Answer:

x=3

y=1

Step-by-step explanation:

We know that y is basically two less than x, so we can plug that into the second equation:

x+ (x-2) = 4

We can now simplify:

2x-2=4

2x=6

x=3

After finding x we can now find y with any equation (both work):

y= 3-2

y=1

Hope this helped!

Answer:

$y = -2x + 6$

Step-by-step explanation:

Given

$(x_1,y_1) = (1,4)$

$(x_2,y_2) = (2,2)$

Required

Determine the line equation

First, we calculate the slope (m) using

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{2-4}{2-1}\\$

$m = \frac{-2}{1}$

$m = -2$

The equation is then calculated using:

$y - y_1 = m(x - x_1)$

$y - 4 = -2(x - 1)$

Open bracket

$y - 4 = -2x + 2$

$y = -2x + 2 + 4$

$y = -2x + 6$

cost = 1.03 (1500) = 1545

put 1545 in for x in year 2

year 2

1.03 * 1545 = 1591.35

put in 1591.35 in for x in year 3

year 3

1.03 *1591.35=1639.0905

Your friend tells you that if you let her keep 2020 of your Pokemon cards for three months, she will give you 22 cards extra whe

Dmitrij [34]

Answer: 40 %

Step-by-step explanation:

Let the amount of one card = x

Hence, the value of 20 cards ( Principal amount ) = 20x

And, the value of 22 cards ( Total amount after 3 month ) = 22x

⇒ Total interest in 3 month = 22x - 20x =2x

Let the annual interest rate = r %

$\frac{20x\times r\times 3/12}{100}=2 x$ ( By the formula of simple interest rate )

$\implies \frac{10\times r\times 1/4}{100}=1$

$\implies \frac{10r}{400}=1$

$\implies 10r=400$

$\implies r=40\%$

Hence, the annual rate of interest = 40%

Can you give me the work and the answers for these please.

n200080 [17]

1. The diagonal is the hypotenuse so,
√[12² + 12²] = 16.97

2. The same process is done
51.96

3. Again, use the Pythagorean theorem
35.78

4. The perimeter is 44, so the length of a side is 11, the diagonal is
15.57

5. The diagonal is 20, the formula is
d =s√2
where d is the diagonal and s is the side
s = 14.14
