A coordinate plane with a line passing through (negative 4, 3), (0, 1), and (4, negative 1). Which linear function is represented by the graph? f(x) = –2x + 1 f(x) = –f(x) equals negative StartFraction one-half EndFraction x plus 1.x + 1 f(x) = f(x) equals StartFraction one-half EndFraction x plus 1.x + 1 f(x) = 2x + 1
Answer:
Step-by-step explanation:
If these 3 points are collinear, then we can find the slope of the linear function using any 2 of those points. Suppose we use (-4, 3) and (0, 1):
As we move from (-4, 3) to (0, 1), x increases by 4 and y decreases by 2. Hence, the slope of this lilne is m = rise/run = -2/4, or m = -1/2.
Using the slope-intercept formula y = mx + b and replacing y with 1, x with 0 and m with -1/2, we get:
1 = (-1/2)(0) + b, or b = 1. Then the desired equation is y = f(x) = (-1/2)x + 1

Classify the following angles.
13°
180°
Answer: The acute angle is the small angle which is less than 90°. If you choose the larger angle you. will have a Reflex Angle instead: The smaller angle is an Acute Angle, but the larger angle is a Reflex Angle.
Step-by-step explanation: An angle that is exactly 90 degrees is called a right angle. Angles greater than 90 degrees and less than 180 degrees are called obtuse angles. An angle that is exactly 180 degrees is called a straight angle. butt

The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month. What was the cost of his insurance before it increased?
Answer:
Considering is a compunded increase rate of the yearly car insurance fee and x is the initial value of the insurance fee then
x×(1.05)^12=$86.82
×=$86.82/(1.05)^12
The cost of his insurance before it increased is $82.48.
Here,
The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month.
We have to find the cost of his insurance before it increased.
What is Percentage?
A percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.
Now,
The cost of Mr. Patten’s car insurance increased by 5% to $86.82 per month.
Increased cost = [tex]\frac{5}{100} * 86.82 = 4.34[/tex]
Hence, The cost of his insurance before it increased = $86.82 - $4.34
= $82.48
So, The cost of his insurance before it increased is $82.48.

(1) has only one root if and only if [tex] b^2 - 4ac = 0[\tex]
(2) has two real roots if and only if [tex] b^2 - 4ac > 0[\tex]
(3) has two complex roots if and only if [tex] b^2 - 4ac < 0[\tex].
The number b^2 - 4ac is called the discriminant of the parable f(x).
From the graph we can see that the parable has only one root approx in x =1. Thus from point (1) we can conclude that the discriminant should be zero.
PD: a root of a polynomial f(x) is a number a such thast f(a) =0.
The answer is A.

(a) A dog owner records the weight of her dog. She finds that from the age of 20 weeks to the age of 48 weeks, the dog’s weight can be modelled by the equation w = 0.92t−0.15 (20 ≤ t ≤ 48), where w is the weight of the dog in kilograms, and t is the age in weeks.
(i) Find the weight of the dog at age 26 weeks according to this model.
(ii) Explain the inequality (20 ≤ t ≤ 48) that follows the equation.
(iii) Using algebra, calculate the age at which the dog’s weight is 40kg
(iv) Write down the gradient of the straight line represented by the equation w = 0.92t−0.15. What does this measure in the practical situation being modelled? (v) Either using Graphplotter or by hand, sketch the graph of w = 0.92t−0.15, putting w on the vertical axis and covering the time interval 20 ≤ t ≤ 48.
(vi) Explain why the model cannot be extended to model accurately the dog’s weight at birth
Answer:
(i)23.77kg
(ii)(ii) the inequality 20≤t≤48 means the weight of the dogs determined is for dogs that have the age of 20 weeks or less to the age of 48 weeks not more.
(iii)44 weeks
(iv)0.92
(v)Attached
(vi)The value of weight will be negative,which is unrealistic.
Step-by-step explanation:
(i)Given that the weight is modeled by the equation;
w = 0.92t−0.15 (20 ≤ t ≤ 48)
then substitute the value of t in the equation given that t=26 weeks
w=0.92*26-0.15=23.77kg
(ii) the inequality 20≤t≤48 means the weight of the dogs determined is for dogs that have the age of 20 weeks or less to the age of 48 weeks not more.
(iii)Apply the equation for weight
w=0.92t-0.15
40=0.92t-0.15
40+0.15=0.92t
40.15=0.92t
40.15/0.92=t
43.6⇒⇒44 weeks
(iv) Here , write the equation in slope intercept form of y=mx+c where m is the slope and c is the y-intercept
w=0.92t-0.15
y=mx+c
m=0.92
(v)sketch attached
(vi)
At birth, t=0 hence to find weight
w=0.92t-0.15
w=0.92*0-0.15
w=0-0.15
w=-0.15
The model cannot be extended to model accurately the dog's weight at birth because you will get a negative value for weight which is not realistic.
perfect square of 401
A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 401 is about 20.025. Thus, the square root of 401 is not an integer, and therefore 401 is not a square number.
Answer:
apparently In what I believe, 401 is not a perfect square mate!

401 is an odd number, because it is not evenly divisible by 2.

Laura has a backyard that she wants to renovate. Her
backyard is (x + 4) feet wide and (x + 6) feet long.
Laura wants to place a rectangular garden that is x
feet wide and (x + 2) feet long in the middle of her
backyard. Laura also wants to pour in concrete that
surrounds her garden in the backyard that will serve
as a walkway. What is the expression that represents
the area of the walkway? Refer to the diagram.
Answer:
Area of the walkway = 8x + 24
Step-by-step explanation:
Area of the total backyard = [tex]l\times b[/tex]
Area of total backyard = [tex](x+6)\times (x+4) = x^{2} +10x + 24[/tex]
Now, Area of the rectangular garden = [tex]l\times b[/tex]
Area of the rectangular garden = [tex]x (x+2) = x^{2} + 2x[/tex]
Now area of the walkway poured with concrete = Area of the backyard - Area of the rectangular garden
= [tex](x^{2} +10x +24) - (x^{2} +2x)[/tex]
= [tex]x^{2} + 10x +24 - x^{2} -2x[/tex]
= 8x + 24

Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Select three options. y = –Two-fifthsx – 2 2x + 5y = −10 2x − 5y = −10 y + 4 = –Two-fifths(x – 5) y – 4 = Five-halves(x + 5)
Answer:
Step-by-step explanation:
Two lines are perpendicular if the first line has a slope of [tex]m[/tex] and the second line has a slope of [tex]\frac{1}{-m}[/tex].
With this information, we first need to figure out what the slope of the line is that we're given, and then we can determine what the slope of the line we're trying to find is:
[tex]5x - 2y = -6[/tex]
[tex]-2y = -5x - 6[/tex]
[tex]y = \frac{5}{2}x + 3[/tex]
We now know that [tex]m = \frac{5}{2}[/tex] for the first line, which means that the slope of the second line is [tex]m = \frac{-2}{5}[/tex]. With this, we have the following equation for our new line:
[tex]y = \frac{-2}{5}x + C[/tex]
where [tex]C[/tex] is the Y-intercept that we now need to determine with the coordinates given in the problem statement, [tex](5, -4)[/tex]:
[tex]y = \frac{-2}{5}x + C[/tex]
[tex](-4) = \frac{-2}{5}(5) + C[/tex]
[tex]-4 = -2 + C[/tex]
[tex]C = -2[/tex]
Finally, we can create our line:
[tex]y = \frac{-2}{5}x - 2[/tex]
[tex]5y = -2x - 10[/tex]
[tex]2x + 5y = -10[/tex]
