What slope would make the lines perpendicular? y = 4x + 2 y = -x + 2 Enter the number that belongs in the green box.
Answers
Answer:
The missing number in the green box is 4
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1, which means
if the slope of one of them is m, then the slope of the perpendicular line to it is the negative reciprocal ([tex]\frac{-1}{m}[/tex])The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptLet us solve the question
∵ The equation of the first line is y = 4x + 2
→ Compare it with the form of the linear equation above
∴ m = 4
∵ m is the slope
∴ The slope of the line is 4
∵ The slope of the perpendicular line should be the negative reciprocal of it
∵ The negative reciprocal of 4 is [tex]-\frac{1}{4}[/tex]
∴ The slope of the perpendicular line is [tex]-\frac{1}{4}[/tex]
→ Substitute it in the equation
∴ y = [tex]-\frac{1}{4}[/tex] x + 2
∴ The missing number in the green box is 4

1. Rx-axis
2. Ry-axis
Answer with step-by-step explanation:
1. When you get the reflecting coordinates along x-axis, the signs of the y coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(9, 3), B(6, -4), and C(-1, 5).
2. When you get the reflecting coordinates along y-axis, the signs of the x coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(-9, -3), B(-6, 4), and C(1, -5).

Graphs:The set of ordered pairings (display style [tex](x,y)[/tex]) of a function (display style [tex]f(x)=y[/tex]) in mathematics is known as the graph of that function. These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the typical case where "display style [tex]x[/tex]" and "display style [tex]f(x)[/tex]" are real values.Graph equations:Equations with graphs as the unknowns are known as graph equations in graph theory. The concept of isomorphism is one of the key issues in graph theory. Different graph equations may be used to express the aforementioned graphs.Therefore, the correct equation for the blue graph is [tex]g(x)=(x-4)^{2}[/tex].

film processing costs $4.95, plus $0.35 for each picture printed. Milan paid $11.95 for processing and printing. How many pictures did he have printed?
Answers
Answer:
20 pictures.
Step-by-step explanation:
In this question, we need to find out how many pictures Milan printed.
We know that the film processing costed $4.95 and each picture that was printed costed $0.35.
Lets turn this into an equation with x representing the amount of pictures:
y = 0.35x+ 4.95
Now we need to solve the equation. We can do this by plugging in our known cost, 11.95, into "y".
Solve:
11.95 = 0.35x + 4.95
Subtract 4.95 from both sides.
7 = 0.35x
Divide both sides by 0.35
20 = x
Milan printed 20 pictures.

Question 7 of 25 Which of the binomials below is a factor of this trinomial? x - 6x-16 O A. X-1 O B. X-8 OC. X-16 O D. x-2
Answers
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is [tex]x^{2}-6x-16[/tex].
We need to find the factor of this trinomial.
[tex]x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)[/tex]
The factors of [tex]x^{2}-6x-16[/tex] is (x-2) and (x-8).
So, the factor of [tex]x^{2}-6x-16[/tex] is (x-8). Hence, the correct option is (B).

Answer:
up: (-3, 5); down: (-3, -3); right: (1, -2); left: (-6, -2)
Step-by-step explanation:
As you know, the coordinates of a given point tell you the distance ...
(right, up)
So, a displacement 7 units up adds 7 to the second coordinate value:
A(-3, -2) ⇒ A'(-3, -2+7) = A'(-3, 5) . . . . 7 units up
Likewise, 1 unit down subtracts 1 unit from the second coordinate value:
A(-3, -2) ⇒ A'(-3, -3) . . . . 1 unit down
__
Similarly, left-right changes affect only the first coordinate. Displacements right are added; displacements left are subtracted.
A(-3, -2) ⇒ A'(-3+4, -2) = A'(1, -2) . . . . 4 units right
A(-3, -2) ⇒ A'(-6, -2) . . . . 3 units left
