Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable and x in this equation would be 5 because 5+2=7.
Step-by-step explanation:
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x+2=7, x is a variable and x in this equation is , 5+2=7, but we can work out its value if we try!
Step-by-step explanation:
Write an equation of the line with a slope of -2/7 and a y-intercept of 5.
the formula is y=mx+b
mx is the slope and b is the y-intercept
y=-2/7+5

Complete the equation of the line whose slope is -5/3
and y-intercept is (0, -2).
Answer:
these are tough, it takes a lot of practice to get used to these, sooo
Step-by-step explanation:
we know the slope, m= -5/3, and we're given a point so use the point slope formula
y= mx + b
the point we are given is in this form (x,y)
then plug the information into our point slope formula
y = (-5/3) x + (-2)
y = -5x/3 -2
5x^2-44x+130=-30+16x

I'm trying to understand this!!
Answer:
eric=12
bill=16
Step-by-step explanation:
you can solve this using two simple algebraic equations. this is the key I will be using:
x=bill
y=Eric
x+y=28
x=y+4
since x is by itself in the second equation, I can replace the x in the first equation with y+4
(y+4)+y=28
subtract 4 from both sides
y+y=24
which is also 2y=24
divide both sides by two.
y=12
so now we know Eric is 12 years old.
using this, we can replace the "y" in the second original equation (x=y+4)
x=12+4
x=16
Bill is 16 years old.

Which expression represents the greatest factorization of 32w - 56xy
Answer:
Factor 8 out of 32w - 56xy
8 ( 4w - 7xy )
GCF of 32 and 56 is 8.
So we have 4(8w)-7(8xy)

Marshall compared his 8 most recent cell phone bills. They were $102, $97 $98 $102 $98 $104 $95 and 102 what was the mode cost
Answer:
$102
Step-by-step explanation:
The word MODE is a statistical term that refers to the number in a given set of data that occurs the most.
In the above question, we are given the set of data:
$102, $97, $98, $102, $98, $104, $95 and $102
Rearranging, we have:
$95, $97, $98, $98, $102, $102, $102, $104.
The mode cost in the given data set above is the phone cost bill that occurred the most and this is $102.
$102 occurred 3 times in the data set.

Kip took out a loan for $750. He earned $60 in interest and his interest
rate was 4%. How long did he take to repay the loan?
1 year
2 years
2.5 years
3 years
9514 1404 393
Answer:
(b) 2 years
Step-by-step explanation:
The interest formula is ...
I = Prt . . . . interest rate r on principal P for t years
We can fill in the known values and solve for t.
60 = 750·0.04·t
60/30 = t = 2
The loan was repaid in 2 years.
For what value of k does the equation 6(x + 1) + 2 = 3(k5x + 1) + 3 have no solution?
Answer:
k = (6/15)
Step-by-step explanation:
The equation is:
6*(x + 1) + 2 = 3*(k*5*x + 1) + 3
To have no solutions, we need to have something like:
x + 7 = x + 4
where we can remove x in both sides and end with
7 = 4
So this equation is false, meaning that there is no value of x such that this equation is true, then the equation has no solutions.
First, let's try to simplify our equation:
6*(x + 1) + 2 = 3*(k*5*x + 1) + 3
6*x + 6 + 2 = 3*k*5*x + 3*1 + 3
6*x + 8 = 15*k*x + 6
if 15*k = 6, then the system clerly has no solution.
then:
k = 6/15
then we get:
6*x + 8 = (6/15)*15*x + 6
6*x + 8 = 6*x + 6
8 = 6
The system has no solutions.
