Answer:
Step-by-step explanation:
-x + 10 = 40
-x = 40 - 10
-x = 30
x = - 30
-3x + 4 = 10
-3x = 10 - 4
-3x = 6
x = 6/-3
x = - 2
Answer:
x=-30 for A
Step-by-step explanation
subtract both sides by 10 which means 40-10=30
then add the negative sign

The Ministry of Misallocation has decreed that the production of widgets must be 4000 each month and the production of gizmos must be 10000 each month. Calculate the deadweight loss in each market caused by these restrictions. Please note the scale of the quantity axis is in thousands.What is the deadweight loss in the gizmos market
Answers
Kindly find attached graph below :
Answer:
10,000
Step-by-step explanation:
Given that :
Decreed production level by the ministry :
Monthly widget production = 4000
Monthly gizmos production = 10,000
Deadweight loss for gizmos :
0.5(p2 - p1) * (Q2 - Q1)
0.5(70 - 60) * (10000 - 8000)
0.5 * 10 * 2000
10,000
Hence, Deadweight loss on gizmos is 10000
Deadweight loss occurs when equilibrium output is not attained.

If a store raises a coffee mug's price from $6.25 to $8.77. The price increase was 40.32%. Option C is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that, A retailer marks up the price of a coffee mug from $6.25 to $8.77.
We have to find the percentage by which the price increase,
% increment = New rate - old rate / old rate × 100
% increment =(8.77 - 6.25)× 100
% increment =40.32%
Thus, if a store raises a coffee mug's price from $6.25 to $8.77. The price increase was 40.32%. Option C is correct.

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of 0.891 is calculated. What would this imply about the football team winning at home?
The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, but causation cannot be determined.
The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, and a causal relationship exists between the team playing at home and winning.
The scatter plot would not be represented by a line of best fit with a positive slope. There is a weak correlation between the football team playing at home and winning.
There is no causation and almost no correlation between the football team playing at home and winning.
Answers
Answer:
The scatter plot would closely resemble a straight line with a positive slope, but causation cannot be determined.
Step-by-step explanation:
Recall that causation and correlation are 2 different things. Say Taller people usually had a name that started with the letter “A” It's a correlation, but a name does not determine the height, so it's not causation. (I took the test and got it right too.)
The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning would be imply about the football team winning at home.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
It also is the slope of the line of best fit.

Responder:
a) 2
b) 5
c) 4
d) 3
Explicación paso a paso:
Debemos encontrar el MCD de los siguientes números
a) 54, 76, 114
encontrar los factores primos de cada
54 = 2 * 3 * 3 * 3
76 = 2 * 2 * 19
114 = 2 * 2 * 2 * 2 * 3 * 3
De los factores anteriores, podemos ver que solo 2 es común a todos los factores, por lo tanto, el MCD de 54, 76 y 114 es 2
b) Para 35, 50 y 120
35 = 5 * 7
50 = 2 * 5 * 5
120 = 2 * 2 * 2 * 3 * 5
De los factores anteriores, podemos ver que solo 5 es común a todos los factores, por lo tanto, el MCD de 35, 50 y 120 es 5
c) Para 12, 16 y 20
12 = 2 * 2 * 3
16 = 2 * 2 * 2 * 2
20 = 2 * 2 * 5
De los factores anteriores, (2 * 2) es común a todos ellos, por lo tanto, el MCD de 12, 16 y 20 es 4
d) Para 56 y 120
56 = 2 * 2 * 2 * 7 = 8 * 7
120 = 2 * 2 * 2 * 3 * 5 = 8 * 3 * 5
De los factores anteriores, podemos ver que solo 8 es común a todos los factores, por lo tanto, el MCD de 56 y 120 es 8.
Por tanto, c = 8

Consider that lines u and vare parallel. Which equation models the relationship between the angles? What is the value of x?
Answers
[tex]\color{plum}\tt \: \bold{(A) 12x - 4 = 10x + 10 ; x = 7}[/tex]
Steps to derive the correct option :Given :Lines u and v are parallel Measure of an angle = 12x - 4Measure of it's corresponding angle = 10x + 10Since these angles are corresponding angles and lie on two parallel lines, their value will be equal.
Which means :
[tex] = \tt12x - 4 = 10x + 10[/tex]
[tex] = \tt12x - 4 - 10x = 10[/tex]
[tex] = \tt12x - 10x = 10 + 4[/tex]
[tex] = \tt2x = 14[/tex]
[tex] =\tt x = \frac{14}{2} [/tex]
[tex] =\color{plum}\tt x = 7[/tex]
Thus, the value of x = 7.
Let's place 7 in the place of x and see if their value matches :
12x - 4[tex] = \tt12 \times 7 - 4[/tex]
[tex] = \tt84 - 4[/tex]
[tex] = \tt80[/tex]
Thus, ∠12x - 4 = 80°
10x + 10[tex] =\tt 7 \times 10 + 7[/tex]
[tex] = \tt70 + 10[/tex]
[tex] = \tt80[/tex]
Thus, ∠10x + 10 = 80°
Since the value of these two angles are equal, we can conclude that we have found out the correct measure of each angle.
Therefore, the correct option is - (A) 12x - 4 = 10x + 10; x = 7

Write the equation of the line that goes through the point (-2,3) and has a slope of -4
Answers
Answer:
y=-4x-5
Step-by-step explanation:
Use the equation of the line formula, y=mx+b
since we know that the slope is -4, we just have to find b
plug the points into the equation, y=-4x+b
(3)=-4(-2)+b
simplify
3=8+b
subtract 8 from both sides
b=-5
plug b into the equation
y=-4x-5
