Answer:

12/7 or 1 5/7

Step-by-step explanation:

to solve this equation you must first make both sides improper fractions

2 4/7 = 18/7

1 3/6 = 9/6

you can then simplify the fractions

18/7 cannot be simplified by 9/6 can

9/6 = 3/2

now we divide

$\frac{18}{7} / \frac{3}{2}$

when met with a division symbol when dealing with fractions you take the second fraction and flip it (reciprocal)

2/3

and then you multiply it

$\frac{18}{7} * \frac{2}{3}$

divide 18 and 3 by 3

now multiply

$\frac{6}{7} * \frac{2}{1} = \frac{12}{7}$

that is your answer

12/7 or 1 5/7

Two boats depart from a port located at (–8, 1) in a coordinate system measured in kilometers and travel in a positive x-directi

miss Akunina [59]

Answer:

$\left\{\begin{array}{l}y=-\dfrac{1}{9}x^2 +\dfrac{2}{9}x+\dfrac{89}{9}\\ \\y=\dfrac{1}{8}x^2 -7\end{array}\right.$

Step-by-step explanation:

1st boat:

Parabola equation:

$y=ax^2 +bx+c$

The x-coordinate of the vertex:

$x_v=-\dfrac{b}{2a}\Rightarrow -\dfrac{b}{2a}=1\\ \\b=-2a$

Equation:

$y=ax^2 -2ax+c$

The y-coordinate of the vertex:

$y_v=a\cdot 1^2-2a\cdot 1+c\Rightarrow a-2a+c=10\\ \\c-a=10$

Parabola passes through the point (-8,1), so

$1=a\cdot (-8)^2-2a\cdot (-8)+c\\ \\80a+c=1$

Solve:

$c=10+a\\ \\80a+10+a=1\\ \\81a=-9\\ \\a=-\dfrac{1}{9}\\ \\b=-2a=\dfrac{2}{9}\\ \\c=10-\dfrac{1}{9}=\dfrac{89}{9}$

Parabola equation:

$y=-\dfrac{1}{9}x^2 +\dfrac{2}{9}x+\dfrac{89}{9}$

2nd boat:

Parabola equation:

$y=ax^2 +bx+c$

The x-coordinate of the vertex:

$x_v=-\dfrac{b}{2a}\Rightarrow -\dfrac{b}{2a}=0\\ \\b=0$

Equation:

$y=ax^2+c$

The y-coordinate of the vertex:

$y_v=a\cdot 0^2+c\Rightarrow c=-7$

Parabola passes through the point (-8,1), so

$1=a\cdot (-8)^2-7\\ \\64a-7=1$

Solve:

$a=-\dfrac{1}{8}\\ \\b=0\\ \\c=-7$

Parabola equation:

$y=\dfrac{1}{8}x^2 -7$

System of two equations:

$\left\{\begin{array}{l}y=-\dfrac{1}{9}x^2 +\dfrac{2}{9}x+\dfrac{89}{9}\\ \\y=\dfrac{1}{8}x^2 -7\end{array}\right.$

A=1/4 and b=6. −8ab=

podryga [215]

Answer:

When $a=\frac{1}{4}$ and $b=6$ :

$-8ab=-12$

Step-by-step explanation:

-8ab can be seen as -8×a×b. Insert the given values:

$-8*\frac{1}{4} *6$

Simplify multiplication from left to right:

$-8*\frac{1}{4} \\\\\frac{-8}{1} *\frac{1}{4} =\frac{-8}{4} =-2$

Insert and solve:

$-2*6=-12$

Geometry. Very basic.

AveGali [126]

Answer:

A)10.25 cm ; B)5 square cm

Step-by-step explanation:

Formula:

p=(a+b+c) [p= perimeter ; a,b , and c are the side lengths.]

∴The perimeter of the triangle =(4+2.75+3.5) cm

=10.25 cm

Formula:

A = 1/2 . b .h [A=area ; b= base ; h= height]

∴The area of the triangle = (1/2 . 4 . 2.5) square cm [b=4 ; h=2.5]

=5 square cm
