Answer:

2 multiplyed  + 3.

Answer:30 degrees

Step-by-step explanation:There are a couple of ways to do this.

This is the straightforward, “follow-your-nose” way. Find a point on each line. (Say, (1,2) on the line with slope 2 and (-1,1) on the line with slope -1. Then the angle in the triangle formed by the origin (0,0) and these other two point is the desired angle. One can find the cosine of angle in the triangle using the Law of Cosines, since the lengths of all of the sides can be found directly from the distance formula and the coordinates of the points. Finally, use arccosine to get from the cosine of the angle to the angle itself.

There is also a “slick” way, which relies on remembering the subtraction formula for tangents. tan(u-v) = [tan(u) - tan(v)] / [tan(u) + tan(v)]. Consider u as the angle between the positive x-axis and the line with slope -1, and v as the angle between the positive x-axis and the line with slope 2. Then the requested angle is u-v. We know tan(u) = -1 and tan(v) = 2, so substituting into the subtraction formula for tangents allows us to find tan(u-v). Finally, use arctangent of that value to find u-v.

Answer:

f(x)=|x-6|

Step-by-step explanation:

Translation is a shift. Opposite how many units it moved. In with the x because that's side to side. If it was not with the x, it's up and down.

The transformation of a function may involve any change. The equation of g(x) is |x-6|.

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Vertical shift:

Stretching:

Given that the function f(x)=|x|, this function is needed to be translated 6 units to the right. Therefore, the new function can be written as,

g(x) = f(x-6)

      = |x - 6|

Hence, the equation of g(x) is |x-6|.

Answer:

6) 4 , 7) 35

Step-by-step explanation:

Answer:

x = 8 and x = 7

Step-by-step explanation:

(6)

Since the triangles are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{ST}{MN}[/tex] = [tex]\frac{RS}{LM}[/tex] , substitute values

[tex]\frac{x}{4}[/tex] = [tex]\frac{4}{2}[/tex] ( cross- multiply )

2x = 16 ( divide both sides by 2 )

x = 8

(7)

Since the prisms are similar then the ratio of corresponding sides are equal, that is

[tex]\frac{x}{35}[/tex] = [tex]\frac{2}{10}[/tex] ( cross- multiply )

10x = 70 ( divide both sides by 10 )

x = 7

Answer:

Prices of the two stocks A and B become​ same in 42 hours

Step-by-step explanation:

Let t denotes number of hours in which the prices of the two stocks A and B become​ same.

Price of stock A = $15.59

Increase in price per hour = $0.12 t

Price of stock B = $16.34

Decrease in price per hour = $0.11 (t - 3)

(since price of stock A starts increasing per hour after 9 A.M. and price of stock B starts decreasing per hour after 12 noon that is 3 hours after 9 A.M.)

To find number of hours in which the prices of the two stocks A and B become​ same, solve [tex]15.59+0.12t=16.34+0.11(t-3)[/tex]

[tex]15.59+0.12t=16.34+0.11(t-3)\\15.59+0.12t=16.34+0.11t-0.33\\0.12t-0.11t=16.34-0.33-15.59\\0.01t=0.42\\t=42[/tex]

So, prices of the two stocks A and B become​ same in 42 hours

Answer:

X = 20 degrees

Step-by-step explanation:

so we know that a triangle equals 180 degrees.

We already have 70 degrees so there are 110 degrees left.

Y is a right angle making it a 90 degree angle

110-90 equals 20 making x a 20 degree angle.

Answer:

4(2x+6)=32  x= 1

Step-by-step explanation:

multiply 4 to 2x and 6=   (8x+24)=32

then subtract 24 from 32 = 8

then divide 8 from both sides

8x/8=8/8

x=1

An equation is formed of two equal expressions. The unknown number is 1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the unknown number be represented by x.

The given statement can be written in the form of an equation as shown below.

         → 4(2x + 6) = 32

The given equation can be solved as shown below.

4(2x + 6) = 32

Open the parenthesis by multiplying 4 inside the parenthesis,

8x + 24 = 32

Subtract 24 on both sides of the equation,

8x + 24 - 24 = 32 - 24

8x = 8

Divide both sides of the equation by 8,

8x/ 8 = 8/8

x = 1

Hence, the unknown number is 1.

Answer:

IF YOU HAVE TO SOLVE FOR Y THEN TAKE X AS ANY NUMBER YOU WANT.

SUPPOSE X=2

PUT THE VALUE IN THE EQUATION THEN U WILL GET-

Y+2(2)=5

= Y+4=5

= Y=5-4

= Y=1

THIS IS JUST ONE EXAMPLE BUT THERE CAN BE INFINITIVE NUMBER OF ANSWERS FOR THIS QUESTION.

I WILL SHOW U ONE MORE EXAMPLE.

IF X=1

THEN THE EQUATION WILL BE-

Y+2(1)=5

Y+2=5

Y=5-2

Y=3

SO HERE WE GOT Y=1&3

AND ALSO Y CAN HAVE INFINITE SOLUTIONS (THIS IS ON THE BASIS OF THE PROPERTY OF LINEAR EQUATION, I.E., A LINEAR EQUATION CAN HAVE INFINITIVE SOLUTIONS)

Answer:

C. 15 units

Step-by-step explanation:

PM = 7 units

p..............M..........N............Q

   7 unit                     4 unit

NQ = 4 units

Given that

N is midpoint of MQ

it means N divides MQ into two equal parts

thus

MN = NQ = 4 units

now

we have to find length of PQ

p..............M..........N............Q

   7 unit     4 units     4 unit

PQ = PM + MN + NQ

PQ = 7 units + 4 units + 4 units = 15 units

thus, correct answer is option c 15 units
