Let denote the two numbers with X and Y. n represent one number
Y=X + 3 1/3
The sum of the two numbers is: X+Y=X + X + 3 1/3
The triple sum is: 3(X + X + 3 1/3)
3(X + X + 3 1/3) = 133
3X + 3X + 10 = 133
6X + 10 = 133
6X = 123
X = 12 1/2 , Y= X+ 3 1/3 = 12 1/2 = 3 1/3 is the largest number
Answer:
<em>Axis of symmetry line is parallel to y- axis</em>
Equation of the parabola <em> ( x - ( -2 ))² = (y - 12 ) </em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given equation is y = x²+4 x+16
y = x²+2 (2 ) x + (2)² - (2)² + 16
y = ( x + 2 )² + 12
( x + 2 )² = y - 12
<em> ( x - ( -2 ))² = (y - 12 ) </em>
( x- h)² = 4 a ( y - k)
<em> Center (h ,k) = ( -2 , 12)</em>
<em> Here 4 a = 1 </em>
<em> a = 1/4</em>
<em>Focus S = ( h , K +a) = ( -2 , 12 + 0.25) = ( -2 , 12.25)</em>
<em>Axis of symmetry line is parallel to y- axis</em>
Answer:j
Step-by-step explanation:
If it’s closed it would be greater than -2 but since it’s open it’s equal or greater than
<span>This is a tricky question that Reina and Sam are multiplying (84)5 (73)9
and their work are
</span><span>(84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's
(84)5 (73)9 = 84⋅573⋅9 = 820727 Sam's
Actually they are doing or multiplying using exponents.
</span>
Reina’s work
(8⁴)₅(7³)⁹=8⁴⁺⁵+ 7³⁺⁹= 8⁹ 7¹²<span>
This is incorrect because she added exponents
instead of multiplying exponents
Sams work (8</span>⁴<span>)</span>⁵<span> (7</span>³<span>)</span>⁹<span>=8</span>⁴ˣ⁵<span> 7</span>³ˣ⁹<span>= 8</span>²⁰<span> 7</span>²⁷<span>
