Find a function rule for the line that passes through the origin (0,0) and the point (5, - 13)
what is the function rule for the line?
a. y= -13/5x
b. y= -5/13x
c. y= 5x -13
d. y= -13x +5
Answer:
The Function rule for line is: [tex]\mathbf{y=-\frac{13}{5}x}[/tex]
Option A is correct option.
Step-by-step explanation:
Find a function rule for the line that passes through the origin (0,0) and the point (5, - 13)
The function rule is of form: [tex]\mathbf{y=mx+b}[/tex]
where m is slope and b is y-intercept
Finding slope:
The formula used to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=0, y_1=0, x_2=5, y_2=-13[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-13-0}{5-0}\\Slope=\frac{-13}{5}\\Slope=-\frac{13}{5}[/tex]
Finding y-intercept
We will use point(0,0) to find y-intercept
[tex]y=mx+b\\0=-\frac{13}{5}(0)+b\\0=0+b\\b=0[/tex]
So, y-intercept is 0
The Function rule for line having slope m=-13/5 and y-intercept b=0:
[tex]y=mx+b\\y=-\frac{13}{5}x+0\\y=-\frac{13}{5}x[/tex]
So, The Function rule for line is: [tex]\mathbf{y=-\frac{13}{5}x}[/tex]
Option A is correct option.

There are a lot of questions here. I'll do problems 7 and 8 to get you started.
====================================================
Problem 7
The given equations are
y = x^2 + 5x - 2
y = 3x - 2
Since both right hand sides are equal to y, we can equate them, get everything to one side, and solve
x^2 + 5x - 2 = 3x - 2
x^2 + 5x - 2 - 3x + 2 = 0
x^2 + 2x = 0
x(x + 2) = 0
x = 0 or x + 2 = 0 ........ zero product property
x = 0 or x = -2
Now plug each x value back into one of the original equations given
If x = 0, then
y = 3x-2
y = 3*0-2
y = -2
Making (0,-2) as one solution. Repeat for the x value x = -2
y = 3x-2
y = 3(-2)-2
y = -8
The point (-2, -8) is the other solution to the system.
-------------------------------
Answer: There are two solutions and they are (0, -2) and (-2, -8)
====================================================
Problem 8
y = -x^2 - 3x + 2
y = x + 6
We'll use the same idea as before
y = -x^2 - 3x + 2
x + 6 = -x^2 - 3x + 2
x + 6 + x^2 + 3x - 2 = 0
x^2 + 4x + 4 = 0
Now factor the left side to solve for x
(x+2)(x+2) = 0
(x+2)^2 = 0
x+2 = 0
x = -2
Use this x value to find y
y = x+6
y = -2+6
y = 4
Or we can cay
y = -x^2 - 3x + 2
y = -(-2)^2 - 3(-2) + 2
y = 4
We get the same y value either way.
-------------------------------
Answer: There is one solution and it is (-2, 4)

help me pls geometry
Answer:
[tex] y = \frac{1}{2}x + \frac{1}{4} [/tex]
Step-by-step explanation:
Equation in slope-intercept form is given as [tex] y = mx + b [/tex]
An equation parallel to [tex] y = \frac{1}{2}x + \frac{5}{2} [/tex] would have the same slope as the equation.
The slope (m) of the line would be ½.
m = ½.
Given that this same line runs through or contains (³/2, 1), we cam find the value of b (y-intercept) by substituting m = ½, x = ³/2, and y = 1 in [tex] y = mx + b [/tex].
Thus:
[tex] 1 = (\frac{1}{2})(\frac{3}{2}) + b [/tex]
[tex] 1 = \frac{3}{4} + b [/tex]
Subtract both sides by ¾
[tex] 1 - \frac{3}{4} = b [/tex]
[tex] \frac{1}{4} = b [/tex]
To derive the equation, substitute m = ½, and b = ¼ in [tex] y = mx + b [/tex].
✔️The equation is:
[tex] y = \frac{1}{2}x + \frac{1}{4} [/tex]
A 17 year old female high school student feels that she is overweight. Her weight is 145 and height 5'4. Calculate the BMI. Round your answer to one decimal place.
Answer:
BMI is 24.9
Step-by-step explanation:
In order to calculate the student's BMI we first need to convert her weight into kilograms and her height into meters. We know that there are 39.37 inches in a meter and every foot has 12 inches. Therefore, since the student is 5ft 4 inches, this means she is 64inches tall. Now we can divide this by 39.37 to find her height in meters
64 / 39.37 = 1.6256 meters
Now we need to calculate her weight in kilograms. Since there are 2.20462 pounds in 1 kilogram, we simply divide her weight by 2.20462.
145 / 2.20462 = 65.7709 kilograms
Now we use the BMI formula to solve for the students BMI
BMI = [tex]\frac{mass}{height^{2} }[/tex]
BMI = [tex]\frac{65.7709}{1.6256^{2} }[/tex]
BMI = [tex]\frac{65.7709}{2.6425}[/tex]
BMI = 24.88
Therefore we can see that the students BMI is 24.9

