Construct a linear function that has a slope of -3 and passes through the point (−2,3)
Answer:
f(x) = -3x - 3
Step-by-step explanation:
you can use the point-slope form to help you.
[tex]y - y_{1} = m (x - x_{1} )[/tex] m = slope and [tex](x_{1} , y_{1}) = (-2, 3)[/tex]
So, y - 3 = -3(x + 2)
y - 3 = -3x - 6
y = -3x - 3 or f(x) = -3x - 3
[tex]f(x) = -3x - 3[/tex]You can use the standard form y = mx + c to build that linear relationship.
Thus, the needed linear function is: [tex]f(x) = -3x -3[/tex]
Given that:The line has slope of -3The line passes through (-2,3)To find:The linear function
Relation between linear function and straight line:A linear function of two variables is always an equation of a straight line and can be converted into standard form y = mx + c (assuming m and c to be finite constants and x and y are variables).
m denotes slope of this line and c denotes intercept on y axis by this line.
If linear function is not of two variables, then we can take the output f(x) as value of second variable.
Since the slope is already given, thus, we have the equation as:
y = -3x + c
Now, since the line passes through (-2,3), thus it must satisfy the equation since the point is member of the family of points who constitute this line(and since the equation shows family of such points, thus the point should satisfy the equation).
Thus,
[tex]y = -3x +c|{(x,y) = (-2,3)}\\ 3 = -3 \times -2 + c\\ 3 = 6 + c\\ c = 3 - 6\\ c = -3[/tex]
Thus, we have the equation of the straight line in consideration as:
y = -3x -3
y is function of x, thus can be rewritten as [tex]f(x) = -3x -3[/tex] (assuming f doesn't represent any other function as we can't use used symbols in a context to prevent ambiguity)
Thus, the needed linear function is: [tex]f(x) = -3x -3[/tex]

y/8 = 40, y = 5
is this correct? yes or no
Answer: No, the correct answer is 320.
Step-by-step explanation: To solve for Y, simplify both sides of the equation, then isolate the variable.
Step 1: Multiply both sides by 8.
[tex](\frac{y}{8} )\times(8)=(40)\times(8)=320[/tex]
Therefore, your answer is incorrect, the correct answer is 320.
Which of these functions is not a linear function? Why?
f(x)=x-x
f(x)=3x
f(x)=x3
f(x)=23x-2
how am i supposed to know-
Answer:
f(x)=x3
Step-by-step explanation:
If you meant f(x)=x3 by f(x)=x^3 then that would be a cubic equation and not linear?

Match, each of the given measures to the correct side or angle 11, 7.5, 13
Write the equation of a line through (3,1), parallel to y = x + 1
y=-2/3x - 1
y=-5/3x -2/3
y= 2/3 - 1
y=-x-2/3
Answer:
The answer is C ( y= 2/3x - 1 )
Step-by-step explanation:
Equation Formula : y - y1 = m ( x - x1)
y - 1 = 2/3 ( x - 3 )
y - 1 = 2/3x - 2
y = 2/3x - 2 + 1
y = 2/3x - 1

An airplane climbs at an angle of 16° with the ground. Find the ground
distance the plane travels as it moves 2500 m through the air.
Please help me with this!
Answer:
2403.2
Step-by-step explanation:
We get the length of the hypotenuse, and the base angle. To find the length of the base, we use the cosine of 16° since it is equal to the adjacent side length/ hypotenuse side length or cos 16°= x/2500. The isolate x by multiplying both sides by 2500. The cos 16° is around 0.96126, multiplied by 2500 (cos 16°(2500)) = 2403.1

Type B blood donors ≈ 16
b. No. of blood donors without blood type O =
Those without blood type O ≈ 80
c. Find the number of people that had type AB:
Type AB = ≈ 6. This is less than 10 donors.
Therefore, blood type AB had less than 10 donors.
