The image doesn't make sense. The triangle is isosceles but yet 13=18. Could you help me verify which sides 13 and 18 are?

A squared plus b squared equals c squared is the formula or equation that is used regarding pythagorean theorem. The two opposite sides are a and b in that picture. Since one side is 18 and it is equal to the other line(hence the dashes), the other line is 18. Let’s plug this into the equation:

(18^2) + (18^2) =c^2
324 +324 = c^2
648=c^2
Now you have to find the square root of 648. The square root of 648 is 18√2.
C is equal to 18√2.

The function f(x) varies inversely with x and f(x)=0.5 when x = 0.3. What is f(x) when x = 2.4? A)5.76 B)0.0625 C)0.30 D)0.15

Answer:

B) 0.0625

Step-by-step explanation:

f(x) = k / x

f(x)=0.5 when x = 0.3

f(x) = k / x

0.5 = k / 0.3

Cross product

0.5 * 0.3 = k

k = 0.15

What is f(x) when x = 2.4?

f(x) = k / x

f(x) = 0.15 / 2.4

f(x) = 0.0625

The answer is B) 0.0625

Given the equation 4x + 7 = 3(2x − 5), solve for the variable. Explain each step and justify your process.

MariettaO [177]

Part 1: $4x + 7 = 3(2x - 5)$

$4x+7=6x-15$

$7=6x-15-4x

$

$7=2x-15$

$7+15=2x$

$22=2x$

$22=2x / 2$

$x=11$

Part 2: Sam is not correct because he messed up the second step. He added 2x on both sides to get 7x, instead he should have subtracted.

Which of the following sets is NOT closed under addition.

Veronika [31]

Answer:

Step-by-step explanation:

The odd numbers.

Suppose you have 31 and 27 when you add these two together, you get 58 which is not an odd number.

If you need a more mathematical proof, you could do it this way.

2x+1

2x is even. Anything multiplied by 2 is even. When you add 1 you get an odd number

So continue on

2y + 1 is the other number.

2x + 1 + 2y + 1 = 2(x + y) + 2

2 (x + y ) is even. When you add 2 to it, nothing changes. The result is still even.
