Answer:
a
Step-by-step explanation:
Solving the inequality
[tex]\frac{x+3}{6}[/tex] > [tex]\frac{x}{4}[/tex] + 1
Multiply through by 12 ( the LCM of 6 and 4 ) to clear the fractions
2(x + 3) > 3x + 12
2x + 6 > 3x + 12 ( subtract 2x from both sides )
6 > x + 12 ( subtract 12 from both sides )
- 6 > x , that is
x < - 6
The only value less than - 6 is - 10
Thus x = - 10 is a solution to the inequality
Jada is making lemonade for a get-together with her friends. She expects a total of 5 to 8 people to be there (including herself). She plans to prepare 2 cups of lemonade for each person. The lemonade recipe calls for 4 scoops of lemonade powder for each quart of water. Each quart is equivalent to 4 cups. Let represent the number of people at the get-together, the number of cups of water, the number of scoops of lemonade powder. Select all the mathematical statements that represent the quantities and constraints in the situation.
Answers
Answer: B,C,D,F
Step-by-step explanation:
All the correct mathematical statements that represent the quantities and constraints in the given situation are;
Option B; 5 ≤ n ≤ 8
Option C; c = 2n
Option D; l = c
Option F; 10 ≤ l ≤ 16
We are told that;
n = the number of people
c = the number of cups
l = the number of scoops of lemonade powder.
We are told that number of people is a total of between 5 to 8 people. Thus, the inequality to represent this is; 5 ≤ n ≤ 8We are told that she wants to prepare 2 cups of lemonade for each person. This means when n = 1, c = 2 ; when n = 2, c = 4. Thus, this can be expressed as; c = 2nWe are told that the lemonade recipe calls for 4 scoops of lemonade powder for each quart of water. That means 4 lemonade powder scoops = 4 cups. This can be expressed as; 4l = 4c. This can be simplified to; l = c
Since she is expecting between 5 to 8 people including herself. 2 lemonade scoops per person means;
the least amount of lemonade = 5 × 2 = 10
the maximum lemonade = 8 × 2 = 16
This can be written in inequality form as;
10 ≤ l ≤ 16
The only options that correspond with all the inequalities gotten above are; Options B, C, D, F.

What is the nature of the roots for y=2x2-5?
Answers
Answer:
x=[tex]\sqrt5/2[/tex] , x = -[tex]\sqrt5/2\\[/tex]
Step-by-step explanation:
2x^2-5=0
add 5 to both sides
2x^2-5+5=0+5
2x^2=5
(2x^2/2) = 5/2
x^2=5/2
x=[tex]\sqrt5/2\\[/tex] , x = -[tex]\sqrt5/2[/tex]
To determine the nature of the roots of the quadratic equation y [tex]= 2x^2 - 5[/tex], we can analyze its discriminant (denoted by Δ).
The discriminant is calculated using the formula Δ [tex]= b^2 - 4ac,[/tex] where a, b, and c represent the coefficients of the quadratic equation in the standard form [tex]ax^2 + bx + c = 0.[/tex] For the given equation, a [tex]= 2,[/tex] b [tex]= 0,[/tex]and c [tex]= -5.[/tex]Plugging these values into the discriminant formula, we have: Δ [tex]= 0^2 - 4(2)(-5) Δ = 0 + 40 Δ = 40[/tex]The discriminant is positive, indicating two distinct real roots.
Since the discriminant is greater than zero, we can conclude that the roots of the equation are real and different. Therefore, the nature of the roots for y[tex]= 2x^2 - 5 i[/tex]s that it has two distinct real roots.

What is x equal to? And what is the scale factor?
Answers
Answer:
1. 225 km
2. 95 km
3. 412.5 km
Step-by-step explanation:
For this one, it is saying that for every 2 cm, that is 50 km. So if you look at 9 cm, you can divide that by 2 cm to get 4.5 cm, this is what you can multiply by 50 km to get 225. Or you can look at it this way, for every 1 cm, the actual distance is 25 km. Then you can multiply each value by 25 to get your answer. Whichever one works for you.

Explanation:
The smaller angles AOB and BOC combine to the largest angle AOC
By the angle addition postulate, we can say,
(angleAOB) + (angleBOC) = (angleAOC)
(3x+4) + (8x-28) = 108
11x-24 = 108
11x = 108+24 .... adding 24 to both sides
11x = 132
x = 132/11 .... dividing both sides by 11
x = 12
We can use this x value to find each angle
angle AOB = 3x+4 = 3*12+4 = 40 degrees
angle BOC = 8x-28 = 8*12-28 = 68 degrees
As a check,
(angleAOB)+(angleBOC) = (40)+(68) = 108
which matches with the measure of angle AOC. This confirms our answers.
Answer:
[tex]AOB = 40[/tex]
Step-by-step explanation:
[tex]AOC = 108 \\
AOB = 3x + 4 \\
BOC = 8x - 28 \\ but \: AOB +BOC =AOC \\ 3x + 4 + 8x - 28 = 108\\ 11x = 132 \\ x = 12\\ AOB = 3x + 4 = 3(12) + 4 \\ AOB = 40[/tex]

Work out
e-f
Simplify your answer.
Answers
Answer:
12+2d
Step-by-step explanation:
e=5+d
f=d-7
e-f = 5+d-(d-7)
e-f = 12+2d
The solution of expression e - f is,
⇒ e - f = 12 + 2d
We have to given that,
e is 5 more than d.
And, f is 7 less than d.
Hence, It can be written as,
e is 5 more than d.
⇒ e = 5 + d
And, f is 7 less than d.
⇒ f = d - 7
So, We get;
e - f = (5 + d) - (d - 7)
Combine like terms,
e - f = 12 + 2d
Therefore, The solution of expression e - f is,
⇒ e - f = 12 + 2d
