A)
you need to know where a vertex goes on a isosceles triangle...
I attached a picture that explains it.....
you also want to label triangle.... XYZ
I put a picture on of how you should of labeled the triangle...
B)
so we need to find Measure for each angle.... REMEMBER: A triangle angles needs to = 180.
so your equations will need to be equal to 180.
4x+4+2x+2+7x-8=180
so we combine liked terms
4x+2x+7x=13x
4+2-8=-2
13x-2=180
+2 +2
13x=182
/13 /13
x=14
now you plug in X
4(14)+4= 60
2(14)+2= 30
7(14)-8= 90
now you want to check you answers so add them up to see if your answers equal 180...
60+30+90=180
to be continued.... i do second question on a second answer since i dont want pictures to get mixed up
the value of the car will be 3250 after 5 years
Step-by-step explanation:
the value of the car = 13000
rate of interest = 15%
time = 5 years
in 5 years the car will depreciates = 13000 X 15% X 5
=
= 9750
after 5 years the value of the car is = 13000 - 9750 = 3250
Hey there! :)
Answer:
Domain: (-∞, ∞)
Range: [-1, ∞)
Step-by-step explanation:
This is an absolute-value function. (Graphed below) The vertex is at (-3, -1) which consists of the minimum y-value of the function. Therefore:
Domain: (-∞, ∞)
Range: [-1, ∞)
