{\qquad\qquad\huge\underline{{\sf Answer}}}

Here's the explanation ~

Zeros or roots of a function is the value of independent variable (usually x - coordinate or absicca) where the value of dependent variable (y - coordinate or ordinate) is 0.

That is :

The point where it cuts the x - axis, it has an x - coordinate = -6

Therefore, we can conclude that The zero of given function is -6

Answer:

x = -6.

Step-by-step explanation:

It is where the graph cuts the x-axis  (where the function is zero).

That is -6.

Pls pls pls pls help, i will mark brainliest
kicyunya [14]

Answer:

B)  81°

Step-by-step explanation:

∡1 ≅ ∡5 because they are corresponding angles

∡5 ≅ ∡7 because they are vertical angles

therefore, ∡1 ≅ ∡7

since the angles are equal we can create the following equation:

3x + 18 = 2x + 39

x + 18 = 39

x = 21

∡7 = 2(21) + 39

∡7 = 42 + 39

∡7 = 81

ALGEBRA 1, SEMESTER 2- please help, im failing my class already
Maru [420]

Velocity is given as 80 feet per second, so replace V with 80.

The rocket is launched from the ground so the initial height is 0, so replace h with 0


The formula now becomes" h(t) = -16t^2 + 80t +0


To find the maximum we need to find the coordinates of the vertex by finding the axis of symmetry:

-b/2a = -80/(2*-16) = -80/-32 = 2.5

This represents the amount of time for the rocket to reach maximum height.

So we now replace t in the equation with 2.5 and solve for the height:

h(2.5) = -16(2.5)^2 + 80(2.5)

h(2.5) = 100


The maximum height is 100 feet

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -3x - 2

5x + 2y = 15

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                     5x + 2(-3x - 2) = 15
  2. Distribute 2:                          5x - 6x - 4 = 15
  3. Combine like terms:            -x - 4 = 15
  4. Isolate <em>x</em> term:                      -x = 19
  5. Isolate <em>x</em>:                               x = -19

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                    y = -3x - 2
  2. Substitute in <em>x</em>:                                     y = -3(-19) - 2
  3. Multiply:                                                y = 57 - 2
  4. Subtract:                                               y = 55
