Answer:

Step-by-step explanation:

the funny lines in the corners of the triangle mean that the angles are the same. Maybe you knew that?

The supplementary angle at the top right is just

180- 17x -23

now you have expressions for each of the 3 angles of the triangle which all add up to 180°

180= 7x + 2 + 7x +2 + 180- (17x -23)

180 = 14x +4 + 180 - 17x +23

180 = -3x +207

3x = 27

x = 9

Answer:

Step-by-step explanation:

symmetry with respect to y-axis for y=f(x) means f(-x)=f(x)

in this case, y = f(x) = x / (x^2+4)

f(-x) = -x / ((-x)^2+4) = -x / (x^2+4) = -f(x)

so it is not symmetric to y-axis

symmetry with respect to x-axis for x=g(y) means g(-y)=g(y)

in this case, y = x / (x^2+4)

y*(x^2+4) = x

y*x^2 + 4y - x = 0

substitute -y into g(y)

(-y)*x^2 +4(-y) - x = 0

-y*x^2 - 4y - x = 0

y*x^2 + 4y + x = 0

so g(-y) is not equal to g(y)

so it is not symmetric to x-axis

Use the following compound interest formula to complete the problem currently you have two credit cards H and die card H has a b

abruzzese [7]

Answer:

card I by $82.50

Step-by-step explanation:

As you know the compound interest formula is ...

A = P(1 +r/n)^(nt)

For card H, P=1186.44, r=0.1474, n=1, t=3, so the balance will be ...

A = $1186.44(1.1474^3) ≈ $1792.22

For card I, P=1522.16, r=0.125, n=12, t=3, so the balance will be ...

A = $1522.16(1 +.125/12)^(12·3) ≈ $2210.44

The increase in card H is ...

$1792.22 -1185.44 = $605.78

The increase in card I is ...

$2210.44 -1522.16 = $688.28 . . . . . . card I increased more

The difference in the increases is ...

$688.28 -605.78 = $82.50

Card I increased by $82.50 more than card H in the time period.
