which of the following inequalities is equivalent to -4x+2<-22-x?
Answer:
[tex]3x>-24[/tex]
Step-by-step explanation:
Given
[tex]-4x+2<-22-x[/tex]
Required
Solve for x
[tex]-4x+2<-22-x[/tex]
We start by taking like terms
[tex]-4x + x < -22 - 2[/tex]
[tex]-3x < -24[/tex]
Divide through by -1: Note, the inequality sign will change:
[tex]3x>-24[/tex]

Jon had $83.50 in his checking account on Monday. On Friday, his balance was
$325.75 after depositing his paycheck. If Jon gets paid $14.25 per hour, how
many hours did he work this week?*
Your answer
Answer:
about 20.5 hours
Step-by-step explanation:
first find out how much money he earned during the week by subtracting the friday balance and the monday balance
375.75 - 83.50 = $292.25 was the amount earned during the week
divide the amount earned by the amount earned per hour
292.25 / 14.25 ≈ 20.5 hours worked that week

In making the decision to return to school for an MBA, prospective students desire to know the time it will take to recoup their investment (forgone wages plus tuition and other direct costs). The time it will take to recoup their investment is normally distributed. You are in charge of estimating this time for a brochure advertising an MBA program at UCLA. You randomly sample 20 past UCLA MBA students and find that the sample average is 3.61 years with a standard deviation of 0.63 years. To estimate the mean number of years required to recoup an investment in a UCLA MBA to within 2 months (0.17 years) with 80% confidence, the sample size should be approximately
Answer:
The value is [tex]n =23[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 20
The sample mean is [tex]\= x = 3..61 \ years[/tex]
The standard deviation is [tex]\sigma = 0.63 \ years[/tex]
The margin of error is [tex]E = 0.17 \ years[/tex]
From the question we are told the confidence level is 80% , hence the level of significance is
[tex]\alpha = (100 - 80 ) \%[/tex]
=> [tex]\alpha = 0.20[/tex]
Generally from the normal distribution table the critical value of is
[tex]Z_{\frac{\alpha }{2} } = 1.282[/tex]
Generally the sample size to estimate the mean number of years required to recoup an investment in a UCLA MBA to within 2 months is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2[/tex]
=> [tex]n = [\frac{1.282 * 0.63}{0.17} ] ^2[/tex]
=> [tex]n =23[/tex]

Is the relation a function?
Answer:
No!
Step-by-step explanation:
The domain (x) cannot have 2 values. In this case, -4 is -3, and -4 is also 8.
This is not a function!
Look at points C and D on the graph:
What is the distance (in units) between points C and D? Round your answer to the nearest hundredth.
5.50 units
6.40 units
9.00 units
41.00 units
Answer:
I think its 6.40 but I'm not sure.
A limousine company charges a flat fee of $35 plus $2 per mile to ride a limousine. Write an equation in slope intercept-form where x, represents each mile and y, represents the total cost of the ride.
**This is due in 20 minutes!! Please HELP.**
Answer:
y=2x+35
Step-by-step explanation:
so y is what it's equal too so you put y=
then since its $2 every mile you put them next to eachother like
2x so y=2x
then there is just a plain fee of $35 so you add that to the equation which is what makes it look like
y=2x+35
Hope this helps!! :D
Determine whether the triangles are congruent by sss sas asa aas hl
Answer: SSS
Step-by-step explanation:
SSS congruence postulate: If all the three sides of one triangle are equivalent to the corresponding three sides of the another triangle, then the two triangles are congruent.
In the given figure, we have
ΔPQR and ΔPQS such that
PQ = PQ [common]
PR= PS [Given]
RQ = QS [Given]
By SSS congruence postulate,
ΔPQR ≅ΔPQS
So, the right choice : "SSS"
the perimeter of a triangle z measures 48 cm . it was dilated with a scale factor of 0.8 to form triangle p . what is the perimeter of triangle
Answer:
The perimeter of the p triangle = 38.4 cm
Step-by-step explanation:
Given
The perimeter of a triangle z be = 48 cm
The triangle is dilated by a scale factor of 0.8
To determine
What is the perimeter of the triangle after it is dilated by a scale factor of 0.8?
As the scale factor < 1, it means the new perimeter will be reduced.The new perimeter of the triangle p can be calculated by multiplying the perimeter of the original triangle z by 0.8
i.e.
Perimeter of triangle p = 48 × 0.8 = 38.4 cm
Therefore, the perimeter of the triangle p is = 38.4 cm

