Slove system of equations y=2x-3 y=x^2-2x-8
Fiesta28 [93]

Answer:

2 solutions:

x=5 and y=7

x=-1 and y=-5

Step-by-step explanation:

y=2x-3

y=x^2-2x-8

y=y   so:

2x-3=x^2-2x-8

simplifying to:

x^2-4x-5=0

factoring to:

(x-5)(x+1)=0

x=5 or x=-1

if x=5 then y=2(5)-3=7

if x=-1 then y=2(-1)-3=-5

Zigmanuir [339]

Answer:

2:25pm

Step-by-step explanation:

The time given is 5pm to catch the train back to school;

Amount of time for the tour  = 1hr 45min

                                               = 105min

Amount of time at gift shop  = 30min

Amount of time to save  = 20min

 Total time = 105min + 30min + 20min  = 155min

So;

Total time  = 2hr 35min

So;

        5pm - 2hr 35min  = 2:25pm

What is f(5) if f(1) = 3. 2 and f(x 1) = Five-halves(f(x))?
stealth61 [152]

Function assign value from one set to another. The value of f(5), if f(1) = 3.2 and f(x+1) = Five-halves(f(x)) is 125.

<h3>What is Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

As it is given the value of the function f(1) is 3.2, while the value of f(x+1) is f(x+1) = \dfrac{5}{2}[f(x)], therefore, in order to find the value of f(5), we need to calculate the value of f(4).

f(2)

f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(2)=f(1+1) = \dfrac{5}{2}[f(1)]\\\\f(2) = 2.5 \times 3.2\\\\f(2) = 8

f(3)

f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(3)=f(2+1) = \dfrac{5}{2}[f(2)]\\\\f(3) = 2.5 \times 8\\\\f(3) = 20

f(4)

f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(4)=f(3+1) = \dfrac{5}{2}[f(3)]\\\\f(4) = 2.5 \times 20\\\\f(4) = 50

f(5)

f(x+1) = \dfrac{5}{2}[f(x)]\\\\f(5)=f(4+1) = \dfrac{5}{2}[f(4)]\\\\f(5) = 2.5 \times 50\\\\f(5) = 125

Hence, the value of f(5), if f(1) = 3. 2 and f(x+1) = Five-halves(f(x)) is 125.
