GREYUIT [131]

All you have to do is solve for x. See the following steps below.

Step 1. Subtract $\frac{5}{3}$ from both sides

$X= 15-\frac{5}{3}$

Step 2. Simplify $15- \frac{3}{5}$ to $\frac{40}{3}$

$X= \frac{40}{3}$

Find the distance between the points of intersection of the graphs of the functions.

Viefleur [7K]

Answer:

Find the value of x and y in coordinate form, that'll be the point of intersection.

Question 1

${ \rm{y = {x}^{2} - 3x + 4 }} \\ { \boxed{ \tt{but \: y = x + 1 \: }}} \\ \\ { \rm{(x + 1) = {x}^{2} - 3x + 4 }} \\ \\ { \rm{ {x}^{2} - 4x + 3 = 0 }} \\ \\ { \rm{(x - 3)(x - 1) = 0}} \\ \\ { \boxed{ \rm{x_{1} = 3 \: \: and \: \: x _{2} = 1}}} \\ \\ { \boxed{ \tt{remember \: y = x + 1}}} \\ \\ { \rm{y _{1} = 4 \: \: and \: \: y _{2} = 2 }}$

Therefore, points of intersection are two

Answer:  (3, 4) and (1, 2)

Question 2:

Following the steps as in question 1

${ \rm{y = {x}^{2} - 4}} \\ \\{ \rm{2x - 4 = {x}^{2} - 4}} \\ \\ { \rm{ {x}^{2} = 2x }} \\ \\ { \boxed{ \rm{x = 2}}} \\ { \tt{remember : \: y = 2x - 4 }} \\ { \boxed{ \rm{y = 0}}}$

Answer: (2, 0)

How do you simplify 8 to the -2 power

Tems11 [23]

IF you have a scientific calculator that would REALLY be handy here but if you don't then um.... I have no clue what to tell you. Sorry!!

The answer to 8 raised to the -2 power is .015625
Most likely you should round it out so it would be .016
