I need help with this slope question grade 9
the slope is NEGATIVE 3/2
I really need help it's due today at 2:00
1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
A.f(–9) = 14
g(1) = 30
B.f(–9) = –78
g(1) = –11
C.f(–9) = –66
g(1) = 29
D.f(–9) = 8
g(1) = –80.75
2.Find the value of f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x3 – 24x .
A. f(–9) = 25
g(–1) = 21
B.f(–9) = –5
g(–1) = 20
C.f(–9) = 29
g(–1) = 26
D.f(–9) = 3
g(–1) = –27
Answer:
1. f(–9) = -66 , g( 1 ) = 27 (Please double-check your given options, there must have been a typographical error for Option C for g( 1 ) = 29). g( 1 ) is supposed to be 27.
2. Option A: f(–9) = 25, g(–1) = 21
Step-by-step explanation:
1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2
f(x) = 8x + 6
f(–9) = 8(-9) + 6 = -66
g(x) = 9x + 20x − 2
g( 1 ) = 9( 1 ) + 20( 1 ) − 2 = 27
None of the given choices were correct (unless there's a typo error for Option C — it's supposed to be g( 1 ) = 27 instead of 29?) because the correct answers are: f(–9) = -66 and g( 1 ) = 27
2. f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x³ – 24x
f(x) = –3x – 2
f(–9) = –3(–9) – 2 = 25
g(x) = 3x³ – 24x
g(–1) = 3(–1)³ – 24(–1) = 21
Therefore, the correct answer is Option A: f(–9) = 25, g(–1) = 21

bChoose the equation that represents the graph.
Oy = x - 3
Oy = -x + 3
Oy = -x-3
Oy = x + 3
The graph illustrates a linear function, because the graph is a straight line
The equation of the graph is (d) y = x +3
The points on the line are:
[tex](x_1,y_1) = (-3,0)[/tex]
[tex](x_2,y_2) = (0,3)[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x1, x2, y1 and y2
[tex]m = \frac{3-0}{0--3}[/tex]
Simplify
[tex]m = \frac{3}{3}[/tex]
Divide
[tex]m = 1[/tex]
The equation of the line is then calculated using the following formula:
[tex]y = m(x - x_1) + y_1[/tex]
Substitute values for m, x1 and y1
[tex]y = 1(x - -3) + 0[/tex]
Simplify
[tex]y = 1(x +3)[/tex]
Open bracket
[tex]y = x +3[/tex]
Hence, the equation of the graph is (d) y = x +3

Jackson deposits $4,200 in a savings account that pays 3.5% annual interest.What is the total value of the account after 10 years
Answer:
5924, 51
Step-by-step explanation:
X = 4200(1.035)^10
And put it in a calculator
The total value of the account after 10 years is $5,924.52.
Given that,
The deposited amount is $4,200.The rate of interest is 3.5%.And, the time period is 10 years.Based on the above information, the calculation is as follows:
[tex]= \$4,200 \times (1 + 3.5\%)^{10}[/tex]
= $5,924.52
Therefore we can conclude that the total value of the account after 10 years is $5,924.52.

if the gradient of a line is 2 and (7,2) is a point on the line, find it's equation
Answer:
y = 2x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c is the partial equation
To find c substitute (7, 2 ) into the partial equation
2 = 14 + c ⇒ c = 2 - 14 = - 12
y = 2x - 12 ← equation of line

How many numbers x between 1 and 100 (inclusive) have the property that x2+x3 is a perfect square?
(Please help. I'm suffering)
=========================================================
Explanation:
Factor the given expression
x^2+x^3
x^2*1+x^2*x
x^2(1+x)
x^2(x+1)
We end up with something where the factor x^2 is a perfect square regardless of whatever we replace x with from the set {1,2,3,...,99,100}.
In short, we don't need to worry about the x^2 portion.
--------------------
The only thing of importance is the x+1 factor.
The x+1 must be a perfect square so that the original expression is as well.
Let's say M is some perfect square between 1 and 100. That means M belongs to the set of values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100}
If we want M+1 to be a perfect square, then we'll need to subtract 1 from each item in that set above to counteract the "plus 1" in "M+1".
Subtract 1 from each item to end up with this modified set
{0, 3, 8, 15, 24, 35, 48, 63, 80, 99}
--------------------
Every item mentioned in that second set will make x^2+x^3 to be a perfect square.
For example, let's pick x = 15
x^2(x+1) = 15^2*(15+1)
x^2(x+1) = 15^2*16
x^2(x+1) = 15^2*4^2
x^2(x+1) = (15*4)^2
x^2(x+1) = 60^2
This confirms that x^2+x^3 is a perfect square for x = 15. I'll let you check the other values.
There are 10 values in the set {1^2,2^2,...,9^2,10^2} = {1,2,...,81,100}. There are also 10 values in the set {0,3,8, ..., 80, 99} we got earlier. The cardinality hasn't changed. However, we'll kick out 0 because it's not between 1 and 100. So we end up with 9 as our final answer.
--------------------
To summarize, there are 9 values of x that make x^2+x^3 a perfect square, where x is some whole number between 1 and 100 inclusive.

A car is 150 inches long. A truck is 60% longer than the car.
How long is the truck?
Answer: Therefore, the truck is 240 inches long.
Step-by-step explanation:
truck = 150 + 60% of 150
= 150 + 60/100 * 150
= 150+90
