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

1.Write an example of how the product of two different irrational numbers can be a rational number.
Digiron [165]

Answer:

1 "The product of two irrational numbers is SOMETIMES irrational." The product of two irrational numbers, in some cases, will be irrational. However, it is possible that some irrational numbers may multiply to form a rational product.

2 The quotient has widespread use throughout mathematics, and is commonly referred to as a fraction or a ratio. For example, when dividing twenty (the dividend) by three (the divisor), the quotient is six and two thirds. In this sense, a quotient is the ratio of a dividend to its divisor.

3 The sum of two irrational numbers, in some cases, will be irrational. However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational. "The product of two irrational numbers is SOMETIMES irrational."

what equation would represent the same linear relationship for the points (40,80) (80,115) (120,140) (160,165)
tiny-mole [99]
You can use the formula y1-y2=m(x1-x2)

to find m, you just do (y2-y1)/(x2-x1) so....

(115-80)/(80-40)= 35/40= 7/8

then plug it into the point slope equation:

y-115=7/8(x-80)

y-115=7/8x-70
y= 7/8 x + 45
