Step-by-step explanation:

Hey There!

To solve this problem we have to combine like terms

$7x^3-6x^3=x^3\\6x^2-8x^2=-2x^2\\-5x+10x=5x\\5-7=-2$

So our answer would be

$x^3-2x^2+5x-2$ (b)

What are the solutions of 3x2 + 14x + 16 = 0?

nevsk [136]

Good evening ,

Answer:

x = StartFraction negative 8 Over 3 EndFraction, –2

Step-by-step explanation:

3x² + 14x + 16 = 0

3x² + 6x + 8x + 16 = 0

(3x² + 6x) + (8x + 16) = 0

3x(x+2) + 8(x+2) = 0

(x+2)(3x+8) = 0

x = -2 , x = -8/3.

Write the following inequality in slope intercept form 5x-5y

IceJOKER [234]

Slope intercept form is written as y=mx+b where m is the slope and b is the y-intercept.

So first you need to put it in as y=5x-5y, and turn it into slope intercept form, which will be y=5/6x. Here are the steps:

y=5x-5y

Add 5y to both sides

y+5y=5x-5y+5y

Simplify

6y=5x

Divide both sides by 6

6y/6=5x/6

Simplify

y=5/6x

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

Okie help help math math math

liraira [26]

Answer:

$\displaystyle y = -3x + 9$

Step-by-step explanation:

First, find the rate of change of the line:

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}$

_______________________________________________

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:

$\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}$

I am joyous to assist you at any time.

Law of Sines: $\displaystyle \frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}$

A, B, C are angle measures
a, b, c are leg lengths

Step-by-step explanation:

Step 1: Identify

A = 27°, a = 11

B = x°, b = 15

Step 2: Solve for x

Substitute [LOS]: $\displaystyle \frac{sin(27^{\circ})}{11} =\frac{sin(x^{\circ})}{15}$
Cross-multiply: $\displaystyle 11sin(x^{\circ}) = 15sin(27^{\circ})$
Isolate x term: $\displaystyle sin(x^{\circ}) = \frac{15sin(27^{\circ})}{11}$
Isolate x: $\displaystyle x = sin^{-1}(\frac{15sin(27)}{11})$
Evaluate: $\displaystyle x = 38.2488 ^{\circ}$
Round: $\displaystyle x \approx 38.2 ^{\circ}$
