13/250 as a decimal is 0.052
Answer:
36°, 42°, 72°, 102°, 108°
Step-by-step explanation:
Angles at a point = 360°
Therefore:
(3x - 6) + x + 3x + 2x + (x + 6) = 360°
Open parthenogenesis
3x - 6 + x + 3x + 2x + x + 6 = 360
Add like terms
10x = 360
Divide both sides by 10
x = 36
✔️Value of each angle:
Plug in the value of x in each expression
x = 36°
3x - 6 = 3(36) - 6 = 102°
3x = 3(36) = 108°
x + 6 = 36 + 6 = 42°
2x = 2(36) = 72°
Axis of symmetry =-b/2a
so subsitiute
a=1,b=5
-5/2
i believe thr axis of symmetry is at -2.5
Answer:
Step-by-step explanation:
We are asked to solve the given equation: 
.
To solve this equation we will combine like terms by moving all the terms containing x to the left hand side of equation and terms without x to right hand side of equation.
Let us add 8x to both sides of our equation.
Let us subtract 8 from both sides of our equation.
Upon dividing both sides of our equation by 6 we will get,
Therefore, the value of x equals 1 will satisfy our given equation.
Intersecting the y axis means x is o, so you plug x=0 in the equation and solve for y. if y has real solutions, then the answer is yes.
Let's find out:
0+y^2-6y=-9
y^2-6y+9=0
(y-3)(y-3)=0
y=3
3 is a real number, so yes, the equation intersects the y axis at (0,3)
