I just learned this
9-3= 6
10-40= -30
so
6/-30= -1/5
So the answer is C
B, there's only two kinds of acute triangles ands that's a 45,45,90 and a 30,60,90.
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
Answer:
-3x+2y greater than or equal to 7
Step-by-step explanation:
we can take away the first and second cause the line is full and not dotted. with desmos, i plugged the equation in and found that the third equation matches the picture
