F(6) means f times 6 so f6

So f(6) means that x is 6. All you’re going to do is plug in 6 for x.

f(6) = 21(6) • 12

f(6) = 126 • 12

f(6) = 1,512

I hoped this helped you understand!!

Find the coordinates of the midpoint M of the segment with the given endpoints. Then find the distance between the two points. R
MrRa [10]
Question 1. Midpoint

Answer: M(-2,4)

Explanation:

1) The coordinates of the midpoint, M (x,y) between two points (x₁,y₁) and (x₂, y₂) are:

x = (x₁ + x₂) / 2 and y = (y₁ + y₂) / 2

2) Replacing the coordinates of the given points P (-4, 1) and Q (0,7) you get:

x = (- 4 + 0) / 2 = - 2, and
y = (1 + 7) / 2 = 4

So, the answer is M (-2,4)


Question 2: The distance between the two midpoints is:

Answer: 7.21


Explanation:

1) Use the formula of distance, which is an application of Pythagora's theorem:

d² = (x₂ - x₁)² + (y₂ - y₁)²

2) Substitute values:

d² = (0 - (-4))² + (7 - 1)² = 4² + 6² = 16 + 36 = 52 ⇒ d = √52 ≈ 7.21

The perimeter of an equilateral triangle is 83 inches. If the length of each side is (2x -3), find the value of x.
Minchanka [31]

Answer:

x = 15 \frac{1}{3}

Step-by-step explanation:

Equilateral triangles have 3 equal sides.

Thus, perimeter of triangle

= 3(2x -3)

= 3(2x) +3(-3) <em>(</em><em>expand</em><em>)</em>

= (6x -9) inches

Given that the perimeter is 83 inches,

6x -9= 83

6x= 83 +9 <em>(</em><em>+</em><em>9</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

6x= 92

x = 15 \frac{1}{3}

Rashid left a $15 tip for a $75 restaurant bill. What percent tip did he leave?
Nat2105 [25]

Answer:

20%

Step-by-step explanation:

15 over 75 equals x over 100. 15 × 100 over 75 equals 75x over 75. 1500 ÷ 75 is 20. (Hard to explain like this. sorry if you couldn't understand)

It is possible to get 2 solutions when the system of equations is: (check all that apply)
SVETLANKA909090 [29]

Answer:

A system of the equation of a circle and a linear equation

A system of the equation of a parabola and a linear equation

Step-by-step explanation:

Let us verify our answer

A system of the equation of a circle and a linear equation

Let an equation of a circle as x^2+ y^2 = 1 ..........(1)

Let a liner equation Y = x ............(2)

substitute (2) in (1)

x^2 + x^2 = 1\\2x^2 = 1\\

x^2 = \frac{1}{\sqrt{2} } \\x = +\frac{1}{\sqrt{2} } , -\frac{1}{\sqrt{2} }  so Y = +\frac{1}{\sqrt{2} } , -\frac{1}{\sqrt{2} }

so the two solution are ( (\frac{1}{\sqrt{2} } ,\frac{1}{\sqrt{2} }) (-\frac{1}{\sqrt{2} }, -\frac{1}{\sqrt{2} })

A system of the equation of a parabola and a linear equation

Let equation of Parabola be y^2 = x

and linear equation y = x

substitute

x^2 = x\\x^2 - x= 0\\x(x-1) = \\x = 0 , 1

Y = 0,1

so the two solutions will be (0,0) and (1,1)
