Answer:
y = -1/2 x - 1
Step-by-step explanation:
The expression in point-slope form is expressed as;
y-y0 = m(x-x0)
(x0,y0) = (6, -4)
slope m = -1/2
Substitute into the formula
y-(-4) = -1/2(x-6)
y+4 = -1/2(x-6)
2(y+4) = -(x-6)
2y+8 = -x+6
2y = -x+6-8
2y = -x-2
y = -1/2 x -2/2
y = -1/2 x - 1
Hence the answer in slope-intercept form is y = -1/2 x - 1

Rule 1: Multiply by 2, then add 1/3 starting from 1. Rule 2: Add 1/2, then multiply by 4 starting from 0. What is the fourth ordered pair using the two sequences
Answer:
(10 1/3, 42)
Step-by-step explanation:
a1 = 1
a2 = a1×2 + 1/3 = 2 1/3
a3 = a2×2 + 1/3 = (a1×2 + 1/3)×2 + 1/3 = a1×4 + 2/3 + 1/3 =
= 4 + 3/3 = 5
a4 = a3×2 + 1/3 = ... = 10 1/3
b1 = 0
b2 = (b1 + 1/2)×4 = (0 + 1/2)×4 = 1/2 × 4 = 2
b3 = (b2 + 1/2)×4 = ((b1 + 1/2)×4 +1/2)×4 = 16×b1 + 16/2 + 4/2=
= 16/2 + 4/2 = 8 + 2 = 10
or (to check we made no mistake)
= (2 + 1/2)×4 = 8 + 2 = 10. => all ok, no mistake
b4 = (b3 + 1/2)×4 = ... = (10 + 1/2)×4 = 40 + 2 = 42
so, the fourth ordered pair (= the fourth elements of each sequence) is therefore (10 1/3, 42)

There are 30 students in an art class. Fourteen of the students are girls.
What is the ratio of boys to girls?
A.7:8
B.8 :7
C.8:15
D.14:40
E.30:14
Answer: B
Step-by-step explanation: To get the boys part of the ratio you will have to subtract 30 students and 14 students that are girls because all together there are 30 students and since we only know that 14 of them are girls that leaves the rest of the students boys. 30 - 14 = 16 so now we know how many boys there are. 16:14 can be reduced by 2 and that equals to 8:7.
Hope this helps!
The ratio of boys to girls is equal to: B. 8 :7
Given the following data:
Total students = 30 studentsNumber of girls = 14 studentsTo calculate the ratio of boys to girls:
How to calculate ratio.First of all, we would determine the number of boys in the art class by subtracting the number of girl students from the total number of students in this class.
[tex]Total \;students = boys + girls\\\\30=boys + 14\\\\Boys =30-14[/tex]
Boys = 16 students.
For the ratio:
[tex]B:G=16:14[/tex]
Dividing by 2, we have:
[tex]B:G=8:7[/tex]

The size of a TV is the diagonal
measurement of its screen. Will a
46-inch TV fit in a rectangular cabinet
measuring 32 inches long and
28 inches high? Explain.
Answer:
Use the Pythagorean Theorem to calculate the length of the sides of a right triangle. A TV cut in half on the diagonal is a right triangle.
a^2 + b^2 = c^2
a is the width of the TV
b is the height of the TV
c is the diagonal size of the TV
a is equal to the length of b plus 15, and c is equal to 75. If we out those values into the formula, we get this:
(b+15)^2 + (b)^2 = (75)^2
Factoring that out, we get:
(b)^2 + 225 + (b)^2 = 5625
Then..
2b^2 = 5625 - 225
2b^2 = 5400
b^2 = 5400/2
b^2 = 2700
b = ✓2700
b = 51.9615242271 (round it to an even 52)
Next, we know that a = b + 15, so a = 67.
Therefore, the width of the TV is 67 inches, the height is 52 inches, the diagonal is 75 inches, and you have a very strangely shaped television with a 1.288 (approximately 5:4) aspect ratio. Older “square” TVs mostly had a 1.33 (4:3) ratio, and new TVs are usually either 16:9 (1.77) or 21:9 (2.33). While it's not impossible that you have an old square TV with a 75 inch diagonal, it's pretty unlikely…

