X < 2
X > -2
X > 2
Step-by-step explanation:
Simplify x in the inequality.
Divide both -2x and 4 by -2:
[tex]\frac{-2x}{-2} < \frac{4}{-2}[/tex]
Answer:
[tex]x > -2[/tex]
The sign has switched since the terms have been divided by a negative number.
Answer:
C. x>-2Step-by-step explanation:
The solution is to isolate the term x from one side of the equation.
-2x<4First, multiply by -1 from both sides.
(-2x)(-1)>(4)(-1)
Solve.
2x>-4
Then, divide by 2 from both sides.
2x/2>-4/2
Solve.
-4/2=-2
x>-2
Therefore, the correct answer is x>-2.

A car has an initial velocity of 10 m/s and final velocity of 43 m/s. The time taken
to reach the final velocity was 3 seconds. What is the acceleration of the car?
Hint: Acceleration (in terms of velocity) = (final velocity - initial velocity)/(time) *
Answer:
160 m/s
Step-by-step explanation:
vi= 10m/s
a= 5om/s*2
t=3 second
vf=?
frist step: find s(distance)
s=vit+1/2 at*2=10m/s x3s +0.5 x50m/s*2 (3s)*2 =30m+225m=255m
second : find vf
s=(vf+vi)/2 xt
vf=2s/t- vi=2(255m)/3s -10 m/s=170 m/s-10m/s=160m/s
Therefore , the final velocity of the car is 160m/s
Walter is making curry for dinner. The recipe says that the curry should cook for 1 hour and 25 minutes. He has been cooking the curry for 59 minutes. According to the recipe, how much longer does Walter need to cook the curry? Write the answer in minutes. minutes
Answer:
26 minutes.
Step-by-step explanation:
1 hour = 60 minutes. 60 minutes + 25 miuntes= 85 minutes of total cook time. 85 - 59 = 26. We do this because he has already cooked for 59 minutes, and the total time is 85 minutes.
Solve (x 9)2 = 25. apply the square root property of equality: isolate the variable. startroot (x 9) squared endroot = plus or minus startroot 25 endroot if x 9 = 5, then x = . if x 9 = –5, then x = .
When a positive sign is considered then the value of x is -4 and when a negative sign is considered then the value of x is -14.
What is simplification?Simplification is to make something easier to do or understand and to make something less complicated.
The equatiuon is (x + 9)² = 25.
Take square root on both sides, then we have
(x + 9) = ±5
For positive signs, we have
x + 9 = 5
x = -4
For negative signs, we have
x + 9 = -5
x = -14

The zeros of a polynomial are 3/2 and 2/5. Find the polynomial.
___x²− ___x+6
Let the zeros of a polynomial be α and β.
Here,
α:- 3/2β:- 2/5Therefore to find the equation of polynomial we have to do sum of zeros of the polynomial and the product of zeros of the polynomial.
Sum of the zeros of polynomial are :-
[tex] \sf \alpha + \beta = \frac{3}{2} + \frac{2}{5} \\ \\ : \rightarrow \: \frac{15 + 4}{10} = \frac{19}{10} [/tex]
Product of the zeros of polynomial are:-
[tex] \sf \: \alpha \beta = \frac{3}{2} \times \frac{2}{5} \\ \\ : \rightarrow \cancel\frac{6}{10} = \frac{3}{5} [/tex]
We know,
p(x) = x² - (α +β)x + αβ
putting values we get
p(x) = x² - 19/10x + 3/5
Hence, This is the required polynomial.
Cars wheel are 28 inches in diameter. How far will the car travel if it’s wheels revolve 10,000 times without slipping?
Answer:
879,200
Step-by-step explanation:
to get the answer we first must get the circumference of the wheel then we must multiply it by 10,000. 28 times 3.14(pie) is equal to 87.92. 87.92 times 10,000 is 879,200.
Note: I rounded pie.

Step-by-step explanation:
not sure what the term is, but AB is equal to BC because AD = DC
using this, you can make the following equation:
5x - 2 = 7x - 8
subtract 5x from both sides
-2 = 7x - 5x - 8
-2 = 2x - 8
add 8 to both sides
-2 + 8 = 2x
6 = 2x
divide both sides by 2

P = All real numbers
Step-by-step explanation:
Step 1: Write equation
4p + 5 + p = 2p + 5 + 3p
Step 2: Solve for p
Combine like terms: 5p + 5 = 5p + 5Subtract 5 on both sides: 5p = 5pDivide both sides by 5: p = pHere we see that any value p would render the equation true. Therefore, we have an infinite amount of solutions.

Answer:
a. -1.60377
b. 0.25451
c. 0.344
d. Option b) 78th
Step-by-step explanation:
The number of pieces in a regular bag of Skittles is approximately normally distributed with a mean of 38.4 and a standard deviation of 2.12.
a)What is the z-score value of a randomly selected bag of Skittles that has 35 Skittles? a) 1.62 b) -1.62 c) 3.40 d) -3.40 e)1.303.
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
z = 35 - 38.4/2.12
= -1.60377
Option b) -1.62 is correct
b) What is the probability that a randomly selected bag of Skittles has at least 37 Skittles? a) .152 b) .247 c) .253 d).747e).7534. .
z = (x-μ)/σ
Mean of 38.4 and a standard deviation of 2.12.
z = (37 - 38.4)/2.12
= -0.66038
P-value from Z-Table:
P(x<37) = 0.25451
The probability that a randomly selected bag of Skittles has at least 37 Skittles is 0.25451
Option c) .253 is.correct
c) What is the probability that a randomly selected bag of Skittles has between 39 and 42 Skittles? a) .112 b) .232 c) .344 d).457 e).6125.
z = (x-μ)/σ
Mean of 38.4 and a standard deviation of 2.12.
For 39 Skittles
z = (39 - 38.4)/2.12
= 0.28302
Probability value from Z-Table:
P(x = 39) = 0.61142
For 42 Skittles
z = (42 - 38.4)/2.12
= 1.69811
Probability value from Z-Table:
P(x = 42) = 0.95526
The probability that a randomly selected bag of Skittles has between 39 and 42 Skittles is:
P(x = 42) - P(x = 39
0.95526 - 0.61142
0.34384
= 0.344
Option c is.correct
d) What is the percentile rank of a randomly selected bag of Skittles that has 40 Skittles in it? a)82nd b) 78th c) 75th d)25th e)22nd
z = (x-μ)/σ
Mean of 38.4 and a standard deviation of 2.12.
z = (40 - 38.4)/2.12
= 0.75472
P-value from Z-Table:
P(x = 40) = 0.77479
Converting to percentage = 0.77479× 100
= 77. 479%
≈ 77.5
Percentile rank = 78th
