1 answer:

4 0

To solve this problem you must apply the proccedure shown below:

1. You have the following expressions shown in the problem above:

(<span>8m^2-6/n+3) + (9m^2-4/n+3)

2. As you can see, they have equal denominators, then you have:

(</span><span>8m^2-6+ 9m^2-4)/(n+3)
</span><span>
3. Therefore, when you sum, you have the following result:

(17m</span>²-10)/(n+3)
<span>
The answer is: </span> (17m²-10)/(n+3)<span>

</span>

At the beach, Pancho and his sister both built sandcastles and then measured their heights. Pancho's sandcastle was 3/5 of a foo

1/5 of a foot

Simply subtract the height of Pancho’s sandcastle (3/5 of a foot) minus the height of his sister’s sandcastle (2/5 of a foot) to find a difference of 1/5 of a foot, meaning Pancho’s sandcastle was 1/5 of a foot taller than his sister’s sandcastle.

find the equation of the line that is parallel to the line Y equals 3X -6 and passes through the points (1 -8). Write the equa

AlladinOne [14]

<h3>hello!</h3>

=====================================================

Parallel lines have the same slope.

So if the given line has a slope of 3, then the line parallel to it has the same slope (3)

Now, let's write the equation of the line in Point-Slope Form.

Remember, point-slope form looks like so:-

$\bigstar{\underline{\boxed{\pmb{y-y1=m(x-x1)}}}$

Where

y₁ is the y-coordinate of the point that the line passes through

m is the slope

x₁ is the x-coordinate of the point that the line passes through

In this case,

y₁ is equal to -8

m is equal to 3

x₁ is equal to 1

Plug in the values:

$\longrightarrow\sf{y-(-8)=3(x-1)}$

Simplify:

$\longrightarrow\sf{y+8=3(x-1)}$

and we're done!

=========================================================

Hope everything is clear; if you need any more explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

A recipe for 2 dozen cookies requires 3 cups of flour. The number of cookies baked varies directly with the amount of flour used

ollegr [7]

2 dozen = 24

24 cookies = 3 cups

24 x 2 = 48

48 cookies = 6 cups

24 x 3 = 72

72 cookies = 9

9 ~ 8

The table shows the relationship of how many pounds of cherries are needed to make a certain number of pies:

posledela

Answer:

C. A graph is drawn. The horizontal axis and vertical axis values are 0 to 70 in increments of 10. The horizontal axis label is Number of Pies, and the vertical axis label is Pounds of Cherries. Points are plotted on the ordered pairs 30, 20 and 45, 30 and 60, 40.

Step-by-step explanation:

If we take two of the original points from the data and put them in to two point form we get the following equation.

(6,4) and (12,8)

(y-4) = [(8-4)/(12-6)](x-6)

y = 2/3x

You have to start a the origin since we can only have enough ingredients to make pies and we can't start with partial pies. So move to y intercept up by 2.

Put the x values in for answer C and you'll return the y values.
