1) write the equation of the
Helen [10]

Answer:

y=3/2x-2

Step-by-step explanation:

Find the slope first:

m=\frac{y_{2-y_{1} } }{x_{2}-x_{1}  } =\frac{1-(-2)}{2-0}=\frac{3}{2}

Then solve for y-intercept:

y=\frac{3}{2}x+b\\-2=\frac{3}{2}(0)+b\\-2=b

Now, write out your complete equation:

y=3/2x-2

Find x. A. 21√2 B. 7 C. 21√3 over 2 D. 21√2 over 2
kkurt [141]

Answer:

D

Step-by-step explanation:

<em>for </em><em>you </em><em>to </em><em>find </em><em>x </em><em>you </em><em>first </em><em>have </em><em>to </em><em>find </em><em>the </em><em>adjacent</em><em> </em><em>of </em><em>the </em><em>4</em><em>5</em><em>°</em><em> </em><em>angle </em><em>you </em><em>can </em><em>do </em><em>that </em><em>by </em><em>using</em><em> </em><em>the </em><em>other </em><em>triangle.</em><em>u</em><em>s</em><em>i</em><em>n</em><em>g</em><em> </em><em>the </em><em>sin </em><em>ratio</em>

<em>sin60=</em><em>opposite</em><em>/</em><em>hypotenuse</em>

<em>sin60=</em><em>a/</em><em>7</em><em>√</em><em>3</em>

<em>a</em><em>=</em><em>1</em><em>0</em><em>.</em><em>5</em>

<em>then </em><em>after </em><em>you </em><em>have </em><em>found</em><em> </em><em>the </em><em>adjacent</em><em> </em><em>you </em><em>can </em><em>use </em><em>the </em><em>cos </em><em>ratio</em>

<em>cos45=</em><em>adjacent/</em><em>hypotenuse</em>

<em>cos45=</em><em>1</em><em>0</em><em>.</em><em>5</em><em>/</em><em>x</em>

<em>cos45x/</em><em>cos45=</em><em>1</em><em>0</em><em>.</em><em>5</em><em>/</em><em>cos45</em>

<em>x=</em><em>1</em><em>4</em><em>.</em><em>8</em><em>4</em><em>9</em>

<em>which </em><em>is </em><em>the </em><em>same </em><em>as </em><em>2</em><em>1</em><em>√</em><em>2</em><em> </em><em>over </em><em>2</em>

<em>I </em><em>hope</em><em> this</em><em> helps</em>

Simplify the given polynomial and use it to complete the statement.
Lorico [155]

Answer:

1)  2x^{2}+13

2) Option C.

3) Option B.

Step-by-step explanation:

1. You must apply the Distributive property as following:

(-5x^2-2x+4)+(8x^2-x-1)-(x^{2}-5x+2x-10)

2. Now, you must distribute the negative sign, then you have:

-5x^2-2x+4+8x^2-x-1-x^{2}+5x-2x+10

3. Finally, you must add the like terms. Then you obtain the polynomial:

2x^2+13

4. By definition, a polynomial that has two terms is classified as a binomial. Therefore, the answer is the option C.

5. The degree of a polynomial is determined by highest exponent of the variable. So, it is a polynomial of degree 2 (option B).
