x will represent the first unknow number
6x will represent the second number
the two numbers together will equal 21
6x + x = 21 combine like terms
7x =21 divide both sides by 7
x =3
Hope that helps.
brainliest is always appreciated.
To round 389,422 to the ten thousand, you need to go to the second number which is 8 and round it to the right. To the right of 8 is 9 so if a number is more than 5 you round 8 to 9. Then all the numbers after 8 turn into zeros
So... your answer is:
390,000

h(x) = 44

h(x) = x² - 5, h(-7) means x = -7
h(x) = (-7)² - 5
h(x) = 49 - 5
h(x) = 44
