Answer:

7.4

Step-by-step explanation:

solve for side a in first triangle:

$10^2-6^2=y^2$

100-36= $\sqrt{64}$ (take square root of 64)

y=8

then use 8 to solve for x:

$8^2-3^2=x^2$

64-9= $\sqrt{55}$ (take square root of 55)

x=7.4

2x+1.5y=30 in slope intercept form

Sauron [17]

Answer:

y = -4/3x + 20

Step-by-step explanation:

2x + 1.5y = 30

1.5y = 30 - 2x

y = 20 - 4/3x

y = -4/3x + 20

x^2 - x/5 + 2 = 0

Subtract 2 from both sides.

x^2 - x/5 = -2

Multiply all terms by 5.

5x^2 - x = -10

Add 10 to both sides.

5x^2 - x + 10 = 0

We can now apply the quadratic formula:

$-b ± \frac{\sqrt{b^2 - 4ac} }{2a}$

1 ± (√ 1 - 200) / 10

1 ± √-199 / 10

1 ± i√199 / 10

<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>

Ms. Green tells you that a right triangle has a hypotenuse of 12 and a leg of 5. She asks you to find the other leg of the trian

Anit [1.1K]

let the other leg be x cm.

(5)^2+(x)^2=(12)

25+(x)^2=144

(x)^2=144-25

x=√119

x=10.9
