What substitution should be used to rewrite 6(x + 5)2 + 5(x + 5) – 4 = 0 as a quadratic equation?
- (x+5)
- (x - 5)
Ou-(x + 5)2
u = (x - 5)2
Answer:
x+5 is replaced
Step-by-step explanation:
6(x + 5)^2 + 5(x + 5) – 4 = 0
Replace x+5 with m
6(m)^2 + 5(m) – 4 = 0
Now this is a quadratic equation
The required substitution is (x + 5) to rewrite 6(x + 5)² + 5(x + 5) - 4 = 0 as a quadratic equation. The correct answer is A. (x+5).
What is a quadratic equation?The quadratic equation is defined as a function containing the highest power of a variable is two.
The quadratic equation is given as follows:
6(x + 5)² + 5(x + 5) - 4 = 0
Let u = x + 5. Then, we can rewrite the equation 6(x + 5)² + 5(x + 5) - 4 = 0 as:
6u² + 5u - 4 = 0
This is now a quadratic equation in u, which can be solved using the quadratic formula or factoring.
Once we find the solutions for u, we can substitute back u = x + 5 to get the solutions for x.
Therefore, the correct answer is A. (x+5).

Choose yes or no to tell whether there is more than one way to draw a triangle with the given measures
AB= 15 cm, BC=20 cm, angle B=40 degrees
AB=20 cm, AC=15 cm, angle c=40 degrees
BC=10 cm, AB=5 cm, angle A=20 degrees
AC=5 cm, BC=10 cm, AB=14 cm
Question:
1) AB = 15 cm, BC = 20 cm, angle B = 40°
2) AB = 20 cm, AC = 15 cm, angle c = 40°
3) BC = 10 cm, AB = 5 cm, angle A = 20°
4) 5 cm, BC = 10 cm, AB = 14 cm
Answer:
1) No: SAS
2) Yes: SSA
3) Yes: SSA
4) No: SSS
Step-by-step explanation:
To answer the question, we note that a well defined triangle or unique provides information for;
a. SSS All three sides
b. Side Angle Side, SAS Two sides and the included angle(the angle between the two sides), such that there is only one way to draw the triangle
c. Angle Side Angle, ASA and
d. Angle Angle Side, AAS
We analyse each option as follows
1) AB = 15 cm, BC = 20 cm, angle B = 40°
No:
The provided information includes two sides and the angle between the two sides, therefore there is only one way to draw the triangle
2) AB = 20 cm, AC = 15 cm, angle c = 40°
Yes
Here the provided information are SSA hence there are more than one way to draw the triangle
3) BC = 10 cm, AB = 5 cm, angle A = 20°
Yes
Here the provided information are Angle Side Side hence there are more than one way to draw the triangle
4) 5 cm, BC = 10 cm, AB = 14 cm
No
Here the provided information is SSS hence, there is only one way to draw the triangle
Given that the discriminant of a quadratic equation is 8, determine the number of real solutions.
Answer:
There are two real solutions.
Step-by-step explanation:
There are only three possible solutions for the discriminant of a quadratic equation:
1. D < 0
In this case there are no real solutions. The graph does NOT intersect with the x-axis.
2. D = 0
In this case there is exactly one real solution. The graph touches the x-axis in one point, which is called the Top.
3. D > 0
In this case there are two real solutions. The graph intersects the x-axis in two points.
Your soccer team wants to practice a drill for a certain amount of time each day. Which plan will give your team more total practice time over 4 days? Over 8 days? Explain your reasoning.
Answer:
plan 1
Step-by-step explanation:
plan 1: 5 + 6 + 7 + 8 = 26min 8 days: 68
plan 2: 1 + 2 + 3 + 4 = 10min 8 days: 36
Answer:
The answer would be plan two since it would double each day, making it a lot larger than Plan 1.
Step-by-step explanation:
So first, to understand this, 0 is today, and then I did this based on 4 days and 8 days after what is represented as "today."
Plan 1:
[tex]y=5+1x[/tex]
Day 4:
[tex]y=5+1(4)\\y=5+4\\y=9[/tex]
Day 8:
[tex]y=5+1(8)\\y=5+8\\y=13[/tex]
Plan 2:
[tex]y=2^{x}[/tex]
Day 4:
[tex]y=2^{4} \\y=2*2*2*2\\y=4*2*2\\y=8*2\\y=16[/tex]

Answer:
No Mr.Linton will not take 7 days to finish the book
Explanation
Since the book has 900 pages, you will have to divide 900 by 100 which equals 9. 9 is the number of days it will take for Mr.Linton to read the book. Therefore he is wrong.

