The solution (4, 1) is in the solution is in the system
How to determine if the solution is in the system?From the question, we have the following parameters that can be used in our computation:
y = 1
y = -2x - 9
Substitute y = 1 in the equation y = -2x - 9
So, we have the following representations
1 = -2x - 9
Evaluate the like terms
So, we have
-2x = -8
Divide both sides by -2
x = 4
This means that the solution is (4, 1)
Hence. (4, 1) is in the solution is in the system

A pair of jeans at a local retail store has a cost of $32.00. If the sales tax is 5.3%, what is the total amount paid for the jeans?
The total amount that a customer will pay for the jeans is $33.696.
How to calculate the value?From the information given, pair of jeans at a local retail store has a cost of $32.00. If the sales tax is 5.3%,
The value of the sales tax will be:
= Sales percentage × Amount
= 5.3% × $32
= $1.696
The total amount paid will be:
= Cost + Tax
= $32 + $1.696
= $33.696

Rationalize denominators and tell which ones are negative.
The value cos(θ), sin(θ), tan(θ), csc(θ) and cot(θ) are 1/8, (-3√7)/8, -3√7, -(8√7)/21 and -√7/21 respectively
How to find the trigonometric ratio of the angle?Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.
Given that: sec(θ) = 8 and tan(θ) < 0. This implies:
cos (θ) = 1/8 and tan(θ) is negative. This means θ is quadrant 4
(Note: cos (θ) = 1/sec(θ) )
Using the given information, we can sketch the location of the angle θ in the quadrant (See the attached image).
Thus, we can calculate the value of side d using the Pythagoras theorem
d = √(8² - 1²) = √63 = 3√7
The side is -d = -3√7
Note: the side d is negative in the quadrant
Therefore:
cos(θ) = 1/sec(θ) = 1/8
sin(θ) = (-3√7)/8
tan(θ) = (-3√7)/1 = -3√7
csc(θ) = 8/(-3√7) = - (8√7)/21
cot(θ) = -1/(-3√7) = -√7/21

a fair coin is tossed five times, and each time the coin lands tails up. if the coin is then tossed 1990 more times, how many tails are most likely to appear for the 1990 additional tosses?
Probability of getting tails are most likely to appear for the 1990 additional tosses will be 1/32.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Please anyone I need and explanation and just h and c solving them and explaining how that it please.
Answer: h = 19, c = 132
Step-by-step explanation:
Oooh! This is a toughie!
Okay, first of all, there's a straight line on top. A straight line is 180 degrees.
This means we have to subtract 48 from 180.
180 - 48 = 132.
This means both a and b are 132.
F is equal to 151.
180 - 151 = e
e = 29
d = 29
g = 29
132 + 29 = 161
180 - 161 = 19
h = 19
19 + 29 = 48
180 - 48 = 132
c = 132

Write an equation in slope-intercept form of the line with the given
characteristics.
slope = 2/5
; passes through (–3, 1)
Answer:
The equation of the line in slope-intercept form is [tex]y=0.4x+2.2[/tex]
Step-by-step explanation:
The equation of the line in slope-intercept form can be calculated as follows ?
The first step is to find the slope-intercept form of the given line by the point-slope form formula as follows
[tex]y-y_{1}=m(x-x_{1})[/tex]
Where [tex]m[/tex] is the slope of the line
Write the given value of the slope
[tex]m=\frac{2}{5}[/tex]
Convert the value of the slope into decimal
[tex]m=0.4[/tex]
The second step is to substitute [tex]0.4[/tex] for [tex]m[/tex], [tex]1[/tex] for [tex]y_{1}[/tex], [tex]-3[/tex] for [tex]x_{1}[/tex] in the point-slope form formula
[tex]y-1=0.4(x-(-3))[/tex]
Take out the inner bracket on the right side of the equation
[tex]y-1=0.4(x+3)[/tex]
Expand the right side of the equation
[tex]y-1=0.4x+1.2[/tex]
Add [tex]1[/tex] to both sides of the equation
[tex]y-1+1=0.4x+1.2+1[/tex]
Simplify the equation
[tex]y=0.4x+2.2[/tex]
Hence the equation of the line in slope-intercept form is
[tex]y=0.4x+2.2[/tex]
