Solve the system using substitution 4x+3y=23 x-5=0

Mathematics
1 answer:
iragen [17]3 years ago
3 0

Answer:

y=1, x=5

Step-by-step explanation:

Since x-5=0 is given already, give the x a value and switch the 5 to the other side x-5=0 ----> x=5

Now we have a value for x, so plug x into the original equation,

4(5)+3y=23,

20+3y=23

Subtract both sides by 20

20-20+3y=23-20

3y=3

dvide both sides by 3

y=1

use the value for x we got earlier

y=1, x=5

16. Which set of decimals is in order from
prisoha [69]

The set of decimals which is in order form is

0.007, 0.069, 0.69,  0.7

Step-by-step explanation:

In the question we have to check for the order pair which is adequately arranged in the form “Least to greatest”

  • 0.64, 0.604, 0.064, 0.06- This set is not arranged in the the above mentioned order since 0.64 is the greatest of all the numbers.  
  • 0.603, 0.75, 0.08, 0.098- The set is not in the order form since 0.08 is small than 0.75 but is placed later than 0.75.  
  • 0.5, 0.064, 0.701, 0.901- This is also in the ordered form since 0.064 is smaller than 0.5 and is placed later than 0.5
  • 0.007, 0.069, 0.69, 0.7- This pair is in the ordered pair. All the numbers are arranged in the above mentioned order. 0.007 is the smallest and 0.7 is the largest

Convert <br> [−1,∞) to inequality notation use the variable x.
Trava [24]

Answer:

-1\leq x

Step-by-step explanation:

We want to convert the interval [-1, ∞) to inequality notation using <em>x</em> as the variable.

The interval [-1, ∞) reads: "All real numbers between -1 and positive infinity."

In other words, it is all numbers greater than or equal to -1 and less than positive infinity.

Therefore:

-1\leq x

Note that we do not use "or equal to" for the infinity as we can never really "equal" infinity.
