For the function f(x) = 2x + 9, find the value of x when f(x) = 15.

Answers

Answer 1
X = 3


subtract 9 from both sides, which leaves ur equation to 6 = 2x, which then you divide both sides by 2, leaving you with 3 as your answer !

A jar contains 8 red counters and 21 blue counters. A counter is taken at random from the jar. what is the probity that it is.
A. red
B. blue
C. green

Answers

A. 8/29
B. 21/29
C. 0/29

Since there are no green counters, the probability of selecting a green counter is always 0 in this context.

Given that the jar contains 8 red counters and 21 blue counters, we can determine the probabilities of selecting each color.

Total number of counters in the jar = 8 (red) + 21 (blue) = 29

(a) The probability of selecting a red counter:

Number of red counters / Total number of counters = 8 / 29

(b) The probability of selecting a blue counter:

Number of blue counters / Total number of counters = 21 / 29

(c) The probability of selecting a green counter:

There are no green counters in the jar, so the probability of selecting a green counter is 0.

Therefore, the probabilities are as follows:

A. The probability of selecting a red counter is 8/29.

B. The probability of selecting a blue counter is 21/29.

C. The probability of selecting a green counter is 0.

Please note that since there are no green counters, the probability of selecting a green counter is always 0 in this context.

Could someone give me a hand?

Answers

Answer:

Step-by-step explanation:

Look at the image I attached for reference as I explain. (I only labeled the angles that are relevant to the problem)

These triangles are congruent, as shown by the first equation.

When triangles are congruent, it means that the sides and angles are the same.

We can see that angles ∠ABC and ∠DEC are corresponding, which means that they have the same value.

We don't know ∠DEC, but we have two angles in that triangle that we do know. Since the angles in a triangle add up to 180, we have this equation:

180-65-55=∠DEC

60 = ∠DEC

So now we know that ∠DEC is 60 degrees.

Since ∠ABC and ∠DEC are equal:

2x=60.

Divide both sides by 2, and we get x =30.

Of the marbles in a​ bag, 5 are blue​, 2 are white​, and 2 are yellow. Sandra will randomly choose one marble from the bag.

Answers

Answer:

[tex]\dfrac{2}{9}[/tex]

Step-by-step explanation:

Given that,

A bag contains 5 blue, 2 white and 2 yellow marbles.

We need to find the probability of choosing a white marble from the bag.

Total no. of outcomes = 5+2+2

= 9

No. of white marbles = 2

Required probability,

[tex]P=\dfrac{2}{9}[/tex]

So, the probability of choosing a white marble is equal to [tex]\dfrac{2}{9}[/tex].

The line of best fit is:

y = 3.1x + 12.9

Option A is the correct answer.

We have,

The line of best fit can be expressed in the form of y = ax + b,

where a is the slope of the line and b is the y-intercept.

From the given LinReg results, we have:

a = 3.1

b = 12.9

Substituting a and b in the equation y = ax + b we get,

The line of best fit is:

y = 3.1x + 12.9

Thus,

The line of best fit is:

y = 3.1x + 12.9

A triangle has angle measures of 47 degrees and 92 degrees. What is the measure of the third angle?

Answers

Answer:

The missing angle is 41 degrees

Step-by-step explanation:

First of all, a triangle is measured at 180 degrees in total

To find the missing measurement for the third angle, add the 47 and 92 degrees together which would equal 139 degrees.

47+92=139 degrees

Next just subtract 139 from 180 to get your answer.

180-139=41 degrees

The answer is 41 degrees

Question 2 options:

Answers

Answer:

Question 2 = True

I don't know the first question, the test wouldn't tell me:/

Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35 and the statement that Sin B is greater than Sin Y is false.

What is a similar triangle?

The two triangles are said to be similar that have the same proportion of sides and angles.

Corresponding sides are in the same ratio.

a/p = b/q = c/r

In triangle ABC

AB = 5, AC = 3, BC = 4

Cos A = base/ hypotenuse

          = 3/5

Cos B = base/ hypotenuse

          = 4/5

Cos C = base/ hypotenuse

          = 3/5

In triangle WYZ

Cos W = base/ hypotenuse

           =  3/5

Cos Z = base/ hypotenuse

          = 4/5

Hence, Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35.

In triangle WYZ

WY = 13

In triangle ABC

CB = 24, AC = 10

Sin B = Perpendicular/ hypotenuse

         = 10/26

Sin Y = Perpendicular/ hypotenuse

        = 5/13

Since both angles are equal also they are similar to each other.

Therefore, the statement that Sin B is greater than Sin Y is false.

Jennifer writes the letters M-O-N-T-A-N-A on cards and then places the cards in a hat. What is

Answers

Given:

Jennifer writes the letters M-O-N-T-A-N-A on cards.

To find:

The probability of picking an N.

Solution:

We have,

Total number of cards = 7

Total number of cards with letter N = 2

Now, the probability of picking an N is:

[tex]\text{Probability}=\dfrac{\text{Number of cards with letter N}}{\text{Total number of cards}}[/tex]

[tex]\text{Probability}=\dfrac{2}{7}[/tex]

Therefore, the probability of picking an N is [tex]\dfrac{2}{7}[/tex].
