Find the equation of a line that is perpendicular to the line y = 1/9x +6 and contains the point (-7,0).

Answer:

S=32.5

W=97.5

Step-by-step explanation:

S=speed of plane in still air

W=speed of wind

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

3(S+W)=130

6(S-W)=130

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

S+W=43.33333...

S-W=21.66666...

2S=64.999...

S=32.5(simplified)

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

32.5+W=130

W=97.5

Greetings from Brasil...

Comparing the distances AB and A'B ', we notice that AB = 3 and A'B' '= 9.

We can say that:

AB · X = A'B'

3 · X = 9

3X = 9

X = 9 ÷ 3

X = 3

Thus, figure B is 3x larger than figure A

scale factor = 3x larger

Answer:

x=3

Step-by-step explanation:

AB = 3 and A'B' '= 9.

hope this helps

Answer:

y = 2x^2 + 4x +6

Answer:

see below

Step-by-step explanation:

Identify the graph shown as linear or non linear.  - nonlinear since it is not a linear

Then estimate and interpret the intercepts of the graph,

y intercept -  ( 0,-6)  where it crosses the y axis

x intercepts ( -12,0)  and ( 12,0)

any symmetry,  symmetric across the y axis

where the function is positive, or above zero  (-∞, -12) and (12,∞)

negative, or below zero ( -12,12)

increasing,  growing ( 0, ∞)

and decreasing, getting smaller (-∞, 0)

the x-coordinate of any relative extrema,  the minimum is (0,-6)

and the behavior of the graph. As x goes to -∞ y goes to ∞  and s x goes to ∞ y goes to ∞

Answer:

You could solve this by taking the y value and adding it to the multiplied rate.

For example: For Jill's 6 year mark, the equation would be 11(6) + 15.

Hope this makes sense, don't hesitate to ask for clarification on a certain part of the answer.

Answer:

172.5 cups

Step-by-step explanation:

Q4 = 690

Q = [tex]\frac{690}{4}[/tex] = 172.5

∴ She weighed 172.5 cups

Answer:

The answer would be 60 miles.

Step-by-step explanation:

There are 60 second in a minute. If a cheetah runs 1 mile a second, the equation would be 1 mile X 60 seconds. 1x60=60.

Hope this helps!

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

Explanation:

Y is between X and Z (not necessarily at the midpoint). This means the three points are on the same line. Going from left to right we have X, Y and Z in that exact order.

Put another way, segment XZ is cut into smaller pieces XY and YZ.

The smaller pieces XY and YZ add back up to the largest segment XZ.

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

XY + YZ = XZ

( XY ) + ( YZ ) = XZ

( 7a ) + ( 5a ) = 6a+24 ..... substitution

7a+5a = 6a+24

12a = 6a+24

12a-6a = 24 ....... subtracting 6a from both sides

6a = 24

a = 24/6 ....... dividing both sides by 6

a = 4  is the first answer we're after

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

Use this value of 'a' to find the length of each segment

XY = 7a = 7*4 = 28

YZ = 5a = 5*4 = 20 is the second answer we want

XZ = 6a+24 = 6*4+24 = 48

Note how XY+YZ = 28+20 = 48 to match with XZ = 48 we got in the previous line above.

Answer:

La propiedad de la identidad de 1 dice que cualquier número multiplicado por 1 mantiene su identidad. En otras palabras, cualquier número multiplicado por 1 permanece igual. El número permanece igual porque multiplicar por 1 significa que tenemos 1 copia del número. Por ejemplo, 32x1=32.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The lines intersect at point L, so all angles have a vertex (middle letter) L so there is no angle TRL

Straight angle is a line with dot-vertex, so the straight angles are ∠RLS and ∠TLU.

∠TLS is less than 90° then it is acute angle (∠SLT is the same angle). ∠ULR is vertex angle to ∠TLS, so it's also acute angle.

Two angles adding to straight angle mean that they are both right angles or one is acute and the second is obtuse. ∠TLS is acute so ∠RLT is obtuse (they adding to ∠RLS) and ∠SLU is obtuse (they adding to ∠TLU). ∠ULS is the same angle as ∠SLU.

Answer:

Answer:

The next 2 items would be -80 and 160

The complete series is -5, 10, -20, 40, -80, 160, -320 and this can be determined by using the geometric progression.

Given :

-5, 10, -20, 40,...

The following steps can be used in order to determine the next item in the sequence:

Step 1 - The given sequence is in the geometric progression.

Step 2 - Write the given series.

-5, 10, -20, 40,...

Step 3 - The next term in the given sequence is:

= - 40 [tex]\times[/tex] 2

= - 80

Step 4 - After the above term the term obtained is:

= [tex]80\times 2[/tex]

= 160

Step 5 - After the above term the term obtained is:

= [tex]-160\times 2[/tex]

= -320

Answer:

500

Step-by-step explanation:

I will tell you what 460 is rounded to the nearest hundred and also show you what rules I used to get to the answer.

We did not necessarily round up or down, but to the hundred that is nearest to 460.

500

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Answer:

  a) 40 ft

  b) 7 inches

Step-by-step explanation:

A) Multiply the given scale factor by 8 to get 8 inches:

  1 in : 5 ft  ⇒  8 in : 40 ft

The real house is 40 ft high.

__

B) If you like, you can write the proportion ...

  dwg / (35 ft) = 1 in / (5 ft)

Multiplying by 35 ft gives ...

  dwg = (1 in)×(35 ft)/(5 ft) = 7 in

The length of the house in  the scale drawing is 7 inches.

Answer:

x = 5, RT = 18

Step-by-step explanation:

[tex]\triangle MNL \sim \triangle SRT... (given) \\

\therefore \frac{MN}{SR} = \frac{NL}{RT}.. (c.s.s.t)\\ \\

\therefore \frac{84}{24} = \frac{63}{3x+3}\\ \\

\therefore \frac{7}{2} = \frac{63}{3x+3}\\ \\

\therefore 3x+3 = \frac{63\times 2}{7}\\ \\

\therefore 3x + 3 = 9\times 2\\

\therefore 3x + 3 = 18\\

\therefore 3x = 18 - 3\\

\therefore 3x=15\\

\therefore x = \frac{15}{3}\\

\huge \red {\boxed {\therefore x = 5}} \\ \\

\because RT = 3x + 3\\

\therefore RT = 3\times 5+ 3\\

\therefore RT = 15+ 3\\
