Use the law of syllogism to form a conclusion from the given premises.

Premise 1: If a polygon was translated to the right, then its image is congruent to its pre-image.

Premise 2: If an image is congruent to its pre-image, then a rigid transformation was performed.

Select from the drop-down menus to correctly complete the conclusion.

Conclusion: If a polygon was translated to the right, then a rigid transformation was performed

this is right i just took the test

Determine the solution to the system of equations below.

Yanka [14]

Answer:

$\boxed{\sf{x=7 \quad y=2}}$

Step-by-step explanation:

To solve this problem, isolate it on one side of the equation.

x-3y=1: x=1+3y

x=1+3y

Substitute.

x=1+3y= 3(1+3y)-5y=11

Solve.

3+4y=11

Subtract by 3 from both sides.

3+4y-3=11-3

Solve.

11-3=8

Rewrite the problem down.

4y=8

Divide by 4 from both sides.

4y/4=8/4

Solve.

8/4=2

y=2

x=1+3y

x=1+3*2

Solve.

1+3*2

Multiply.

3*2=6

Add.

1+6=7

x=7

Therefore, the correct answer is x=7 and y=2.

Last week at Best Bargain, 75% of the computers sold were laptops. If 340 computers were sold last were, how many were laptops?

QveST [7]

Answer:

255

Step-by-step explanation:

We need to find 75% of 340...

75%*340

Let's convert 75% to a fraction to make the math easier...

75/100*340

Now let's simplify 75/100 to again make it easier...

3/4*340=255

Ms. Fuller has 8/3 pies left over from her party. How can you write the number of pies she has left over as a mixed number?

PolarNik [594]

8/3 is an improper fraction, to make it proper you find out how many times 3 goes into 8 (which is 2). So then you have 2 and two times 3 is 6. This does not equal 8 yet so you do 8-6=2 You put this number over the denominator 3. So your final answer is 2 2/3.

Which equation can be solved using the expression -3 plus or minus the square root of (3)^2+4(10)(2)/2(10) for x?

monitta

Answer: B. 2=3x+10x^2

Step-by-step explanation:

The expression means the quadratic function equation.

B = 10x^2 + 3x -2 = 0

the equation is [-b ±√(b^2 -4ac)]/2a

b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.
