Answer:
[tex]y=6x-10[/tex]
Step-by-step explanation:
First, we can find the slope using the two given points.
[tex]m=\frac{y2-y1}{x2-x1}=\frac{-22-8}{-2-3}=\frac{-30}{-5}=6[/tex]
Then, we can use the slope we just found and one of the given points to find the y-intercept.
[tex]y=mx+b\\y=6x+b\\8=6(3)+b\\8=18+b\\b=-10[/tex]
And we can put our equation together.
[tex]y=6x-10[/tex]

Which representation does NOT show Y as a function of X?
Answer:
D
Step-by-step explanation:
A function is valid if each x input has a different y counterpart
In picture D both 3 and 5 repeat --> (3,2)(2,6) and (5,6)(5,8)
This would create an undefined line that would fail the vertical line test (multiple x values on one y value)

Answer:
y=4x+4
Step-by-step explanation:
substiute the 1 for the y and the 8 for the x in the form (8=4*1+b)
subtract for so it cancels out on the right and leaves you with 4 on the left equals b on the right.

Given Equation x² -4x + 1 = k(x - 4) with equal rootsTo findThe value of kSolutionThe equation in standard form is:
x² -4x + 1 = k(x - 4)x² - 4x - kx + 1 + 4 = 0x² - (k + 4)x + 5 = 0When the quadratic equation has equal roots its discriminant is zero

An arithmetic sequence is represented by the recursive formula A(n) = A(n-1) + 8. If the first term in the sequence is 4, write the explicit formula
Answer:
A(n) = 4 + 8(n-1)
Step-by-step explanation:
A(n) = A(n-1) + 8
A(1) = 4
So A(2) = A(1) + 8 = 4 + 8
A(3) = A(2) + 8 = A(1) + 8 + 8 = 4 + 8 + 8
A(n) = 4 + 8(n-1)
The explicit formula for the arithmetic sequence with the given recursive formula A(n) = A(n-1) + 8 and the first term A(1) = 4 is A(n) = 8n - 4.
Given that the first term (A(1)) is 4, we can observe that each subsequent term is obtained by adding 8 to the previous term.
The general formula for an arithmetic sequence is A(n) = A(1) + (n-1)d, where A(n) represents the nth term, A(1) is the first term, n is the term number, and d is the common difference.
The first term (A(1)) is 4, and the common difference (d) is 8.
Plugging these values into the general formula, we have:
A(n) = 4 + (n-1)×8
A(n) = 4 + 8n - 8
A(n) = 8n - 4

Answer:
C. x = 57, y = 25Step-by-step explanation:
∠LKU = 1/2∠EKU ⇒ ∠LKU = 1/2(90°) = 45°
(x - 12)° = 45°x = 57°∠KCE = 90° as diagonals of a square are perpendicular

What is the vertex for the equation f (x) = 6(x – 10)2 – 4?
Answer:
(10, -4)Step-by-step explanation:
The vertex form of the equation of quadratic function with vertex (h, k) is:
f(x) = a(x - h)² + q
f(x) = 6(x - 10)² - 4 - given function
so:
a = 6, h = 10, q = -4

Molly read 50 out of the 200 pages in her fiction book. Joel is also reading a fiction book, but his book has 280 pages in total. If Joel reads x pages such as the ratio of pages he read is a equivalent to the ratio of pages molly has read, find the value of x.
Answer:
[tex]x = 70[/tex]
Step-by-step explanation:
Given
Molly: 50 out of 200
Joel: x out of 280
Required
Find x
Start by representing the giving parameters as ration
Molly= 50 : 200
Joel = x : 280
From the question, the ratios are equivalent. So,
[tex]50 : 200 = x : 280[/tex]
Convert to fractions
[tex]\frac{50}{200} = \frac{x}{280}[/tex]
Solve for x
[tex]x = \frac{50}{200} * 280[/tex]
[tex]x = \frac{1}{4} * 280[/tex]
[tex]x = \frac{280}{4}[/tex]
[tex]x = 70[/tex]
two customers went to a dry cleaners to get clean their shirts and pants. Each shirt cleaning costs the same amount, and each pants cleaning costs the same amount. The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning. The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning. What was the cost, in dollars, of each shirt cleaning?
Answer:
$3.00
Step-by-step explanation:
5x + 3y = 30 - - - - - 1 x 4
3x + 4y =29 - - - - - -2 x 3
--------------------------------------------
20x +12y = 120 - - - - 3
9x + 12y = 87 - - - - - 4
--------------------------------------------
3-4
20x - 9x= 120 - 87
11x = 33
X= 33
11
X = 3
The cost of cleaning each shirt is 3 dollars.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Assuming the cost of cleaning 1 shirt is x and the cost of cleaning 1 pant is y.
The first customer paid $30.00 for 5 shirt cleanings and 3 pants cleaning.
∴ 5x + 3y = 30...(i)
The second customer paid $29.00 for 3 shirt cleanings and 4 pants cleaning.
∴ 3x + 4y = 29...(ii)
Now to cancel out 'x' in both equations we multiply eqn(i) by 3 and eqn(ii) by 5.
So, 15x + 9y = 90...(iii) and 15x + 20y = 145...(iv)
Now subtracting (iii) from (iv) we get 11y = 55 ⇒ y = 5 and substituting the value of y in eqn(iv) we get x = 3.
The cost of cleaning each shirt is 3 dollars.

Answer: [tex]y=\frac{1}{2} x+2[/tex]
Step-by-step explanation:
The format for these equations are y=mx+b. Find the slope, which is the change in y over the change in x. When you apply this formula, you get 1/2. To find the y-intercept, just count from the origin to the place the line meets the y-axis, which is 2. Putting it together, you get the equation [tex]y= \frac{1}{2}x+2[/tex]
