The solution of equations is x=3 ,y=1

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given;

x=3y

2x+4y=10

Substitute the first equation into the second one

2(3y)+4y=10

6y+4y=10

10y=10

Y=1

Place the answer for Y into the first equation

X=3(1)

X=3

Therefore; the value of x and y of equations will be 3 and 1

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

Answer:

Step-by-step explanation:

we start out with 50 flyers, then a volunteer takes away 5. This puts us now at 45 flyers, then another volunteer takes 18 flyers, leaving us at 27. We now have to equally share the remaining flyers with 3 volunteers. To do this we do 27 divided by 3, which gives us 9. Meaning we give 9 flyers to each of the remaining 3

Answer:

= 222q^8 - 5m + 20n -37 + 21

Step-by-step explanation:

−5(m−4n−5)−37(p−6q8)−4

step 1  

=(−5)(m)+(−5)(−4n)+(−5)(−5)+(−37)(p)+(−37)(−6q8)+−4

=−5m+20n+25+−37p+222q8+−4

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.

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.

So,I can understand it

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

Necesario

24 / c

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.

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.

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.

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.

The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.

Answer:

thats the answer im pretty sure

but you cant see the first two question options

[tex]\color{plum}\tt \: \bold{(A) 12x - 4 = 10x + 10 ; x = 7}[/tex]

Since 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 :

[tex] = \tt12 \times 7 - 4[/tex]

[tex] = \tt84 - 4[/tex]

[tex] = \tt80[/tex]

Thus, ∠12x - 4 = 80°

[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

Yes.
