Answer:

You have to use the subsitution method

Step-by-step explanation:

so it's telling you what the y value is an you have to subsitute 6x-b where the y is.

so the new eqaution would be -3x+1/2(6x-b)=-3

-3x+3x-b=-3

-b=-3

b=3

the b is the in y=x+b

Answer:

x = 34

Step-by-step explanation:

The 3 labeled angles create a straight line, so that means they will add up to 180°.

(x + 12) + 100 + x = 180

2x + 112 = 180

Subtract 112 from both sides.

2x = 68

Divide both sides by 2.

x = 34

The value of x in the figure is, 34.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

We know that;

A straight line make an angle 180°.

Hence, By the figure we get;

⇒ (x + 12)° + 100° + x° = 180°

⇒ x + 12 + 100 + x = 180

⇒ 2x + 112 = 180

⇒ 2x = 180 - 112

⇒ 2x = 68

⇒ x = 34

Answer:

Step-by-step explanation:

4x - 2y = -2   ------------------(I)

6x + 3y = 27 ------------------(II)

Multiply (I) by 3 & multiply (II) by 2

(I)*3           12x - 6y = -6

(II)*2          12x + 6y = 54  { Now add &  y will be eliminated}

               24x          = 48

 x = 48/24

x = 2

Plugin the value of x in equation (I)

4*2 - 2y = - 2

8 - 2y = -2          {subtract 8 from both side}

-2y = -2 - 8

-2y = -10   {Divide both sides by -2}

y = -10/-2

y = 5

The required functions are obtained as f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.

The inverse of a function y = f(x) is defined as a function having range as the domain of the function f(x) and domain as the range. Mathematically it can be written as f⁻¹(y) = x which implies that f⁻¹(f(x)) = x.

The given problem can be solved as follows,

(a) f⁻¹(x) = 5x

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = 5f(x)

=> x = 5f(x)

=> f(x) = x/5

(b) f⁻¹(x) = x³/2

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = f(x)³/2

=> x = f(x)³/2

=> f(x) = ∛(2x)

(c) f⁻¹(x) = x + 10

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = f(x) + 10

=> x = f(x) + 10

=> f(x) = x - 10

(d)  f⁻¹(x) = 3( x + 17)/2

Substitute x = f(x) to obtain,

f⁻¹(f(x)) = 3( f(x) + 17)/2

=> 2x = 3( f(x) + 17)

=> 2x/3 = f(x) + 17

=> f(x) = 2x/3 - 17

Hence, the functions for the given inverse functions are  f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.

Answer:

Step-by-step explanation:

Let x be the random variable. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 474

σ = 32

x = 514

The probability of being below 514 is expressed as P(x < 514)

For x = 514,

z = (514 - 474)/32 = 1.25

Looking at the normal distribution table, the probability value corresponding to area below the z score is 0.89

Therefore,

P(x < 514) = 0.89

Option A.  yes by ASA is correct.

Triangles F H G and K J G share common point G. The lengths of sides H G and G J are congruent. Angles F H G and K J G are right angles.

Similar triangles, are those triangles which have similar properties,i.e. angles and proportionality of sides.

Since we have one angle FHG and angle KJG and one side from both triangle HG = GJ equal
so the angle opposite to equal side must be equal. i.e.
Angle HFG = Angle JKG
hence , triangle is congruent by ASA

At an ice cream shop, the profit, P(c), is modeled by the function ;

P(c) = 0.87c. An appropriate domain for this function is an integer [tex]\geq[/tex] 0.

A function is defined as a relation between the set of inputs having exactly one output each.

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

Answer: 720 I think

Step-by-step explanation: Because if there are 720 cubic units, you can only fit 720.

There will be 720 cubes of side 1 unit that fill the prism if they were packed without any gaps or overlaps.

Volume is defined as the space occupied within the boundaries of any three-dimensional solid.

Given that, a rectangular prism has a volume of 720 cubic units, we need to find that, how many unit cubes would fill the volume with the solid if they were packed without any gaps or overlaps,

So, to find the same, we will divide the volume of the prism by the cube.

Volume of the cube = side³ = 1³ = 1

Therefore, number of cubes to be fitted = 720 / 1 = 720

Hence, there will be 720 cubes of side 1 unit that fill the prism if they were packed without any gaps or overlaps.

Step-by-step explanation:

Please find attached to this question, the required diagram.

From the question, we are told we have a spherical mold.

We would find the volume of a spherical mold using the formula for the volume of a sphere.

The volume of a sphere is calculated as : 4/3πr³

From the attached diagram, we are given the Diameter do the spherical mold as: 22mm

Radius of the spherical mold = Diameter ÷ 2 = 22mm÷ 2 = 11mm

The volume of the spherical mold = 4/3 × π × 11³

= 1774.6666667π mm³

Approximately and leaving it in terms of pi (π)= 1774.67π mm³
