If D = t +9t2 and C = t - t - 8, find an expression that equals D - 3C in standard form?

Answer:

$98

Step-by-step explanation:

Classic Car Monthly charges $49 for a 3-line classified ad. Each additional line costs $9.50. For an extra $30, a seller can include a photo. How much would a 5-line ad with a photo cost?

base,3-line cost: $49

additional cost for 2-lines: 2* 9.50 = $19

photo cost: $30

cost: 49 + 19 + 30 = $98

Hello!

We have the function f(x) = 3x.

First, let's replace where's f(x) by y:

f(x) = 3x

y = 3x

Now, let's swap the values of x and y:

y = 3x

x = 3y

Now we have to solve it to obtain y:

3y = x

y = x/3

So, we will have:

Image with the reasoning:

So, these equations are correct.

As it has no restrictions, this function is valid for all values of x.

Right answer: alternative A.

mRNA full form Messenger RNA (ribonucleic acid) which is a type of RNA found in cells.

A transcript of information from DNA. They carry the information from the DNA of  the nucleus of the cell to the cytoplasm where the proteins are manufactured. Thus it is also called  messenger RNA.

It carries genetic information which we will use to make proteins. They are necessary for protein formation.

In cells, mRNA  uses the information to make a map or a blueprint for making proteins. Once cells  finish making a protein, they break down the mRNA.

The y-intercept of the line y = 14 / 17 x + 14 is 14.

The equation of a line can be represented in different form such as slope intercept form, point slope form, standard form and general form.

Therefore, let's represent it in slope intercept form.

y = mx + b

After using the protractor we have come to find that DF is not an angle bisector of ∠HDJ. ∠JDF measures  27° and ∠FDH measures 22°.

An angle bisector is a ray, segment, or line that splits an angle into two equal-sized angles. A thing is divided into two equal parts when it is bisectored or bisectioned. In geometry, we frequently use a line or ray—known as an angle bisector—to divide a triangle and an angle.

The ray, line, or segment that divides an angle into two equal parts is known as the angle bisector in geometry. A 60-degree angle, for instance, will be split into two angles of 30 degrees each by an angle bisector. To put it another way, it separates an angle into two smaller congruent angles. An example of an angle bisector of AOB is shown below.

The solution for the system of equations is:

x = 0

y = 2

Given the pair of equations:

2x + 4y = 8 ........................................................(1)

x = 3y - 6 ............................................................(2)

Substitute the expression of x in (2) into (1)

2(3y - 6) + 4y = 8

6y - 12 + 4y = 8

6y + 4y = 8 + 12

10y = 20

y = 20/10 = 2 ......................................................(3)

Substitute the value of y in (3) into (2)

x = 3(2) - 6

= 6 - 6

= 0

Therefore,

x = 0, and y = 2

We know that ∠1 ≅ ∠4

As you determined ∠2 is the supplement of ∠1 and ∠3 is the supplement of ∠4, since ∠1 and ∠4 are equal, you can conclude that ∠2 and ∠3 are also equal.

Point R is the midpoint of XY, which indicates that it divides the line into two equal segments XR and RY.

Segment XR is formed by segments XP and PR, following the segment addition postulate you can determine that:

Segment RY is formed by segments RT and TY, so that:

Following the substitution postulate, if XR and RY are equal, then:

We know that XP ≅ TY, sp they can be simplified from the sums and we get that:

Finally, ∠QRP and ∠SRT are at opposite sides of the X shape formed by the intersection of lines QS and PT, they share a vertex at point R. These angles are vertically opposite angles and therefore congruent, so that:

You can conclude that ΔPQR and ΔTSR are congruent by the Angle-Side-Angle postulate.

Answer:

w = 4

w = -1/2

Step-by-step explanation:

so first of all this looks like a quadratic equation . I say this because you can subtract 4 to get 0 on one side . so you will have 2w²-2w-4=0.

to solve quadratic equations you need to use the quadratic formula . keep in mind you can only use the quadratic formula when your own quadratic equation is set set equal to 0. quadratic formula is equal to:

x= (-b±sqrt(b²-4ac))÷2a

now because this is a quadratic you can identify the values x, b, a, and c. we know that if it is a quadratic equation then the equation will be ax²+ BX + C. this is the basic formula for a quadratic equation so your values will be a equals 2 and B = -7 and C equals -4 and W equals X .

now because we know these values we can substitute it into the quadratic formula that i mentioned earlier .

x=(-(-7) ± sqrt( (-7)²-(4×2×(-4)) ) ) ÷ (2×2)

when you're simplify this you get

x= (7±sqrt(49+32))÷4

x= 7±sqrt(81) ÷ 4

x= (7±9)÷4

for quadratics it's normal that the x value is going to be two different values so don't panic at that !

the first x value

x= (7+9)÷4

= 16÷4

=4

the second x value

x= (7-9)÷4

=(-2)÷4

=-1/2

now remember that we said W equals X so the value of w will be 4 or -1/2 .

To find : What are the solutions of the compound inequality .

Solution : We have given 2d + 3 ≤ –11 or 3d – 9 > 15.

For  2d + 3 ≤ –11

On subtracting both sides by 3

2d  ≤ –11 - 3 .

2d  ≤ –14.

On dividing both sides by 2 .

d  ≤ –7.

For  3d – 9 > 15.

On adding both sides by 9.

3d > 15 + 9 .

3d > 24 .

On dividing both sides by 3 .

d > 8 .

So, A. d ≤ –7 or d > 8.

Therefore,  A. d ≤ –7 or d > 8.

What is probability ?

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

How is probability determined?

The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

SAS property, both triangles are similar.

The two triangles are congruent if we can demonstrate that two sides and the included angle of one triangle are congruent with two sides and the included angle of another triangle. The Side Angle Side Postulate, or SAS, is what this states. The triangles are congruent if two sides and the included angle of one triangle are equivalent to two sides and the included angle of another triangle. According to the SAS postulate, two sides and one angle (between the sides) of one triangle must be identical to two sides and one angle of another for two triangles to be considered congruent.

The indefinite integral of  ∫(2ti+j+8k)dt is  t²i +tj+8tk+c.

Given the expression is ∫(2ti+j+8k)dt

The indefinite integrals, also known as the derivatives of functions, are integrals that can be computed using the process of differentiation in reverse.

Further approaches for resolving indefinite integrals include integration by parts, substitution, integration of partial fractions, and integration of inverse trigonometric functions.

now, ∫(2ti+j+8k)dt

= 2t²/2 i + tj +8tk

= t²i +tj+8tk+c

Step-by-step explanation:

Comment

The idea behind this question is like flipping a coin and getting either heads or tails. The probability does not depend on a previous through if the coin is an honest coin.

So if you toss the coin 3 times, and you want to get all three tosses to be heads, there are 8 ways that you can throw 3 coins. Only 1 of the eight will give three heads, so the answer is 1/8.

This is the same kind of problem. He goes to work on 3 days, each day doesn't  depend on what happened on any other day.

Probability(3 days on time) = 0.1   *   0.1   * 0,1 = 0.001 or 1/1000
