Answer:
I got 14 x -2
Step-by-step explanation:
to add all of the like terms you get:
2x + 7x + 5x = 14x
then add the other terms you get:
-6 + 4 = -2
when adding the two parts together you get:
14x -2
Am pretty sure this is right, sorry if its wrong
You have to find the least common variable, and that would be 10. multiply 2/10 by 10 to get 20/100. 4/100+20/100=24/100. it's C
Answer:
Hello There
x=5 is a vertical line whose slope is undefined. Any line parallel to it must also be vertical. A vertical line that passes through (-8,4) is x=-8.
It may be helpful to you to graph the lines to get a visual representation.
I hope this helps you.

Answer:
x = 20
Step-by-step explanation:
The sum of the given angle expressions is 90°, the measure of the right angle:
x + (3x +10) = 90
4x = 80 . . . . . . . . . subtract 10
x = 20 . . . . . . . . . . divide by 4
Answer: a) k >4.08
b) k = 4.08
c) k<4.08
Step-by-step explanation:
Since we have given that
a) For what values of k will the function have no zeros?
It mean it has no real zeroes i.e. Discriminant < 0
As we know that
Here, a =-3
b = 7
c = -k
So, it becomes,
b) For what values of k will the function have one zero?
It means it has one real root i.e equal roots.
So, in this case, D = 0
So, it becomes,
c) For what values of k will the function have two zeros?
It means it has two real roots.
In this case, D>0
So, it becomes,
Hence, a) k >4.08
b) k = 4.08
c) k<4.08
