to you.

Answer:

x=2, y= -2

Step-by-step explanation:

Answer:

-10x+y=-22---------equation 1

-8x+y=-18----------equation 2

subtract eqn 1 and 2

-10x+y=-22

-8x+y=-18

(+) (-) (+)

__________

-2x=-4

or, x=2

put the value of x in equation 1 we get

-10×2+y=-22

y=-22+20

or, y = -2

therefore x=2 and y=-2 ans.

Answer:

R=34

Step-by-step explanation:

As, pythoreon therom states = a2 + b2= c2

a= 16, 16^2 = 256

b= 30, 30^2 = 900

c2= 900+256

c2 = 1,156

c= 34

So, 16^2 + 30^2 = 34^2

Step-by-step explanation:

[tex] \sin(45) = \frac{x}{5} \\ \frac{1}{ \sqrt{2} } = \frac{x}{5} \\ x = \frac{5}{ \sqrt{2} } = 3.535[/tex]

[tex] \sin(45) = \frac{y}{5} \\ y = \frac{5}{ \sqrt{2} } = 3.535[/tex]

45-45-90 equation is x-x- x square root of 2

Answer:

Step-by-step explanation:

(-2 - 2)/(-4 + 2)= -4/-2= 2 is the slope

y - 2 = 2(x + 2)

y - 2 = 2x + 4

y = 2x + 6 is the equation

Answer:

The slope is 2

Answer:

Angle <E is approximately 40 degrees, and angle <D is approximately 50 degrees

Step-by-step explanation:

Since angle <F is clearly 90 degrees, we can find angle E using the cosine function that relates the adjacent side to the angle with the hypotenuse:

[tex]cos(\theta)=\frac{adj}{hyp} \\cos(E)=\frac{6.5}{8.5}\\E = arccos(\frac{6.5}{8.5})\\E\approx 40.12^o[/tex]

And we use the sin function to deal with angle <D:

[tex]sin(\theta)=\frac{opp}{hyp} \\sin(D)=\frac{6.5}{8.5}\\D = arcsin(\frac{6.5}{8.5})\\D\approx 50^o[/tex]

Answer:

8(n/4)

Step-by-step explanation:

Answer:

the answer is 11 years

Step-by-step explanation:

if school A is graduated 50/years,

the graduated in 11 years is 550

added of graduated 1,700 in 550 is 2,250

if school B is graduated 150/years,

the graduated in 11 years is 1650

added of graduated 600 in 1650 is 2,250

so School A and B is to be equal in 11 years

Answer:

Move the dot at the axis one to the left and one down move the other dot to (7,0)
