Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.

1. 4x + 5y
kvv77 [185]
<h3><u>Solution</u><u> </u><u>:</u><u>-</u><u> </u></h3>

  • When x = 6 and y = 1.

1) 4x + 5y

→ 4*6 + 5*1

→ 24 +5 = 29

2) 2x (20-y)

→ 2*6 (20-1)

→ 12 *19 = 228

3) x ÷ 3 + y

→ 6 ÷ 3 + 1

→ 2 +1 = 3

4) 4y ÷ 2 + (8x + 10)

→ 4*1 ÷ 2 +(8*6+10)

→ 2 + (48+10)

→ 2 + 58

→ 60

5 ) 5. Patty made $34 baby sitting on each of 3 weekends. If she spent $50 on gifts for her family, how much money does she have left?

Money made each weekend = $34

Money made in 3 weekend = $34*3 =$102

Money spent = $50

Therefore ,

→Money left = Money made in 3 weekends - Money spent

→ Money left = $102 - $50 = $52

6.Carlos solved 20-(2x6) + 8 divide 4 = 29. Is this the correct answer? ( In attachment it's written 29 and not 28 .)

Given equation is ,

→ 20 - (2 × 6) + 8 ÷ 4 = 29

Solve inside the brackets ,

→ 20 - 12 + 8 ÷ 4

Perform division ,

→ 20 -12 + 2

Perform addition ,

→ 22 - 12

Perform subtraction,

→ 10

<u>No , he is wrong the answer should have been 10 but he got 29 .</u>

1) If a polynomial is divided by a binomial and the remainder is 0, what does this tell you about the relationship between the b
klemol [59]
<h2>The binomial is a factor of the polynomial.</h2>

Step-by-step explanation:

If a polynomial is divided by a binomial and the remainder is 0.

Then the binomial is a factor of the polynomial.

If a polynomial g(x) is divided by (x-a) ,it gives g(a) as remainder

Then g(x) = (x-a) Q(x) + g(a)

Hera g(a) = 0

So, g(x) = (x-a) Q(x)

It shows that (x-a) is a factor of g(x)

Replace * with a monomial so that the trinomial may be represented by a square of a binomial:
coldgirl [10]

Answer:

Since:

a^2-2ab+b^2 = (a-b)^2

and

a^2+2ab+b^2 = (a+b)^2

We need to find value of * which is 2ab

In your equation = \sqrt{6.25}  = 2.5 and \sqrt{1/4} = 0.5\\Now 2ab = 2 * 2.5 * 0.5\\ = 2.5\\\\\\* = 2.5ab
