Answer:
y=3/4x-6
Step-by-step explanation:
u have to use the y2-y1/x2-x1 to fid the slope which is 3/4
then use slope intercept form which is y=mx+b to find if the equation has a y-intercept, plug in on point into the slope intercept form -12=3/4(-8)+b and u would get 6.

If the m∠1 =57°, Find the measure of ∠6
A- 123 °
B- 57 °
C- 180 °
D- Cannot be determined
Answer:
123
Step-by-step explanation:
[tex]180 - 57 = 123[/tex]
The solution is, the value of m∠6 is 123, i.e. A- 123 °.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
here, we have,
from the given figure we get,
angle 1 is equal to angle 5
as they are corresponding angles,
so, m∠1 =57° = m∠5
now, we have,
that the sum of 5 & 6 is 180
so, they are supplementary angles.
i.e. m∠6 = 180 - m∠5
=180 - 57
=123
Hence, The solution is, the value of m∠6 is 123, i.e. A- 123 °.

The Bernards are trying to determine their babysitter's rates but are to embarrassed to just ask her. They were charged $20 for 2 hours last week, but only $31 for 4 hours this week. What is the formula to determine A(Amount) given t(time in hours)?
Answer:
A = 5.5t + 9
Step-by-step explanation:
We assume that the relationship between t and A is linear.
We have two points on a line: (2, 20) and (4, 31).
We now find the equation of the line.
A = mt + b
m = (31 - 20)/(4 - 2) = 11/2 = 5.5
20 = 5.5(2) + b
20 = 11 + b
b = 9
A = 5.5t + 9

Maya claims that 8n is the number of dots in figure n. Kiana claims that the number of dots in figure n is given by 4(n+1)
Consider the square arrangements below in relation to the girls' expressions, where n represents the figure number.
Determine whether Maya, Kiana or both girls are correct in their given expressions. Justify your response.
The evaluation of your response will be based on the following criteria.
Answer:
Answer:
Kaya's answer is correct.
Step-by-step explanation:
The number of dots in successive figures are
8, 16, 24.
So Kaya's solution 8n is correct.
When n = 1, first square = 8*1 = 8 dots
n = 2: second square = 8*2 = 16
n = 3, 3rd square = 8*3 = 24.
If I have interpreted Kianna's formula correctly
for n = 1, then the number of dots = 2(1+ 1)^2 - 2(1 - - 1)^2

suppose you are buying two kinds of chips for a party. Each bag of potato chips cost $2.50 and each bag of corn chips cost $2.90. You must have at least 100 bags of chips for the party and the total cost of the chips can be no more than $350
Part A:Write a system of two inequalities that describe the situation
Part B: Write one possible solution to the problem in sentence form
Answer:
At least means ≥
No more than means ≤
Let x = number of bags of potato chips
Let y = the number of bags of corn chips
x+y≥100
2.50x+2.90y≤$350
Let's try x=80 and y=20 (We know that is equals 100 so it will work for the first equation
2.50(80)+2.90(20) = 258 which is ≤$350
Buy 80 bags of potato chips and 20 bags of corn chips is one possibility.

Tom es el gerente del departamento de delicatessen en una tienda de comestibles. Debe programar que los empleados trabajen en el departamento durante al menos 260 horas a la semana. Tom tiene un empleado a tiempo parcial que trabaja 20 horas a la semana. Cada empleado a tiempo completo trabaja 40 horas a la semana. Escriba una desigualdad para determinar nnn, el número de empleados a tiempo completo que Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana.
Answer:
La desigualdad para determinar el número de empleados a tiempo completo que Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana es 20+40*n ≥ 260. Resolviendo al menos 6 empleados deben trabajar a tiempo completo.
Step-by-step explanation:
Una inecuación es una desigualdad entre letras (incógnitas) y números relacionados por operaciones aritméticas. Su conjunto solución es el conjunto de números reales que la satisfacen. En una desigualdad, dos expresiones algebraicas están conectadas a través de los signos: mayor que >, menor que <, menor o igual que ≤ y mayor o igual que ≥.
Tom tiene un empleado a tiempo parcial que trabaja 20 horas a la semana. Cada empleado a tiempo completo trabaja 40 horas a la semana. Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana.
Sabiendo que x representa la cantidad de trabajadores a medio tiempo y n la cantidad de trabajadores a tiempo completo, entonces 20*x+40*n representa la cantidad de horas que todos los empleados trabajan semanalmente. Si los empleados trabajen al menos 260 horas a la semana, esto significa que la cantidad de horas que todos los empleados trabajan a la semana debe ser mayor o igual a 260 horas. Entonces:
20*x+40*n ≥ 260
Si Tom tiene un empleado a tiempo parcial, entonces la cantidad de trabajadores a medio tiempo x debe tener un valor de 1. Entonces:
20*1+40*n ≥ 260
20+40*n ≥ 260
40*n ≥ 260 -20
40*n ≥ 240
n ≥ 240 ÷40
n ≥ 6
Entonces 6 empleados o más deben trabajar a tiempo completo.