1. solve equation for y: 3x - 4y = 16
2. what are the x- and y- intercepts of the line: 4x - 3y = -24
3. which ordered pair is on the graph of the equation 6x + 3y = 9
4. what is the slope of the line that passes through the points (4,8) and (1,6)
Answer:
1) y = 3/4x - 4
2) x-intercept: (-6,0) y-intercept: (0,8)
3) (-2,7)
4) slope: 2/3
Step-by-step explanation:
1) subtract 3x from both sides, divide -4 from both sides, simplify right side which gives you y = 3/4x -4
2) to get x-inter: plug in 0 for y and solve for x, the equation should look like 4x = -24, divide both sides by 4 which gives you x = -6
get y-inter: plug in 0 for x and solve for y, the equation should look like -3y=-24, divide both sides by -3 which gives you y = 8
3) plug in the points from the choices and go from there
4) slope formula: m = y2-y1/x2-x1

area of a circle of radius is 6.5?
Answer:
see below
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
A = pi (6.5)^2
A =42.25 pi
If we approximate pi by 3.14
A = 42.25 * 3.14 =132.665
If we use the pi button
A = 132.7322896
Answer:

Es una division el cociente es 14, el divisor 19, calcule el dividiendo si se sabe que el residuo resutó ser el maximo.
Answer:
266
Step-by-step explanation:
En Matemáticas, al realizar la operación de División, la regla es la siguiente:
Dividendo ÷ Divisor = Cociente
En la pregunta anterior, se nos da:
Divisor = 19
Cociente = 14
Dividendo =?
Para encontrar el dividendo,
Dividendo = Divisor × Cociente
Por eso,
Dividendo = 19 × 14
= 266
Por lo tanto, el Dividendo = 266

If you simplify(x^3/x/x)^3, what power rules do you need to simplify it? a. Addition Rule and Power of a Power Rule b. Subtraction rule and Power of a Power. c. Division Rule and Power of a Power Rule d. Power of a Product Rule and Power of a Power Rule e. None of these choices
Answer:
. c. Division Rule and Power of a Power Rule
Step-by-step explanation:
(x^3/x/x)^3
=(x³/x/x)³
First we need to solve the brackets. Anything written in the fraction form a/b/c can be written as a*c/b.
Similarly (x³/x/x)³ can be written as (x*x³/x)³
Solving further the x can be cancelled by x leaving x³ behind.
(x³)³
Now applying the Power of a Power Rule
x³*³= x⁹
First the division rule and then the power rule is applied.

h5. <2 and <7 ( i think this is the same question as the first one)
Step-by-step explanation:
2. 2x + 7 = 123 (you have to make them equal to each other because they are consecutive interior angles)
2x + 7 = 123, subtract 7
2x = 116, divide 2 for both sides to make x by itself
x = 58
3. 78 because of consecutive interior angles

Answer:
minimum value : -1
Step-by-step explanation:
y= 2x^2- |0x+1|
y=2x^2-1
0x has no value they're just putting that in there to trip you up. Also you can view the graph on Desmos graphing calc online to see the minimum value of this function.
x is positive so parabola opens up: meaning minimum value
y-intercept is (0, - 1) so minimum value = -1

Find the horizontal distance x the escalator covers to the nearest tenth of a foot.
Given:
Length of escalator = 26 ft
Angle of depression = 41 degrees
To find:
The horizontal distance x the escalator covers to the nearest tenth of a foot.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
Using this formula for the given triangle, we get
[tex]\cos 41^\circ=\dfrac{x}{26}[/tex]
[tex]26\cos 41^\circ=x[/tex]
[tex]26(0.7547)=x[/tex]
[tex]19.6222=x[/tex]
Round the value to the nearest tenth.
[tex]x\approx 19.6[/tex]
Therefore, the escalator covers 19.6 ft horizontally.
