Find the equation of a line with the given information:
f(- 6) = 8 and f( - 8) = – 1.
Wrote answer in point slope form
Answer:
[tex]y -8= \frac{9}{2}(x +6)[/tex]
Step-by-step explanation:
Given
[tex]f(-6) = 8[/tex]
[tex]f(-8) = -2[/tex]
Required
Determine the equation in point-slope form
The general function notation is:
[tex]f(x) = y[/tex]
So, in [tex]f(-6) = 8[/tex]
[tex](x_1,y_1) = (-6,8)[/tex]
[tex]f(-8) = -1[/tex]
[tex](x_2,y_2) = (-8,-1)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2-x_1}[/tex]
[tex]m = \frac{-1-8}{-8-(-6)}[/tex]
[tex]m = \frac{-1-8}{-8+6}[/tex]
[tex]m = \frac{-9}{-2}[/tex]
[tex]m = \frac{9}{2}[/tex]
The equation is then calculated as:
[tex]y -y_1= m(x-x_1)[/tex]
[tex]y -8= \frac{9}{2}(x - (-6))[/tex]
[tex]y -8= \frac{9}{2}(x +6)[/tex]
On which triangle can the law of cosines be applied once to find an unknown angle measure? Law of cosines: a2 = b2 + c2 – 2bccos(A) Triangle X W Y is shown. Angle X Y W is a right angle. The length of hypotenuse W X is y, the length of X Y is a, and the length of W Y is 9. Triangle W X Y is shown. Sides W X and X Y are congruent. The length of W Y is 7. Triangle W X Y is shown. Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y. Triangle W X Y is shown. The length of W X is 10, the length of X Y is 8, and the length of W Y is 16.
Answer:
C) Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y.
Step-by-step explanation:
On which triangle can the law of cosines be applied once to find an unknown angle measure?
The Law of cosines is given as:
a² = b² + c² - 2bccos(A)
From the options given above, the correct option is Option C
C) Angle X Y W is 76 degrees. The length of X Y is 5, the length of W Y is 10, and the length of W X is y.
This is because:
Law of Cosines helps us to find an unknown side of a triangle when we are given 2 known sides and 1 angle.
In the above question, we are given angle 76 degree, and the length of two sides: The length of X Y is 5, the length of W Y is 10
The unknown side is the length of W X which is represented as y.
Hence, Option C is the correct option.

HELPPPPOMOGMGOGMGOGKM PLS ANSWER THIS CORRECTLY PLZZZ THIS IS FOR A VERY IMPORTANT TEST YOUWILL GET BRAINLIEST HELP
Answer:
i cant give u the answer but here is an example hope this helps slope = "rise over run" the difference in y values divided by the difference in x values
= 6/-3 = -2 = m. It's negative because as x increases, y decreases
plug that into the point slope formula, with either point. generally use the most simple point
y-h= m(x-k) where m= -2 and (k,h) = (2,-2)
y+2 = -2(x-2)
simply if you want
Y = -2x +4 -2 = -2x +2
or
2x +y = 2
Step-by-step explanation:
Answer:
Your slope is -1
Your y inter is -3

use long or synthetic division to find the following quotients
(x^3+2x^2!22x-45)÷(x+5)
Answer:
[tex]\boxed{\textsf{ The quotient is $\sf x^2-3x-7$ and the remainder is (-10).}}[/tex]
Step-by-step explanation:
Here we will be using long division method to find the quotient . Here we need to divide (x³+2x²-22x-45) and (x+5) . So lets divide .
x+5) x³+2x²-22x-45 ( x² -3x -7
x³ + 5x²
- -
______________
- 3x²-22x -45
-3x² -15x
+ +
______________
-7x -45
-7x -35
______________
-10
Quotient = x² -3x -7
Remainder = (-10)
★Hence the quotient is x² -3x -7 and the remainder is (-10) .6X + 8Y - 4Z = 5
1X + 2Y + 5Z = 9
9X - 3Y + 3Z = 6
Por favor cómo se resuelve esta matriz por método Gauss-Jordan
Responder:
la solución (x, y, z) es (4.48, 4.86, -1.04)
Explicación paso a paso:
Dadas las ecuaciones simultáneas;
6X + 8Y - 4Z = 5 .... 1
1X + 2Y + 5Z = 9 ... 2
9X - 3Y + 3Z = 6 .... 3
Primero necesitamos reducir el sistema de ecuaciones
Ecuación 1 * 1
Ecuación 2 * 4
__________
6X + 8Y - 4Z = 5
4X + 8Y + 20Z = 36
Restar
6x-4x - 4z-20z = 5-36
2x-24z = 31 ... 4
también
ecuación 2 * 3
ecuación 3 * 2
_______________
1X + 2Y + 5Z = 9 * 3
9X - 3Y + 3Z = 6 * 2
_______________
3x + 6y + 15z = 27
18x - 6 años + 6z = 12
Agregar
3x + 18x + 15z + 6z = 27 + 12
21x + 21z = 39 ...... 5
Resolviendo 4 y 5
2x-24z = 31 ... 4 * 21
21x + 21z = 39 ...... 5 * 2
____________
42x - 504z = 651
42x + 42z = 78
Sustraer
-504x - 42z = 651-78
-546z = 573
z = -573/546
z = -1.05
Sustituye z = -1.05 en 4
De 4;
2x-21z = 31
2x - 21 (-1,05) = 31
2x + 22,04 = 31
2x = 31-22.04
2x = 8,96
x = 8,96 / 2
x = 4,48
Obtener y
De 2:
X + 2Y + 5Z = 9
4.48 + 2y + 5 (-1.04) = 9
2 años + 4,48-5,2 = 9
2y = 9 + 0,72
2 años = 9,72
y = 9,72 / 2
y = 4,86
Por tanto, la solución (x, y, z) es (4.48, 4.86, -1.04)

Mr. Tanner bought some boxes of markers with 18 markers in each box. He kept 2 markers and gave the rest to his students. Use the equation below to calculate the number of boxes (b) he bought. 18b – 2 = 214
Answer: 18b-2+2=214 +2
Step-by-step explanation:Add 2 both sides of the equation
Answer:
b = 12; he bought 12 boxes.
Step-by-step explanation:
18b - 2 = 214 (subtract 2 on both sides)
18b = 216 ( divide 18 on both sides to get 'b' alone)
b = 12
