The equation x + y = z relates the whole numbers x, y, and z. How does z compare to x? Y is z less than x. Y is z more than x. X

rewona [7]

Answer:

x is y less than z

Step-by-step explanation:

The given equation is x + y = z

This equation relates the whole numbers x, y, and z.

This equation can be rearranged to make x the subject of the formula or to make y the subject of the formula. When this is done, the relationship between the terms or numbers would be clearly expressed.

Making y the subject of the formula, it becomes

y = z-x (this shows that z is greater than y by x)

Making x the subject of the formula, it becomes

x = z-y (this shows that z is greater than x by y)

Looking at the options given, the correct comparisons between z and x is

x is y less than z

A recipe of pasta makes enough for eight servings. How many servings can be made using 4/8 of each ingredient in the recipe?

marta [7]

4/8 is the same as 1/2, so half. If you only have 4/8, then half of eight is 4. 4 servings.

What are the first four terms in the sequence generated by the formula? an=n^2+2n+1

kotykmax [81]

Given the formula:

$a_n=n^2+2n+1$

First term:

$a_1=1^2+2(1)+1=1+2+1=4$

Second term:

$a_2=2^2+2(2)+1=4+4+1=9$

Third term:

$a_3=3^2+2(3)+1=9+6+1=16$

Fourth term:

$a_4=4^2+2(4)+1=16+8+1=25$

Answer: the first four terms are: 4, 9, 16 and 25

What are the coordinates of the midpoint of the line segment with endpoints 2,5 and 4,-7

Phoenix [80]

<h3>Answer: (3, -1)</h3>

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

Explanation:

The midpoint formula is $(x_m, y_m) = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)$

This basically says to add the corresponding coordinates and divide by 2.

The given points (2,5) and (4,-7) have x coordinates of 2 and 4. They add to 2+4 = 6, and then that result cuts in half to 6/2 = 3. The x coordinate of the midpoint is 3.

The y coordinate of the midpoint is y = -1 since adding the y coordinates of the given points leads to 5+(-7) = -2 which cuts in half to -1.

So overall the midpoint is located at (3, -1)
