I have mercy:

8x and 9x+5 (the angles) form a right angle so 8x+9x+5=90 which means x is 5 and plugging it back into the angles 8x we get 40 sinceBHR and angle 8x are vertical angles they are equal to each other and so it's equal to 40

P(5,6), -4x + 5y = 15 <br> into slope intercept form

Vaselesa [24]

Answer:

y = 4/5x - 3

Step-by-step explanation:

The slope-intercept form of a line is y = mx + b. We need to isolate the y.

(add 4x to 15)

-4x + 5y = 15

5y = 4x + 15

(divide by 5 from both sides)

y = 4/5x + 15/5

y = 4/5x + 3

James is solving the equation x^2+10x=50 by completing the square. What number must be added to both sides of the equation to co

Irina-Kira [14]

Let f (x) be a quadratic equation of the form:

$x^2+bx+c\\$

Where b and c are real numbers.

So a generic procedure for completing squares is:

1) identify b

In this case b = 10

2) divide b between 2 and then square it

$(\frac{b}{2})^ 2\\$

$(\frac{10}{2})^ 2=25\\$

3) Add and subtract $b ^ 2$ in the equation

$x ^2+10x + 25 - 25 = 50\\$

$x ^ 2 + 10x +25 = 75\\$

4) Rewrite the equation as follows

$(x+\frac{b}{2})^2=c\\$

$(x + 5) ^ 2 = 75\\$

The number that you must add to both sides of the equation is number $25 = (\frac{b}{2})^2$
