Measure the lengths of the following segments in inches.
which number is a zero of f(x) = 2x (x + 7) ( x-4)
Answer:
0, -7, 4
Step-by-step explanation:
Zeros of a function are values that make the function = 0
So, f(x) = 2x(x + 7)(x - 4) = 0
x = 0 or x + 7= 0 or x - 4 = 0
x = -7 x = 4
Note: If you were to graph f(x), the graph would intercept the x-axis at 0, -7, and 4

. Question Category: Solving Quadratic Equations by Factoring Select the correct answer. Find the solution(s) for x in the equation below. x^2 + 10x + 21 = 0 x = 3; x = -7 x = -3; x = -7 x = 3; x = 7 x = -3; x = 7
Answer:
x= -7 and x= -3
Step-by-step explanation:
(x+7)(x+3)=0 (Think about the numbers that will add to 10 and multiply to 21)
x= -7 and x= -3
Answer:
x = −3 or x = −7
Step-by-step explanation:
Let's solve your equation step-by-step.
x^2 + 10x + 21 = 0
Step 1: Factor left side of equation.
(x+3) (x+7) = 0
Step 2: Set factors equal to 0.
x + 3 = 0 or x + 7 = 0
x = −3 or x = −7

The measure of one interior angle of a parallelogram is 50 degrees more than 4 times the measure of another angle
The measure of the smaller interior angle is
and the measure of the larger interior angle is?
Answer:
smaller ∡ = 26°
larger ∡ = 154°
Step-by-step explanation:
opposite angles are congruent
adjacent angles are supplementary
in this problem, the angles are supplementary
'x' = measure of smaller angle
x + 50 + 4x = 180
5x = 130
x = 26
The given information and the relationship between the angles of a
parallelogram can be used to find the interior angles.
The measure of the smaller angle is 26°The measure of the larger angle is 154°Reasons:
A property of a parallelogram is that the diagonally opposite angles are
equal, and the adjacent angles are supplementary.
Therefore, two of the four interior angles of a parallelogram are equal.
Let x and y represent the two angles of different measure in the
parallelogram
y = 4·x + 50°
y + x = 180°
Which gives;
y = 180° - x
Therefore;
180° - x = 4·x + 50°
180° - 50° = 4·x + x
130° = 5·x
x = 130° ÷ 5 = 26°
x = 26°y = 4 × 26° + 50° = 154°
y = 154°Therefore;
The measure of the smaller interior angle, x = 26°The measure of the larger interior angle, y = 154°Learn more about the properties of a parallelogram here:

A rectangle has a length of 4 meters. The width is 2 meters more than the length. Work out the area.
Answer:
24 m^2
Step-by-step explanation:
Given data
Length= 4 meters
Width= 2+4= 6 meters
We know that the expression for the area of a rectangle is given as
A= Lenght* Width
A= 4*6
A= 24m^2
Hence the area is 24 m^2

Answer:
[tex]y = \frac{1}{2} x- 4[/tex]
Step-by-step explanation:
You can solve this by saying:
[tex]\Delta y = s \Delta x[/tex]
so in this case we have
[tex]y - (-2) = \frac{1}{2}(x- 4)\\[/tex]
Now we can simply solve for y:
[tex]y + 2 = \frac{1}{2} x- 2\\y = \frac{1}{2} x- 4[/tex]

find an ordered pair of 5x + y = 3
Answer:
Step-by-step explanation:
Find an ordered pair that satisfies the equation 5x + y = 3.
There are infinitely many ordered pairs that satisfy this equation.
If we were to choose y = 0, then 5x = 3, and x = 3/5, leading to the ordered pair (3/5, 0).
If we were to choose x = 1, then 5(1) + y = 3, or y = -2. The ordered pair would be (1, -2).
And so on.

Which statement about f(x) = x^2 + 16x + 3 is true
A. The function has a maximum value of 3
B. The function has a maximum value of 16
C. The function has a minimum value of -8
D. The function has a minimum value of -61
Answer:
D
Step-by-step explanation:
Given a quadratic function in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
• If a > 0 then minimum value
• If a < 0 then minimum value
For
f(x) = x² + 16x + 3
a = 1 > 0 then f(x) has a minimum value
The minimum is the value of the y- coordinate of the vertex.
The x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
Here a = 1 and b = 16 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{16}{2}[/tex] = - 8
To find the y- coordinate of the vertex, substitute x = - 8 into f(x)
f(- 8) = (- 8)² + 16(- 8) + 3 = 64 - 128 + 3 = - 61
Thus the function has a minimum value of - 61 → D