Part b
What is the y-intercept of the function
Answer:
A. [tex]f(n) =0.2n+4.8[/tex]
B. The y intercept is 4.8
Step-by-step explanation:
Given
[tex]a_n= 5 + 0.2(n-1)[/tex]
Solving (a): Write as a function.
To do this, we simply substitute f(n) for [tex]a_n[/tex]
[tex]a_n= 5 + 0.2(n-1)[/tex] becomes
[tex]f(n)= 5 + 0.2(n-1)[/tex]
Open Bracket
[tex]f(n) = 5 + 0.2n-0.2[/tex]
Collect Like Terms
[tex]f(n) =0.2n-0.2 + 5[/tex]
[tex]f(n) =0.2n+4.8[/tex]
B. The y intercept.
To get the y intercept, we set n to 0
i.e
[tex]f(0) =0.2 * 0+4.8[/tex]
[tex]f(0) =0+4.8[/tex]
[tex]f(0) =4.8[/tex]
Hence, the y intercept is 4.8

= 2 × ✓2 × x × ✓y
= 2x✓2y
Therefore, ✓8x²y = 2x✓2y
c. ✓4x²y = ✓4 × ✓x² × ✓y
= 2 × x × ✓y
= 2x✓y
Therefore, ✓4x²y = 2x✓y
d. ✓16xy² = ✓16 × ✓x × ✓y²
= 4 × ✓x × y
= 4y✓x
Therefore, ✓16xy² = 4y✓x
e. ✓8xy² = ✓8 × ✓x × ✓y²
= ✓4 × ✓2 × ✓x × ✓y²
= 2 × ✓2 × ✓x × y
= 2y✓2x
Therefore, ✓8xy² = 2y✓2x

What are the coordinates of the point on the directed line segment from
(-6, -10) to (9, 2) that partitions the segment into a ratio of 1 to 2?
Answer:
The coordinates of point that divides the given line in ratio 1:2 are (-1,-6)
Step-by-step explanation:
Given that:
(x1,y1) = (-6,-10)
(x2,y2) = (9,2)
If a point (x,y) divides a line into ratio m:n, the coordinates can be found out by the formula
[tex](x,y) = (\frac{nx_1+mx_2}{m+n} , \frac{ny_1+my_2}{m+n})[/tex]
As given ratio is: 1:2
so m= 1
n = 2
Putting the values in the formula we get
[tex]= (\frac{(2)(-6)+(1)(9)}{1+2} , \frac{(2)(-10)+(1)(2)}{1+2})\\=(\frac{-12+9}{3} , \frac{-20+2}{3})\\=(\frac{-3}{3} , \frac{-18}{3})\\=(-1,-6)[/tex]
Hence,
The coordinates of point that divides the given line in ratio 1:2 are (-1,-6)

Si la probabilidad es 0.70 de que un estudiante con muy altas calificaciones entre al TEC ¿Cual es la probabilidad de que tres de cinco estudiantes con muy altas calificaciones entren al TEC?
Answer:
La probabilidad de que el estudiante entre, es 0.7
Entonces la probabilidad de que el estudiante no entre, es 1 - 0.7 = 0.3.
Ahora, si de 5 estudiantes, 3 entran y 2 no, entonces la probabilidad para un dado arreglo es: 0.7 tres veces, y 0.3 dos veces.
Y la probabilidad conjunta es igual al producto de las probabilidades individuales.
P = (0.7^3)(0.3^2)
Pero esto es para un arreglo, tenemos que tener en cuenta las permutaciones.
Sabemos que para M elementos, el numero de diferentes arreglos de N elementos (tal que N ≤ M) es:
[tex]C(M, N) = \frac{M!}{(M - N)!*N!}[/tex]
En este caso, tenemos que M = 5 y N = 3, entonces tenemos:
[tex]C(5, 3) = \frac{5!}{2!*3!} = 5*4/2 = 10[/tex]
Entonces la probabilidad va a ser:
P = 10* (0.7^3)(0.3^2) = 0.3087
