Answer:

y = 3x + 18

Step-by-step explanation:

First find m.

m = 0 + 9 / -6 + 9

= 9 / 3

= 3

Now, substitute m, x and y to find b.

0 = 3(-6) + b

b = 18

So, equation is :-

y = 3x + 18

Imagine that you need to compute e^0.4 but you have no calculator or other aid to enable you to compute it exactly, only paper a

UNO [17]

Answer:

upper bound for the error, | Error | ≤ 0.0032

Step-by-step explanation:

Given the data in the question;

$e^{0.4$ < e < 3

Using Taylor's Error bound formula

| Error | ≤ ( m / ( N + 1 )! ) $| x-a |^{N+1$

where m = $| f^{N+1 }(x) |$

so we have

| Error | ≤ ( 3 / ( 3 + 1 )! ) $|$ -0.4 $|$ ⁴

| Error | ≤ ( 3 / 4! ) $|$ -0.4 $|$ ⁴

| Error | ≤ ( 3 / 24 ) $|$ -0.4 $|$ ⁴

| Error | ≤ ( 0.125 ) $|$ -0.0256 $|$

| Error | ≤ ( 0.125 ) 0.0256

| Error | ≤ 0.0032

Therefore, upper bound for the error, | Error | ≤ 0.0032

A.The y-intercept of the function is 3.

Marrrta [24]

Answer:

D. The slope of the function is positive.

Step-by-step explanation:

I think the best thing to start with is the slope. Lets figure it out using the slope formula, (y2-y1)/(x2-x1).

Using the points, (-4, -7) and (-3, -4),

(-4 - (-7)) / (-3 - (-4))

= 3 / 1

= 3

Right off the bat, you can see that C is incorrect.

Lets go through the other choices and check now.

Using our slope, lets write an equation in the slope intercept form.

y = -3x + b (derived from y=mx+b)

Now, lets plug in a point (let's say, (-4,-7)) to verify if 3 really is the y intercept.

-7 = 3(-4) + b

-7 = -12 +b

5 = b

Since 3 is not equal to 5, A is incorrect. That leaves us with choice B and D.

We know that the x-intercept is found as (0, a), meaning that this x intercept is (0, 5/3). Let's plug it into the equation!

0 = 3(5/3) + 5

0 = 5 + 5

0 = 10

Since this is obviously incorrect, our answer is D, the slope of the function is positive. Let me know if you have any other questions.
