Answer:

Option B. The given equation can have infinitely many solutions.

Solution:

The equation will have infinitely many solution.

As given equation is,

$-3y +3y+4 = 4$

$\Rightarrow -3y +3y = 4-4$

$\Rightarrow 0\times y =4-4$

$\Rightarrow 0\times y = 0$

$\Rightarrow y = \frac{0}{0}$ = infinity or undefined.

(// as we know anything divided by 0 is infinite)

Hence, the equation can have infinitely many solutions.

Evaluate each expression |-16| -|-1|

Maslowich

Understanding the Absolute Value.

First, know what the absolute value is.

The absolute value is the value that determines how far the value is from 0.

For example, The absolute value of -5 is far from 0 5 units. Therefore the absolute value of -5 equals 5.

Basic Absolute Value Defines

| a | = a

- | a | = -a

| - a | = a

Back to the question. To evaluate those expressions, we use the defines of absolute value.

|-16| = 16

|-1| = 1

16-(1)

Then remove the brackets. 16 - 1 = 15

Therefore, the answer is 15.

The answer above is when being subtracted and evaluated from both 16-1

Evaluating for each expressions would be

|-16| = 16

-|-1| = -1

What are the characteristics of the graph of the inequality x ≤ -8?

Mumz [18]

2 Answers:

Choice C) It will use a closed circle

Choice D) The ray will move to the left

=========================================================

Explanation:

The inequality $x \le -8$ means that x = -8 or x < -8. Since we're including -8 itself, which is the endpoint, we'll use a closed circle. In contrast, an open circle would be used if the inequality was $x < -8$ to exclude the endpoint -8.

The ray is to the left because we're visually describing all values smaller than -8. Such example values are -10 and -22 as these values are to the left of -8 on the number line.

In short, the graph consists of a closed circle at the endpoint -8 and the arrow is to the left. We can say the shading is to the left.

Two jets simultaneously started traveling in opposite directions from the same airport. Four hours later they were 3800 miles ap

Basile [38]

Step-by-step explanation:

the slower plane traveled x miles in 4 hours.

the faster plane traveled x + 4×80 = x + 320 miles in 4 hours.

so,

x + x + 320 = 3800 miles

2x =3480 miles

x =1740 miles (in 4 hours) .

that means the slower plane's speed was 435 mph.

and the faster plane's speed was 435 + 80 = 515 mph.

Can someone explain how the following Matrix can be multiplied? I thought the column of the first matrix had to match the row of

natita [175]

You are correct in thinking that the columns of the first matrix must match with the rows of the second matrix.

So for example, we can multiply a 1 x 5 matrix with a 5 x 7 matrix. The two matching '5's are directly what make multiplication possible in this case. For your problem, the first two '3's match and multiplication is possible.

The rows of the first matrix don't need to match with the columns of the second matrix.
