Create a system of linear equations that when solved algebraically, prove to have no solution.

Basically, you just need to make them have the same slope, but a different y - intercept. That means they'll never intersect, so will have no solution.

Say one equation is

y = 3x + 5

That means the other can be something like

y = 3x + 6

Right? Because if

3x + 5 = 3x + 6

and you subtract 3x from both sides

5 = 6

which can't be true.

< ADF measures 2x degrees and < FDC measures x + 12 degrees. What is the measure

gtnhenbr [62]

Answer:

<h2>Angle ADF is equal to 52° and angle FDC is equal to 38°.</h2>

Step-by-step explanation:

In the image attaches, you can observe that angles ADF and FDC are complementary angles, because they sum 90°.

$\angle ADF + \angle FDC = 90\°$

And we know that

$\angle ADF=2x\\\angle FDC = x+12$

Replacing these expressions, we have

$2x+x+12=90\°\\3x=90\° - 12\°\\x=\frac{78}{3}\\ x=26$

Then, we replace this value in each expression to find both angles measures.

$\angle ADF= 2(26)=52\°\\\angle FDC = 26+12=38\°$

Therefore, angle ADF is equal to 52° and angle FDC is equal to 38°.

What is the 45th digit in the decimal equivalent of 3/7

ruslelena [56]

Answer:

1/7 = 0.142857 since this decimal is repeating divide 45/6(number of repeating numbers) and it gives you 7.5 so you know that it repeats this sequence 7 times plus an extra 3 numbers so the 45th decimal is 2

If the translation is (x+1, y-4) and the image is (1,7), what is the preimage

EleoNora [17]

Answer:

The pre-image is the point (0,11)

Step-by-step explanation:

we know that

The rule of the translation is equal to

pre-mage------> image

(x,y) -----> (x+1,y-4)

we have that

(x+1,y-4)=(1,7)

x+1=1 -----> x=1-1=0

y-4=7 ----> y=7+4=11

therefore

The pre-image is the point (0,11)
