Answer with solution

adelina 88 [10]

In general, the scalar multiple of k times u, is this:

 $k\vec u = k(ux, uy)=(Kux,Kuy)$

So, here's how we find $3\vec v$

$3\vec v = 3 * (2,4) = (3*2,3*4) 

= (6,12)$

The answer is (6,12).

1.) What is the best approximation of the solution to the system to the nearest integer values?

melisa1 [442]

Part 1) we have

$5x+2y=16$ ------> equation A

$x+3y=12$

$x=12-3y$ ------> equation B

Substitute the equation B in equation A

$5[12-3y]+2y=16$

$60-15y+2y=16$

$13y=44$

$y=44/13=3.38$

Find the value of x

$x=12-3(44/13)=1.85$

the best approximation is the point $(2.3)$

therefore

the answer Part 1) is the option C

$(2.3)$

Part 2) we have

$y=-x-2$ ------> equation A

$y=3x+2$ ------> equation B

equate equation A and equation B

$-x-2=3x+2$

$4x=-4$

$x=-1$

Find the value of y

$y=-(-1)-2=-1$

the solution is the point $(-1,-1)$

therefore

the answer Part 2) is

$(-1,-1)$

What is the slope of the line that goes through the points (2,-1) and (6,1)

drek231 [11]

Answer: The slope is $\frac{1}{2}$ .

Step-by-step explanation:

1. You set up your Slope Formula $M=\frac{y2-y1}{x2-x1}$ .

2. Substitue your points into the formula. $M=\frac{1--1}{6-2}$ .

3. Once you substitute, you will solve the equation $M=\frac{2}{4}$ .

4. Simplify the equation if you have to $M=\frac{1}{2\\}$ .

∠A and ∠B are vertical angles. If ∠A=8x+14 and ∠B=2x+50, what is m∠B?

Maslowich

Answer:

∠B = 62°

Step-by-step explanation:

Because ∠A and ∠B are vertical angles they are equal hence we can write

∠A = ∠B

8x + 14 = 2x + 50

Now we have to solve for x

To do so, subtract 2x on both sides of the equation:

6x + 14 = 50

Now, subtract 14 on both sides of the equation

6x = 36

Now, divide 6 on both sides of the equation

x = 6

To find m∠B you have to you have to plug in x = 6 back into the ∠B equation

∠B = 2(6) + 50

∠B = 62°
