Answer:
x = 12
Step-by-step explanation:
For the middle size triangle
short leg = x
long leg = (25 - 9) = 16
ratio = x/16
For the small triangle
short leg = 9
long leg = x
ratio = 9/x
Similar triangles are proportional so
Set the ratios equal
x/16 = 9/x
Cross multiply
x² = 144
Take the square root of both sides
x = 12
Let the vector \mathbf{v}v have an initial point at (-5, -5)(−5,−5) and a terminal point at (-3, 1)(−3,1). Determine the components of vector \mathbf{v}.V.
Answer:
The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.
Step-by-step explanation:
The components of the vector is equal to the vector position of the terminal point relative to the initial point ([tex]\vec v[/tex]), that is:
[tex]\vec v = B(x,y) - A(x,y)[/tex] (1)
Where:
[tex]A(x,y)[/tex] - Initial point.
[tex]B(x,y)[/tex] - Terminal point.
If we know that [tex]A(x,y) = (-5,-5)[/tex] and [tex]B(x,y) = (-3,1)[/tex], then the vector is:
[tex]\vec v = (-3,1) -(-5-5)[/tex]
[tex]\vec v = (2, 6)[/tex]
The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

Gordon, June and Sushil share some sweets in the ratio 4:5:1. Gordon gets 36 more
sweets than Sushil. How many sweets does June get ?
Step-by-step explanation:
Shusil got 8.4 sweets.
Step-by-step explanation:
Gordon share=3/3+5+2×42
3/10×42=12.6
June share=5/3+5+2×42
5/10×42=21
Shusil share=2/3+5+2×42
2/10×42=8.4

If the function m not-equals 0 has an inverse function, which statement must be true? B not-equals 0
Answer:
Option a: m ≠ 0
Step-by-step explanation:
After a small online search, I've found that the complete question is:
If the function f(x) = m*x + b has an inverse function, which statement must be true?
a) m ≠ 0
b) m = 0
c) b ≠ 0
d) b = 0
Ok, if g(x) is an inverse of the function f(x), then:
g( f(x)) = x
f( g(x)) = x
Let's assume that f(x) = m*x + b has an inverse, and this inverse function is g(x).
Because f(x) is linear, g(x) is also linear, then:
g(x) = n*x + c
Let's find the values of A and B.
We know that:
f( g(x)) = x = m*(n*x + c) + b
then
x = m*n*x + m*c + b
Then we must have:
m*n = 1
(m*c + b) = 0
From the first equation m*n = 1
We get:
n = 1/m
The slope of the inverse function is one over the slope of the original function.
Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)
Then the correct option is the option a, m ≠ 0.
Answer:
A

Type the equation of the linear function that passes through the two given points:
(2;9) (4,17)
(3; -17) (-3;13 )
plz help
Answer:
Slope-intercept form of the line:
y = mx + bPoint-slope form of the line:
y - y1 = m(x - x1)------------------------------------
Points:
(2;9) (4,17)The slope:
m = (17 - 9)/(4 - 2) = 4The line:
y - 9 = 4(x - 2)y = 4x - 8 + 9y = 4x + 1----------------------------------
Points:
(3; -17) (-3;13 )The slope:
m = (13 - (-17)) / (-3 - 3) = 4/ -6 = -2/3The line:
y - (-17) = -2/3(x - 3)y = -2/3x + 2 - 17y = -2/3x - 155.) Tiffany is building a model of her bedroom.

What is the solution to the following system of equations
5x + 4y = 40 6x + 4y =44
Answer:
X=4, y=5
Step-by-step explanation:
5x + 4y =40 equation 1
6x + 4y =44 equation 2
-1(5x + 4y)=-1(40) multiply equation 1 by -1 so equation will eliminate y
-5x - 4y=-40 modif equation 1
6x + 4y= 44 equation 2
x=4. Add above 2 equations
solve for y:
5x + 4y =40
5(4)+4y=40
20+4y =40
4y=20
y=5
check solution ;
6x+4y=44
6(4) + 4(5)=44
24 + 20=44
44=44

help me with this math question please I'm giving away brainliests
Answer:
Step-by-step explanation:
Given function in the question is,
[tex]f(x)=\frac{-2x^2-4x}{4x+8}[/tex]
[tex]=\frac{-2x(x+2)}{4(x+2)}[/tex]
[tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]
Given function is not defined at x = -2
At x = -2,
[tex]f(-2)=\frac{1}{2}(2)[/tex]
[tex]=1[/tex]
Therefore, there is a hole in the graph at (-2, 1).
Graph of the function 'f' will be a straight line with a hole at (-2, 1).
Horizontal asymptote → None
Vertical asymptote → None
x-intercept → No x-intercept [Line passes through origin (0,0)]
y-intercept → No y-intercept [Line passes through origin (0,0)]
Hole → (-2, 1)

Solve n - 24 = 28. Be sure to show all work.
Answer:
n= 52
Step-by-step explanation:
n= 28+24
n= 52
Hello
Answer:
n=52
Step-by-step explanation:
n-24=28
n=24+28
n=52
You solve n by adding 24 to both sides to get n by itself which is n= 24+28. After you add 24 and 28 together you get 52. So n=52.
