Find the solution set of given inequality. Pls answer fast its urgent. I will give 90 points to the person who will answer it and also mark his answer as brainliest
Answers
Answer:
x ≥ 5
Step-by-step explanation:
5 + 2(2x - 3) ≥ 3x + 4
Expand brackets:
⇒ 5 + 4x - 6 ≥ 3x + 4
Combine like terms:
⇒ 4x - 1 ≥ 3x + 4
Subtract 3x from both sides:
⇒ x - 1 ≥ 4
Add 1 to both sides:
⇒ x ≥ 5
Answer: x>=5
Step-by-step explanation:
Simplify the expression
5+2\cdot\left(2x-3\right)>=3x+4
5+2\cdot2x+2\cdot-3>=3x+4
5+4x-6>=3x+4
4x+\left(5-6\right)>=3x+4
4x-1>=3x+4
Group all r terms on the left side of the inequality
x-1>=4
x-1+1>=4+1
x>=4+1
x>=5

Therefore, x = 1.5

My first number is -2. my fifth number is 26.
-2

What is my third number?
Answers
Step-by-step explanation:
equal steps.
so, starting at -2 the fifth number (= after the 4th step) is 26.
so, the interval is 26 - -2 = 28 long.
28/4 = 7
so, each step is 7 long.
the third number is after the second step, that means after adding 2×7 = 14
-2 + 14 = 12
12 is the third number.

Answers
Answer:
Step-by-step explanation:
f(x) = x⁴ - 8x² + 16
f'(x) = 4x³ - 16x = 4(x³ - 4x) = 4x(x² - 4) = 4x(x - 2)(x + 2)
f'(x) = 0, x = 2, -2
f"(x) = 4(3x² - 4)
f''(0) = -16 < 0, f""(2) = f''(-2) 3(12 - 4) > 0
so f(2) and f(-2) are minimum values
f(0) is maximum value.
f(0) = 16, f(2) = f(-2) = 2⁴ - 8*2² + 16 = 0
Maximum = 16, minimum value = 0
-∞ < x < -2, f'(x) < 0
-2 < x < 0, f'(x) > 0
0 < x < 2, f'(x) < 0
2 < x < ∞, f(x) > 0
increase: (-2, 0) and (2, ∞)
decrease: (-∞, -2) and (0, 2)

The price of an item has been reduced by 60%. The original price was $34.
Use the ALEKS calculator to find the price of the item now.
Answers
Answer:
$13.60 cents
Step-by-step explanation:
Given the following question:
60% of 34
In order to find the answer, we will use the formula to calculate percentages to find 60% of 34. Once we find that answer we will subtract it from the initial amount.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{60\times34}{100} =60\times34=2040\div100=20.4[/tex]
[tex]=20.40[/tex]
Now subtract:
[tex]34-20.40=13.60[/tex]
[tex]=13.60[/tex]
After a 60% discount the item will cost "$13.60 cents."
Hope this helps.
can anyone help? Estimate the amount of the tip by rounding the bill to the nearest dollar before calculating.
20% tip on a bill of $64.15
Answers
Answer:
$12.80
Step-by-step explanation:
You are asked to estimate the tip by rounding the bill amount. The tip is the product of the (rounded) bill amount and the tip rate.
rounded bill = $64.00
tip rate = 20% = 0.20
estimated tip = 0.20 × $64.00 = $12.80

9. Elijah had three sets of five marbles. He gave 6 marbles to his sister and had three sets of three marbles left. What does the equation look like?
3x (5 - 6) = 3 x 3
3 x 5 - 6 = (3x3)
• (3×5) – 6= 3x3
(3x6) - 5 = 3x3
Answers
Answer:
(3x5) -6 = 3x3
Step-by-step explanation:
So we know that elijah starts with 3 sets of 5 marbles each.
This can be thought of as 3 x each set, or 3 x 5.
Elijah then gives away 6 marbles from this set, or in other words subtracts 6.
How can this be put into a equation, however?
We know that we are taking 3x5, and subtracting it by 6. However it isnt as simple as 3x5-6.
It would have to be (3x5)-6, since your sets are a total of 15, or 3x5. This total is being subtracted to by 6.
This can be written as:
(3x5)-6
The only equation in your list that looks like this would be the third one, where:
(3x5)-6 = 3x3
So this would be your answer!
Hope this helps! :3