Agnes heard that as a general rule, she should spend no more than 30% of her take- home pay on rent. If Ange’s take-home pay is $39,600 per year, what is the maximum amount per amount per month that the should spend on rent ?
Answer:
990
Step-by-step explanation:
The maximum monthly rent payment that should be made is $1990.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, Agnes heard that as a general rule, she should spend no more than 30% of her take-home pay on rent.
Since her salary is $39,600
Thus,
She should not pay rent of more than = 39,600 * 30%
She should not pay rent of more than = 11,880
He maximum rent per month= 11,880/12 = 990
Therefore, the maximum amount per month that she should spend on rent is $990.

You are going to a baseball game and you love to eat salted peanuts while watching the game. You know that you can buy peanuts there, but you know its cheaper to bring your own. When you go to the grocery store to buy some, you see two choices: $3.59 for a 20 oz bag of salted peanuts or $2.59 per pound for loose salted peanuts.
Answer:
I am assuming you are asking which is the cheaper option per ounce since you did not specify a question.
Option 1: 3.59$ for a 20 oz bag
3.59/20=.1795 $/oz
Option 2: 2.59 per 1 pound
1 pound = 16 oz
2.59/16= .161875 $/ozo
Since .16 dollars is less than .18 dollars, the second option, where 1 pound costs $2.59, is cheaper.

Trust me i got it right on Khan Academy
The required equation of vertical line pass through (2, 3) is x = 2.
Equation of the vertical line to be determine which passes through (2,3).
A line can be defined by a shortest distance between two points is called as a line.
Slope of the vertical line is infinite. i.e. m = 1/0
Here, with point (2,3) equation of the line.
y-3= 1/0 (x-2)
(y-3)0 = x-2
x-2 = 0
x = 2
Thus, the required equation of vertical line pass through (2, 3) is x = 2.

Veronica has received a $3,000 gift and is looking for a bank to start a savings account. Which option would be the best for her if the current inflation rate is 2.5%?
A. bank that offers 4% interest
B. bank that offers 3% interest
C .bank that offers 2.5% interest
D. bank that offers 3.5% interest
Answer:
A
Step-by-step explanation:
You are looking for the highest real interest rate, which is the nominal rate minus the inflation rate. With that being said, the lowest interest rate is 2.5%, which wouldn't make her anything. However, the 4% interest rate yields 1.5% real interest, making it the best option.
The best investment option is the option (A), where the interest rate is 4% which is higher than other options.
What is the interest rate?The amount a lender charges a borrower, expressed as a percentage of the principle, is known as the interest rate.
Given that, the current inflation rate is 2.5%.
Therefore, to make a profitable investment, the interest rate should be more than the inflation rate.
The higher interest rate will give a higher profit.
Therefore, the best investment option is an option (A), where the interest rate is 4% which is higher than other options.

Find the coordinates of the vertices of the figure formed by each system of inequalities. x + y < 9 x - 2y < 12 y < 2x + 3 a. (0, 0), (0, 1), (2, 0) c. (9, 1), (2, 3), (5, 6) b. (10, -1), (-6, -9), (2, 7) d. (0, -1), (2, -1), (3, 6)
Answer:
b. (10, -1), (-6, -9), (2, 7)
Step-by-step explanation:
One way to solve this problem is by graphing (see attachment). In fact, that actually is the easiest way to do this.
First, graph x + y < 9 (red part on the attachment). To do this, isolate the y so that it's like a regular linear equation: y < -x + 9. Graph the line y = -x + 9 first, and then choose a point either on the left or right of the line to plug in for x and y.
Let's just choose (0, 0), which is on the left of the line: 0 < -0 + 9 ⇒ 0 < 9. Since this is a true statement, we know that we should shade the left side of the equation, and not the right side.
Now, graph x - 2y < 12 (blue part on the attachment). It's the same process here as the first inequality. For this one, we find that we also shade to the "left" of the line (it's more "up" than "left", but you get the idea).
Finally, graph y < 2x + 3 (green part on the attachment). Again, it's the same process. For this, we shade to the right.
Now look at the three points that they intersect at: they are (2, 7), (-6, -9), and (10, -1). The answer is thus B.
Step-by-step explanation:
Step 1: Graph each of the inequalities
x + y < 9
x - 2y < 12
y < 2x + 3
It comes out that the vertices are (2, 7), (10, -1), and (-6, -9)
