-7x-2y=-13
-3x-2y=-12 by substitution

Answers

Answer 1
Answer:

Answer: x = 0.25, y = 5.625 or ((1)/(4), (45)/(8))

Step-by-step explanation:

    To solve by substitution, we will first isolate one of the variables in one of the given equations.

         -7x - 2y = -13 ➜ y = -3.5x + 6.5

    Then, we will substitute this into the other given equation and solve for x.

         -3x - 2y = -12

         -3x - 2(-3.5x + 6.5) = -12

         -3x + 7x - 13 = -12

         4x = 1

         x = 0.25

    Lastly, we will substitute this value of x into the equation we solved for to find y.

         y = -3.5x + 6.5

         y = -3.5(0.25) + 6.5

         y = 5.625

Volume is measured in cubic units true false

Answers

Answer:

The statement is true.

Step-by-step explanation:

Volume is the measurement of the space occupied by any object. Thus, mathematically, we can represent volume as the product of area and height.

Thus, we have

Volume = Area × height

Now, we know that area is measured in square units and height is in units.

Thus, we have

Volume = Square units ×units

Volume = cubic units.

Therefore, we can conclude that volume is measured in cubic units.

Thus, the statement is true.

Volume is measured in cubic units is true statement.

Volume is a measurement of the amount of space occupied by a three-dimensional object.

It is expressed in cubicunits because it involves measuring the extent of the object in three dimensions: length, width, and height.

When these dimensions are multiplied together, the result is a quantity that represents the volume of the object.

Hence, volume is measured in cubic units is true statement.

Darryl’s credit card has a minimum monthly payment of 2.51% of the card’s balance. If Darryl currently owes $1,431.72, what is his minimum payment, to the nearest cent?

Answers

Darryl’s credit card has a minimum monthly payment of 2.51% of the card’s balance.
Darryl currently owes $1,431.72. Let's solve his minimum payment.
=> 1,431.72 * 0.0251 = 35.94 dollars
=> 1,431.72 + 35.94 dollars = 1467.656172 or 1467.7 dollars.

Answer:

$35.94.

Step-by-step explanation:

We have been given that Darryl’s credit card has a minimum monthly payment of 2.51% of the card’s balance. Darryl currently owes $1,431.72.

To find the minimum payment we will have to calculate 2.51% of $1431.72.

\text{Minimum monthly payment}=(2.51)/(100)*\$1,431.72

\text{Minimum monthly payment}=0.0251*\$1,431.72

\text{Minimum monthly payment}=\$35.936172

Upon rounding our answer to nearest cent we will get,

\text{Minimum monthly payment}\approx \$35.94

Therefore, the minimum monthly payment to the nearest cent will be approximately $35.94.

Which inequality below will have a dashed boundary line with a shaded area above its graph? A. 7x − y ≤ 3 B. x − y ≤ 4 C. 2x − 9y > 2 D. 4x + 7y > 3

Answers

Dashed boundary line means there is no equal sign in the problem. That eliminated the first two. Shaded above means it is greater than...

Now turn your inequalities into y = mx + b form
 2x - 9y > 2 --- subtract 2x from both sides
-9y > -2x + 2 -- divide by -9...and change inequality sign
y < 2/9x - 2/9 this says y is less then.....we need greater then...this is not it

try the next one...
4x + 7y > 3 --- subtract 4x from both sides
7y > 4x + 3 -- divide by 7
y > 4/7x + 3/7
this says y is greater then...this is the one we want
