PLEASE HELP ME FAST!! I am close to a 100 so please don't give me a wrong answer.
timofeeve [1]

Answer:

y = 8x

Step-by-step explanation:

1. First, we need to know what slope-intercept form is. The slope-intercept form of any linear equation is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. To find the slope, let's take the two points (0,0) and (10,80) and plug their values into this formula: \frac{y_2-y_1}{x_2-x_1}

  • \frac{80-0}{10-0}
  • \frac{80}{10}
  • 8\\

3. Now that we know our slope, our equation should look like this so far: y = 8x + b.

4. Since b is the y-intercept, we can say that b = 0 because the line intersects with the y-axis at (0,0).

5. Therefore, we get an equation of y = 8x or y = 8x + 0.

Under his cell phone plan, Justin pays a flat cost of $56 per month and $5 per
Yuliya22 [10]

Answer:

Step-by-step explanation:

The inequality Equation =

42 + 5x < 60

To stay within her budget of less than $60 she must use less than 3.6 Gigabytes

Step-by-step explanation:

Under her cell phone plan, Brooklyn pays a flat cost of $42 per month and $5 per gigabyte. She wants to keep her bill under $60 per month.

Let the number of gigabytes = x

Under $60 means less than $60

The inequality =

$42 + $5×x < $60

42 + 5x < 60

Solving for x

42 + 5x < 60

5x < 60 - 42

5x < 18

x < 18/5

x < 3.6 Giga bytes

Hence, to stay within her budget of less than $60 she must use less than 3.6 Gigabytes

Which choice shows the sum of the two vectors&lt;-2 ,0&gt; and &lt;4,-5&gt; written as an ordered pair
umka21 [38]

Answer:

B. <2,-5>

Step-by-step explanation:

We are given the vectors,

u = <-2,0> and v = <4,-5>

It is required to find the sum of the vectors i.e. u + v.

So, we have,

u + v = <-2,0> + <4,-5>

i.e. u + v = < -2+4 , 0-5 >

i.e. u + v =  <2,-5>

Thus, the sum of the vectors written as ordered pairs is <2,-5>.

Hence, option B is correct.
