What is the product? (x-5)(2x+3x-1)
Firlakuza [10]
I assume the first term of the trinomial is 2x^2, and you left out the exponent.

Multiply each term of the binomial by each term of the trinomial.
Then collect like terms.

(x - 5)(2x^2 + 3x - 1) =

= x * 2x^2 + x * 3x + x * (-1) - 5 * 2x^2 - 5 * 3x - 5 * (-1)

= 2x^3 + 3x^2 - x - 10x^2 - 15x + 5

= 2x^3 - 7x^2 - 16x + 5

What is an equation of the line that passes through (2,2) and is parellel to the line y=7x
laila [671]

Answer:

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

Step-by-step explanation:

Given:

a line y=7x

To Find:

Equation of line passing through ( 2, 2) and is parellel to the line y=7x

Solution:

y=7x     ...........Given

Comparing with,

y=mx

Where m =slope

We get

Slope = m = 7

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.

Now the equation of line in slope point form given by

(y-y_{1})=m(x-x_{1})

Substituting the points and so we will get the required equation of the line,

(y-2)=7(x-2)=7x-14\\\\y=7x-12......Equation\ of\ line

Therefore, equation of the line that passes through (2,2) and is parellel to the line y=7x is y=7x-12

Please help asap, how do I find the missing variables? (Trigonometry)
Georgia [21]

Answer:

x = 5.333 , y= 9.620764575

Step-by-step explanation:

sin(29)/x = sin(90)/11

x = 11* sin(29)/sin(90)

x = 5.333

(5.333)^2 + y^2 = 121

y^2 = 121 - (5.333)^2

y= 9.620764575
