The value of y would decrease if x increases and the sum stays the same.

If the value of x increases by 4 and the sum is constant or the same, the value of y will decrease. Ex: if x=1 increase by 4 so, 5+y=13 then y=8,if x increase by 4, 9+y=13, then y=4.

Let v1=(2,-6) and v2=(-4,7)

seropon [69]

The magnitude of each vector is the Pythagorean sum of its components.

a. |v1| = √(2² + (-6)²) = √40 = 2√10

|v2| = √((-4)² + 7²) = √65

b. To make each vector into a unit vector, divide each component by the vector's magnitude.

u1 = v1/|v1| = (2/(2√10), -6/(2√10))

u1 = (√10/10, -3√10/10)

u2 = v2/|v2| = (-4/√65, 7/√65)

u2 = (-4√65/65, 7√65/65)

Sally begins hiking at an elevation of 224 feet. Then, she descends 131 feet and climbs 67 feet higher than her current position

Deffense [45]

Answer:

-3

Three feet below the initial elevation

Step-by-step explanation:

The initial elevation is 224 feet.

We take descent to be negative and ascent to be positive.

The numerical addition expression is

$224+-131+67+-163$

We simplify this to obtain:

$224-131+67-163=-3$

The negative sign means Sally is 3 feet below his initial elevation

Write the standard form of the line that contains a slope of 1/2 and y-intercept of 3. Include your work in your final answer. T

nata0808 [166]

Answer:

2y-x=6

Step-by-step explanation:

Standard form is ax+by=c.

Slope form : y=mx+n where m is slope n-y intercept.

First we write in slope form

$y=\frac{1}{2}x+3$

Now we can multiply both sides by 2.

2y=x+6

Subtract for each side x

2y-x=6
