Answer:

x=4

Step-by-step explanation:

To remove the radical on the left side of the equation, square both sides of the equation.

√x+4−72=12x+4-72=12

Simplify each side of the equation.

x−3=1x-3=1

Move all terms not containing xx to the right side of the equation.

x=4

Can some help me fast!
Mice21 [21]

Answer:

5x +2y =38

5(6) +2y = 38

30 +2y= 38

2y= 8

y= 4

(6, 4)

5(0) +2y =38

2y= 38

y= 19

(0,19)

5(-2) +2y= 38

-10 +2y =38

2y= 48

y=24

(-2,24)

What is the vertex of the quadratic function f(x) = (x – 8)(x – 2)?
LekaFEV [45]
Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9

vertex is at (5,-9)

the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever


verrtex is at (5,-9)

What is the solution to the system of equations below?
kifflom [539]

Answer:

(-5,-14)

Step-by-step explanation:

To find the solution of the system of two equations

\left\{\begin{array}{l}y=4x+6\\y=2x-4\end{array}\right.

equate right sides of these two equations:

4x+6=2x-4

Rewrite terms with x into the left side and without x into the right side:

4x-2x=-4-6\\ \\2x=-10\ [\text{divide by 2}]\\ \\x=-5

Substitute x=-5 into the first equation:

y=4\cdot (-5)+6=-20+6=-14

The solution is (-5,-14)
