A variable needs to be eliminated to solve the system of equations below. Choose the correct first step. 9x – 2y = – 75 2x – 2y = -12 Add to eliminate x. Add to eliminate y. Subtract to eliminate y. Subtract to eliminate x. Submit Answer​

Answers

Answer 1

Answer:

pretty sure the answer is "add to eliminate y"

Step-by-step explanation:

since each side is a -2y you do the opposite which is adding :)

hope this helped! Good luck!

Answer 2

The value of x after eliminating the variable y is -9.

What is an elimination method?

The elimination method involves taking one variable out of the system of linear equations by using addition or subtraction along with multiplication or division of the variable coefficients.

Given that the two equations are 9x – 2y = – 75  and 2x – 2y = -12. The equations will be solved as,

9x – 2y = – 75  

2x – 2y = -12

The value of x will be calculated by elimination of the variable y,

9x – 2y = – 75  

-2x + 2y =+12

_____________

7x + 0 = -63

x = -9

Therefore, the value of x after eliminating the variable y is -9.

Using Transitive Property, it is found that b + 3 is equal to 12.

What is Transitive Property ?

The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.

Given;

If a +5 = b + 3 and a + 5 = 12, then we need to find b +3=

So, a + 5 = 12

and a +5 = b + 3

Then b + 3 is also equal to 12. (Transitive Property )

Therefore, Using Transitive Property, it is found that b + 3 is equal to 12.

Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%. Its current value is $2,000. The equation represents the situation, where t is the age of the car in years and r is the rate of depreciation. About how old is Devon's car? Use a calculator and round your answer to the nearest whole number.

Answers

Given :

Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%.

Its current value is $2,000.

To Find :

Age of car.

Solution :

Price of car after 1 year :

[tex]P_1=P_o(1-0.35)[/tex]

Price of car after 2 year :

[tex]P_2=P_1(1-0.35)\\\\P_2=[P_o(1-0.35)](1-0.35)\\\\P_2=P_o(1-0.35)^2[/tex]

So, price of car after n years.

[tex]P_n=P_o(1-0.35)^n[/tex]

[tex]2000=16000(1-0.35)^n\\\\0.65^n=0.125\\\\n\times log(0.56)=log(0.125)\\\\n=\dfrac{log(0.125)}{log(0.56)}\\\\n=3.58[/tex]

Therefore, age of car in nearest whole number is 4 years.

Hence, this is the required solution.

1. Write the equation of a line parallel to y = -2x + 10 that passes through point (2, 4). ​

Answers

Answer:

y - 4= -2(x - 2)

Step-by-step explanation:

(This answer is in point slope form, if you need the answer in a different form like slope intercept, you would have to distribute the negative 2 and bring the negative 4 to the right side.)

So, you know the line is parallel to the equation y= -2x + 10. We know that parallel lines must have the same slope, so the answer will have a slope of negative 2. Because they have given you a point that the line passes through, we are going to put the answer in point slope form. we know a point and we know the slope, hence it is called point-slope.

Point slope form is y - y₁ = m(x - x₁). The m stands for the slope, and the x₁ and y₁ is where you will plug in the x and y coordinates (2,4) .

So to plug in the numbers into point slope form it would be y - 4 = -2 (x - 2). hope this helped :)

Hans is using frequent flier miles to fly to a location 750 miles away, but the airline he is using still charges $20.19 for fees and taxes and $0.15 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.15x + $20.19 How much did Hans pay for his trip?

Answers

Answer:

Cost of the trip = $132.69

Step-by-step explanation:

Given:

Total distance = 750 mile

Fixed charge = $20.19

Variable charges = $0.15 per mile

Find:

Cost of the trip

Computation:

Y = $0.15x + $20.19

Y = $0.15(750) + $20.19

Y = $132.69

Cost of the trip = $132.69

Prove that in a triangle the length of any altitude is smaller than the sides that are meeting at the altitude's vertex.

Answers

The proof here would be based on the use of the Pythagoras theorem in trigonometry.

How to prove that the length of the altitude are smaller

In a triangle getting the altitude or height will result to producing a right angled triangle. In trigonometry, a right angled triangle have the sides as the hypotenuse, the adjacent and the opposite. in this case the altitude is either the opposite or adjacent.

From Pythagoras Theorem, the hypotenuse. equals the square root of the sum of squares of the other two sides. hence is the longer side. Each leg of this triangle would be shorter than the hypotenuse. The two sides that meet at the vertex are the adjacent or the opposite and the hypotenuse.

b. $15,219
$23,214
d. $30,886
a
С.

Answers

Answer:

Katherine will receive $23214 to the nearest dollar from both investments.

Step-by-step explanation:

Simple interest = Principal × Time × rate

Le's work out the interest Katherine earns from the two investments.

Money Market Account

Simple interest = 7770 × 5.8/100 × 6/12

= 7770 × 0.058 × 0.5 =  $225.33

So, the amount she gets at maturity is:

$7770 + $225.33= $7995.33

CD account

Simple interest = 12500 × 0.0725 × 3 = $2718.75

The amount she receives at the end of period is:

$12500 + $2718.75 = $15218.75

The total amount she receives from both investments at maturity is:

$15218.75 + $7995.33 = $23214.08

This to the nearest dollar is:

= $23214

Which table could represent a function?
1. 1:4,2:2, 3:4, 2:6
2. 1:2, 2:4, 3:6, 4:2
3. 2:6, 0:4, 1:6, 2:2
4. 2:2, 3:2, 4:6, 3:6

Answers

The answer is the 2nd one

The table that represents a function is 1:2, 2:4, 3:6, 4:2.

Option 2 is the correct answer.

Given,

Function table:

1. 1 → 4,  2 → 2, 3 → 4,  2 → 6

2. 1 → 2, 2 → 4, 3 → 6, 4 → 2

3. 2 → 6, 0 → 4, 1 → 6, 2 → 2

4. 2 → 2, 3 → 2, 4 → 6, 3 → 6

We need to find which one is a function.

What is a function?

A function has an input and an output.

We can have different inputs and the same output.

Example:

f(x) = x²

x = 1, -1 are the inputs

f(1) = 1

f(-1) = 1

- We see that we have the same output 1 with different inputs 1 and -1.

i.e Many to one

- But we can not have the same inputs and different outputs.

i.e One to many

- We can have one-to-one in a given function.

We have,

1. 1 → 4,  2 → 2, 3 → 4,  2 → 6

Here,

2 → 2 and  2 → 6 = one to many.

We have the same inputs but different outputs which is not possible.

It is not a function.

2. 1 → 2, 2 → 4, 3 → 6, 4 → 2

Here,

1 → 2 and 4 → 2 =  many to one

2 → 4 and 3 → 6 = one to one

It is a function.

3. 2 → 6, 0 → 4, 1 → 6, 2 → 2

2 → 6 and 2 → 2 = one to many

This is not possible.

It is not a function.

4. 2 → 2, 3 → 2, 4 → 6, 3 → 6

3 → 2 and  3 → 6 = one to many

This is not possible.

It is not a function.

Thus the table that represents a function is 1:2, 2:4, 3:6, 4:2.

Option 2 is the correct answer.
