Someone help again pls
xxMikexx [17]

Answer:

D

Step-by-step explanation:

First, compare the tens and ones places.

Bats 1 and 2 are each 27 point something ounces. 27 is less than 28 and 29, so we know the answer is either Bat 1 or 2.

Now let's look at the tenths place. Bat 1 is 27.1 oz, Bat 2 is 27.4. Since 1 is less than 4, we know that Bat 1 weighs the least!

"Benny decided to look at the price of new and used vans. Benny found a used van for $3000. Benny found that he paid 20% of the
shusha [124]

Answer:

$15000

Step-by-step explanation:

We have that the value of the truck is $ 3000 and that this payment is equivalent to 20% of the value of a new truck, therefore the value of the new truck would be:

% of value         value

      20               3000

     100                  x

x = 100 * 3000/20

x = 15000

therefore the value of the new truck is $ 15000

Rewrite the equation y-3=2(x+4) into slope form
soldi70 [24.7K]

Answer:

Step-by-step explanation:

So we have y-3=2(x+4)

So the first thing we want to do is distribute the 2 in front of the (x+4)

2(x+4) = 2x+8

Which means we have:

y-3=2x+8

Remember we need to get it into the form y=mx+b

As you can see here the 3 is preventing our equation from being in that form to we need to add it to both sides. This leaves us with:

y - 3 + 3 = 2x+8+3

Which gives: y = 2x+11

Therefore the slope form of this equation is y = 2x+11

Plot the vertex and the axis of symmetry of this function on the provided graph. f(x) = (x + 2)2 − 6
Nookie1986 [14]

Answer:

See attached image

Step-by-step explanation:

This equation for a parabola is given in vertex form, so it is very simple to extract the coordinates of its vertex, by using the opposite of the number that accompanies the variable "x" in the squared expression (opposite of 2) for the vertex's x-value, and the value of the constant (-6) for the vertex's y-value.

The vertex coordinates are therefore: (-2,-6)

The equation of the axis of symmetry of the parabola is a vertical line passing through the vertex. Since all vertical lines have the shape x = constant in our case, in  order to pass through (-2,-6) the vertical line is defined by the equation: x = -2.

See image attached to find the vertex drawn as a red point, and the axis of symmetry as an orange vertical line passing through it.
