Answer:
x=1.5
or
x=1 1/2
Step-by-step explanation:
4x-7>-1
add 7 to both sides
4x=6
divide by 4 on both sides
x=1.5
or
x=1 1/2
The current depth of the hole is at least 20 feet below ground level.
Inequality is an expression that shows the non equal comparison of numbers and variables.
Let d represent the current depth of the hole.
To be at least 40 feet below ground level, he need more than 2 times its current depth.
2d < -40
d < -20
Hence the current depth of the hole is at least 20 feet below ground level.

Answer:
the number doesnt represent an integer?
A. 3
B. 20.1
C. -10
D. 20/4
Step-by-step explanation:
We call integers the “counting numbers, their negatives and zero”. I.e. 0,1,−1,2,−2,3,−3,.. etc.
non-integers means “everything except integers”. Which is not well-defined (i.e. nonsense). Why? Because nobody said what “everything” is.
Therefore, when somebody says “non-integer” he has to specify how he defines “everything”. In this case, our “everything” is probably “real numbers”.
Real numbers have an interesting definition concerning an abstract mathematical object called “field” . Let’s forget about that and let’s focus on a high school definition: Real numbers are probably all the numbers you know. They are those represented by a decimal and their negatives e.g. 345.232… and −243.13242240… where there are “infinitely many” digits at the end. Note that 2.5 is also a real number. Integers are too. Basically, real numbers are the numbers used to measure distances and their negatives.
To summirize, your answer is the following:
“non integers” means everything except the integers, where everything is defined however we want. The most common definition of everything in this case is “real numbers” and therefore the most common interpretation of “non integers” is “reals which are not integers”.
Examples of “reals which are not integers”: 1.5,2.88,1.3333… etc
the answer is
B. 20.1
Y= 4 - 4/5x all you have to do is make it go up 4 from 0 and either go down 4 and go right 5 or up 4 and to the left 5... hope this helped!
Answer:
Step-by-step explanation:
first, we need to find the slope
slope = (y2 - y1) / (x2 - x1)
(-2,1)...x1 = -2 and y1 = 1
(0,8)...x2 = 0 and y2 = 8
now sub
slope = (8 - 1) / (0- (-2) = 7/(0 + 2) = 7/2
point slope form : y - y1 = m(x - x1)
using point (-2,1)....x1 = -2 and y1 = 1
slope(m) = 7/2
now sub
y - 1 = 7/2(x - (-2) =
y - 1 = 7/2(x + 2) <==== here is one answer
y - y1 = m(x - x1)
using point (0,8)...x1 = 0 and y1 = 8
slope(m) = 7/2
now sub
y - 8 = 7/2(x - 0) <===== another possible answer
