4(2x-9)+2 simplified

Answer:

Yes, it is a function

Step-by-step explanation:

This is a function since each x value, the number on the left in the paretheses only has one y value.

If any x had more than one y value, it wouldn't be a function.

Answer:

i think the answer is 7.9373

Step-by-step explanation:

so its the Herons Formula (when you know all 3 sides) so the formula would be

Area =  √  p  ( p − a )  ( p − b )  ( p − c )    

p is half the perimeter

or,

Distance between both points = 13

We have to find value of x[tex].[/tex]

Distance between two points can be measured by using this formula :

⭆ d = √[(x₂ - x₁)² + (y₂ - y₁)²]

⭆ 13 = √[(x - (-2))² + (-7 - 5)²]

⭆ 13² = (x + 2)² + (-12)²

⭆ 169 = (x + 2)² + 144

⭆ (x + 2)² = 169 - 144

⭆ (x + 2)² = 25

⭆ x + 2 = 5

⭆ x = 5 - 2

⭆ x = 3

The value of "x" will be "7".

Given:

When "m" is parallel, then

→      [tex]m_2=m_6[/tex]

By substituting the values, we get

→ [tex]6x+8=8x-6[/tex]

By adding "6" both sides, we get

→ [tex]6x+8+6=8x-6+6[/tex]

→      [tex]6x+14=8x[/tex]

By subtracting "6x" from both sides, we get

→  [tex]6x+14-6x=8x-6x[/tex]

→                   [tex]14=2x[/tex]

                      [tex]x = \frac{14}{2}[/tex]

                          [tex]= 7[/tex]

Answer:

[tex]12 + 5h \leq 18 + 3h[/tex]

Step-by-step explanation:

Given

Represent Derrick's with D and Pauline's with P

For D

Registration Fee = $12

Hourly Charges = $5

For P

Registration Fee = $18

Hourly Charges = $3

Required

Represent as an inequality such that D is at most of P

First, we need to represent both as an expression:

For D

[tex]D: 12 + 5h[/tex]

For P:

[tex]P:18 + 3h[/tex]

Since D is at most of P;

This implies that:

[tex]D \leq P[/tex]

So, we have:

[tex]12 + 5h \leq 18 + 3h[/tex]

Answer: Subtract 0.03.

Step-by-step explanation:

given data:

Cost of T-shirt one = $24.97.

cost of T-shirt two = $13.75.

peyton rounded the cost of the first T-shirt up to $25 ( by adding $0.03 ). The addeded the cost of the second shift to arrive at a total cost of $38.75 for both.

to find the exact amount of the two shirts, peyton needs to subtract 0.03 from the total amount.

= $38.75 – 0.03

= $38.72

The original amount of both T-shirt is $38.72.

Answer:

The answer is 12

Step-by-step explanation:

All you had to do is subtract 26.95 by 8.95 which is 18, and then you would divide 18 by 1.50 and your answer is 12!

$110 x 7 =$770. A weeks stay at the Plaza Hotel will cost $ 770.00. 7 days multiplied by $110 will cosr $770

Answer:

I think there is a missing “and” there: “If the sum of the square of the number and 4 times the number is 21, what is the number?”

If so, then we have: x² + 4x = 21, or x² + 4x - 21 = 0.

This factors as (x+7)(x-3) = 0, so x = -7 or x = 3.

Answer:

Rocket will hit the ground in 10.55 seconds.

Step-by-step explanation:

Let be [tex]y = -16\cdot x^{2}+157\cdot x +124[/tex], where [tex]x[/tex] and [tex]y[/tex] are time after launch and the height of the rocket, measured in seconds and meters, respectively. To find the time that the rocket will hit the ground, we need to equalize height to zero and solve the resulting expression:

[tex]-16\cdot x^{2}+157\cdot x + 124 = 0[/tex]

The quadratic function can be solved analitically by Quadratic Formula, that is to say:

[tex]x = \frac{-157\pm \sqrt{157^{2}-4\cdot (-16)\cdot (124)}}{2\cdot (-16)}[/tex]

Roots of the polynomial are, respectively:

[tex]x_{1} \approx 10.55\,s[/tex], [tex]x_{2}\approx -0.74\,s[/tex]

Only first root offers to us a reasonable solution. Hence, we conclude that rocket will hit the ground in 10.55 seconds.

Answer:

50°

Step-by-step explanation:

Hope this helps and is correct

60 degrees

This triangle is a right triangle, which means One angle measure of the triangle is 90 degrees. And the given angle is 40 degrees. The total sum of all the angles in a triangle is 180 degrees.

So if you add 40 + 90 + x = 180

You get 130 + x = 180

If you subtract 180 - 130

You get 60.

Answer:

E. People once thought animals were individually create by some superior.

But the solid creation of theory of origin of species by the naturalist Charles Darwin demonstrated a different theory.

Step-by-step explanation:

Before Charles Darwin several scientists were discussing the hypothesis of a theory of evolution. But it was Darwin whom put together all the information with reliable explanation and correlation between animal specialization and environment accordyinly with time.

He spent almost five years on board the ship HMS Beagle, crossing several continents, starting with South America. From there, he returned with dozens of specimens of living species, illustrations and fossils. Those specimens helped Darwin in his discoveries which originated the book On the Origin of Species published in 1859.

Answer:

Step-by-step explanation:

PIN stands for Personal Identification Number. Option d is correct.

An alphanumeric or numeric string called a personal identification number (PIN) is used to verify a person's identity in a system.

Automated Teller Machines (ATM) for a bank, are the primary use cases for PINs (ATM). PINs are frequently used in place of more complex passwords to unlock mobile devices and authenticate users to applications.

Along with the development of the ATM, PINs were invented in the UK. In 1967, Barclays debuted ATMs as a convenient way for consumers to obtain cash. They also introduced ATM check deposits, which made use of codes printed on checks to help correctly account for such transactions.
