Answer:1
Step-by-step explanation:
8÷5=1.6 but you don’t want the 6 or the decimal (.) so it’s 1!
Answer:
right across my mom is the best I can get in a lot and I don't think so
Step-by-step explanation:
carbon fiber and fiber is not a problem in the morning and it doesn't work for me because I am sorry to get the best results in the process but it will get worse when I have a good idea to make a difference and 87inches will be there for me and I have no problems in my body step and the symptoms of my illness will have 7 or so severe symptoms that may 6PM up with my symptoms of depression and anxiety and depression in my heart as a child in a very much and very much
Sorry, it's late, and I'm a bad explainer.
The error is adding (2x-12) with x and 30. This is wrong because you are adding the angles inside the triangle and you are assuming that (2x - 12) is the unlabeled angle INSIDE the triangle, when it is the exterior angle/outside of the triangle.
A straight line is also 180°.
(2x - 12) + ? = 180
30 + x + ? = 180
If you look at the equations, and put parentheses around 30 + x, (30 + x) and (2x - 12) should be the SAME NUMBER. So you could set them equal to each other to find x. (or you could also look at the picture and see that they both need/are missing the same angle)
2x - 12 = 30 + x
x = 42
Now you plug 42 into the exterior angle equation
2(42) - 12 = 84 - 12 = 72°
Answer:
y =
(x - 5)² - 2
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (5, - 2), thus
y = a(x - 5)² - 2
To find a substitute (7, 0) into the equation
0 = a(7 - 5)² - 2
0 = 4a - 2 ( add 2 to both sides )
2 = 4a ( divide both sides by 4 )
a =
= 
y =
(x - 5)² - 2 ← in vertex form
