A.
so we are given 2 points, (2,14) and (5,29)
we will use slope intercept form then convert to standard form
y=mx+b
m=slope
b=y intercept

first find slope
slope between the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
so
slope
(2,14) and (5,29)
slope=(29-14)/(5-3)=15/3=5
y=5x+b
find b
use a point
(2,14)
x=2 and y=14
14=5(2)+b
14=10+b
4=b

so
y=5x+4 is da equation
standard form, solve for ax+by=c
5x-y=-4




B.
that is solve for y and replace y with f(x)
y=5x+4
f(x)=5x+4


C.
one way is to subsitute points
when x=0, y=4
when x=1, y=9
graph theh points (0,4) and (1,9)
maybe graph the intercepts
x intercept is (-5/4,0)
y intercept is (0,4)

The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

<h3>What is residual value?</h3>

The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset.

Points and their residual values are shown in the table. A 3-column table with 5 rows.

  •  x                               1,     2,     3,     4,     5.
  •  y                               2,   3.5,   5,    6.1,    8.
  • Residual Value       -0.4, 0.7,  -0.2, -0.6   0

The simple regression line can be represented as,

\hat y=\alpha +\beta X+\hat e

Here α is the constant, β is the slope and <em>e </em>is the residue.

The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.

Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

HELP ME PLEASE I NEED HELP
anyanavicka [17]

Answer:

Step-by-step explanation:

This is a narrower-than-normal absolute value graph, which is a v-shaped graph. It's pointy part, the vertex, lies at (2, -3) and it opens upwards without bounds along both the positive and negative x axes. Therefore, as x approaches negative infinity, f(x) or y (same thing) approaches positive infinity. As x approaches positive infinity, f(x) approaches positive infinity.

What is the vertex of the absolute value function defined by ƒ(x) = |x + 5| + 7?
Temka [501]
To answer this, you need to know the general form of an absolute value function. the equation for this is f(x<span>) = </span>a|x<span> - </span>h<span>| + </span>k, and in this equation, the vertex is (h, k).

with that information, you can see that your vertex will be (-5, 7). you must take the negative for 5 because the general equation states that your h value is usually subtracted from x. to check your vertex, try plugging it into your general equation:
f(x) = a|x - (-5)| + 7
f(x) = a|x + 5| + 7 ... you see that this matches your given equation. this last part here was just to show why your 5 must be negative; your answer is bolded.
