This is the case because quadratum is the Latin word for square, and since the area of a square of side length x is given by x2, a polynomial equation having exponent two is known as a quadratic ("square-like") equation

Does the point (2, 9) satisfy the inequality y ≤ 3 x + 1 ?

Naily [24]

A point is written using the form (X,Y), so the first number is the X and the second number is the Y.

Replace x and Y in the given equation with the given point:

y ≤ 3x+1

9 ≤ 3(2) +1

9 ≤ 6 +1

9 ≤ 7

9 is not less than or equal to 7, so the point (2,9) does not satisfy the inequality.

If y varies directly as x and y-21 when x is 7, find x when y = -5.

klasskru [66]

Step-by-step explanation:

Since, y varies directly as x:

$\therefore \: y = kx..(1) \\ (k = constant \: of \: proportionality) \\ at \: y = 21 \: and \: x = 7 \\ 21 = k \times 7 \\ k = \frac{21}{7} = 3 \\ plugging \: k = 3 \: in \: equation \: (1) \\ y = 3x..(2) \\ plugging \: \: y = - 5 \: in \: (2)\\ - 5 = 3x \\ x = \frac{ - 5}{3} \\ \: \: \: \: \: \: \huge \red{ \boxed{x = - \frac{5}{3} }}$
