How to solve : y = 6x-5 y = -x+9 by substitution method???

Mathematics

Answer:

(2,7)

Step-by-step explanation:

y = 6x - 5

y = -x + 9

ok...so y = 6x - 5...so sub 6x - 5 in for y back in the 2nd equation

6x - 5 = -x + 9....add x to both sides

6x + x - 5 = 9....add 9 to both sides

6x + x = 9 + 5 ....combine like terms

7x = 14....divide both sides by 7

x = 14/7...reduce

x = 2

now sub 2 in for x in either of ur original equations and find y

y = 6x - 5

y = 6(2) - 5

y = 12 - 5

y = 7

and u can check ur answer by subbing ur answer back into either of both of the original equations

y = -x + 9

7 = -2 + 9

7 = 7 (correct)...so it checks out

ur solution is : x = 2 and y = 7 or (2,7)

A number has the same digit in its hundreds place and its hundredths place.
Yuki888 [10]

Answer:

One is 2 0's before the decimal point (100) and the other is 2 decimal places AFTER the decimal point (0.01)

Essentially, the question is asking us how many times do we multiply 0.01 to get 100? This will be how many times greater 100 is compared to 0.01

Lets move the decimal point  4 times to the right:

0.01

00.1

1.0

10.0

100.0

STALIN [3.7K]

Answer:

-21 = 6t

Step-by-step explanation:

3t - 7 = 5t

Subtract 3t from each side

3t-7-3t = 5t-3t

-7 = 2t

Multiply each side by 3 to get 6t

-7*3 = 2t*3

-21 = 6t

Answer:

This works because the metric system is based on powers of 10.

Step-by-step explanation:

since it's based on 10 it allows you to move the decimal to the left or right because each time you move it it goes up 10 or down ten depending on which way you move it. Each time you move a decimal it goes 10 either way.
