An expression does not have an equal sign

Answer:

x = 30 + 5y / 2

Step-by-step explanation:

The slope of the line parallel to the given line is 2/5.

Slope of a line is the measure of the steepness and the direction of the line.

Given that, an equation of a line, 2x−5y = 30

Converting the equation in slope intercept form,

2x−5y = 30

5y = 2x - 30

y = 2/5x - 30

We know that the slope of two parallel lines are equal.

Hence, The slope of the line parallel to the given line is 2/5.

The equation that is equivalent to the slope formula is y₂ = m(x₂ - x₁) + y₁

An equation is an expression that shows the relationship between two or more numbers and variables.

The slope between two points A(x₁, y₁) and B(x₂, y₂) is:

Slope (m) = (y₂ - y₁) / (x₂ - x₁)

m = (y₂ - y₁) / (x₂ - x₁)

m(x₂ - x₁) = y₂ - y₁

y₂ = m(x₂ - x₁) + y₁

The missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.

We know that the sum of angles on a straight line is 180 degrees. Thus, we can say that;

∠1 + 118° = 180°

∠1  = 180 - 118

∠1 = 62°

We also know that sum of angles in a triangle is equal to 180°. Thus;

∠1 + ∠2  + 73 = 180

Plugging in the relevant value gives;

62 + ∠2  + 73 = 180

∠2 = 180 - 135

∠2 = 45°

∠2 + ∠3 = 180 - (∠1 + 49)

∠2 + ∠3 = 180 - (62 + 49)

45° + ∠3 = 69

∠3 = 22°

Thus, we conclude that the missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.

Step-by-step explanation:

what did your teacher do in class ? nothing ?

it is really not that complicated :

the slope of a line is the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.

it tells us how many units y changes when x changes by a certain number of units.

e.g. a slope of 2 = 2/1 means that when we increase x by 1, y increases by 2.

a positive slope means that the line goes up (seen while going from left to right).

a negative slope means that the line goes down.

therefore, a slope of 0 means a flat, horizontal line.

while for a vertical line the slope is the result of a division by 0 and is therefore undefined (some like to symbolize this by infinity).

parallel simply means to have the same slope. parallel lines imitate each other's behavior and attributes perfectly except for the absolute physical location.

perpendicular (at a 90° angle) slopes now simply turn x and y in the ratio upside-down and flip the overall sign of the slope.

e.g. the perpendicular slope of 2 = 2/1 is -1/2.

oh, and the slope of a function or curve that is not a line ?

then we go point by point, as the function does not have one slope for everything. and the slope of the function at a particular point is the slope of the tangent line at that point.

Answer:

Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles.

Step-by-step explanation:

If there is a pair of adjacent angles, then this pair is a linear pair if the sum of the (measures of the) two angles will be 180°. So, linear pair of angles always add up to 180°. For example, the linear pair of 30° is 150°, the linear pair of 70° is 110°, etc.

These two angles form a linear pair. We have found all four linear pairs of angles. The four linear pairs formed by the intersecting lines ←→QR Q R ↔ and ←→ST S T ↔ are ∠SOQ ∠ S O Q and ∠QOT ∠ Q O T , ∠QOT ∠ Q O T and ∠TOR ∠ T O R , ∠TOR ∠ T O R and ∠ROS ∠ R O S , and ∠ROS ∠ R O S and ∠SOQ ∠ S O Q .

The angle made by the vector is [tex]\theta[/tex] such that

[tex]\tan(\theta) = \dfrac{18.4\,\rm m}{-28.7\,\rm m} \approx -0.6411[/tex]

Before taking the inverse tangent of both sides, recall that [tex]\arctan[/tex] returns a number between -π/2 and π/2 radians, or -90° and +90°. The vector in the diagram clearly makes an angle between 90° and 180°, however, so we use the fact that tangent has a period of π rad / 180° to write

[tex]\theta \approx \arctan(-0.6411) + 180^\circ n[/tex]

where [tex]n\in\Bbb Z[/tex].

Now,

[tex]\arctan(-0.6411) \approx -0.5701 \,\mathrm{rad} \approx -32.6639^\circ[/tex]

Add 180° to this to recover the correct angle.

[tex]\theta = \arctan(-0.6411) + 180^\circ \approx \boxed{147.34^\circ}[/tex]

According to the graph,

Let y = [tex]{m_1}[/tex]x + [tex]b_1[/tex] [[tex]b_1[/tex] = 2]

when x = -2 , y = 0

-2[tex]m_1[/tex] + 2 = 0 [[tex]{m_1}[/tex] = 1]

If the inverse of f exists, it is represented by f⁻¹ and exists only if f is a bijective function.

If x = -3 then (f ⁰ g⁻¹)(x) is 23.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.

An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.

Let the two functions be f(x) = 3x² - 4 and g(x) = x - 2

(g⁻¹)(x) = 1 - 2

(g⁻¹)(x) = -1

substitute (g⁻¹)(x) value in (f ⁰ g⁻¹)(x)

(f ⁰ g⁻¹)(x) = (f ⁰ ) (-1)

then f(x) equation is 3 x² - 4 substitute -1 in x

f(-1) = 3(-1)² - 4

f(-1) = -1

Now when x = -3 the (f ⁰ g⁻¹)(x) value is

f(-3) = 3(-3)² - 4

f(-3) = 23

Therefore, the value of (f ⁰ g⁻¹)(x) for x = -3 is 23.

The direct variation equation can be used to find other combinations of x and y is y² = 4x³/27

Direct variation is variation in which one quantity increases as another quantity increases or decreases as anothe rquantity decreases.

Since we have that the square of y varies directly as the cube of x.

Writing this as a direct variation mathematically, we have

y² ∝ x³

So, the direct variation equation is

⇒ y² = kx³ where k = constant of proportionality

Now, given that when x = 4, y = 2.

Substituting the values of x and y into the equation, we have

y² = kx³

2² = k(3)³

4 = k(27)

k = 4/27

Substituting the value of k into the expression, we have

y² = kx³

y² = 4x³/27

Step-by-step explanation:

Based on the sample space, the probability of P(32) is 1/90

The probability of an event is the chance or the likelihood that the event would occur.

Note that the chance or the likelihood is represented as a numerical value

The sample space is given as

Space = two-digit numbers

There are 90 two-digit numbers

So, the sample size is

Size = 90

There is only one two-digit number with the value 32

So, we have

n(32) = 1

The probability of selecting 32 is

P(32) = n(32)/Size
