Answer:

He made a mistake in the second line.

Step-by-step explanation:

He factored out x out of 6-2x and 5+4x, which is not possible because there is not an x in both 6 and 5.

11 15 15/x

Jonah spent the cost of a movie ticket and split the cost of popcorn, so this needs to be represented by a " + ". Jonah just buy one piece tickets, so 11 is tickets price. We know Jonah's costs represented by the expression 11+15/x, "x" on behalf of the number of he and his friends, so 15 is the price of popcprn. 15/x means one person's money for the poopcorn, including Jonah.

Answer:

c = 7

d = 5

Step-by-step explanation:

Notice that in the first expression, x^c is inside a square root, and only perfect squares can be extracted from it. On the simplified form shown on the right hand side, we have x^3 outside the root and a single "x" left inside. In order for such to happen (x^3 get outside the root) there must have been an x^6 inside the square root. This together with the sole "x" that was left in the root, totals seven factors of x that should have been originally inside the square root:

x^6 * x = x^7 therefore c was a "7"

In the second expression we have a CUBIC root, so only perfect cubes can get extracted from it. Since there is one factor "x" shown in the simplified form (right hand side of the equal sign), that means that it must have been an x^3 (perfect cube) apart from the x^2 that was left inside the root. This makes the original power of x to be a 3 + 2 = 5.

Therefore d = 5

The expression $-2\vec C+6\vec D$ in the ordered pair notation is (16,-16).

The vector components of a vector are represented as the ordered pair of its x and y components.

For example, if a vector has x - component 'a' and y- component 'b' , then the ordered pair notation for the vector is (a, b), where the vector is $a \vec i+b \vec j$ .

Now the vector C has its x- component = -2

y- component of C = -1

Therefore, ordered pair notation of C = (-2, -1)

x- component of D = 2

y-component of D = -3

Therefore, ordered pair notation of D = (2,-3)

So the expression $-2\vec C+6\vec D$ = -2 (-2,-1) +6 (2,-3) = (4,2) + (12, -18)

= (16, -16) in the ordered pair notation.

That is, the vector $\bold {-2\vec C+6\vec D}$ is a vector with x-component 16 and y-component -16.

Equation of the line if (-4,1) and m=3

galben [10]

Answer:

y=3x+13

Step-by-step explanation:

y=mx+b

y=3x+b

so now we plug in the coordinates

1=3(-4)+b

1=-12+b

b=13
