Answer:

x= -3,      x = 1

Step-by-step explanation:

Zeros are values of x, when f(x) = 0.

0=(x+3)(x-1)

x+3 = 0,  x - 1=0

x= -3,      x = 1

Answer:

x = -3, x = 1

Step-by-step explanation:

To determine the zeroes of the factored quadratic equation, we need to look back at its definition. The zeroes are a function are specific x-values that result in a y-value of 0.

In this case, we want the numbers inside of the parantheses to equal 0. If we substitute in x = -3, we get (0)(x - 1), and we know that is just 0. Similarly, if we substitute in x = 1, we get (x + 3)(0), and we know that is just 0.

As such, these are your solutions.

Find the length of side FD given that
Dafna1 [17]

Answer:

4

Step-by-step explanation:

Find the length of side FD given that

Since both triangles are similar, then

AB= FD

2x+2 = x+3

Collect like terms

2x-x =3-2

x = 1

Get FD

FD = x+3

FD = 1+3

FD = 4

Hence the measure of FD is 4

How many unique triangles can be made when one angle measures 90° and another angle is half that measure?
valina [46]
In a right-triangle, if either of the other two angles are "half that measure", or half of 90°, that means 45°, then the last angle will also have to be a 45° one too, and the sides coming from the 90° angle, will be equal twins, and therefore they can only make up one type-length hypotenuse, and due to that, you can only make that one triangle.  Check picture below.

Match the inequality with its line graph.
zepelin [54]

Answer:

The answer to your question is below

Step-by-step explanation:

A) 2x > -6

   x > -6/2

   x > -3

   It must be a graph with an open circle starting at -3 and then to the right.

   It is the first graph.

B) x - 4 < -7

   x < -7 + 4

  x < -3

  The graph must be an open circle starting at -3 and pointing to the left.

  it is the second graph.

C) 6 + x ≤ 3

    x ≤ -6 + 3

    x ≤ -3

   The graph must be a closed circle starting at -3 and pointing to the left.

   it is the forth graph.

D) -x - 5 ≤ -2

    -x ≤ -2 + 5

   - x ≤ 3

     x ≥ -3

    The graph must be a closed circle starting at -3 and pointing to the right.

    It is the third graph.
