Answer:

55°

Step-by-Step Explanation:

Supplementary Angles means it adds up to 180°.

You can find the measure of the missing angle by doing 180°-125°=55°.

The square of a number is 12 less then 7 times the number. 2hat is the number

Salsk061 [2.6K]

Hello.

The are answer is 4 or 3


3^2 = 7(3) - 12
9 = 21 - 12
9 = 9

4^2 = 7(4) - 12
16 = 28 - 12
16 = 16

Graph the linear inequality. 3x-y<6

Sphinxa [80]

Answer:

Step-by-step explanation:

3 x - y < 6

dividing whole equation by 6 equation comes out to be

$\frac{3x}{6}-\frac{y}{6}$

$\frac{x}{2}+\frac{y}{-6}$

from the above equation we can clearly see that the x and y co-ordinate

x co-ordinate will be (2,0) where y coordinate will be(0,-6)

and the plot is given in the attachment given below.

where as the shaded portion gives the desired region.

Please solve y=x^2-6x-5 by factoring and by using the quadratic formula with work attached

Lynna [10]

Factoring:

This equation cannot be factored because its roots are irrational (as shown by solving with the quadratic formula). Also, to factor a quadratic equation, you need to find a pair of numbers whose product is equal to the c term (-5) and whose sum is equal to the b term (-6). There is no pair of numbers which satisfies this, further showing that the equation cannot be factored.

Quadratic Formula:

The quadratic formula is x= $\frac{-b ± \sqrt{b^{2}-4ac } }{2a}$ .

First, you need to find the a, b and c terms of your equation. They are 1, -6, and -5 respectively.

Now, you must plug in to the equation and solve for x. You must do so twice, once with a plus sign in the numerator and once with a minus.

$\frac{6 ± \sqrt{(-6)^{2}-4(1)(-5) } }{2(1)} \\\frac{6 ± \sqrt{36+20} }{2} \\\frac{6 ± \sqrt{56} }{2} \\\ \frac{6 ± 2\sqrt{14} }{2} \\3+\sqrt{14} \\3-\sqrt{14}$

The answers are 3+√14 and 3-√14.

Hope this helps!!
