Okay so my test said (using elimination (add or sub) find the solution to the following system of equations. 5x+3y=9 2x -3y=5) and I’m confused

Answers

Answer:

x = 2, y = -1/3

Step-by-step explanation:

I'm pretty sure the question is asking for the values of x and y. By finding these values you will need to use elimination.

Equations given:

5x + 3y = 9

2x - 3y = 5

To find x:

5x + 3y + 2x - 3y = 9 + 5  (add to eliminate y to solve for x)

7x = 14

x = 2

To find y:

5(2) + 3y = 9

10 + 3y = 9

3y = -1

y = -1/3

Therefore, x = 2 and y = -1/3

7. Find DE.

Answers

Answer:

DE = 37

Step-by-step explanation:

AD = DC and BE=EC ⇒

DE = 1/2AB

4x + 1 = 1/2(11x - 25)2(4x + 1) = 11x - 258x + 2 = 11x - 2511x - 8x = 2 + 253x = 27x = 27/3x = 9

DE = 4*9 + 1 = 36 + 1 = 37

Given:

AD = DC

BE = EC

It gives that 2(DE) = AB

To Find:

The length of DE.

Explanation:

According to the question,

2(DE) = AB

By putting the respected values, we get

2( 4x + 1 ) = 11x - 25

or, 8x + 2 = 11x - 25

or, 25 + 2 = 11x - 8x ( transposition method )

or, 27 = 3x

or, x = 27/3 = 9

The value of x is 9.

DE = 4(9) + 1 = 36 + 1 = 37

Answer:

DE = 37

The x-intercept of the graph is given as (-2, 0)

The intercept of a line

Given the equation of a line expressed as:

y + 2 = 2(x+3)

We are to find the x-intercept of the line. The x-intercept occur at the point where y = 0

Substituting y = 0 into the equation will give;

y + 2 = 2(x+3)

0 + 2 = 2(x+3)

2 = 2x + 6

2x = -4

x = -2

Hence the x-intercept of the graph is given as (-2, 0)

During the life of a $2500 loan, the interest paid is $318.75. If the interest rate is 8.5%, how long was the loan?

Answers

Answer:

1.5 years

Step-by-step explanation:

Simple Interest I = PRT

Principal = 2500, Rate R= 8.5%, SI = 318.75, T = ?

Now, substituting the above value

318.75 = 2500*0.085 * T

T = 318.75 / 2500*0.085 years

T = 318.75 / 2500*0.085 years

T = 318.75 / 212.5 years

T = 1.5 years

An isosceles triangle has a perimeter of 50 cm. The congruent sides
measure (2x + 3) cm. The length of the third side is 7x cm. What is the
value of x?

Answers

Answer:

4

Step-by-step explanation:

As, the measure of one congruent side is = 2x + 3

So, bc there are 2 congrent sides, =( 2x + 3) + (2x +3) = 4x + 6

Now perimeter= the length of the 2 sides + third side

Perimeter = (4x + 6) + (7x) = 50 cm

So, 11x + 6 = 50

So, 11x = 50 - 6 = 44

11x = 44

x = 44/11

x = 4cm.
