Answer:

Just to help you out in how to solve this just plug in every x of an equation -6, and in every y, -1. Plug these two number in every equation and see if it equal each other.Example:

y =4x +23

-1 = 4(-6) + 23

-1 = -24 + 23

-1 = -1

it shows that (-6,-1) is a solution to this equation

TRUE or FALSE: Every number raised to a negative exponent will have a value smaller than 1. Explain your reasoning.
Sveta_85 [38]

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Every number raised to a negative exponent will have a value smaller than 1.

  • This is False statement
<h3><u>Reason</u><u> </u><u>:</u><u>-</u></h3>
  • It will only be negative if the number is negative with an odd exponent.
  • what you're actually doing is dividing instead of multiplying.

Two consecutive even integers add up to 1594. what are the two numbers?
bezimeni [28]

Answer:

Hey there!

Consecutive integers mean that the numbers are next to each other.

Consecutive even integers mean that the numbers are separated by a number between them.

Thus, if x is the smaller number, x+2 can be used to write the larger number.

x+x+2=1594

2x+2=1594

2x=1592

x=796.

The two numbers are  796 and 798.

Let me know if this helps :)

Please help!! Maths question I don't understand!
djverab [1.8K]

Answer:

see explanation

Step-by-step explanation:

The statements tells us that w is inversely proportional to v and the equation relating them is

v = \frac{k}{w} ← k is the constant of proportion

To find k use the condition v = 9, w = 5, that is

9 = \frac{k}{5} ( multiply both sides by 5 )

45 = k

v = \frac{45}{w} ← equation of proportion

When w = 4 , then

v = \frac{45}{4} = 11.25
