Answer:
<em>- 4</em>
Step-by-step explanation:
( 3 - r ) / ( 1 + 5) = 7/6
=
⇒ 3 - r = 7 ⇒ r = <em>- 4</em>
Hello there, and thank you for posting your question here on brainly.
Since we know what both of the exponents are, we can rewrite the equation for it.
3 * 2 - (-4)
We can evaluate from here.
I can see we have a positive number subtracting a negative number.
Use the rule where x - (-y) = x + y
2 * 3 + 4
Now we can get solving.
2 * 3 ==> 6
6 + 4 ==> 10
10 is the final answer.
Hope this helps! ☺♥
Answer:
Infinite solutions

2=2 is what is ends up as
Answer:
B.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −AB.
Step-by-step explanation:
A is being moved to the other side of the equation so it has to be negative and is multiplied by B since the y value has to be divided to equal the base of y not 9y but y.
-2x^2 + 3x - 9 = 0
The quadratic is not factorable so quadratic formula must be used.
x = (-b + - √(b^2 - 4ac))/2a
a = -2, b = 3, c = -9
x = (-3 + - √(9 - 4*-2*-9))/-4
x = (-3 + - √(-63))/-4
x = -3 + - 3i√7
--------------
-4
x = 3 + 3i√7 x = 3 - 3i√7
------------ ------------
