slope of line perpendicular to AB will be -3

Answer: f(-1) = -12

Step-by-step explanation:

        To solve, we will substitute t for -1 into the function.

Given:

    h(t) = (t + 7)(t - 1)

Substitute:

    h(-1) = (-1 + 7)(-1 - 1)

Add and subtract:

    h(-1) = (6)(-2)

Multiply:

    f(-1) = -12

The given equations have in one, (1/5) is the coefficient of x, in the second equation, (1/5) is the coefficient of (x + 2), while both equations equals 6. Therefore, the value of x is different in both equations which do not represent the same situation.

The given equations are presented as follows;

[tex]\frac{1}{5} \cdot x + 2 = 6...(1)[/tex]

[tex] \frac{1}{5} \cdot (x + 2) = 6...(2)[/tex]

Solving each equation for x gives;

For equation (1), x = 5×(6 - 2) = 20

x = 20

For equation (2), we have;

x = 6 × 5 - 2 = 28

x = 28

Given that the value of x in the given equations are different, the situations are different.

A circle is a curve sketched out by a point moving in a plane. The radius and the diameter of the circle are 19.73 ft and 39.46 ft, respectively.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.

Given that circumference of the circle as 124 ft. Therefore, the radius and the diameter of the circle can be written as,

Circumference of circle = 2 × π × (Radius of the circle)

124 ft = 2 × π × (Radius of the circle)

(Radius of the circle) = 124 ft/ (2 × π)

The radius of the circle = 19.73 ft

Diameter of circle = 2 × (Radius of the circle)

                              = 2 × 19.73 ft

                              = 39.46 ft

Hence, the radius and the diameter of the circle are 19.73 ft and 39.46 ft, respectively.

The equation of the line in slope-intercept form passing through point (-3 , 1) and perpendicular to y = -(2/5)x - 4 is y = (5/2)x + 17/2

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula

y = mx + b

where m is the slope of the line

b is the y- intercept

If the line is perpendicular to y = -(2/5)x - 4, then their slopes are negative reciprocal of one another.

y = -(2/5)x - 4 : m = -2/5

m = 5/2

Substitute the values of the slope and the point to solve for the y-intercept, b.

y = mx + b

1 = 5/2(-3) + b

b = 17/2

Write the equation of the line by plugging in the value of the slope and y-intercept.

y = mx + b

-5/3 is the constant of variation where y varies directly with x.

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

A DIRECT VARIATION is a mathematical relationship between two variables that can be stated mathematically by an equation in which one variable equals a constant times the other.  y = kx

The right angle triangle ΔJ K L with legs JK and KL has been plotted below where the third side will be √(16b² + a²).

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

Given the triangle  ΔJ K L

Base = a  and Perpendicular = 4b

By Pythagoras theorem,

Hyp² = Base² + Perp²

Hyp² = a² + (4b)²

Step-by-step explanation:

The 20th term of the arithmetic sequence is 122.

nth term = a1 + d(n - 1) so here:

20th term = -30 + 8(20 - 1)

- 30 +  152

[tex]a_{20}[/tex] = 122.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

We are given the functions:

g ( x ) = x - 2

Now, we have a function y defined as:

y = f ( g ( x ) )

Now, we need to find the equation for y.

We know that:

f ( g ( x ) ) = 4⁽ ˣ⁻ ² ⁾

f ( g ( x ) ) = 4ˣ / 4²

f ( g ( x ) ) = 4ˣ / 16

Answer:

Step-by-step explanation:

Let's begin with adding all of the items Greg bought.

36.62 + 11.25 + 17.75 = 65.62

Let the money paid to the cashier be x.

Now, it's stated he paid 60 dollars to the cashier and that he also got $4.38 back from the cashier.

Then, it must be that x=65.62+4.38

x=70

The money he borrowed from friend = 70-60=10

Therefore, the money Greg borrowed from his friend to pay for all the items is $10.

Greg borrowed $1.24 from his friend.

A single unit's value may be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. We typically utilise this technique for math computations.

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Given:

Greg bought a blanket for $36.62,

a flag for $11.25,

and a glove for $17.75.

Total expense of the objects he brought

= 36.62+ 11.25 + 17.75

= $65.62

He paid $60 then

=65.62 - 60 = $5.62 remaining

Also, he got $4.38 in change from the cashier

= 5.62 - 4.38

= $1.24.

Hence, Greg borrowed $1.24 from his friend.
