Kelsey knit a total of 6 centimeters of scarf over 2 nights. After 4 nights of knitting, how many centimeters of scarf will Kelsey have knit in total? Assume the relationship is directly proportional.
Answer:
[tex]12[/tex] cm
Step-by-step explanation:
If Kelsey knit a total of [tex]6[/tex] cm of scarf over [tex]2[/tex] nights, then we know that she can knit [tex]\frac{6}{2}=3[/tex] cm each night. Therefore, after [tex]4[/tex] nights of knitting, Kelsey would have knit a total of [tex]3*4=12[/tex] cm of scarf in total. Hope this helps!
What is the vertex of this quadratic function.
(x-4)2 + 3 = 0
Answer:
(4, 3)
Step-by-step explanation:
Please use " ^ " to indicate exponentiation: (x-4)^2 + 3 = f(x) (which is not 0)
Comparing:
f(x) = (x - 4)^2 + 3 to the general vertex equation
f(x) = (x - h)^2 + k
tells us that the vertex is (h, k): (4, 3)

the angles of a triangle have measures of 78 degrees, 73 degrees, and 29 degrees. Which of the following be the measure of an exterior angle of a triangle?
A = 151 degrees.
B=141 degrees.
C=117 degrees.
D=112 degrees
Answer:
It's A.
Step-by-step explanation:
Extorior angles are 2 angles which match together which means 1 angle from outside the triangle matches with another angle in the triangle and form 180 degrees.
Use 180 and minus 78, 73 and 29 degrees separately. Do it until one of your answers match one of the options.
What is the range of the relation shown below?
{(-1, -3), (5, 5), (2, 2), (3, 0)}
The range of the function is given by R = { -3 , 5 , 2 , 0 }
What are domain and range?The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.
The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.
Given data ,
Let the function relation be represented as set A
Now , the value of set A is given by
Set A = { (-1, -3), (5, 5), (2, 2), (3, 0) }
Now , the range is the set of outputs of a relation
So , it is the set of all possible y values in the relation
Substituting the values in the equation , we get
So , the range of the relation is set R = { -3 , 5 , 2 , 0 }
Therefore , the value of R is { -3 , 5 , 2 , 0 }
Hence , the range of the function is { -3 , 5 , 2 , 0 }

2. Write a quadratic function that has -intercepts (- 3, 0) and (4, 0) and passes through the point (5, 8)
Answer:
[tex]f(x)=x^2-x-12[/tex]
Step-by-step explanation:
Quadratic Function
Standard Form of Quadratic Function
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
When the zeros of f (x1 and x2) are given, it can be written as:
f(x)=a(x-x1)(x-x2)
Where a is a constant called the leading coefficient.
We are given the two roots of f: x1=-3 and x2=4, thus:
f(x)=a(x+3)(x-4)
We also know that f(5)=8, thus:
f(5)=a(5+3)(5-4)=8
Operating:
a(8)(1)=8
Solving:
a=1
The function is:
f(x)=1(x+3)(x-4)
Operating:

5(x+8)= 8(x+1)
Answer:
x = [tex]\frac{32}{3}[/tex] (see below)
Step-by-step explanation:
First, use distributive property:
5 (x + 8) = 8 (x + 1)
5x + 40 = 8x + 8
Then, simplify the equation by combining like terms. You want to isolate the variable to one side of the equation so you can solve for it. Here what I'm talking about:
5x + 40 = 8x + 8
-5x -5x
-------------------------
40 = 3x + 8
-8 -8
-----------------
32 = 3x
Now, divide both sides by 3 to get the value of x:
3x = 32
x = [tex]\frac{32}{3}[/tex]
or
x ≈ 10.7
Answer:
x= 32/3
Step-by-step explanation:
5(x+8)= 8(x+1)
5x+40=8(x+1)
5x=40=8x+8
5x+40=8x+8
5x+40-40=8x+8-40
5x=8x-32
5x=8x-32
5x-8x=8x-32-8x
-3x=-32
-3x = -32
(Divide both by -3)
x=32/3
Solve the linear equation.

Write the equation of a line going through the points (4,2) and (7,-3).
Answer:
Equation of the straight line passing through the point ( 4,2) and (7,-3) is
5 x + 4y - 28=0
Step-by-step explanation:
Step(i):-
Given points are ( 4,2 0 and ( 7,-3)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-3-2}{7-4} = \frac{-5}{4}[/tex]
Step(ii):-
Equation of the straight line passing through the point ( 4,2) and
having slope m = [tex]\frac{-5}{4}[/tex]
y - y₁ = m( x- x₁ )
[tex]y - 2 = \frac{-5}{4} ( x-4)[/tex]
4( y -2) = -5( x-4)
4 y - 8 = - 5x +20
5x +4y -8 -20=0
5 x + 4y - 28=0
Final answer:-
Equation of the straight line passing through the point ( 4,2) and (7,-3) is
5 x + 4y - 28=0
3х - 2y = 11
Need the answer
Answer:
Step-by-step explanation:
Im assuming you the equation in terms of y, that's the conventional thing in high school math.
Add 2y to both sides:
3x = 2y + 11
Subtract 11 from both sides:
2y = 3x - 11
Divide both sides by 2:
y = (3x - 11)/2
