Answer:

16y

Step-by-step explanation:

Firstly you would times the numbers, then you have a look at the algebraic notation and then add "y" at the end of the numbers

so it would be 2 x 8 = 16 x Y = 16y

Y doesnt have a value of a number it will stay a letter

You could say the value of y is 1 so 16 x 1 = 16 but it would be 16y

Please mark brainliest!

Hope this helped!!

a) First, multiply the numbers 8 and 2, and we get 16.

Now, we have to multiply 16 and the algebraic notation “y”, we get the result of 16y.

<h3><u>Whenever you multiply the number(s) with algebraic notations, you need to multiply the number(s) and write the algebraic notation at the end.</u></h3>

<u></u>

b) Multiply the number 8 and the algebraic notation “y”, and we get the result 8y.

Hey there!

-4.36 + 1.2 [2.8 +(-3.51)]

= -4.36 + 1.2(2.8 - 3.51)

= 4.36 1.2(-0.71)

= -4.36 - 0.852

= -5.212

Therefore, your answer is: -5.212

Good luck on your assignment and enjoy your day!

Point M is the midpoint of AB. The coordinates of point A are (−7, 1) and the coordinates of M are (−2, 2). What are the coordin

notka56 [123]

Answer:

$\huge{\boxed{\sf{ ( 3 , 3 ) }}}$

Step-by-step explanation:

Co-ordinates of point A = ( -7 , 1 )

Co-ordinates of point M = ( -2 , 2 )

Let the co-ordinates of point B be ( x , y )

A ( -7 , 1 ) $\longrightarrow$ ( x1 , y1 )

B ( x , y ) $\longrightarrow$ ( x2 , y2 )

Now,

Midpoint = $(\frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

⇒ $( -2 , 2 ) = ( \frac{-7 + x}{2} , \frac{1 + y}{2} )$

Finding the value of x :

⇒ $-2 = \frac{-7 + x}{2}$

Do cross multiplication

⇒ $-4 = -7 + x$

⇒ $-7 + x = -4$

⇒ $x = -4 + 7$

⇒ $x = 3$

Now, finding the value of y

⇒ $2 = \frac{1+y}{2}$

Do cross multiplication

⇒ $4 = 1+y$

⇒ $1+y = 4$

⇒ $y = 4 - 1$

⇒ $y = 3$

Hence, The co-ordinates of point B = ( 3 , 3 )

Hope I helped!

Best regards!

Answer:

<h2>B. The amount of fuel used was lowest at speeds around 60km/h.</h2>

Step-by-step explanation:

The decreasing part is from (20,13) to (60,6), which gives an average rate of

$r=\frac{6-13}{60-20}=-\frac{7}{40}=-0.175$

Then, we have an increasing part from (60,6) to (120,10), which gives an average rate of

$r=\frac{10-6}{120-60}=\frac{4}{60}=0.067$

Basically, at 60 km/h the fuel used was 6 liters per 100 kilometers. Notice that the other velocities make the car to use more liters per kilometers.

Therefore, the amount of fuel used was lowest at speeds around 60 km/h.
