Given the function f(x) = 2(x + 8), find x if f(x) = 12.A) 2
B) 40
C) −2
D) 14

Answers

Answer 1
Answer:

Answer:

f(x)= 2 × (x+8)------(1)

f(x)=12---------(2)

Equating (1) and (2)

⇒2×(x+8)=12

⇒Using distributive property of multiplication with respect to Addition

⇒2 x +16=12

⇒2 x+16-16=12 -16-----[Subtracting 16 from both sides]

⇒2 x= -4

Dividing by , 2 ,on both sides

⇒x= -2

Option C: -2
Answer 2
Answer: f(x) = 2(x+8)
12 = 2x + 16
 2x = 12 - 16
 2x = -4
   x = -2

What is the midpoint of the segment shown below?

Answers

Answer:

It is C (4,3). Hope it helps.

Answer:

C. (4,3)

Step-by-step explanation:

To find the midpoint you must individually add the X's and the Y's and divide by 2. For example in this case, -2+10=8 divide by 2 and get 4. Then 3+3=6 divide by 2 is 3. It's that simple.

Which equation shows the quadratic formula used correctly to solve 7x2 = 9 + x for x?

Answers

For future reference, use a * to show the multiplication sign because in math x is a variable. 7*2 = 9 + x

Now multiply 7*2= 14

14 = 9 + x

Now subtract 9 from both sides to isolate the x

You and two friends visit a pizza shop. There are 13 toppings. 8 toppings are meat and the rest are vegetable. each of you order a different topping (No Repeats) at random. what is the probability that your group orders only meat toppings

Answers

The probability of the first person ordering a meat topping would be 8/13 because 8 are meat out of the possible 13 toppings.
The probability of the second person ordering a different meat topping would be 7/12 because there are 7 other meat options out of now 12.
The probability of the third person ordering a different meat topping would be 6/11.
Multiply these fractions together. 8/13 x 7/12 x 6/11 = 28/143

Answer:

28/143

When it goes on sale for $1,600, Mikah buys a new plasma television that is valued at $1,800. He takes $300 from his savings account to use as a down payment and finances the rest. Choose the true statement.a.
Mikah's assets increased by $1,300.
b.
Mikah's assets increased by $1,500.
c.
Mikah's assets increased by $1,600.
d.
Mikah's assets increased by $1,800.

Answers

Mikah's assets increased by $1,300 option (a) Mikah's assets increased by $1,300. is correct.

What is future value?

Based on an estimated growth rate, the future value is the amount that an asset will be valued at a future date. The computation assumes that at the start date, a fixed amount of cash is made available for investment and that it increases at a constant rate until the selected future date.

It is given that:

Mikah buys a new plasma television that is valued at $1,800.

He takes $300 from his savings account to use as a down payment and finances the rest.

As we know,

Net increase in asset = Purchase value of television − Value used from

savings account

Net increase in asset = $1600 - $300

Net increase in asset = $1300

Thus, Mikah's assets increased by $1,300 option (a) Mikah's assets increased by $1,300. is correct.
