Answer:
x =4, x = -6
Step-by-step explanation:
1. Square root the whole equation on both sides
2. You get x+1 = ±5 as the answer.
3. Simplify that to get x = 4 and x = -6.
4. This equation is a quadratic equation, so you should get 2 answers.
Answer:
x=6,−4
Step-by-step explanation:
1.Take the square root of each side of the equation to set up the solution for x
2.Remove the perfect root factor x−1 under the radical to solve for x.
3. Simplify the right side of the equation.
4. The complete solution is the result of both the positive and negative portions of the solution.
5. You get your answer!
x=6,−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.

A

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.
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
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.

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

Step-by-step explanation:
brainliest pls
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)

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 - 15What is the value of x in the figure? (2x+15)°
Answer:
(2x + 15)° = 180°
2x = 180 - 15
2x = 165
x = 165/2
x = 82.5
