Answer:
You can’t find the slope of a line if only given one point. If you had a visual representation of the line such as a graph or a table you could find a second point and then use the formula for slope, y = (y2-y1) / (x2-x1).
Imagine a single point on the xy graph. You could take a random point elsewhere from an infinite number of points and would be able to draw a line and find the slope. This means there could be an infinite number of different slopes for one point. One point on an unknown line is not enough information to determine the slope of its line without a graph or a table.

what is the domain of f in the equation f(x)=2(x-1)^2-4
Answer:
[tex](-\infty, \infty)[/tex]
Step-by-step explanation:
There are no restrictions on the possible values of [tex]x[/tex], because you can square any number.
Because [tex]x[/tex] can be anything, the domain is all reals or [tex]\boxed{(-\infty, \infty)}[/tex] which means [tex]x[/tex] can be any real number.

Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?
O -2(x - 2)2 = -8(7 + y)
O yx2-
o yo hx²-x-6
y=-2+ 28+4x
O y=2+28+4x
Answer:
-2(x-2)2=-8(7+y)
Step-by-step explanation:
Inverse means just -Lets solve afterwards
[tex]\\ \sf\longmapsto -2(x-2)2=-8(7+y)[/tex]
[tex]\\ \sf\longmapsto (-2x+4)2=-56-y[/tex]
[tex]\\ \sf\longmapsto -4x+8=-56-y[/tex]
[tex]\\ \sf\longmapsto -4x+y=-64[/tex]
[tex]\\ \sf\longmapsto 4x-y=64[/tex]
Answer:
-2(x - 2)2 = -8(7 + y)
Step-by-step explanation:
2(x - 2)2 = 8(7 + y)
(2x - 4)2 = 56 + y
4x - 8 = 56 + y
4x - 8 - 56 = y
4x - 64 = y
If option A
-2(x - 2)2 = -8(7 + y)
(-2x + 4)2 = - 56 - y
- 4x + 8 = - 56 - y
- 4x + 8 + 56 = - y
- 4x + 64 = - y
4x - 64 = y

Write the slope-intercept equation of the line passing through (3.4, 17.8) and (5.7, 64.7). Round the final slope and y-intercept to the nearest tenth in your answer. Show clear work.
Answer:
Answer:
y = 20.39x - 51.526
Step-by-step explanation:
y2 - y1 / x2 - x1
64.7 - 17.8 / 5.7 - 3.4
46.9/2.3
= 20.39
y = 20.39x + b
17.8 = 20.39(3.4) + b
17.8 = 69.326 + b
-51.526 = b

Answer:
x = 3/5
Step-by-step explanation:
5th root of Y is notated in exponential notation as Y^(1/5), which is Y to the one fifth (1/5) power.
So, the 5th root of 19^3 is (19^3)^(1/5) = 19^(3 * 1/5) = 19^(3/5), since (A^a)^b = A^(a*b).
Which statement correctly compares the function shown on this graph with
the function y = 4x + 2?
The statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'
What is rate of change of a function?The rate at which one quantity is changing with respect to another quantity.
For given question;
It is given a function y = 4x + 2
This function represents a line.
We have slope of the line = 4 and y - intercept = 2
We already know that the rate of change of line is given by its slope.
So, the rate of change of given function ;
y = 4x + 2 is 4.
The starting point of function f(x) is 2.
The graph of the line passing through points (-1, 1) and (0, 4)
So using slope formula,
m = (4-1)/ 0-(-1)
m = 3
So, the rate of change of function is 3.
The rate of change of function shown on the graph is smaller than the rate of change of function y = 4x + 2
Thus, the statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'
Hence, The correct answer is option (A)

I need to find y and z
for y-
24
45
27
135
for z-
135
98
82
90
Answer:
y = 27°z = 98°Step-by-step explanation:
The interior angle marked 5y is the supplement of the adjacent exterior angle marked 45°.
5y + 45° = 180°
5y = 135° . . . . . . . . subtract 45
y = 27° . . . . . . . . divide by 5
__
The sum of the interior angles of a pentagon is (5-2)(180°) = 540°.
90° +5y +z +82° +135° = 540°
Using y=27°, we can subtract 442° from both sides to get ...
z = 98°
_____
Additional comment
You might recognize that the downward-sloping diagonal sides of the figure are parallel, so z and 82° are consecutive interior angles, hence supplementary. This fact means you don't have to be concerned with the other three angles in the figure to find the value of z: 180° -82° = 98°.

An insurance agent earns a base salary of $28,000, a commission of 2% of sales, and receives an additional fee of $9 for each sale of an investment policy. The agent had total sales of $75,000 and 6 investment policies this month. Find the commission and fees earned. (There should be 2 separate answers)
Answer:
$54 for fees
$1500 for commission
$29554 in total
Step-by-step explanation:
They will have $28000 regardless.
The commission is 2% so you multiply 0.02 (which is equivalent to 2%) to $75000, so he earns $1500. He sold 6 sales so he you multiply 6 by $9 and you get $54.
I don't know exactly what your asking but
$54 for fees
$1500 for commission
$29554 in total
