given the system of linear equations:

2x+1/2y=7
6x-1/2y=5

which new equation would be the result of adding the equations together?

4x=2

8x=2

8x=12

y=12

Answers

Answer 1

Answer:

8x=12 cause y would cancel out and then you just add 2 and 6, and 7 and 5.

PLEASEE SOMEONE HELPPP!!!
From Get Engaged! Part 1, if you thought that the monthly payment is the most important factor for Juan to consider, then you are correct. He should still consider the amount of interest that he will be paying, but if he can only pay a certain amount each month, he is not able to pick a payment plan based only on interest.

How can Juan compare the amount of interest of the two plans he has been presented with? Juan will need to multiply … _______________________________.


Great work! In order to find out how much Juan will pay in interst for each plan (3 years versus 5 years), we have to start by finding out how many months are in 3 years and 5 years. Since there are 12 months in one year, you can multiply 12 x 3 and 12 x 5.


PLAN 1: In the first plan, Juan pays $456 for 36 months. 456 x 36 = $16,416. The cost of the car is $15,000. In order to find the interest, we have to find the difference between the total amount that Juan would pay and the cost of the car: 16,416 - 15,000 = $1,416 in interest.

PLAN 2: In the second plan, Juan pays $289 for 60 months. 289 x 60 = $17,340. The cost of the car is $15,000. In order to find the interest, we have to find the difference between the total amount that Juan would pay and the cost of the car: 17,340 - 15,000 = $2,340 in interest.1) What is the benefit to paying a higher monthly payment for less time?

1) What is the benefit to paying a higher monthly payment for less time?

2) What is the benefit to paying a lower monthly payment for longer?

Answers

Answer: $450 i think. hope this

aking additional principal payments will shorten the length of your mortgage term and allow you to build equity faster. Because your balance is being paid down faster, you'll have fewer total payments to make, in-turn leading to more savings.

and the 2) because your monthly payments are lower on a loan with a longer repayment term, this gives you more wiggle room in your budget. You may need this extra cash to put towards other important goals.

Step-by-step explanation:

Box 2:
length
• width • height = (4x-1). x•x^3?
volume = 4x^5 -x
Degree of length:
Degree of width:
Degree of height:
Degree of volume:
DONE

Answers

Answer:

1.) Volume= Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is  Length × Width × Height

2.) Terms in this set (4)

Measure 50 ml of water into a gradulated cylinder.

Place object in cylinder and measure the new volume.

Subtract the 50ml from the new volume.

The difference in the volume is the volume. of the object.

3.) Graduated cylinders

4.) Particles behave differently within each state of matter: solid, liquid, and gas. The particles give matter a property called mass. The mass of an object is related to the amount of material that makes up the object and how hard the object is to move. Simple experiments can show how gases have mass.

Explanation:

1.) Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.

SI unit: Cubic metre

In SI base units: 1 m3

2.) If the object has an irregular shape , the volume can be measured using a displacement can . The displacement can is filled with water above a narrow spout and allowed to drain until the water is level with the spout. As the irregular object is lowered into the displacement can, the water level rises.

3.) Today they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).

4.) Mass is a measure of the amount of matter in an object. Mass is usually measured in grams (g) or kilograms (kg). ... An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity. Your mass on the earth and the moon are identical.

~-Long Story short, its 1 = Degree of Length

                                     1 = Degree of Width

                                     3 = Degree of Height       That's is all summed up!-~

                                     5 = Degree of Volume

                   Ⓗⓞⓟⓔ ⓣⓗⓘⓢ Ⓗⓔⓛⓟⓔⓓ❕  

                                                              ~

The degrees of the given dimensions are degree of length= 1 ,degree of width = 1 , degree of height= 3 , degree of volume = 5

To determine the degree of each dimension and the volume for Box 2, let's consider the expressions:

Length = (4x - 1)

Width = x

Height = x³

Volume = Length × Width × Height

Volume = (4x - 1) × x × x³

Now, let's simplify the volume expression:

Volume = (4x² - x) × x³

Volume = 4x⁵ - x⁴

Now, let's find the degrees of each dimension and the volume:

Degree of length:

The degree of the length dimension is the highest power of x in the expression (4x - 1). The highest power of x in this expression is 1.

Degree of width:

The degree of the width dimension is the highest power of x in the expression x. The highest power of x in this expression is 1.

Degree of height:

The degree of the height dimension is the highest power of x in the expression x³. The highest power of x in this expression is 3.

Degree of volume: The degree of the volume is the highest power of x in the expression 4x⁵ - x⁴. The highest power of x in this expression is 5.

Therefore, the degrees are as follow,

Degree of length: 1

Degree of width: 1

Degree of height: 3

Degree of volume: 5

Step-by-step explanation:

because i just know

The direct variation has the same value or expression as that of the slope of a straight line given by - m = y/x.

What is the general equation of a straight line?

The general equation of a straight line is -

y = mx + c

where m is slope of line

c is the y - intercept

Given is the direct variation of a quantity.

The direct variation of a quantity in the equation of a straight line is represented by the slope of a straight line. Mathematically, we can write -

y = mx + c

for y - intercept = [c] = 0, we can write -

y = mx

m = y/x

which is the representation of direct variation.

Therefore, the direct variation has the same value or expression as that of the slope of a straight line given by - m = y/x.

The volume V of a solid right circular cylinder is given by V = πr2h where r is the radius of the cylinder and h is its height. A soda can has inner radius r = 1.5 inches, height h = 6 inches, wall thickness 0.04 inches, and top and bottom thickness 0.07 inches. Use linearization to compute the volume, in cubic inches, of metal in the walls and top and bottom of the can. Give your answer to 2 decimal places.

Answers

Answer:

8.20in³

Step-by-step explanation:

Given V = πr²h

r is the radius = 1.5in

h is the height = 6in

thickness of wall of the cylinder dr = 0.04in

top and bottom thickness dh 0.07in+0.07in = 0.14in

To compute the volume, we will find the value of dV

dV = dV/dr • dr + dV/dh • dh

dV/dr = 2πrh

dV/dh = πr²

dV = 2πrh dr + πr² dh

Substituting the values into the formula

dV = 2π(1.5)(6)•(0.04) + π(1.5)²(6) • 0.14

dV = 2π (0.36)+π(1.89)

dV = 0.72π+1.89π

dV = 2.61π

dV = 2.61(3.14)

dV = 8.1954in³

Hence volume, in cubic inches, of metal in the walls and top and bottom of the can is 8.20in³ (to two dp)

What is the greatest common factor?

The GCF (Greatest Common Factor) of two or more numbers is the greatest number among all the common factors of the given numbers. The GCF of two natural numbers x and y is the largest possible number that divides both x and y without leaving any remainder. To calculate GCF, there are three common ways- division, multiplication, and prime factorization.

Now, 300=2×2×3×5×5

750=2×3×5×5×5

900=2×2×3×3×5×5

So, GCF of 300, 750 and 900=2×3×5×5=150

       5 x (X /1)  = 6 x 10

  We know that any number divided by 1 will give back that same number; so the value of the expression in the parentheses is x
