If f(x) = -3x - 5 and g(x) = 4x - 2, find (f - g)(x).

A. (f- g)(x) = -7x - 3

B. (f- g)(x) = x - 3

C. (f - g)(x) = -7x + 3

D. (f- g)(x) = x - 7

**Answer:**

A. (f-g)(x) = -7x -3

**Step-by-step explanation:**

(f -g)(x) = f(x) -g(x) = (-3x -5) -(4x -2)

= -3x -5 -4x +2

= -3x -4x -5 +2

** (f -g)(x) = -7x -3**

Please solve this equation: 3 + 4 = 21; 2 + 5 = 14; 7 + 7 = 98; 8 + 6 = ?

**Answer:**

112

**Step-by-step explanation:**

It appears that the relation is f(a, b) = a(a+b).

f(3, 4) = 3(3+4) = 21

f(2, 5) = 2(2+5) = 14

f(7, 7) = 7(7+7) = 98

** f(8, 6) = 8(8+6) = 112**

__

The symbol "+" has apparently been repurposed from its usual meaning in math. It is being used as an infix operator with two arguments. We have shown the relation above as a function f with two arguments (a, b). In our definition ...

f(a, b) = a(a+b)

the symbol "+" has its usual meaning.

Shelly has a plan to save $500 for a trip that is 8 weeks away. She already has $50 in her

account. How much will she need to save weekly to meet her goal?

**Answer:**

She will still need about 450$

**Step-by-step explanation:**

So from what I have learned, she will need to work in order to get the money, but even when she is working, she may have expenses to pay and she may not make it, but she will because she can do loans and when she earns the money from loans, then she can pay, then she may have left over money she can use while on trip.

I don’t know but it’s about 400 or 450

All the best for ur exams .........Mine are going on too btw.......

can someone help me with this

**Answer:**

**Step-by-step explanation:**

The relevant relation is "the exterior angle is equal to the sum of the remote interior angles." That means ...

** (4x +8)° = (2x +3)° +51°** . . . equation to solve for x

2x = 46 . . . . . . . . . . . . . divide by °, subtract 8+2x

x = 23 . . . . . . . . . . . . divide by 2

Then the **exterior angle** is ...

(4x +8)° = (4(23) +8)° = **100°**

_____

*Additional comment*

Instead of solving for x, we can solve for (2x+3). We can do that by subtracting 5+2x from both sides to get 2x+3 = 49. Then the exterior angle is the sum 49+51 = 100 degrees. (We don't actually care about the value of x.)

hope I helped! I need to write more words so I can send this

**Answer:**

The answer is A

**Step-by-step explanation:**

|6x + 3| = 27

Use the definition of absolute value6x + 3 = 27

6x + 3 = -27

Subtract three from both sides of the equation.6x = 24

6x = -30

Divide both sides by 6.x = 4

x = -5

So:

x = 4, -5

Anne pays cash for a Tv. The store owner gives her a 10% discount. She pays $702. How much was the price of the Tv before a discount?

**Answer:**

$780

**Step-by-step explanation:**

P = Original Price

P (100% - 10%) = $702

P (90%) = $702

(P (.9)) / .9 = $702 / .9

P = $780

Check answer:

$780 (90%) = $702

X > 0 and y > 0 0 < x â‰¤ 20 and y > 60 x > 0 and y < 20 0 < x â‰¤ 20 and 0 < y â‰¤ 60.

The **correct option **is **D**.[tex]0< x\leq 20[/tex] and [tex]0< y\leq 60[/tex].

Given, [tex]x[/tex] **represent **the number of **male birds **and [tex]y[/tex] represent the number of **female birds**.

The flock needs to have exactly **three times **more **females **than males to **thrive**.

So, in equation form we have,

[tex]y=3x[/tex]........(1)

Since, The **zoo **only has room for a **maximum **of **20 male birds.
**

So, we can write the **inequality **for [tex]x[/tex] as,

[tex]0< x\leq 20[/tex]......(2)

Since The **maximum number **of male birds is **20**, so for [tex]x=20[/tex]

y will be,

[tex]y=3\times 20\\[/tex]

[tex]y=60[/tex]

**Hence, **The **maximum number **of female **birds **is **60.
