Answer:

$\huge \boxed{1+(-3)=-2}$

Step-by-step explanation:

An arrow goes from 0 to 1.

So 0 + 1 or just 1.

An arrow goes from 1 to -2.

So 1 - 3 = -2.

1 moves 3 units to the left to -2.

$1+(-3)=-2$

Hi! i think the question represented by the number line is 1 minus -2 (so 1-2)

hope this helped!:)

2x - y2<br> Z-5<br> Evaluate when x = 2, y = 4<br> z=3

kolezko [41]

Answer:

Putting the value in x = 2 , y =4 in 2x - 2y we get,

2 × 2 - 4× 2= 4-8 = -4

Putting the value in z = 3 in z - 5 we get,

z - 5 = 3 - 5 = -2

Given that c=9, b=15, and C=29 degrees, find the measure of angle B

raketka [301]

Use the Sine Rule:-

b / sin B = c / sin C

15 / si n B = 9 / sin 29

sin B = 15* sin 29 / 9 = 0.8080

B = 53.90 degrees

Factor 3a^3 + 18a² + 8a + 48 completely.

fomenos

Answer:

(3a2 + 8) • (a - 6)

Step-by-step explanation:

STEP 1:

Equation at the end of step 1

(((3 • (a3)) - (2•32a2)) + 8a) - 48

STEP 2:

Equation at the end of step 2:

((3a3 - (2•32a2)) + 8a) - 48

STEP 3:

Checking for a perfect cube

3.1 3a3-18a2+8a-48 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 3a3-18a2+8a-48

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 8a-48

Group 2: -18a2+3a3

Pull out from each group separately :

Group 1: (a-6) • (8)

Group 2: (a-6) • (3a2)

-------------------

Add up the two groups :

(a-6) • (3a2+8)

Which is the desired factorization

Polynomial Roots Calculator :

3.3 Find roots (zeroes) of : F(a) = 3a2+8

Polynomial Roots Calculator is a set of methods aimed at finding values of a for which F(a)=0

It would only find Rational Roots that is numbers a which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 3 and the Trailing Constant is 8.

The factor(s) are:

of the Leading Coefficient : 1,3

of the Trailing Constant : 1 ,2 ,4 ,8

What is the solution to the system of equations? {10x^2 - y = 48 2y = 16x^2 + 48

julsineya [31]

A graph shows the solutions to be
(x, y) = (-6, 312) or (6, 312)

To solve algebraically, remove a factor of 2 from the second equation and use that expression to substitute for y in the first equation.
10x^2 -(8x^2 +24) = 48
2x^2 = 72
x = ±√(72/2) = ±6
y = 8*36 +24 = 312
