Answer:
Angle A
Step-by-step explanation:
subtract 3x and 5x
you get 2x
-5-3=
you get -8
divide -8/2x
x=-4
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Sum of the measures is equal to 180° .
So :
[tex]Angle \: \: A + Angle \: \: B + Angle \: \: C = 180 \\ [/tex]
Thus :
[tex](5x - 5) + (3 x + 3) + (5x) = 180 \\ [/tex]
Collect like terms
[tex]13x - 2 = 180[/tex]
Add sides 2
[tex]13x - 2 + 2 = 180 + 2[/tex]
[tex]13x = 182[/tex]
Divide sides by 13
[tex] \frac{13x}{13} = \frac{182}{13} \\ [/tex]
[tex]x = 14[/tex]
_________________________________
[tex]Angle \: \: B = 3x + 3[/tex]
[tex]Angle \: \: B = 3(14) + 3[/tex]
[tex]Angle \: \: B = 42 + 3[/tex]
[tex] Angle \: \: B = 45°[/tex]

Which inequality represents all the solutions of -5x + 5 ≥ 160 − 10x? A. x ≤ -33 B. x ≥ 33 C. x ≥ 31 D. x ≤ 31
Answer:
The answer is B.
Step-by-step explanation:
Solve for x.
-5x + 5 [tex]\geq[/tex] 160 - 10x
Add 10x to both sides, and subtract 5 from both sides.
5x [tex]\geq[/tex] 155
Now, divide by 5.
x [tex]\geq[/tex] 31 is the answer
#teamtrees #WAP (Water And Plant)
The inequality represents all the solutions x ≥ 31. Then the correct option is C.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given as,
−5x + 5 ≥ 160 − 10x
Simplify the equation, we have
10x – 5x ≥ 160 – 5
5x ≥ 155
x ≥ 31
Then the correct option is C.

What is the slope of the line that contains these points?
x 9 13 17 21
y -24 -21 -18 -15
Answer: m=3/4
Step-by-step explanation:
Looking at the table given, we can assume two of the points are (9,-24) and (13,-21). To find the slope with given points, we use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. We can plug the two points in and solve.
[tex]m=\frac{-21-(-24)}{13-9} =\frac{3}{4}[/tex]
Now, we know that the slope is 3/4.
Answer:
slope = 3/4

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

Answer:
Benett
Step-by-step explanation:
Answer: Betty
Step-by-step explanation:
Bennet isn't correct because we can plug in 300 for r. It will become 300= 50t, and solving for t, we get that it would take 6 minutes.
Betty is correct because we can change the variables r and t to y and x respectively. In this case, 50 would be the constant of proportionality, or k.
The distance of a golf ball from the hole can be represented by the right side of a parabola with vertex (−1, 8). The ball reaches the hole 1 second after it is hit, at time 0. What is the equation of the parabola, in vertex form, that represents the ball's distance from the hole, y, at time x
Answer:
The required equation is:
[tex]y = -\frac{4}{3}t^2 -\frac{8}{3}t + 4[/tex]
Explanation:
Let us assume that the hole is at y = 0m, with x as the time.
From the question we have (-1s, 8m) as the vertex (here x being the time variable is supposed to be in seconds and y being the distance variable is supposed to be in meters)
At x = 1s, the ball gets to the hole, therefore we have point (1s, 0m)
We know that the vertex of the parabola y = ax² + bx + c is at
[tex]x =\frac{-b}{2a}[/tex]
therefore we have:
[tex]-1 = \frac{-b}{2a}[/tex]
We then have the following equations:
[tex]8 = a\times -1^2 + b\times -1 + c[/tex]
[tex]0 = a\times -1^2 + b\times 1 + c[/tex]
[tex]-1 = \frac{-b}{2a}[/tex]
From the 3rd equation we have
1 X 2a = b.
Therefore we have:
[tex]8 = a\times -1^2 - 1\times 2a\times1 + c[/tex]
[tex]0 = a\times 1^2 + 1 \times2a\times 1 + c[/tex]
We can simplify both equations and get:
[tex]8 = a\times( -1^2 - 2s^2) + c = -a\times 3^2 + c[/tex]
[tex]0 = a\times(1^2 + 2^2) + c = a\times 3^2 + c[/tex]
The first equation now becomes:
[tex]8 = -a\times 3 - a\times 3 = -a\times 6[/tex]
[tex]a = frac{8}{-6} = -\frac{4}{3}[/tex]
With a, we can find the values of c and b.
[tex]c = -a\times3 = -(-\frac{4}{3})*3 = 4 [/tex]
[tex]b = 1\times 2a = 1\times 2(-\frac{4}{3})= -\frac{8}{3}[/tex]
Then the equation is:
[tex]y = -\frac{4}{3}t^2 -\frac{8}{3}t + 4[/tex]
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.

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.
4 more than the quotient 12 and a number x

What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given statement is,
4 more than the quotient 12 and a number x
Now, converting the statement into numerical form.
Since more than is addition.
Thus, 4 more than = 4 +
and, quotient 12 and a number x = 12/x
Thus, 4 more than the quotient 12 and a number x = 4 + 12/x
this is the required expression.

Write the equation of a line that is parallel to the graph of y = − 7x − 9, and passing through the point (1, 10). SHOW ALL WORK!
Answer:
y = - 7x + 17
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 7x - 9 ← is in slope- intercept form
with slope m = - 7
Parallel lines have equal slopes, thus
y = - 7x + c ← is the partial equation
To find c substitute (1, 10) into the partial equation
10 = - 7 + c ⇒ c = 10 + 7 = 17
y = - 7x + 17 ← equation of parallel line
