What is the value of x in the equation? 6(x +1) -5x = 8 + 2(x - 1)
can someone explain for me please
Answer:
x = 0
Step-by-step explanation:
6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )
6x + 6 - 5x = 8 + 2x - 2
-x = 0
x = 0
Answer:
I believe it is x= 0 but correct me if I am wrong
Which statement about triangles is true?
A. A triangle can have 2 acute angles.
B. A right triangle can have 2 right angles.
C. An obtuse triangle can have 2 obtuse angles.
D. A triangle can have 1 right angle and 1 obtuse angle.
Answer:
[tex] \fbox{A triangle can have 2 acute angles.}[/tex]
Step-by-step explanation:
Acute angle : The angle whose measure is less than 90° is called actute angle.
Obtuse angle : The angle whose measure is more than 90° is called obtuse angle.
Right angle : The angle whose measure is exact 90° is called right angle.
Property of triangle: The measure of all three angles of a triangle is 180°.
let's solve the actual question now,
Option A - let a triangle have two acute angle x and y respectively and z third angle of the respective triangle,
x + y + z = 180°
(<90°) + (<90°) + z = 180°
z = 180 - (<180)
z <180
the measure of 3rd angle z will be less than 180,
hence a triangle can have 2 acute angles.
Option B - let a right angle triangle have two right angles x and y respectively and z third angle of the respective triangle,
x+y+z = 180
90+90+z = 180
z = 180-180 = 0°
which means the third angle z does not exist and it is not a triangle. Hence a right angle triangle can only have one right angle.
Option C - let a triangle have two obtuse angle x and y respectively and z third angle of the respective triangle,
x + y + z = 180°
(>90°) + (>90°) + z = 180°
z = 180 - (>180)
when one number is subtracted from another number which is greater than that then the result obtain is negative. So the value of third angle z will be negative which is a flaw. Hence third option is also incorrect.
Option D - let a triangle have one right angle and one obtuse angle x and y respectively and z third angle of the respective triangle,
x + y + z = 180°
(90°) + (>90°) + z = 180°
z = 180 - (>180)
Same as option C, the third angle is negative which is a flaw and this option is incorrect too.
Conclusion- A triangle can have 2 acute angles and one right angle. So option A is the correct match.

The model y=1.8x−76.9 represents the relationship between the temperature (°F) and the number of ice cream cones sold. Using the linear regression model, approximate the number of ice cream cones sold when it is 85°F. Round your answer to the nearest whole number.
When it is 85°F, they will sell approximately _ ice cream cones.
Graph of linear equation will be always straight line.
Number of ice cream cones sold be 76.
The relationship between the temperature (°F) and the number of ice cream cones sold is given by model,
[tex]y=1.8x-76.9[/tex]
Where x represent temperature and y represent number of ice cream cone sold.
When temperature is 85°F , it means that , x = 85°F
So, [tex]y=1.8*85-76.9\\\\y= 76.1[/tex]
Thus, number of ice cream cone sold is to be 76.

Answer:
-12y^10
Step-by-step explanation:
First let's rewrite the equation using the commutative property of multiplication
3 x (-4)y^8y^2
Multiply y^8 by y^2 by adding the exponents
y^8+y^2= y^10
3 x (-4)y^10
Now multiply 3 by -4
3 x -4= -12
Finally put them together
-12 + y^10= -12y^10
Answer:
[tex] - 12 {y}^{10} [/tex]
Step-by-step explanation:
We are to simplify:
[tex](3 {y}^{8} )( - 4 {y}^{2} )[/tex]
3 multiplies -4 to get -12, as shown below
[tex]3 \times - 4 = - 12[/tex]
Now, to multiply the exponents which are 8 and 2, we have to use the exponential rule of multiplication: [tex] {a}^{b} \times {a}^{c} = {a}^{b + c} [/tex]
Therefore:
[tex] {y}^{8} \times {y}^{2} = = > {y}^{8 + 2} = {y}^{10} [/tex]
Now, combine -12 and [tex] {y}^{10} [/tex] to get your final answer.
Final answer [tex] = - 12 {y}^{10} [/tex]

David wants to start a lawn care business. He offers his clients two different service options: Plan A charges $20 per month plus $5 an hour. Plan B charges $30 per month plus $3 an hour. He used the system of equations below to determine how much money he can make on both plans. y = 5x + 20 y = 3x + 30 If x represents the number of hours he works, and y represents the total money he makes, how many hours would he have to work to make the same amount of money with both plans?
Answer:
1440 hrs
Step-by-step explanation:
5 is the number of hours he works, and 45 is the total money David makes.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that David offers his clients two different service options.
Plan A charges $20 per month plus $5 an hour.
Plan B charges $30 per month plus $3 an hour.
y = 5x + 20 and y = 3x + 30 are the system of equations to determine how much money he can make on both plans.
y = 5x + 20..(1)
y = 3x + 30..(2)
Substitute equation 2 from equation 1.
y-y=5x+20-3x-30
0=2x-10
2x=10
Divide both sides by 2
x=5.
Now substitute x in equation 1.
y=25+20
y=45
Hence, 5 is the number of hours he works, and 45 is the total money David makes.

Answer:
y-(-8)=4(x-2)
Step-by-step explanation:
This is point-slope form. Point-slope form is y-y₁=m(x-x₁), this is y minus the change in y equals slope (slope is m) times x minus the change in x. An ordered pair is (x, y). You just plug in the missing values. This will get you y-(-8)=4(x-2). I hope this helps! Also, make sure not to put the parenthesis around -8 in the actual box! They are just there to make for less confusion.
