-7, -3, 1, 5 what is the explicit formula

Mathematics

Vadim26 [7]3 years ago

Answer:

f(x)=4x-11

Step-by-step explanation:

This is a linear sequence, so we have to find our common difference, or slope, by finding the difference between any term and its previous term. We should do this a couple of times to make sure it's consistent. In this case, our slope is 4 and our first term is -7. We can do our equation in slope intercept (y=mx+b) form. However, to do this, we have to find the '0'th' term, or the term where x=0, a.k.a. the y-intercept. Our 1st term where x-1 is -7, and since our common difference is 4, we subtract 4 from negative 7 to get a y-intercept of -11. Our equation is now y=4x-11. To make this an explicit formula, we convert into f(x) form to get a formula of f(x)=4x-11.

A straight line with the equation y=ax-3 goes through the point (2,11). Work out the value of a
Rzqust [24]

The value a is 7.

<h3>What is Straight Line?</h3>

A line is simply an object in geometry that is characterized under zero width object that extends on both sides. A straight line is just a line with no curves.

Here, the given equation of line

      y = ax -3

line passing through point (2, 11), then

    11 = a X 2 - 3

    11 + 3 = 2a

     2a = 14

      a = 7

Thus, the value a is 7.

Drag each shape to the correct location on the image. Not all shapes will be used. Complete each shape with the missing half so
Sav [38]

Answer:

  see attached

Step-by-step explanation:

Perhaps the easiest way to do this is to draw the needed shape in the box, then locate it among the answer choices. Use the identifying features such as dot location and direction of arrow (or tail).

__

Left-to-right, this is what you're trying to match:

  1. tail on the right, dot in the tail
  2. tail on the left, dot in the fin
  3. tail on the right, dot in the nose
  4. tail on the left, dot in the center

If ABCDE is reflected over the x-axis and then translated 3 units left, what are the
Aloiza [94]

Answer:

(-6,1)

Step-by-step explanation:

A. Reflection

When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign.

Thus, D (-3,-1) ⟶ D' (-3, 1)

B. Translation

When you translate a point horizontally, its x-coordinate changes, but the y-coordinate. remains unchanged.

You translated the point 3 units to the left.

D'(-3, 1) ⟶ D"(-6,1)
