Graph the equations to solve the system. y = x + 4 y = -x - 6 choose the correct answer a.) solutions: all numbers on the line

1 answer:

8 0

Y = x + 4
y = -x - 6

x + 4 = -x - 6
x + x = -6 - 4
2x = -10
x = -10/2
x = -5

y = x + 4
y = -5 + 4
y = -1

one solution : (-5,-1)

Venus is the planet that comes nearest to the Earth its closest position is about 38000000 kilometers from earth. write this num

amm1812

always put the 1st number you would like to turn to scientific notation

so the 1st number here is 3

then you turn 8 into a decimal because it is the only other number that isnt 0 and then it is 3.8

you then count every number after 3 including 8 which is

then you always put 10 x whatever number you are doing but right now it is 3.8

and the answer is

10 x 3.8^7

Which of the following is an extraneous solution of the square root of -3x-2=x+2

yarga [219]

Answer:

x=-6 is an extraneous solution

Step-by-step explanation:

we have

$\sqrt{-3x-2} =x+2$

squared both sides

$-3x-2=(x+2)^2$

$-3x-2=x^2+4x+4$

$x^2+7x+6=0$

solve the quadratic equation by graphing

The solution is x=-6 and x=-1

see the attached figure

<u><em>Verify each solution</em></u>

substitute the value of x in the original expression

For x=-6

$\sqrt{-3(-6)-2} =-6+2$

$\sqrt{16} =-4$

$4=-4$ ----> is not true

Is an extraneous solution

For x=-1

$\sqrt{-3(-1)-2} =-1+2$

$\sqrt{1} =1$

$1=1$ ----> is true

Is the solution
