Answer 1

Answer:

7

Step-by-step explanation:

If you have a TI-83+ you can press y= and plug that in. Then fin where the x axis meets 98 which is 7.

Answer 2

$\text{Hey there!}$

$\text{\underline{DIVIDE} both sides by the number 2 on your sides!}$

$\text{Like:}\bold{\frac{2x^2}{2}=\frac{98}{2}}$

$\bf{Cancel:\frac{2}{2}\ because\ it \ equals \ 1}$

$\text{Keep:}\frac{98}{2} \text{ because it helps us solve for our answer!}$

$\bf{\frac{98}{2}=49}$

$\text{Problem becomes:}\bf{\ x^2=49}$

$\text{Take the root of the newer equation:}\bf{\ x=\pm\sqrt{49}}$

$\text{Solve that}\uparrow \text{and we will get the value of x}$

$\boxed{\boxed{\boxed{\text{Answer: x = 7 or x = -7}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
