Answer:
x = 0, y = -1
Step-by-step explanation:
10x = 5y + 5
y = 2x - 1
======================
10x = 5(2x - 1) + 5
10x = 10x - 5 + 5
x = 0
======================
y = 2x - 1
y = -1

find ML, JK=3x+11, ML=10x-12, NP=45
Answer:
[tex]ML = 58[/tex]
Step-by-step explanation:
Given
[tex]JK=3x+11, ML=10x-12, NP=45[/tex]
See attachment
Required
Length ML
First, calculate x using the following equivalent ratios
[tex]JK : NP = NP : ML[/tex]
Express as fraction
[tex]\frac{JK }{ NP} = \frac{NP }{ ML}[/tex]
Cross Multiply
[tex]JK * ML = NP * NP[/tex]
Substitute values:
[tex](3x +11) * (10x - 12) = 45 * 45[/tex]
Expand
[tex]30x^2 - 36x + 110x - 132 = 2025[/tex]
[tex]30x^2 +74x - 132 = 2025[/tex]
Collect like terms
[tex]30x^2 +74x - 132 - 2025=0[/tex]
[tex]30x^2 +74x -2157=0[/tex]
Using a calculator:
[tex]x \approx -10[/tex] and [tex]x \approx 7[/tex]
Given that:
[tex]ML=10x-12[/tex]
Substitute values for x
[tex]ML=10*-10-12 = -100 - 12 = -112[/tex]
[tex]ML=10*7-12 = 70 - 12 = 58[/tex]
ML cannot be negative; So:
[tex]ML = 58[/tex]
Help ASAP will make brainliest please
Answer:
A: 5% High risk; 15% medium risk; 80% low risk.
Step-by-step explanation:
Option A will be the most appropriate because it follows the risk pyramid pattern that guides investors.
Now, in the risk pyramid, the low risk investment should be the biggest and should contain a large part of your assets since it will be low in risk and have good foreseeable returns. The medium risk investment should be the next biggest as it allows stable returns while capital appreciates. While the high risk return investment should be the lowest as it should consist of money you can lose and wouldn't really affect you.

Two things that WILL change every time you draw a normal distribution curve for a problem are:
Answer:
The "Bell Curve" is a Normal Distribution. follows it closely, but not perfectly (which is usual). because it looks like a bell. Many things closely follow a Normal Distribution: We say the data is "normally distributed":
Step-by-step explanation:
Answer:
Your most likely answer: Shape + position (if it is talking about the general curve)
Mean + Standard deviation (if it is talking about the parameters)
If it is talking about using a normal distribution to find probability, then the things that change are the side of interest + the test statistic.

Answer:
Perimeter = 25
Step-by-step explanation:
J(-2, 5)
K(1, 1)
L(1, -1)
M(-5, -4)
N(-5, 1)
Formula for distance between 2 coordinates is;
d = √((x_2 - x_1)² + (y_2 - y_1)²)
Thus;
JK = √((1 - (-2))² + (1 - 5)²)
JK = √25
JK = 5
KL = √((1 - 1)² + (-4 - 1)²)
KL = √25
KL = 5
LM = √((-5 - (-1))² + (-4 - (-1))²)
LM = 5
MN = √((-5 - (-5))² + (1 - (-4))²)
MN = 5
JN = √((-5 - (-2))² + (1 - 5))²)
JN = 5
Thus;
Perimeter = 5 + 5 + 5 + 5 + 5
Perimeter = 25

Evaluate this please
Answer:
6561
Step-by-step explanation:
So, lets just go over what we know:
The exponent is 4, meaning the number will be multiplyied by itself 4 times.
The number is -9, so we are going to multiply it by -9, 4 times.
We can think of it like this:
9*9*9*9
I used postive nines instead of negative nine since the sign will be postive.(Because its a even exponent)
Now lets solve:
9*9*9*9
=
81*9*9
=
729*9
=
6561
So this is the answer!
Hope it helps! :)
find the inverse[tex]f(x)=x^{2} +10[/tex]
9514 1404 393
Answer:
[tex]f^{-1}(x)=\pm\sqrt{x-10}[/tex]
Step-by-step explanation:
You can find the inverse of
y = f(x)
by solving for y:
x = f(y)
__
x = y² +10
x -10 = y² . . . . . . . . subtract 10
±√(x -10) = y . . . . . take the square root
The inverse relation is ...
[tex]\boxed{f^{-1}(x)=\pm\sqrt{x-10}}[/tex]
__
It is not a function unless some restriction is placed on the domain of f(x).
find the value of each variable. NEED ANSWER ASAP TYY SO MUCH IN ADVANCE
Step-by-step explanation:
14) sin45 = x/6 ---> x = 6sin45 = 4.24
cos45 = y/6 ---> y = 6cos45 = 4.24
15) Use sine law to solve for x, y and z.
[tex] \frac{x}{sin45} = \frac{25 \sqrt{2} }{sin60} \\ x = 25 \sqrt{2} \frac{sin45}{sin60} = 25 \sqrt{2} \frac{ \frac{ \sqrt{2} }{2} }{ \frac{ \sqrt{3} }{2} } \\ = \frac{50}{3} \sqrt{3} [/tex]
[tex]cos60 = \frac{y}{ \frac{50}{3} \sqrt{3} } \\ y = ( \frac{50}{3} \sqrt{3} )cos60 = ( \frac{50}{3} \sqrt{3} ) (\frac{ \sqrt{3} }{2} ) \\ y = 25 [/tex]
[tex]cos45 = \frac{z}{25 \sqrt{2} } \\ z = (25 \sqrt{2} )cos45 = (25 \sqrt{2} )( \frac{ \sqrt{2} }{2} ) \\ = 25[/tex]
Which expression is not equal to the expression shown?
Answer:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex]
Step-by-step explanation:
When pulged into a calculator:
[tex]3^{3}[/tex] ÷ [tex]3^{-4}[/tex] = 2187
When your options are pulged in you get this:
[tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] = [tex]\frac{1}{2187}[/tex]
[tex]3^{3}[/tex] · [tex]3^{4}[/tex] = 2187
[tex]3^{7}[/tex] ÷ [tex]3^0[/tex] = 2187
3 · [tex]3^6[/tex] = 2187
because [tex]3^{-3}[/tex] ÷ [tex]3^{4}[/tex] doesn't equal 2187 that is your answer.

explain why 2+x and x+3 are equivalent
Check whether the two expressions 2x+3y2x+3y and 2y+3x2y+3x equivalent.
The first expression is the sum of 2x2x 's and 3y3y 's whereas the second one is the sum of 3x3x 's and 2y2y 's.
Let us evaluate the expressions for some values of xx and yy . Take x=0x=0 and y=1y=1 .
2(0)+3(1)=0+3=32(1)+3(0)=2+0=22(0)+3(1)=0+3=32(1)+3(0)=2+0=2
So, there is at least one pair of values of the variables for which the two expressions are not the same.

9514 1404 393
Answer:
3(x^3)y -6x(y^2) +93Step-by-step explanation:
The above-listed answer choices are the only ones that are self-consistent.
The quotient choices all have a leading coefficient of 3, and the result of dividing by <some number> is a leading coefficient of 1. Obviously, the <some number> must be 3 (first choice on the second menu).
Looking only at the constant term, we see that after division by 3, we have 3. So the original quotient constant term must be 3×3 = 9 (first choice on the first menu). Note that we have chosen the correct answer simply by looking at coefficients, not even bothering with actual division of variables.
