Answer:
k = 4
Step-by-step explanation:
-9 +8k = 7+4k
Subtract 4k from each side
-9 + 4k = 7
Add 9 to each side
4k = 16
Divide by 4
k = 4
Plug in the value you got for k:
-9 + 8(4) ? 7 + 4(4)
-9 + 32 ? 7 + 16
23 ? 23
23 = 23
First you would add the two angles together to get 105. The. you do 180-105 to get 75. That is the missing angle. From there you would correspond the angles with the sides. Therefore the answer is Angle AB, angle BC, angle CA. these are in order from shortest to longest
Answer:
I’m pretty sure that’s - 11/3 .
Step-by-step explanation:
Answer:
you need to find the vertex, y-intercept, x-intercept, etc in order to create the equation.
Step-by-step explanation:
standard form for quadratic equations should look like this:
f(x)= ax^2+bx+c
(The graph is really blurry, try posting just the graph so I can see it closer if you still need help setting up the equation.)
