Answer:
Rational number- a number that can be expressed in the form of p/q where q is not equal to 0 (zero).
The <u>square root</u> of <u>38</u> is <u>6.1644140030. </u>
<u />
Square root of 38 is not a <u>rational number</u> because it cannot be expressed as a <u>fraction </u>and thus, is an<u> irrational number.</u>
Hope this helps
and have a nice day ahead

Answer:
Slope: -3
y-intercept: (0, 8)
Step-by-step explanation:
The equation y = mx + b is used for all linear equations. In this equation, m = slope and b = y-intercept.
In order to find these two variables, you must put the equation given into the y = mx + b format.
y = 8 - 3x becomes y = -3x + 8
That means that m = -3 = slope and b = 8 = y-intercept.
I hope this helps!
Answer:
The online store will save you the most
Step-by-step explanation:
-2 = - x + x^2 -4 => x^2 - x - 4 + 2 = 0
x^2 - x - 2 = 0
a is the coefficient of x^2 => a = 1
b is the coefficient of x => b = - 1
c is the constant term => c = - 2
quadratic equation: [- b +/- √(b^2 - 4ac) ] / 2a =
= { 1 +/- √[ (-1)^2 - 4(1)(-2)] } / (2(1) = { 1 +/- √ (1 + 8) } / 2 = {1 +/- √9} / 2 =
= { 1 +/- 3} / 2
