what is the solution to -(6m+8) =4(17 - m)
Answer:
m=-38
Step-by-step explanation:
-(6m+8)=4(17-m)
We move all terms to the left:
-(6m+8)-(4(17-m))=0
We add all the numbers together, and all the variables
-(6m+8)-(4(-1m+17))=0
We get rid of parentheses
-6m-(4(-1m+17))-8=0
We calculate terms in parentheses: -(4(-1m+17)), so:
4(-1m+17)
We multiply parentheses
-4m+68
Back to the equation:
-(-4m+68)
We get rid of parentheses
-6m+4m-68-8=0
We add all the numbers together, and all the variables
-2m-76=0
We move all terms containing m to the left, all other terms to the right
-2m=76
m=76/-2
m=-38
The solution to the given equation is [tex]-38[/tex]
We are given -(6m+8) =4(17 - m) Open the bracket in both side by multiplying (-) to the terms at left hand and 4 to the terms at right hand[tex]-6m - 8 = 68 - 4m[/tex]
Select like terms[tex]-6m + 4m = 68+8[/tex]
Simplifying,[tex]-2m = 76[/tex]
[tex]m= \frac{-76}{2}[/tex]
[tex]= -38[/tex]

what information is needed to prove the triangles are congruent using the Hypotenuse-Leg theorem
5. and 6.
The required triangle KLM and triangle QPR has been proved congruent with Hypotenuse-Leg theorem.
What are Pythagorean triplets?In a right angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.
From triangle KLM and QPR,
KM = QR
LK = PQ
Square and subtract above equations,
KM² - LK² = QR² - PQ² - - - - - (1)
From Pythagoras theorem,
hypotenuse ² = perpendicular² + base square,
For triangle KLM
KM² = LK² + LM²
KM² - LK² = LM² - - - - -(2)
For triangle QPR,
QR² = PQ² + PR²
QR² - PQ² = PR² - -- - - - (3)
From equation 2 and 3 put value in equation 1
LM² = PR²
LM = PR
Thus, triangle KLM and triangle QPR proved to be congruent. And the theorem is Hypotenuse-Leg theorem.

Answer:
[tex]1)\ x = 5[/tex]
[tex]2)\ x = 14[/tex]
[tex]3) \ x = 15,\ y = 2[/tex]
Step-by-step explanation:
1) Given that M<1 = 95 + 7x and M<2 = 55 - x, you should look on the diagram to see what type of angles M<1 and M<2 are.
On the diagram at the top, angles 1 and 2 appear to be supplementary angles, meaning they add up to 180 degrees. You can apply this information to creating an equation:
M<1 + M<2 = 180°[tex](95 + 7x) + (55 - x) = 180[/tex]Now you can solve this equation by combining like terms on the left-hand side of the equation.
[tex]150+6x=180[/tex]Subtract 150 from both sides of the equation in order to isolate the variable x.
[tex]6x=30[/tex]Divide both sides of the equation by 6 in order to isolate the variable x completely.
[tex]x=5[/tex]2) You are given that M<3 = 5x + 12 and M<4 = 7x - 16, so look on the diagram at the top to find out what type of angles they are.
Angles 3 and 4 appear to be alternate exterior angles, meaning that they are equal to each other as stated by the Alternate Exterior Angles Theorem. You can use this information to make an equation where M<3 = M<4.
M<3 = M<4[tex]5x+12=7x-16[/tex]Subtract 5x from both sides of the equation, and add 16 to both sides of the equation.
[tex]28=2x[/tex]Divide both sides of the equation by 2 to isolate the variable x completely.
[tex]14=x \rightarrow x=14[/tex]3) Given that M<1 = 7y + 16, M<2 = 2x, and M<3 = 4x - 30, look on the diagram at the bottom to find out what type of angles they are.
Since angles 2 and 3 include an "x" variable, you should start with them first in order to be able to solve for x. Angles 2 and 3 are complementary angles, meaning that they are equal to each other based on the Complementary Angles Theorem. Translate this information into an equation:
M<2 = M<3[tex]2x=4x-30[/tex]Subtract 2x from both sides of the equation and add 30 to both sides of the equation.
[tex]30=2x[/tex]Divide both sides of the equation by 2 in order to isolate the variable x completely.
[tex]15=x \rightarrow x=15[/tex]Now to solve for y - based on the diagram, you can see that angle 1 and angle 2 are vertical angles, meaning that they are equal to each other based on the Vertical Angles Theorem.
You can make them equal to each other in an equation:
M<1 = M<2[tex]7y+16=2x[/tex]We solved for x and know that it is 15, so substitute 15 into the equation for x.
[tex]7y+16=2(15)[/tex][tex]7y+16=30[/tex]Subtract 16 from both sides of the equation.
[tex]7y=14[/tex]Divide both sides of the equation by 7 to isolate the variable x.
[tex]y=2[/tex]Hope this helped! Comment below if you have any clarifying questions.

