Complete the table of inputs and outputs for the given function. g(x)=-4x-1

Radda [10]

Answer:

(x, y) = (-2, 7), (0, -1), (3, -13), (-1, 3)

Step-by-step explanation:

To fill in the y-values, you need to put the x-value in the equation and evaluate.

for x=0

y = -4(0) -1 = -1

for x=-1

y = -4(-1) -1 = 4 -1 = 3

To fill in the x-values, we can solve for x and then do as we did above.

y = -4x -1

y +1 = -4x . . . . add 1

-(y +1)/4 = x . . . divide by -4

for y=7

x = -(7 +1)/4 = -2

for y=-13

x = -(-13+1)/4 = -(-12/4) = 3

Then the table is ...

$\boxed{\begin{array}{cc}x&g(x)\\-2&7\\0&-1\\3&-13\\-1&3\end{array}}$

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
