Which value, when placed in the box, would result in a system of equations with infinitely many solutions?y = 2x – 5

2y – 4x =

a. –10
b. –5
c. 5
d. 10

Answers

For a system of equations to have infinitely many solutions, the equations have to be lineary dependent, (i.e. one of the equations is a multiple of the other equation). For the given equation to have infinitely many solutions, the second equation have to be a multiple of the first equation. The first equation can be rewritten as y - 2x = -5 The second equation is the first equation multiplied by 2, i.e. 2(y - 2x= -5) = 2y - 4x = -10 Therefore, the correct answer is -10 (option a).

Answer:

-10

Sujay maxed out his credit card at $5,000. The interest rate is 11.75%. Using an online calculator, Sujay determines that if he stops using the card and pays $400 per month for the next 14 months, he will pay off his debt. How much interest will Sujay have paid when his credit card balance is $0

Answers

His debt is 5000 dollars with 11.75% interest rate.
Now, he used online calculator and realize that he needs 14 months to pay off his debt paying 400 dollars per month
=> 400 * 14 months = 5 600 dollars.
His debt is only 5000, thus he paid 600 for interest

Answer:

600$

Answer:

x = 154/13

Step-by-step explanation:

You are given the measures of all three angles in a triangle

so according to the Triangle Sum Theorem:

∠MNO + ∠OMN + ∠NOP = 180

1. Substitute the measures of the angles into the equation:

(3x + 11) + (2x + 20) + (8x - 5) = 180

2. Combine like terms:

(3x + 2x + 8x) + (11 + 20 -5) = 180

13x + 26 = 180

3. Isolate x by subtratcing 26 from both sides

13x + 26 -26 = 180 -26

13x = 154

4. Solve for x by dividing both sides by 13

13x/13 = 154/13

x = 154/13

A 36 inch by 48 inch poster is reduced to an image that is 3 in by 4 inch in size. What is the scale factor?A: 1/3
B: 1/6
C: 1/9
D: 1/12

Answers

The correct answer for the question that is being presented above is this one: "D: 1/12."
The original dimension is 36 x 48.
The scaled dimension is 3 x 4.

The ration between 3 and 36 ; 4 and 48 is reduced to 1/12.
So the scale factor is 1/12.
