Answer:
x = [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
Given
2x + 5 = 12 ( subtract 5 from both sides )
2x = 7 ( divide both sides by 2 )
x = [tex]\frac{7}{2}[/tex] [ or x = 3.5 ]

cos(x+y) + cos(x-y) = 2cosx cosy
Answer:
Step-by-step explanation:
the given equation
cos(x+y)+cos(x-y)=2cos(x)*cos(y)
[cos(x)cos(y)-sin(x)sin(y)]+cos(x-y)=2cos(x)*cos(y) ..
[cos(x)cos(y)-sin(x)sin(y)]+[cos(x)cos(y)+sin(x)sin(y)]=2cos(x)*cos(y)
[cos(x)cos(y)+cos(x)cos(y)]]+[sin(x)sin(y)-sin(x)sin(y)]=2cos(x)*cos(y) ..
2cos(x)*cos(y)=2cos(x)*cos(y)

The graph shows a journey in a car. Which of the statements most likely describes the journey at the portion of the graph labeled J?
A line graph is drawn on the first quadrant of a coordinate plane. The x-axis is labeled Time in seconds, and the y-axis is labeled Distance in miles. The line graph is divided into 7 segments labeled I, J, K, L, M, N, and O. I starts at the origin and is a straight line slanting up. J is a line segment that starts at the end of I and is horizontal. K is a curve that starts at the end of J and curves up. L is a straight line that starts at the end of K and is horizontal. M is a straight line that starts at the end of L and slopes down. N is a straight line that starts at the end of M and is horizontal. O is a curve that starts at the end of N and curves down to finally touch the x-axis.
The car continues its journey because the portion shows a linear function.
The car is waiting at the starting point because the portion shows a constant function.
The car is traveling the same distance per unit of time because the portion shows a linear function away from the starting point.
The car stops at a distance away from the starting point because the portion shows a constant function away from the starting point.
Answer: Your answer my friend is D, The car stops a distance away from the starting point because the portion shows a constant function away from the starting point.
Step-by-step explanation:
The graph you have explained shows that at J it is a linear or horizonltal line. Whisch means the car is stopped for that period but it is not at the very beginning. Yw
Based on the information given regarding the graph, the correct option is D. The car stops at a distance away from the starting point because the portion shows a constant function away from the starting point.
Solving the graph.From the information given, it was stated that the graph shows a journey in a car and that the x-axis is labeled Time in seconds, and the y-axis is labeled distance in miles.
Therefore, the statement that most likely describes the journey at the portion of the graph labeled J is that the car stops at a distance away from the starting point because the portion shows a constant function away from the starting point.

Find the probability that x <-3
Answer:
Step-by-step explanation: if you want to obtain the probability that x [tex]\leq[/tex]-3 , then you need to add the probability for the cases x=-3 and x=-5.
p=0.13+0.17= 0.3
answer=0.3
The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
As per the given probability distribution.
The probability distribution is the probability of different cases.
In cases the probability adds thus,
P(x ≤ - 3) = P (x = -3) + P(x = -5)
⇒ 0.13 + 0.17 = 3
Hence "The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30".

9. A contestant on a game show must guess the price of a new car. The contestant will
win if his guess is within $1000 of the price of the car. If the price of the car is
$24,995 and the contestant's guess is represented by g, what absolute value
inequality represents this situation?
Given :
A contestant on a game show must guess the price of a new car. The contestant will win if his guess is within $1000 of the price of the car.
To Find :
If the price of the car is $24,995 and the contestant's guess is represented by g, what absolute value inequality represents this situation.
Solution :
Let, range in which participant guess would be considered correct is r.
So, r should be in range $( 24,995 ± 1000 ).
( 24,995 - 1000 ) ≤ r ≤ ( 24,995 + 1000 )
23,995 ≤ r ≤ 25,995
Therefore, the correct inequality is 23,995 ≤ r ≤ 25,995 .
Hence, this is the required solution.

Supplementary angles are the angle whose sum is 180° thus the angles which are supplementary to angle 7 are 8 and 6.
What is an angle?The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
The supplementary angle is two angles whose sum is 180°.
It is known that the sum of two angles on a straight line is 180°.
The angles 7 and 8 are on a straight line thus 7 + 8 = 180°.
So, they will be supplementary angles.
Angles 7 and 6 are in a straight line.
Thus, 7 + 6 = 180°.
Hence "Supplementary angles are the angle whose sum is 180° thus the angles which are supplementary to angle 7 are 8 and 6".

Out of 2,4,7,8,12,15,19,24,34 wich is not a multiple of 4
Answer:
2, 7, 15, 19, 34
Step-by-step explanation:
First, we have to know what a multiple is. A multiple is a number (n) that can be evenly divided by a certain base number (b). An evenly divided number is one that has no decimal points (ex: 1, 100, 24). For example, the multiples of 8 (b) would be 16, 24, 32, etc (n). Another example would be that 32 is a multiple of 2, 8, 16, etc. since it can be evenly divided by those numbers.
In this case, n = each of the numbers in that list, while b = 4. So now we just have to look at what numbers in our list can be evenly divided by 4.
2 is not a multiple since it cannot be evenly divided by 4, since it is less than 4.4 is a multiple of 4, since 4/4 = 1, and 1 is evenly divided.7 cannot be evenly divided by 4, and thus is not a multiple of 4.8 can be evenly divided by 4, since 8/4 = 2, and thus is a multiple of 4.12 can be evenly divided by 4, since 12/4 = 3, and thus is a multiple of 415 cannot be evenly divided by 4, and thus is not a multiple of 419 cannot be evenly divided by 4, and thus is not a multiple of 4.24 can be evenly divided by 4, since 24/4 = 6, and thus is a multiple of 4.34 cannot be evenly divided by 4, and thus is not a multiple of 4Since we're asked to find the numbers that are not multiples of 4, our answer to the question would be:

what is slope and y interceapt
Answer:
slope- 1
y-int- y=2x+-2
Step-by-step explanation:
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis). This useful form of the line equation is sensibly named the "slope-intercept form".
en una caja hay 8 canicas cinco rojas y tres verdes y la Bola que se retira no se reemplaza determina Cuál es la probabilidad de sacar dos bolas verdes
Answer: 0.107
Step-by-step explanation:
En una caja tenemos 8 canicas.
5 son rojas
3 son verdes.
Se retira una canica, y no se remplaza.
Quiero calcular la probabilidad de sacar dos canicas verdes.
La probabilidad de sacar una canica verde en el primer intento, es igual al cociente entre el numero de canicas verdes y el numero total de canicas.
p1 = 3/8
Ahora, en el segundo intento, en la caja voy a tener 2 canicas verdes (por que ya saque una) y 7 canicas en total. Entonces la probabilidad va a ser:
p2 = 2/7.
Y la probabilidad conjunta (es decir, la probabilidad de sacar las dos canicas de color verde) va a ser igual al producto de las probabilidades individuales.
P = p1*p2 = (3/8)*(2/7) = 0.107
Enter the value for x that makes the equation 4 + 2x – 8 + 8x = -54 true.

--------------------------------
We don't know the value of the number, so we call it x.The quotient of a number and negative five is:[tex]\frac{x}{-5} = -\frac{x}{5}[/tex]
One less than the quotient is:[tex]1 - (-\frac{x}{5}) = 1 + \frac{x}{5}[/tex]
--------------------------------
Supposing this is equals to 5.[tex]1 + \frac{x}{5} = 5[/tex]
[tex]\frac{x}{5} = 4[/tex]
[tex]x = 5 \times 4 = 20[/tex]
Thus, the number is 20.
