7(2x+5)=4x-9-x
14x+35=3x-9
11x = -44
x = -4
7(2*-4+5)=4*-4-9--4
7(-3)=-21
-21=-21. so it checks out and x = -4
Answer:
(3,0) the graph touches the x-axis
Step-by-step explanation:
the graph of
we need to check what happens to the graph near the point (3,0)
In f(x) we have (x-3)^2
LEts plug in 3 for x and check
y=0, so (3,0) is one of the zero of the given f(x)
In f(x) we have
Exponent is 2 that is even. It means the multiplicity is even.
When the multiplicity is even then the graph touches the x axis but does not cross x axis
So at (3,0) the graph touches the x-axis
Answer:
is there answer choices
Step-by-step explanation:
The answer will be (B) -9 because since the angles are equal, the two sides must be equal also.
Therefore
x+16=7
And then
x= 7-16
x=-9