Convert them to improper fractions by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, then putting it over the denominator:
[tex]2 \frac34 + 3\frac34=\dfrac{2 \times 4+3}{4}+\dfrac{3 \times 4+3}{4}=\dfrac{11}{4}+\dfrac{15}{4}[/tex]
As the fractions have the same denominator, we can simply add the numerators:
[tex]\dfrac{11}{4}+\dfrac{15}{4}=\dfrac{11+15}{4}=\dfrac{26}{4}[/tex]
Convert back to a mixed number by dividing the numerator by the denominator. Writing the whole number followed by the remainder over the denominator:
[tex]\dfrac{26}{4}=6\frac24=6\frac12[/tex]

Can you use the elimination method please? Thx
Answers
Answer:
150
Step-by-step explanation:
So I will shorten Eric, and Bob's names as E, and B.
So the equations are this
B-E = B+E - 240, E as Eric, and B as Bob, and this E+B=9(E-B)
Move the variables and you get
-2E =- 240
Just divide them both by -2
and E=120
So when we know the value of E we can just plug it into the 1st question
120+B=9B+1080
Moves the Variables and numbers to the other side
8B=1200
1200/8= 150
B=150
There is Bob's weight

Part A: The Grand Prismatic Spring in Yellowstone discharges 8,400 gallons of water at a rate of 560 gallons a minute. Using m for minutes, write an equation that represents this situation.
Part B: video (0:28-0:43) Using the equation you wrote in Part A, how many minutes does it take for 8,400 gallons of water to discharge? Use 1-2 sentences to explain your answer.
Part C: video (0:28-0:43) How many gallons of water are left in the Spring after 7 minutes? Use 1-2 sentences to explain how you determined this amount.
Part D: video (0:44-1:17) Using the Mohs scale of hardness as outlined in the video, if Feldspar is three times as hard as cardboard,c, write an equation and solve to find the hardness scale of cardboard. Use 1-2 sentences to explain the hardness scale of cardboard and how it relates to Feldspar.
Answers
a) The equation [tex]V(m) = 8400 - 560\cdot m[/tex] represents the discharge of the Grand Prismatic Spring.
b) The discharge of the Grand Prismatic Spring takes 15 minutes.
c) The remaining quantity after 7 minutes is 4480 gallons.
d) The hardness of cardboard is 2.
How to apply concepts of linear functions
a) In this case, the volume of water ([tex]V[/tex]), in gallons, decreases linearly in time ([tex]m[/tex]), in minutes. Then, we could model the situation by using the following expression:
[tex]V(m) = V_{o} - \dot V \cdot m[/tex] (1)
Where:
[tex]V_{o}[/tex] - Initial volume, in gallons.[tex]\dot V[/tex] - Discharge rate, in gallons per minute.If we know that [tex]V_{o} = 8400\,gal[/tex] and [tex]\dot V = 560\,\frac{gal}{min}[/tex], then the volume of the Grand Prismatic Spring is represented by this expression:
[tex]V(m) = 8400 - 560\cdot m[/tex] (2)
The equation [tex]V(m) = 8400 - 560\cdot m[/tex] represents the discharge of the Grand Prismatic Spring. [tex]\blacksquare[/tex]
b) By (1) and [tex]V(m) = 0[/tex] we find the time required for discharge:
[tex]m = \frac{0 - 8400}{-560}[/tex]
[tex]m = 15\,min[/tex]
The discharge of the Grand Prismatic Spring takes 15 minutes. [tex]\blacksquare[/tex]
c) The quantity of gallons remaining is found by evaluating the function for [tex]m = 7[/tex]:
[tex]V(7) = 8400 - 560\cdot (7)[/tex]
[tex]V(7) = 4480\,gal[/tex]
The remaining quantity after 7 minutes is 4480 gallons. [tex]\blacksquare[/tex]
d) According to Mohs scale, the hardness of feldspar is 6. The statement indicates the following relationship, as there is a constant relationship between both hardnesses:
[tex]y = 3\cdot x[/tex] (3)
Where:
[tex]x[/tex] - Hardness of cardboard.[tex]y[/tex] - Hardness of feldspar.
If we know that [tex]y = 6[/tex], then the hardness of cardboard is:
[tex]x = \frac{6}{3}[/tex]
[tex]x = 2[/tex]
The hardness of cardboard is 2. [tex]\blacksquare[/tex]
