What is the solution to the system? x + y = 4 x+y=1

Answers

Given :

x + y = 4x + y = 1

To Find :

The value of x and y.

Answer :

x + y = 4 ....[Equation (i)]x + y = 1......[Equation (ii)]

Adding eqⁿ (ii) and eqⁿ (i) we get :

→ x + y + x - y = 4 + 1

→ 2x = 5

→ x = 5/2

→ x = 2.5

Now, put the value of x = 5/2 in eqⁿ (i) we get :

→ x + y = 4

→ 5/2 + y = 4

→ y = 4 - 5/2

→ y = 1.5

PLS HELP!!! due to inflation nominal prices are usually there were to demand increases. After the second increase the price for a certain item was twice as big as the original. By what percent was the first increase, if the second increase was 25%

Answers

Answer:

The first increase was of 60%.

Step-by-step explanation:

The initial value of the product is x.

The first increase was of y.

The second increase is of 25%, that is, 1.25.

The final price was double the original, so 2x.

This situation can be modeled by the following equation:

[tex]xy(1.25) = 2x[/tex]

We want to find y.

Simplifying by x

[tex]1.25y = 2[/tex]

[tex]y = \frac{2}{1.25}[/tex]

[tex]y = 1.6[/tex]

After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

Find the equation of the line with m = 2 and goes through (-4,5).PLEASE HELP

Answers

The Equation is y=+5
Why:

You want to find the equation for a line that passes through the point (-4,5) and has a slope of .
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was . So you can right away fill in the equation for a line somewhat to read:
y=x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,5). When x of the line is -4, y of the line must be 5.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 0 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,5).
So, why not plug in for x the number -4 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,5). y=mx+b or 5=0 × -4+b, or solving for b: b=5-(0)(-4). b=5.

Answer:

Step-by-step explanation:

The two triangles are congruent because if each triangle's angles add up 180 degrees, you can deduce that the triangles have atleast two congruent angles.

Triangle RST:

48 + 73 = 121

180 - 121 = 59

Angle R = 59

Angle T = 48

Angle S = 73

59 + 48 + 73 = 180

Triangle ABC:

73 + 59 = 132

180 - 132 = 48

Angle A = 59

Angle B = 73

Angle C = 48

59 + 48 + 73 = 180

the correct answer would be A

Monica had a savings account that paid her an interest rate of 4%. After she had this account for 12 years, she had received $192 in interest. How much money had she put into the account at the beginning of the 12 years?

Answers

Answer:

Money she put in her account = $400

Step-by-step explanation:

As, to find the interest the formula is PTR/100 = I

Where P = Principcal

And T = time (in years)

And R = rate

And I = interest

So here p is not present we need to find it

R = 4%

And T = 12 years

And I = $192

= p x 4 x 12 /100 = 192

P x 4 x 12 = 19200

P x 48 = 19200

P = 19200/48

P = 400

So Principcal = $400

A store has clearance items that have been marked down by 60%. They are having a sale, advertising an additional 45% off clearance items. What percent of the original price do you end up paying

Answers

Answer:

You end up paying 22% of the original price.

Step-by-step explanation:

The statement indicates that a store has clearance items that have been marked down by 60% and this means that you have to pay 40% of the price as:

100%-60%=40%

Now, the statement says that the are advertising an additional 45% off clearance items which means that you will have a 45% discount on the 40% of the original price. So, you have to calculate 45% of 40 and subtract that from 40 to find the percentage that you will end up paying:

40*45%=18

40-18=22

According to this, the answer is that you end up paying 22% of the original price.

The distance between two points P(a, b)a nd Q(c, d) is

D = √(c- a)² + (d- b)²

Given:

Center at (-2,7) if a point on the circle has coordinates (3,-1).

Using Distance Formula

D = √( 3-(-2))² + (1-7)²

D = √ (3 +2)² + (-6)²

D = √5² + 36

D = √25+36

D = √61

D= 7.81 unit
