Answer:
Y=x+6
Step-by-step explanation:
to find out the slope you use the equation y2-y1/x2-x1. When you plug in the coordinates it will look like 7-2/1-(-4) and this is equal to 5/5 which can be simplified to 1. So the slope is 1! Now to find the y intercept you have to do b=y1-m*x1! If you plug into the coordinate it will be b=2−(1)⋅(−4) which is equal to 6. Then to construct out equation of the line it will be y=mx+b so now we plug in the slope and the y intercept so that the equation would be y=x+6

What is the range of the function graphed below?
Answer:
-3 < y ≤ 3
General Formulas and Concepts:
Algebra I
Range is the set of y-values that are outputted by function f(x)Step-by-step explanation:
According to the graph, our y-values span from -3 to 3. Since -3 is an open dot, it is exclusive from the range. Since 3 is a closed dot, it is inclusive in the range:
-3 < y ≤ 3 or (-3, 3]

Answer:
x = 44
y = 22
Step-by-step explanation:
✔️Find x:
Reference angle = 60°
Hypotenuse = x
Opposite side length = 22√3
Applying the trigonometric FUNCTION, SOH, we have:
Sin 60 = opp/hyp
Sin 60 = (22√3)/x
x × Sin 60 = 22√3
x = (22√3)/Sin 60
x = (22√3)/(√3/2) (sin 60 = √3/2)
x = 22√3 × 2/√3
x = (22√3 × 2) / √3
x = (44√3) / √3
x = 44
✔️Find y:
Reference angle = 60°
Hypotenuse = x = 44
Adjacent length = y
Applying CAH, we have:
Cos 60 = adj/hyp
Cos 60 = y/44
44 × Cos 60 = y
44 × ½ = y (cos 60 = ½)
22 = y
y = 22
Answer:
x=44,y=22
Step-by-step explanation:
sin 60=22√3/x
x=22√3/sin60=44
sin30=y/x
y=sin30×44=22

Parameter and StatisticWe are told that;
Population mean diameter; μ = 2.5003 cmSample Mean diameter; x-bar = 2.5009 cmNow, a parameter is defined as any measured quantity of a statistical population that describes an aspect of the population, such as a mean or standard deviation. These parameters are usually those that define the population such as population mean and population standard deviation.
However, the statistic is the number that describes a sample e.g, sample mean and sample standard deviation.

Given
mZAOC = 104°
mZAOB = 7x + 30°
mZBOC = 9x + 42°
Find mZBOC:
Answer:
The answer is 60°
Step-by-step explanation:
From looking at the problem we know that mZAOB and mZBOC make up angle mZAOC.
We also know that mZAOC is 104°
This means that the two other angles have to make up 104°
To figure out mZBOC,
First, you can subtract 30 and 42 from 104.
We do this because it allows us to focus on the variables.
104-30-42=32
Next, we can look at the variables and the coefficients and see that in order for 7x and 9x to make 32, x has to equal 2.
7(2)+9(2)=32
Now that we know what x equals we can substitute it into the equation for mZBOC.
9x + 42°
9(2) + 42°
60°
Thus, mZBOC equals 60°

Complete the equation of the line through (1,4) and (2, 2).
Answer:
The equation is
[tex]y = - 2x + 6[/tex]
Step-by-step explanation:
First we find the measure
[tex]m = \frac{4 - 2}{1 - 2} = - 2[/tex]
Then the equation is
[tex]y = - 2x + c[/tex]
To find C we can usw any point
Then
[tex]2 = - 2 \times 2 + c \\ c = 6[/tex]
Then the equation is
[tex]y = - 2x + 6[/tex]

function of time (in seconds) after Cassie hit it.
MARK BRAINLIEST
Answer:
your answer will be (0,25)
Step-by-step explanation:
have a nice day and good luck with your test ^_^
The point that corresponds to the ball's maximum height on the graph is (4, 80).
How to know if a point lies in the graph of a function?All the points (and only those points) which lie on the graph of the function satisfy its equation.
Thus, if a point lies on the graph of a function, then it must also satisfy the function.
Cassie hit a golf ball.
The function f models the height of the ball above the ground (in meters) as a function of time (in seconds) after Cassie hit it.
We can see from the graph that the highest point the ball could reach is 80 units.
Therefore, The point that corresponds to the ball's maximum height is (4, 80).

can someone help me on this. i dont understand it at ALL. please du~mb it down beacuase i am not smart at all.
Answer:
So basically you have to create a set of coordinates like (3,2) to create a linear function. Make sure to make a linear equation and represent it through a graph or table. Then take its coordinates.
An example is the table I attached. It is a linear function.
y = 4x is the linear equation.
(2,8) is the coordinate.

The least common denominator for the function [tex]\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}[/tex] is (x -2).
What is least common denominator?The least common multiple of a group of fractions' denominators is known as the lowest common denominator, or Least Common Denominator.
Calculation for the least common denominator:
Consider the given expression,
[tex]\frac{11x}{x^{2} +4x-12} -\frac{7}{2x^{2} -4x}[/tex]
Further simplifying the equation by factorisation of the denominator part
= [tex]\frac{11x}{x^{2} +6x-2x-12} -\frac{7}{2x(x -2)}[/tex]
= [tex]\frac{11x}{(x+6)(x-2)} -\frac{7}{2x(x -2)}[/tex]
= [tex]\frac{1}{x-2}[/tex]×[tex][\frac{11x}{(x+6)} -\frac{7}{2x}][/tex]
Therefore, from the above result, it is found that (x-2) is the least common denominator that can be taken.
