Answer:

(1,-1)

Step-by-step explanation:

if its asking for a reflection on the x-axis, change the y's to the opposite of what it is.

Example, (5,6) change it to (5,-6)

its the same thing for the reflection on the y-axis

(7,-8) change it to (-7,-8)

Five times the difference of twice a number and twelve is negative twenty. Find the number. I need help with this guys please so

Lilit [14]

Answer:

The number is 4.

Step-by-step explanation:

The difference of twice a number and 12 is 2x - 12.

Multiplying by 5 gives 5(2x - 12)

So 5(2x - 12) = -20

Solving for x

10x - 60 = -20

10x = -20 + 60 = 40

x = 40/10

x = 4.

What are the solutions of the equation 9x^4 – 2x^2 – 7 = 0? Use u substitution to solve.

Debora [2.8K]

$9x^4 - 2x^2 - 7 = 0 \\ \text{substitution: } x^2=t, \ \ t\ \textgreater \ 0\\ 9t^2-2t-7\ \textgreater \ 0 \\ D=b^2-4ac=(-2)^2-4*9*(-7)=4+252 = 256 \\ t_{1,2}= \frac{-bб \sqrt{D} }{2a}= \frac{2б 16 }{18} \\ t_1=- \frac{14}{18} \ \ \ \ \O \\ \boxed{t_2=1} \\ \\x^2=1\\x=б \sqrt{1} \\ x=б1$
