Answer:
False
Step-by-step explanation:
Let us evaluate the problem using the proper order of operation:
4x − 2(5x − 1)
To solve this problem, we use the order of operation called PEMDAS;
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Now, since operations inside the parentheses are of the utmost priority, let us solve this;
4x − 2(5x − 1)
= 4x - 10x +2
= -6x + 2 or 2 - 6x
We see that the solution give is false.

Answer:
Given, x−x1=5
Squaring both the sides,
⇒(x−x1)2=52
⇒x2+x21−2(x)(x1)=25
⇒x2+x21=25+2
⇒x2+x21=27
Now,
x3−x31
=(x−x1)[(x)2+(x1)2+(x)(x1)]
=5(27+1)
=140

Answer:

Step-by-step explanation:
Consider the cube ...
(a +b)³ = a³ +3a²b +3ab² +b³
= a³ +b³ +3ab(a+b)
Now, for a=x and b=1/x, we have ...
(x +1/x)³ = x³ +1/x³ +3(x)(1/x)(x +1/x)
Using the known value for x+1/x, this is ...
7³ = x³ +1/x³ +3(7)
x³ +1/x³ = 7³ -3·7 = 343 -21
x³ +1/x³ = 322

Water is poured into a container at a steady rate. After six minutes, 9.6 gallons of water are in the container. Let g represent the number of gallons of water in the
container after t minutes.
Select the equation that represents the relationship between g and t.
g= 0.6254
gt = 0.625
1.6g =1
g = 1.6t
Answer:
g = 1.6t
Step-by-step explanation:
Here, we want to select the equation that shows the correct relationship between g and t
We are told that after 6 seconds, we have 9.6 gallons of water
So the amount per second will be 9.6/6 = 1.6 gallons per second
So the relationship between the two will be
g = 1.6t
Where t is the time and g is the gallons
Suppose m <6= 147º. Find <1 and m<3
Answer:
∠ 1 = ∠ 3 = 33°
Step-by-step explanation:
∠ 3 and ∠ 6 are same- side interior angles and are supplementary , thus
∠ 3 + ∠ 6 = 180° , that is
∠ 3 + 147° = 180° ( subtract 147° from both sides )
∠ 3 = 33°
∠ 1 and ∠ 3 are vertical angles and congruent, thus
∠ 1 = ∠ 3 = 33°

200$ fee for psychic - 187.5$ earned
200 - 187.5 = 12.5
the club will lose 12.50$

What is the result of solving this equation for x?
y−b=m(x−a)
Answer:
( y-b) / m +a = x
Step-by-step explanation:
y−b=m(x−a)
Divide each side by m
(y−b)m=m/m(x−a)
( y-b)/m = x-a
Add a to each side
( y-b) / m +a = x-a+a
( y-b) / m +a = x
Answer:
y − b = m(x − a)
y − b = mx - ma
(y - b) / m = x - a
((y-b)/m) + a = x

The slope intercept form is y=mx+c, So y= -5/6x + 4 is in slope intercept form.
What is general equation of slope intercept form?The general equation of slope intercept form is y=mx+c
where m is the slope and c is the y intercept
The given equation is y= -5/6x + 4, we have to check whether the given equation in slope intercept form or not.
The given equation is y= -5/6x + 4...(1)
We know that general equation of slope intercept form is y=mx+c...(2)
As we compare equations (1) and (2), we find that equation (1) in the form of (2). so y= -5/6x + 4 is in slope intercept form.
Therefore y= -5/6x + 4 is in slope intercept form.
