Answer: (4,-5)

Step-by-step explanation:

8y = -40

(divide by 8)

y = -5

(plug it in to one of the equations)

3x + 6*-5 = -18

3x + -30 = -18

3x = 12

x = 4

Answer:

Look at the proof down

Step-by-step explanation:

The given is;

→ ∠1 and ∠2 form a linear pair

→ ∠1 ≅ ∠3

We want to prove;

→ ∠2 and ∠3 are supplementary

We will write the proof in like a table

1. ∠1 and ∠2 formed a linear pair  ⇒  1. Given

2. m∠1 + m∠2 = 180°  ⇒ 2. Sum of angles on a straight line

3. ∠1 and ∠2 are supplementary angles  ⇒  3. Supplementary angles add up to 180°

4. ∠1 ≅ ∠3  ⇒  4. Given

5. m∠2 + m∠3 = 180°  ⇒  5. Substitution method

6. ∠3 is a supplement of ∠2  ⇒  6. Supplement of equal angles

7. ∠2 and ∠3 are supplementary  ⇒  7. Proved

Answer:

1 over 9

Step-by-step explanation:

Answer:

The correct answer is A.) 1/9

Step-by-step explanation:

Answer:

y = 2(x - 9)² - 1

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k ) = (9, - 1 ) , thus

y = a(x - 9)² - 1

To find a substitute (7, 7 ) into the equation

7 = a(7 - 9)² - 1 ( add 1 to both sides )

8 = 4a ( divide both sides by 4 )

2 = a , then

y = 2(x - 9)² - 1

Answer:

the answer is 35.

Step-by-step explanation:

So first you look for 75 on the x-axis because this represents the number of people in attendance. 75 would be the line between 50 and 100. Then you need to follow the 75 line up until you see the point that the graphed line intersects the "75 line". When you drag you finger from that point over to the y-axis, you see the number of recyclables is about 35.

Answer:

5.20.10

Step-by-step explanation:

Answer:

Maximum returns = $1,980,000

x = Homeowner loans = $17,600,000

y = Auto loans = $4,400,000

Madison should extend $17,600,000 in home owners loans and $4,400,000 in auto loans in order to have a maximum return of $1,980,000

Step-by-step explanation:

From the question we are told that:

Madison Finance has a total of $22 million earmarked for homeowner loans and auto loans, where x is homeowner loans in millions of dollars and y is auto loans in millions of dollars.

On the average, homeowner loans have a 8% annual rate of return, whereas auto loans yield a 13% annual rate of return.

We have the equation:

Maximum Return = 8% × x + 13% × y

= 0.08x + 0.13y

We are told in the question that

Management has also stipulated that the total amount of homeowner loans should be greater than or equal to 4 times the total amount of automobile loans.

Hence,

x ≥ 4y

So:

x + y = $22,000,000

4y + y = $22,000,000

5y = $22,000,000

y = $22,000,000/5

y = 4,400,000

x = 4y

x = 4(4,400,000)

x = 17,600,000

Maximum Return = 0.08x + 0.13y

= 0.08 × 17,600,000 + 0.13 × 4,400,000

= $1,980,000

Therefore, Madison should extend $17,600,000 in home owners loans and $4,400,000 in auto loans in order to have a maximum return of $1,980,000

Answer:

"2.660503478" would be the right answers to the key statement.

Step-by-step explanation:

Drawing 5 balls out of 69 can be done in ([tex]\frac{69}{5}[/tex])

=  [tex]\frac{69\times 68\times 67\times 66\times 65}{5!}[/tex]

Drawing 1 ball out of 26 red balls can be done in ([tex]\frac{26}{1}[/tex])

= [tex]26[/tex]

Then the chance of drawing 5 out of 69 balls including 1 out of 26 red balls and then both matching the jackpot  

= [tex]\frac{1}{11238513\times 26}[/tex]

= [tex]\frac{1}{292201338}[/tex]

Since the sum of the jackpot is $193-106 and then one ticket costs $2, the estimated value of buying one ticket again for jackpot is $2.

= [tex]\frac{1}{292201338}\times 193\times 10^6+\frac{292201338-1}{292201338}\times 2[/tex]

Answer:

x < 50

Step-by-step explanation:

No more means that it cannot equal 50. Therefore we can remove the 1st two options.

We now have the 3rd option and 4th option to choose from.

The 4th option is incorrect because the inequality is saying that a number is greater than 50.

∴ x < 50 is our answer.
