3. Write the following equation in slope intercept form: -2x + y = 9 A.) Y = -2x + 9 B.) Y = -2x – 9 C.) Y = 2x + 9 D.) Y = 2x –

Ira Lisetskai [31]

Hey! :)

So when we write something in slope intercept form, all we're doing is solving for y. So let's do that with this equation!

-2x + y = 9

add 2x to both sides

y = 2x + 9

So C is your answer.

Please let me know if you need anything further explained!

15 POINTS NEED FAST

Firlakuza [10]

Answer:

87 hits

Step-by-step explanation:

a = $\frac{h}{n}$

Where,

a is the batting average

h is the number of hits

n is the number of times at bat

Given;

a = 0.290

n = 300 times

Finding h;

0.290 = $\frac{h}{300}$

h = 0.290 × 300 = 87 hits

Sin (3x) dx = ? find the integral

AVprozaik [17]

Answer:

$\displaystyle \displaystyle \int {sin(3x)} \, dx = \frac{-cos(3x)}{3} + C$

General Formulas and Concepts:

Calculus

Antiderivatives - Integrals

Integration Constant C

Integration Property [Multiplied Constant]: $\displaystyle \int {cf(x)} \, dx = c \int {f(x)} \, dx$

Trig Integration: $\displaystyle \int{sin(x)} \, dx = -cos(x) + C$

U-Substitution

Step-by-step explanation:

Step 1: Define

$\displaystyle \int {sin(3x)} \, dx$

Step 2: Identify Substitution Variables

u = 3x

du = 3dx

Step 3: Integrate

[Integral] Rewrite: $\displaystyle \frac{1}{3}\int {3sin(3x)} \, dx$
[Integral] U-Substitution: $\displaystyle \frac{1}{3}\int {sin(u)} \, du$
[Integral] Trig Integration: $\displaystyle \frac{1}{3}[-cos(u)] + C$
[Expression] Multiply: $\displaystyle \frac{-cos(u)}{3} + C$
[Expression] Back-Substitute: $\displaystyle \frac{-cos(3x)}{3} + C$
