Answer:

x+2

5x-2

Step-by-step explanation:

There is only 2 binomials that will multiply together that will give the given trinomial.

ax^2+bx+c

5x^2+8x-4

Goal: Find two numbers that multiply to be a*c and add up to be b.

We will use this goal to factor our trinomial.

a=5

b=8

c=-4

--------

a*c=-20

b=8

Can you think of two numbers that multiply to be -20 and add up to be 8? I hope you said 10 and -2.

So we are going to replace 8x with -2x+10x.

5x^2+8x-4

5x^2-2x+10x-4

We are going to pair the first terms together and the second two terms together like so:

(5x^2-2x)+(10x-4)

Now we are going to factor each pair.

x(5x-2)+2(5x-2)

(5x-2)(x+2)

So (x+2) is a factor of the given trinomial and (5x-2) is a factor of the given trinomial.

You have two exponential functions. One function has the formula g(x) = 3(2 x ). The other function has the formula h(x) = 2 x+1
Alika [10]
The answer:

the main formula which should be used to reply this is:

g(x) - h(x) = (g-h) (x)

if the question does mean <span> g(x) = 3(2 ^ x )
</span>
k(x)= (g – h)(x) = 3(2 ^x ) - 2 ^(x+1)

 and we know that because of   a^x+p = a^*a^p

=3(2 ^x ) - 2 ^(x)2^1=(2 ^x )(3 - 2^1)

=(2 ^x )(3 - 2^1)= 2 ^x 

the answer is <span>k(x) = 2^x</span>

The washing machine had a selling price of P4,792. It had been marked up by P1,248. What was the cost? What was the mark-up rate
LUCKY_DIMON [66]

Answer:

The cost of the washing machine is P 3,544

The mark-up rate is 35.21%

Step-by-step explanation:

1. We want to calculate the cost

Mathematically, this is the difference between the selling price and the mark up

We have this as;

4,792 - 1,248 = P 3,544

2. Here, we want to calculate the mark-up rate

Mathematically, this is the percentage of mark-up

That is;

mark-up/cost price * 100%

: 1,248/3,544 * 100% = 35.21%