Answer:
N = 76
Step-by-step explanation:
[tex]T = 50 + \frac{N - 40}{4}[/tex]
If T = 59,
[tex]59 = 50 + \frac{N - 40}{4}[/tex]
Simplify:
[tex]9 = \frac{N - 40}{4}[/tex]
[tex]36 = N - 40[/tex]
N = 76

{x{ x + 4<0 or 6x>-12)
Answer:
[tex]x\in (-\infty , -4) \cup (-2,+\infty)[/tex]
Step-by-step explanation:
Solve the system of inequalities:
x + 4 < 0
OR:
6x > -12
The first inequality yields the solution:
x < -4
The second inequality gives the solution:
x > -2
The total solution is the disjunction of the individual solutions, i.e., the union of both.
It can be expressed as
[tex]\mathbf{x\in (-\infty , -4) \cup (-2,+\infty)}[/tex]

Roy kayaked up the river and then back in a total of 6 hours. The trip was 4 miles each way and the current was difficult. If Roy kayaked at a speed of 6 mph, what was the speed of the current? Round your answer to 2 decimal places.
9514 1404 393
Answer:
5.29 mph
Step-by-step explanation:
The time is given by ...
time = distance/speed
Then the total time for the round trip, using x as the speed of the current, is ...
4/(6+x) +4/(6-x) = 6
where distances are in miles, time is in hours, and speed is in miles per hour.
Multiplying by the product of the denominators, we have ...
4(6 -x) +4(6 +x) = 6(6 -x)(6 +x)
48 = 6(36 -x^2)
x^2 = 28
x = √28 ≈ 5.29 . . . . miles per hour
The speed of the current was about 5.29 miles per hour.

Walnuts for Sale. It costs $4.80 to buy 3/4 pound of chopped walnuts. How much would it cost to purchase 8.2 pounds of walnuts?
Answer:
$52.48
Step-by-step explanation:
We can set up a proportion.
$4.80 is to 0.75 lb as x is to 8.2 lb.
4.8/0.75 = x/8.2
0.75x = 4.8 * 8.2
0.75x = 39.36
x = 52.48
Answer: $52.48

consider the following qaudratic function .f(x)=9x^2
Question:
Consider the following quadratic function. f(x) = −9x^2 + 16x − 13.
Identify the vertex
Answer:
[tex](\frac{8}{9},-\frac{53}{9})[/tex]
Step-by-step explanation:
Given
[tex]f(x) = -9x^2 + 16x - 13[/tex]
Required
Identify the vertex
The vertex of an equation is represented as:
[tex](x,f(x)) = (\frac{-b}{2a},f(x))[/tex]
i.e.
[tex]x = -\frac{b}{2a}[/tex]
In [tex]f(x) = -9x^2 + 16x - 13[/tex]
[tex]a= -9[/tex] [tex]b = 16[/tex] [tex]c = -13[/tex]
[tex]x = -\frac{b}{2a}[/tex] becomes
[tex]x = -\frac{16}{2 * -9}[/tex]
[tex]x = \frac{16}{2 * 9}[/tex]
[tex]x = \frac{8}{9}[/tex]
Substitute 8/9 for x in [tex]f(x) = -9x^2 + 16x - 13[/tex]
[tex]f(8/9) = -9(8/9)^2 + 16(8/9) - 13[/tex]
[tex]f(8/9) = -9(64/81)+ (16*8/9) - 13[/tex]
[tex]f(8/9) = -64/9 + (128/9) - 13[/tex]
Take LCM
[tex]f(\frac{8}{9}) = \frac{-64 + 128 -117}{9}[/tex]
[tex]f(\frac{8}{9}) = \frac{-53}{9}[/tex]
[tex]f(\frac{8}{9}) = -\frac{53}{9}[/tex]
Hence, the vertex is:
[tex](\frac{8}{9},-\frac{53}{9})[/tex]
