vodka [1.7K]3 years ago
7 0

Answer:

A

Step-by-step explanation:

Both vectors have the same length/ magnitude, so they are equal and since they are going the same direction, they're also parallel and won't touch.

3 times what equal 19?
MissTica

Answer:

6 1/3

Step-by-step explanation:

3 times what equals 19 can be in the form of an equation as shown below. It shows that the value we are finding for is unknown, therefore it is a variable. A variable is the unknown value in an equation.

Equation: 3x = 19

With the equation in hand, we can now solve the problem easily.

3x = 19

Carry the 3 to the 19(Carry over the like terms across leaving the variable or the unknown)

x = 19÷3

x = 6.33333 or 6 1/3

To check if the answer was correct:

3 × 6 1/3 = 19

You regain the answer <em>19</em>

Answer:

-3/8

Step-by-step explanation:

PemDas

2/3 x 3/4= 1/2

3/4 x -1/2 = -3/8

full equation is now

1/2 - 1/2 + -3/8

1/2-1/2 =0

-3/8 remains

3. Which statements about the line that passes through (-2, 0) and (2, -4) are true?
diamong [38]

Answer:

B, C, and D.

Step-by-step explanation:

Let's go through each answer choice.

A: To find the slope of a line from two points, we use this formula: (y_2-y_1)/(x_2-x_1). Plugging in the values (-2,0) and (2, -4), we get:

  • (-4-0)/(2+2)
  • -4/4
  • -1

Because option A says the slope is 1, but we got -1, option A is false.

B: To find the y-intercept, we use this formula: b = y_1 - m * x_1

  • b = 0 -(-1) * (-2)
  • b = 1 * (-2)
  • b = -2  

Since we know the value of b is the y-intercept, we could write the y-intercept as (0,-2). Therefore, option B is true.

C: The equation of a line (in slope-intercept form) is y = mx + b, where y - y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. Since we already solved for the y-intercept and slope, let's plug in those values:

  • y = mx +b
  • y = -x -2

As you can see, the equation we got here matches the one in option C, meaning it's true.

D: We know that a point is written like this: (x, y). If the x-coordinate is not zero but the y-coordinate is, then it's the x-intercept. Since the question says that (-2,0) is one of the points the line passes through, and option D says that the x-intercept is (-2,0), it's true.
