Answer:
18
Step-by-step explanation:
I'm not sure but there is a rule that the sum of out side angles of each shape is 360
saying that 360/5= 72
so if we continue the lines it will be 36 degree to of the outside angles and 18 degree each
Not let's make that into another rectangle (The one that is upside down)
180- (2*18)= 144
So the big degree is 144
now again
(180-144)/2=18
So each of those small red angles are 18
Answer: 1/2
Step-by-step explanation:
30x + 18 = 35-4x
collecting like terms
30x + 4x = 35-18
34x = 17
divide both sides by 34
34x/34 = 17/34
x = 1/2
Just one. the solution is 11/3
You need to find points where the line g(x) intercepts the quadratic function f(x) in one and only one point.
Then 3x^2 + 4x -2 = mx - 5
solve 3x^2 + 4x - mx -2 + 5 = 0
3x^2 + (4 - m)x + 3 = 0
In order to there be only one solution (one intersection point) the radicand of the quadratic formula must be 0 =>
b^2 - 4ac = (4 - m)^2 - 4(3)(3) = 0
(4 - m)^2 = 24
4 - m = +/- √(24)
m = 4 +/- √(24) = 4 +/- 2√(6)
Then m, the slope of the line, may be 4 + 2√6 and 4 - 2√6
Answer: c = 8
Step-by-step explanation:
Simplifying
9c + -3c = 48
Combine like terms: 9c + -3c = 6c
6c = 48
Solving
6c = 48
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Divide each side by '6'.
c = 8
Simplifying
c = 8
