What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
Answer:
x + 6
Step-by-step explanation:
Edit:
A moderator mentioned my answer had a mistake: turned out the question posted was incomplete. The complete question should read:
"
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
x – 6
x – 3
x + 1
x + 6
"
As shown in the same graph, f(x) cross the x-axis at x = -6, -3 and 0.
When a polynomial crosses the x-axis at x = a, (x - a) must be a factor.
So (x + 6), (x + 3) and x are factors of f(x).
Of the options, the correct answer is x + 6.

The diagonal of a quadrilateral shaped field is 24 m and the perpendiculars dropped on it from the remaining opposite vertices are 8 m and 13 m. Find the area of the field.
Put the values
Area:-
[tex]\\ \rm\Rrightarrow \dfrac{1}{2}(24)(8+13)[/tex]
[tex]\\ \rm\Rrightarrow 12(21)[/tex]
[tex]\\ \rm\Rrightarrow 252m^2[/tex]
Answer:
Step-by-step explanation:
Divide the quadrilateral field into two triangles by its diagonal.
Area of a triangle is given by the equation 1/2*base*height.
The top triangle's area = 1/2*24*13 = 156 m^2
The bottom triangle's area = 1/2*24*8 = 96 m^2
Combining, the area of the field = 156 + 96 = 252 m^2

I need help with 2(4/3)x8x15+280919 we couldn’t use calculator
Answer:
281,319.005
Step-by-step explanation:
Because 2 and 4/3=3 and 1/3
Because since the numerator= 4 and the denomeyer is 3 we can add another whole number so 2 and 4/3 can add whole so 2 + 1=3 wholes with 1 left over so 3 1/3.
Next we do 3 1/3 x 8 which=26.667 also known as 26 2/3
Because 2/3=66.667.
Next we so 26 and 2/3 x 15=400.005
And last 400.005 + 280,919=281,319.005

Which of the following is a factor of the expression 4x^2-2x-42?
Group of answer choices
2x-6
2x-7
x-3
4x-7
Answer:
[tex]4x ^{2} - 2x - 42 \\ 2(2 {x}^{2} - x - 21) \\ 2(2 {x}^{2} + 6x - 7x - 21) \\ 2(2x(x + 3) - 7(x + 3) \\ 2(2x - 7)(x + 3)[/tex]
Answer:
2x - 7
Step-by-step explanation:
4x² - 2x - 42 ( factor out 2 from each term )
= 2(2x² - x - 21) ← factor the quadratic
consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 21 = - 42 and sum = - 1
the factors are+ 6 and - 7
use these factors to split the x- term
2x² + 6x - 7x - 21 ( factor the first/second and third/fourth terms )
= 2x(x + 3) - 7(x + 3) ← factor out (x + 3) from each term
= (x + 3)(2x - 7)
then
4x² - 2x - 42 = 2(x + 3)(2x - 7) ← in factored form
with 2x - 7 as a factor
A line passes through the points (3,16) and (6,19). Write a linear function rule in terms of x and y for this line.
Answer:
y=1x+13
Step-by-step explanation:
First find the slope of the line. Slope is (y2-y1)/(x2-x1). Plug in 19 for y2, 16 for y1, 6 for x2, 3 for x1. So (19-16)/(6-3) is 3/3 or 1. The slope of the line is 1.
take the equation y=mx+b and plug 1 in for the slope (m). Then plug in one set of points. Using (3,16) into y=1x+b, 16=1(3) + b. Solve for b. B is 13. So the linear equation is y=1x+13.
rosa has a goal of running a total of 150 miles this month each day she ran for 6 miles . what expression could rosa use to determine how many miles she has left to run after running for d days
Answer:
miles left = 150 - 6d
Step-by-step explanation:
To create this expression, let 150 be the total number of miles she needs to run. If she runs 6 miles every day, the expression for miles she has left is the total miles - 6* how many days she has been running. Your final expression for miles she has left should be 150 - 6d.

Find the measure of the numbered angles for the given Isosceles Trapezoid
Answer:
Step-by-step explanation:
Hello!
This is a trapezoid. It is a quadrilateral with one pair of parallel sides while other sides are non-parallel. Here, the opposite angles are alternate, that is, they have together 180°.
Isosceles trapezoid
An isosceles trapezoid is a trapezoid with congruent base angles and congruent non-parallel sides. Here, the base angles are the same.
The line segment joining the midpoints of the parallel sides is perpendicular to the bases and the diagonals are the same in length.
Good luck:)