Which of the following is the best estimate
of the square root of 90 ?
a. 9.1
b. 9.4
C. 9.7
To get the best estimate of the square root of 90 we will apply a short cut.
Square root of 90 will be in the form of a mixed fraction as [tex]a\frac{b}{c}[/tex] or in decimals.
Here, a = square root of a perfect square number nearest to 90.
b = Difference of 90 and the perfect square number
c = Double of 'a'
Nearest square number to 90 = 81
Square root of 81 = 9
So, a = 9
Difference in 90 and 81 = 9
So, b = 90 - 81 = 9
And double of 9 = 18
Therefore, c = 18
Hence, [tex]\sqrt{90}\approx9\frac{9}{18}[/tex]
[tex]\approx9.5[/tex]
So the nearest number given in the option may be 9.4
Therefore, Option B will be the answer.

Given f(x) = x + 9 and g(x) = x2 find (gºf)(x).
Answer:
g(f(x)) = (x + 9)^2 or x^2 + 18x + 81
Step-by-step explanation:
(gºf)(x) is the "c .... " of two functions f(x) and g(x): f(x) is the input to g(x).
We start with g(x): g(x) = x^2. We replace the first x with f(x) and the second x with x + 9:
g(f(x)) = (x + 9)^2 or x^2 + 18x + 81
Robert bought a $5 lottery ticket such that 1 in 100 would win $10, 1 in 1000 would win $100, and 1 in 50 million would win 1 million. What is the expected value of a lottery ticket in dollars?
Does Robert expect to earn a profit if he buys 100 tickets?
By how much?
Answer:
Loss of $4.78
Loss of $478
Step-by-step explanation:
Expected value = Sum of (winning amount x winning probability) - cost of lottery ticket
Expected value = ( $10 x 1/100 + $100 x 1/1000 + $1 million x 1/$50 million ) - $5
Expected value= $0.22 - $5
Expected value= - $4.78
The Negative value of expected value indicates loss)
Amount expected to lose if 100 tickets are bought = 100 x $4.78 = $478

Why did the people of the Neolithic era domesticate both plants and animals? They needed more reliable sources of food and supplies.They wanted more supplies to use to conquer other settlements. They had to find new ways to get more water for their people. They competed to become more advanced than other groups of people.
The correct option is " They needed more reliable sources of food and supplies".
Neolithic is termed the stone period. This is so because this was the evolution of the prehistoric humans that developed and discovered many of the things that are made up of stones.
The people of this era domesticated both flora and fauna that means plants and animals as the forest was their inhabitants, plants were their food eatables and animals were the ones that they can hunt, play, tame, and sometimes can also have them in their meals. They were using plants and animals with various methods and types.
Therefore, the option " They needed more reliable sources of food and supplies" is the correct answer.

Answer:
y = 52
x = 30
Step-by-step explanation:
Hi!
Y is a vertical angle. See <DOB? That's it's vertical pair. So, y = 2x - 8 [vertical angles are congruent].
Now, to find y, we need x. We can find x by using the fact that AB is a straight line. The angles on a straight line add up to 90.
Given the fact that <AOB is 90 degrees, <EOB also has to be 90 degrees.
So, EOB = 90 degrees. Remember that an angle is equal to the sum of the measures of the angles that it is made of.
EOB is therefore equal to <EOD + <DOB.
90 = <EOD + DOB
90 = (x +8) + (2x-8)
90 = 3x
x = 30
Check:
38 + 52 = 90.
So, x = 30
Now, we go back to find y.
y = 2x-8
y = 52
