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:

Step-by-step explanation:

for you to find x you first have to find the adjacent of the 45° angle you can do that by using the other triangle.using the sin ratio

sin60=opposite/hypotenuse

sin60=a/7√3

a=10.5

then after you have found the adjacent you can use the cos ratio

cos45=adjacent/hypotenuse

cos45=10.5/x

cos45x/cos45=10.5/cos45

x=14.849

which is the same as 21√2 over 2

I hope this helps

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).
