Solve the following system of equations: -2x + y = 1 -4x + y = -1

1 answer:

3 0

With Elimination system:
Substract -4x + y = -1 with -2x + y = 1
and... the result: 2x = 2, so x = 1

Subtitution: -2x + y = 1
⇔-2 . 1 + y =1
⇔ -2 + y = 1
⇔y = 3

The final answer is D ( 1, 3)

Which represents the inverse of the function f(x) = 4x?

Licemer1 [7]

Answer:

The inverse is 1/4x

Step-by-step explanation:

y = 4x

To find the inverse, exchange x and y

x = 4y

Solve for y

1/4 x = 4y/4

1/4x = y

The inverse is 1/4x = y

C and D are mutually exclusive events. Find P(C or D). P(C)= 3/7= P(D)= 4/7 P(C or D)

IgorLugansk [536]

Answer:

$P(C\ or\ D) = 1$

Step-by-step explanation:

Given

$P(C) = \frac{3}{7}$

$P(D) = \frac{4}{7}$

Required

$P(C\ or\ D)$

Since the events are mutually exclusive, then:

$P(C\ or\ D) = P(C) + P(D)$

So, we have:

$P(C\ or\ D) = \frac{3}{7} + \frac{4}{7}$

Take LCM

$P(C\ or\ D) = \frac{3+4}{7}$

$P(C\ or\ D) = \frac{7}{7}$

$P(C\ or\ D) = 1$

Fill in the blank with the appropriate angle:

Gre4nikov [31]

Answer:

Step-by-step explanation:

Same side interior angles refers to the pair of angles which are inside the two "parallel" lines and at the same side of the transversal line.

Notice that angles BGH and DHG are same side interior angles. Similarly, angles AGH and CHG are also same side interior angles.

Therefore, the right answer is ∠DHG.

Step-by-step explanation:

3/8 × 4/5 = 12/40 less than

4/3 × 3/8 = 12/24 greater than

4/4 × 3/8 = 12/32 equal to

3/8 × 1/4 = 3/32 less than

3/8 × 1 = 3/8 equal to
