A rational number<span> is any </span>number that can be expressed as the quotient or fraction. It is also a number that does not repeat and/or go on forever (ex. pi or <span>3.1415926535</span><span>)
Soo, the rational number is
the √49
√49 = 7 7 is a rational number, also a whole number as well, how bout that.</span>
Answer: -2049. Explanation: Use PEMDAS to solve the equation (parenthesis, exponents, multiplication/division, and addition/subtraction). First multiply the numbers that are being multiplied. You should get 44 + 27 - 2100 - 20. Now start from the beginning, and either add or subtract. The answer is -2049.
Answer:
5x - y + 38 = 0
Step-by-step explanation:
solution:
slope(m) = 5
(x1 , y1) = (-8 , -2)
we know that,
(y - y1) = m(x -x1)
or, (y - -2) = 5(x - -8)
or, y+2 = 5(x + 8)
or, y+2 = 5x +40
or, 5x - y + 38 = 0 is the required equation
Answer:
1. x=6
2. x=9
Step-by-step explanation:
1.

2.

<u>Written Explanation: </u>
1.
-2x(3x+9)=-54
-6x-`8=54 (Distributive property)
Add 18 to both sides
-6x=-36
Divide both sides by -6 (negative divided by a negative equals a positive)
x=6
2.
2(3x+4)-3x=35
6x+8-3x=35 (distributive property)
3x+8=35 (combine Iike terms and then subtract them 6x-3x=3x)
Subtract 8 from both sides
3x=27
Divide both sides by 3
x=9
