Answer:

x = -11

Step-by-step explanation:

To find the zero of this function, factor the equation:

g(x) = x^{2} +22x+121

g(x) = (x + 11) (x + 11)

g(x) = (x+11)^{2}

The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.

Solve by substitution
goldenfox [79]
Ok here it is:
4x-5y=40
2x+10y=20
I used the second equation and decided to get x
2x+10y=20
Subtract 10y from both sides.
2x=-10y+20
Divide both sides by 2
x=-5y+10
Put that in for x for first equation
4(-5y+10)-5y=40
Distribute the 4
-20y+40 -5y =40
Combine like terms
-25y+40=40
Subtract 40 from both sides
-25y=0
Divide by -25 on both sides
y=0
Substitute the y in for the 2nd equation
2x+10(0)=20
2x=20
Divide both sides by 2
x=10
So x=10 and y=0

Since variables x and y are in direct proportion,

Y = 12.5/25 x 40
Y = 0.5 x 40
Y = 20.

Aidan and ethan were solving math problems together for homework adian did 410×10 to the fourth power would have 4 zeros in the
agasfer [191]

Answer:

No.

Step-by-step explanation:

410•10=4100 and 4100=41•100. We just need to focus on the 100. 100•100•100•100=100,000,000 which has 8 zeros, not 4 zeros.

If the measure of arc AD is 65 degrees and the measure of arc BC is 45 degrees, what is the measure of angle BEC?
krek1111 [17]

Answer:

\angle BEC=55 \textdegree)

Step-by-step explanation:

From the question we are told that:

Arc AD =65 \textdegree

Arc BC =45 \textdegree

Given The angle of intersecting chords theorem

Generally the equation for angle BEC is mathematically given by

 \angle BEC=\frac{1}{2} (\angle of arc AD+\angle of arc BC)

 \angle BEC=\frac{1}{2} (65 \textdegree+45 \textdegree)

 \angle BEC=55 \textdegree)

If you're looking for the whole angle i'm pretty sure it's 74 degrees. If you're solving for x, x=8
