The expression 9x2 - 5x - 7 has ___ terms and a constant of ___.

elena55 [62]

Answer: first option 3, - 7

Justification:

1) Given expression:9x² - 5x - 7

2) Each monomial is a term.

The monomials are each combination of numbers and letters (coefficient, letters and exponents) separated of other monomials (terms) with a + or - operator.

3) Therefore, there are 3 terms which are:

9x²,
-5x, and
-7.

The polynomials with 3 terms are called monomials.

4) The monomial (term) withoud letter is the constant. In this case that is -7.

Find angle measures and arc measures

Vlad1618 [11]

Answer:

Step-by-step explanation:

a. We know that KH is a diameter of the circle and that along angles along it on either side adds up to 180° as it's a straight line.

-Therefore, we have that:

$m\angle a+ \angle GaH=180\textdegree\\\\\\m\angle a=180-35\\\\=145\textdegree$

Hence, the angle a is equal to 180°

b.We know that GJ is a diameter of the circle and that along angles along it on either side adds up to 180° as it's a straight line.

-Therefore, we have that:

$m\angle b+\angle GaK=180\textdegree\\\\m\angle b=180\textdegree -145\textdegree\\\\\\\\=35\textdegree$

Hence, the angle b is equal to 35°

Find the values of x and y

PSYCHO15rus [73]

Hi there!

So you're looking at an equilateral triangle, which is a big word that basically means all three sides are equal and all three angles are 60°.

Knowing that, the mesure of one side is 7, so necessarily the side "x" is also equal to 7.

So the value of x is : 7

And since all angles are of 60°, necessarily the angle "y" has an angle of 60°.

So the value of y° is : 60°

There you go! I really hope this helped, if there's anything just let me know! :)

What does the remainder theorem conclude given that f(x)/x+6 has a remainder of 14? Enter your answer by filling in the boxes.

musickatia [10]

Answer:

$f(-6)=14$

Step-by-step explanation:

According to the remainder theorem, if a function f(x) is divided by (x-a), then the remainder is defined by f(a).

It is given that $\dfrac{f(x)}{x+6}$ has a remainder of 14.

Here, the function f(x) is divided by (x+6). So, on comparing (x+6) and (x-a), we get

$a=-6$

So, by remainder theorem, remainder of $\dfrac{f(x)}{x+6}$ is f(-6).

Since the remainder is 14, therefore

$f(-6)=14$

Therefore, the answer for first blank is -6 and for second blank is 14, i.e., $f(-6)=14$ .
