2x = -y + 2 Complete the ordered pairs

Mathematics
1 answer:
Nady [450]4 years ago
5 0

Answer:

Examples of ordered pairs that will complete the equation:

(0, 2)

(1, 0)

(2, -2)

(3, -4)

Step-by-step explanation:

Choose an number and insert for x, then solve for y. For example:

if x=0 then:

2(0) = -y + 2

0 = -y + 2

-2 = -y

2= y

Therefore, when x = 0, y = 2.

CONDITIONAL PROBABILITY ASSISTANCE
Mars2501 [29]

Consider such events:

A - selected student is freshmen

B - selected student is girl

A\cap B - selected student is freshman is girl

A|B - choosen girl is freshmen.

Use formula Pr(A|B)=\dfrac{Pr(A\cap B)}{Pr(B)}.

From the table you can see that girls that are freshmen are 4 from all 30 people, then Pr(A\cap B)=\dfrac{4}{30}. There are 18 girls, then Pr(B)=\dfrac{18}{30}. Substitute into the formula:

Pr(A|B)=\dfrac{\frac{4}{30} }{\frac{18}{30} }=\dfrac{4}{18} =\dfrac{2}{9}.

Answer: Pr(A|B)=\dfrac{2}{9}.

Marina86 [1]

Answer:

10

Step-by-step explanation:

you use the Pythagorean theorem which you do 24^2 + b^2 = 26^2 you should have 576+b^2=676 then subtract 576 on both sides b^2=100 then sqre root which leaves you with b=10

Solve the following logarithmic equations.<br> ln(x^6) = 36
Hoochie [10]

Answer:

The solution is x = e⁶

Step-by-step explanation:

Hi there!

First, let´s write the equation

ln(x⁶) = 36

Apply logarithm property: ln(xᵃ) = a ln(x)

6 ln(x) = 36

Divide both sides of the equation by 6

ln(x) = 6

Apply e to both sides

e^(ln(x)) = e⁶

x = e⁶

The solution is x = e⁶

Let´s prove why e^(ln(x)) = x

Let´s consider this function:

y = e^(ln(x))

Apply ln to both sides of the equation

ln(y) = ln(e^(ln(x)))

Apply logarithm property: ln(xᵃ) = a ln(x)

ln(y) = ln(x) · ln(e)         (ln(e) = 1)

ln(y) = ln(x)

Apply logarithm equality rule: if ln(a) = ln(b) then, a = b

y = x

Since y = e^(ln(x)), then x =e^(ln(x))

Have a nice day!
