2x + 7 = 19
X=?
Which one is the answer

Answer:

The value of g(f(3)) = 2

Step-by-step explanation:

We are given:

[tex]f(x)=2x[/tex]

[tex]g(x) = x-4[/tex]

And we need to find g(f(3))

First we need to find g(f(x))

by putting the value of f(x) into g(x) i.e put x = 2x

[tex]g(x)=x-4\\g(f(x))=2x-4[/tex]

Now, we need to find g(f(3)) by putting x = 3 in g(f(x))

[tex]g(f(x))=2x-4\\Put\: x=3\\g(f(3))=2(3)-4\\g(f(3))=6-4\\g(f(3))=2[/tex]

So, the value of g(f(3)) = 2

Answer:

A circle is a shape.

Step-by-step explanation:

In geometry circles are known for you to solve the radius wit the formula      A= π r^2

A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

Answer:

5.55

Step-by-step explanation:

With reference angle 48°

perpendicular (p) = x

base (b) = 5

Now

tan 48° = p / b

1.11 = x / 5

x = 1.11 * 5

x = 5.55

Answer:

Option D is correct .

Step by step explanation:

A function is given to us and we need to find its inverse . The function is g(x) = -2x⁵ - 2.

So for finding its inverse , exachange x with y .

⇒ g(x) = -2x⁵ - 2 .

Let g(x) = y ,

⇒ y = -2x⁵ - 2 .

Replace x with y ,

⇒ x = -2y⁵ - 2

⇒ x + 2 = -2y⁵

⇒ y⁵ = x+2 / -2

⇒ y⁵ = (-1) ( x + 2) / (-1)(-2)

⇒ y⁵ = -x - 2/ 2

⇒ y = ⁵√ [ ( -x -2)/2 ]

Hence the inverse of the function is ,

[tex]\boxed{\red{\bf f^{-1}(x)=\sqrt[5]{\dfrac{-x-2}{2}}}}[/tex]

Answer:

A,C,E

Step-by-step explanation:

Answer:

B. n ≥ -24.

D. The circle is closed.

E. The arrow points right.

Step-by-step explanation:

Step 1: Multiply both sides by -3/2, the reciprocal of -2/3. Since -2/3 is negative, the inequality direction changes.

(-2/3 * -3/2)n ≤ 16(-3/2)

n ≥ 16(-3/2)

Step 2: Express 16(-3/2) as a single fraction.

n ≥ 16(-3)/2

Step 3: Multiply 16 by -3 to get -48.

n ≥ -48/2

Final Step: Divide -48 by 2 to get -24.

n ≥ -24 is the final answer.

With inequalities that have this (≥), the circle should be closed (D) and the arrow goes right (E).

Step-by-step explanation:

Answer:

B. y = 11x - 7 passes through the points (2 , 15) and (3 , 26)

Step-by-step explanation:

Answer:

122°

Step-by-step explanation:

10a + 2° + 5a - 2° = 180° [ being linear pair ]

15a = 180°

a = 180° / 15

a =12°

Now

<XYQ = 10a + 2° = 10 * 12° + 2° = 120° + 2° = 122°

Hope it will help :)

Answer:

∠VUW

Step-by-step explanation:

A triangle is a three sided polygon with three angles. Types of triangles are obtuse, scalene, isosceles, equilateral and so on.

In triangle VUW, since VU = WU, hence it is an isosceles triangle. In an isosceles triangle, two sides of the triangle are equal.

The size of an angle depends on its opposite side, the higher the opposite side the higher the angle. Since In triangle VUW, VU = 9, WU = 9, VW = 5. Since VW is the smallest side, the angle opposite to VW is the smallest angle.

Hence the smallest angle = ∠VUW

Answer:

[tex]P(F) = 0.515[/tex]

[tex]P(M) = 0.485[/tex]

Step-by-step explanation:

Given

[tex]Female = 51.5\%[/tex]

Solving (a): Probability of running into a female

To do this, we simply convert the given proportion to decimal

[tex]P(F) = 51.5\%[/tex]

Convert to fraction

[tex]P(F) = \frac{51.5}{100}[/tex]

[tex]P(F) = 0.515[/tex]

Solving (b): Probability of running into a male

Represent this with [tex]P(M)[/tex]

To solve this, we apply the concept of probability complement which states that:

[tex]p + q = 1[/tex]

In this case:

[tex]P(F) + P(M) = 1[/tex]

Substitute 0.515 for P(F)

[tex]0.515 + P(M) = 1[/tex]

Subtract 0.515 from both sides

[tex]0.515-0.515 + P(M) = 1 - 0.515[/tex]

[tex]P(M) = 1 - 0.515[/tex]

[tex]P(M) = 0.485[/tex]

Answer:

50 degrees

Step-by-step explanation:

Since the two lines are parallel, we know that the other angle above angle 1 is also 130, because corresponding angles are congruent. Next, since we know that it sits on a line, we know that angle 1 and 130 make a linear pair, or add up to 180 degrees. 180-130= angle 1. So angle 1 is 50 degrees. Sorry if the explanation is a bit funky.

Answer:

Step-by-step explanation:

think of this as a system of equations where the colors just represent a variable like x or y

I'll just arbitrarily set colors to some variable letter so we have

purple = x

green =y

blue =z

red = a

yellow = b

so we can now rewrite the 4 known equations of the system :)

Eq. 1)  x+y = 13

Eq. 2) 2y+2z=18

Eq. 3) 2x+3y=31

Eq. 4) z + 4a = 12

Eq. 5) a * y = b

so solve the 1st eq for y   =>  y =13-x    then plug that into the 3rd eq and slove for x =>  2x + 3(13-x) =31

2x + 39 -3x = 31

2x-3x = 31 - 39

-x = -8

x=8

plug 8 into Eq. 1 for x and solve for y

8+y = 13

y=5

plug y into Eq 1 and solve for z

2(5) +2z = 18

10 +2z = 18

2z = 8

z = 4

plug z into E1 4 and solve for a

4 + 4a = 12

4a = 8

a = 2

plug a and y into Eq 5 and solve b

2 * 5 = b

10=b

go to the drawing and plug in each of the color values that we put as variable letters above and get an A+ on your homework..  :)
