Answer:

Option B.

a

Step-by-step explanation:

Given:

-3( -x + a ) + 7 < 5     When x = -1

To Find:

a ?

Solution:

-3( -x + a ) + 7 < 5     When x = -1

Substitute x = -1 in above  we get

-3(-(-1) + a ) + 7 < 5

-3(1 + a) < 5 - 7

Using Distributive Property we get i.e A(B+C) = AB + AC

\therefore -3\times 1 +(-3)\times a

I am sketching parabolas and my book is telling me that I need only two points. But I don't know how I am meant to sketch the pa
Sever21 [200]

Answer:

In order to sketch a parabola, one will typically use the y-intercept, the x-intercepts, and the vertex.

Step-by-step explanation:

In order to sketch a parabola, one will typically use the given equation in standard form, y = ax^2 + bx + c, and:

  • The y-intercept – the point where the parabola crosses the vertical axis – by substituting 0 for all <em>x</em> values in the given equation and solving for <em>y</em>.
  • The x-intercepts – the points where the parabola crosses the horizontal axis – by setting the given equation equal to 0 (i.e., <em>y</em> = 0) and finding the factors (or roots).
  • The vertex – the point of symmetry where the parabola changes direction and curves up or down – by using x=\frac{-b}{2a} to find the x-coordinate then plugging that value into the given equation to find the y-coordinate.

What does interior angle A of the polygon in the figure equal?
Lerok [7]
<span>Based on the attached image, the interior angle A of the polygon in the figure equal 110 degrees. If you can see the image the angle A is equal to the angle on the other side. The angle A is an example of obtuse angle because has the size of more 90 degrees and less than 180 degrees. All the angles in the image are obtuse except the one angle in the top that measures 50 degrees.</span>

a baby carriage is sitting at the top of a hill that is 21 m high. The carriage with the baby has a mass of 5kg whats the energy
Westkost [7]
The first thing you should remember is that the energy in this case will be given by the work done.
 The work is defined as:
 W = F * d
 Where
 F = Force
 d = displacement.
 Calculate it. 
 5 kg x 9.8 m / s ^ 2 x 21 m = 1029 J
