1. What is the solution of n² – 49 = 0? (1 point)
maks197457 [2]

Answer:

1. n=\pm7

2. x=\pm7i[tex]3.[tex]\pm 12x =a

4. 22

Step-by-step explanation:

1. n^2 - 49 = 0

n^2 =49

n= \sqrt{49}

n=\pm7

2. x^2+64 = 0

x^2 =-64

x= \sqrt{49}

x=\pm7i[tex]3. Area of square = [tex]a^{2}

Where a is the side

We are given an area o square = 144x^{2}

So, 144x^{2}=a^{2}

\sqrt{144x^{2}}=a

\pm 12x =a

4. We are given that the solution of quadratic equation -9 and 9

So, equation becomes:

(x+9)(x-9)=0

x^2- 81=0

So, in the given equation x^2 + z = 103

z should be the number from which if we subtract 103 so we get 81

Substitute z = 22

x^2 + 22 = 103

x^2 + 22 -103=0

x^2 -81=0

Thus the value of z is 22

-4x+8y=24 in slope intercept form
omeli [17]

Answer:

y=1/2x+3

Step-by-step explanation:

-4x+8y=24

Slope-intercept form: y=mx+b

Add -4x on each side

-4x+8y=24

+4x       +4x

8y=4x+24

Divide by 8 on each side

<u>8y</u>=<u>4x+24</u>

8        8

y=4/8x + 3

Simplify 4/8x

y=1/2x+3
