Answer:

What you found were the x-intercepts of the quadratic function. Here's how you would write it- (2,0), (-9,0).

I think finding the zeroes of a function is equal to finding the x-intercepts, so I believe the two terms can be used interchangeably.

Hope I helped, have a nice day, also please correct me if I did anything wrong

Answer:

-9, 2

Step-by-step explanation:

f(x) = x^2 +7x -18

Set the function equal to zero

0 = x^2 +7x -18

Factor.  What two numbers multiply to -18 and add to 7

9*-2 = -18

9+-2 = -7

0 = (x=9) (x-2)

Using the zero product property

x+9=0    x-2 =0

x=-9   x=2

You can also write in coordinate pairs

(-9,0) and (2,0)

Lines g, h, and I are parallel and m < 2 =129
vampirchik [111]

Answer:

All angles in this diagram are 51 or 129. See below for a specific angle.

Step-by-step explanation:

Parallel lines cut by a transversal have specific angle relationships.

  • Alternate Interior Angles are angles across the transversal between pairs of parallel lines. These angles are congruent. Example: 3, 6, 7, and 10 are all congruent and are pairs of alternate interior angles. 4, 5, 8, and 9 are congruent as well.
  • Alternate Exterior Angles are angles across the transversal outside of the parallel lines. These angles are congruent. Example 2 & 11 are congruent alternate exterior angles. 1 and 12 are another set.
  • Supplementary angles are angles which form a line and add to 180. If angle 1 + angle 2 = 180 and angle 2 = 129, then Angle 1+ 129 =180. Angle 1 must be 51 degrees.
  • Vertical angles are angles across a vertex. They are congruent. Example: Angle 2 and Angle 3 are both 129.

Using these relationships, the following angles have the following measures:

Angle 1 = 51

Angle 2 = 129

Angle 3 = 129

Angle 4 = 51

Angle 5 =51

Angle 6 = 129

Angle 7 = 129

Angle 8 = 51

Angle 9 = 51

Angle 10 = 129

Angle 11 = 129

Angle 12 = 51

A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for ever
Sphinxa [80]

Answer:

304\dfrac{4}{7}\ milliliters

Step-by-step explanation:

If there are 3 milliliters of compound A used for every 4 milliliters of compound B, then we can denote that we use 3x milliliters of compound A and 4x milliliters of compound B to get 533 milliliters of the drug. Thus,

3x+4x=533,\\ \\7x=533,\\ \\x=\dfrac{533}{7}\ milliliters.

Hence, a chemist must take

4\cdot \dfrac{533}{7}=\dfrac{2132}{7}=304\dfrac{4}{7}\ milliliters

of compound B.

Who knows how to do this I TRULY NEED HELP
zavuch27 [327]

Answer:

x = 10

Step-by-step explanation:

It's given in the question that both the traingles JCD & JKL are similar. So their ratio of corresponding similar sides will be proportional to each other.

=  >  \frac{JD}{JL} =  \frac{JC}{JK}  =  \frac{DC}{LK}

=  >  \frac{15}{50}  =  \frac{8 + x}{60}  =  \frac{DC}{LK}

=  >  \frac{15}{50}  =  \frac{8 + x}{60}

=  > 8 + x =  \frac{15 \times 60}{50}  = 18

=  > x = 18 - 8 = 10

Help first one gets brainllest
kherson [118]

Answer:

x = 1 \frac{1}{4}

Step-by-step explanation:

Expressing the diagram as an equation , that is

6x - 3 = 4 \frac{1}{2} = \frac{9}{2} ( multiply through by 2 to clear the fraction )

12x - 6 = 9 ( add 6 to both sides )

12x = 15 ( divide both sides by 12 )

x = \frac{15}{12} = \frac{5}{4} = 1 \frac{1}{4}