In the diagram, △ABC ~ △DEF. What is AC?
The image is of two similar right triangles ABC and DEF with right angles at B and E respectively. First one smaller in size and its base is 3. Base, altitude and hypotenuse of second one are 6, 8 and 10 respectively.
A. 4
B. 7.5
C. 5
D. 3
Answer:5
Step-by-step explanation: If you look at the base of both triangles, you'll notice that the smaller one has a base of 3, and the bigger one has a base of 6. The smaller triangle is half of the big one, therefore we can safely say that the hypothenuse of the smaller triangle is half of that of the larger one. Half of 10 is 5.

The amount of money left in Alma's bank account is expressed by the linear equation y = -27x + 577, where x represents the number of weeks and y represents the amount of money left in her account. After how many weeks will Alma have $145 left in her account? 12 weeks 16 weeks 22 weeks 26 weeks
Given:
The linear equation is
[tex]y=-27x+577[/tex]
where x represents the number of weeks and y represents the amount of money left in Alma's account.
To find:
The number of weeks in which Alma have $145 left in her account.
Solution:
We have,
[tex]y=-27x+577[/tex]
Substitute y=145, we get
[tex]145=-27x+577[/tex]
Subtract both sides by 577.
[tex]145-577=-27x[/tex]
[tex]-432=-27x[/tex]
Divide both sides by -27.
[tex]\dfrac{-432}{-27}=\dfrac{-27x}{-27}[/tex]
[tex]16=x[/tex]
So, the number of required weeks is 16. Therefore, the correct option is B.

The answer is 74.
I need to show my work.
THANK YOU!!!!!
Answer:
x = 74
Step-by-step explanation:
If you add all the angles in the diagram, you will get 360 degrees (since it's a complete revolution, and one revolution = 360 degrees).
Form an equation in x with this information:
4x+1+x-35+24 = 360
5x -10 = 360
5x = 370
x = 74

What is probability?"For any experiment, a probability denotes the possibility of outcome for any event."
The formula to calculate the probability of an event:For event A, the probability of event A is,
P(A) = number of favorable outcomes/ total umber of outcomes
What is conditional probability?"Conditional probability is the probability of an event occurring given that another event has already occurred."
The formula to calculate the conditional probability:P(A|B) = P(A∩B)÷P(B)
For given diagram:
Let A represents a set of students playing Basketball and B represents a set of students playing Soccer
So, A = {Fran, Ian, Juan, Ella}
⇒ n(A) = 4
B = {Mickey, Marcus, Ella}
⇒ n(B) = 3
(A ∩ B) = {Ella}
⇒ n(A ∩ B) = 1
sample space: S = {Fran, Ian, Juan, Ella, Mickey, Marcus, Mai, Karl, Jada, Gabby}
⇒ n(S) = 10
Now, we calculate probability of B and A∩B.
P(B) = n(B)/n(S)
⇒ P(B) = 3/10
Also, P(A∩B) = n(A∩B) / n(S)
⇒ P(A∩B) = 1/10
So, the required probability would be,
⇒ P(A|B) = P(A∩B) ÷ P(B)
⇒ P(A|B) = (1/10) ÷ (3/10)
⇒ P(A|B) = 1/3
Therefore, P(A|B) = 1/3

Michael uses lemonade concentrate and water to make lemonade for the family. The ratio of cups of lemonade
concentrate to cups of water is 1:3. If he made 32 cups of lemonade for the family, how many cups of
concentrate did he need?
Answer:
8 cupsStep-by-step explanation:
Given that the ratio is 1:3
concentrate =1
water=3
the total =3+1=4
using the part to all method
1/4=x/32
cross multiply
4x=32
divide both sides by 4 we have
x=32/4
x=8
