Solve 8(x+2)=36.......

brilliants [131]

We have to use the Distributive Property in this equation.
By the Distributive Property,
$8(x+2)=36
$
becomes
$8x+16=36.$
Now we need to isolate x. Remember PEMDAS?
$8x=20$
$x=20/8$
Simplify the right side.
$x=10/4$
$x=5/2$

F(x) = x^2 -7x +14, g(x) = 4x -9 <br><br> Find (g ° f)(x)

adelina 88 [10]

Answer:

Set up the composite result function.

g(F(x)) Evaluate g(x2−7x+14)

by substituting in the value of F into g.

g(x2−7x+14)=4(x2−7x+14)−9

Simplify each term.

g(x2−7x+14)=4x2−28x+56−9

Subtract 9 from 56.

g(x2−7x+14)=4x2−28x+47

Reggie Means invested part of $31,000 in municipal bonds that earn 7.5% annual simple interest and the remainder of the money in

insens350 [35]

Answer:

Principal Invested in Municipal Bonds is $16,000

Principal Invested in Corporate Bonds is $15,000

Step-by-step explanation:

If;

Principal Invested in municipal bonds = a

Principal Invested in corporate bonds = b

then we have;

a + b = $31,000 --------------------------------Equation 1

0.075a + 0.085b = $2,475 ---------------Equation 2

From equation 1 we have;

a = 31,000 - b

By putting the values of a in Equation 2 we get;

0.075 (31,000 - b) + 0.085b = 2,475

2,325 - 0.075b + 0.085b = 2,475

0.01b = 150

b = $15,000

By putting the values of b in equation 1 we get;

a = $16,000

For which value of x is the equation 3(3 + x) = 15 + x true?

seraphim [82]

<u>Answer:</u>

x=3

<u>Step-by-step explanation:</u>

3(3 + x)=15+x

<u>distribute</u>

9 + 3x= 15+x

<u>subtract x from each side</u>

9+3x-x = 15

9+2x = 15

<u>subtract 9 from each side</u>

9+2x-9 = 15-9

2x = 6

<u>divide by 2</u>

2x/2 = 6/2

x=3
