For the values of x, the quadratic function f(x) = 3x² – 2x + 5 is satisfied. Then the correct option is B.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
At x = –2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–2)² – 2(–2) + 5
f(x) = 12 + 4 + 5
f(x) = 21
At x = –1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–1)² – 2(–1) + 5
f(x) = 3 + 2 + 5
f(x) = 10
At x = 0, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(0)² – 2(0) + 5
f(x) = 0 + 0 + 5
f(x) = 5
At x = 1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(1)² – 2(1) + 5
f(x) = 3 – 2 + 5
f(x) = 6
At x = 2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(2)² – 2(2) + 5
f(x) = 12 – 4 + 5
f(x) = 13

2)Using the properties of similar triangles, input the values that you know the measurements of and use properties of similar triangles to indirectly measure 5 objects of your own choice. Show your work.
Similar triangles may or may not have congruent sides lengths
How to determine the measurements of the objectsFrom the properties of similar triangles, the side lengths of similar triangles may or may not be congruent, but the side lengths are always proportional.
Take for instance, an equilateral triangle has a dimension of 2cm by 2cm by 2cm
The similar triangles could have the following dimensions:
3cm by 3cm by 3cm4cm by 4cm by 4cm6cm by 6cm by 6cm7cm by 7cm by 7cm10cm by 10cm by 10cmThis is so because the triangles are proportional to the equilateral triangle

a manufacturer sells an article to a wholeseller at a profit of 18%,the wholesaler sells it to a retailer at a profit of 20%.the retailer sells it to a customer at a profit of 25%.if the customer pays ₹30.09 for it,find the cost of the manufacturer
Answer:
the cost price of manufacturer = RS. 14.80
Step-by-step explanation:
the retailers profit = profit percent of sold amount
= 25% of 30.09
= 25/100 × 30.09
= 7.5225
here, the cost price of retailer =
sold amount- profit amount
or, CP = 30.09 - 7.5225
= 22.5675
now, profit of whole seller =
profit% of sold amount
or, 20% of SP
20/100 × 22.5675
= 4.5135
CP = SP - Profit
or, CP = 22.5675- 4.5135
CP = 18.054
now, profit of manufacturer = profit℅ of SP
= 18% of 18.054
= 18/100 × 18.054
= 3.24972
or, CP of manufacturer = SP - profit amount
= 18.054 - 3.24974
= 14.80428
Therefore, cost price of manufacturer = 14.80

Step-by-step explanation:
x^2 + 7x - 60 = 0
D = b^2 - 4ac
D = 7 * 7 + 60 * 4 * 1 = 289
sqrt(D) = sqrt(289) = 17

A group of 125 teenagers were asked which of the following activities they would most likely choose to spend their free time doing: reading a book, watching television, playing video games, or listening to music. The results are displayed in the circle graph below.
What is the difference in percent between those who chose reading a book and those who chose to listen to music?
a. 16%
b. 8%
c. 12%
d. 4%
Answer:
12%
Step-by-step explanation:
Read a book = 16%
Listen to music = 28%
We can read the question in different ways:
1. The simple difference between the two is 12%
2. Out of the sample, the two groups include:
15 chose books
35 chose music
Within this sample of 50 teenagers,
(15/50) or 30% chose books, and
(35/50) or 70% chose music
That makes a difference of 40%
I would chose the first interpretation, 12% [Especially since 40% is not an option.]

SUBTRACT 5 to BOTH SIDES
2/3x + 5 - 5 = 1 - 5
SIMPLIFY IT!
2/3x = 1 - 5
2/3x = -4
MULTIPLY 3/2 to BOTH SIDES
2/3x * 3/2 = -4 * 3/2
SIMPLIFY IT!
x = -4 * 3/2
x = -6
Therefore, your answer is: x = -6
Good luck on your assignment & enjoy your day!

Answer:
2/3x + 5=1
To solve for x, we must isolate it by administering inverse operations.
In this equation, we can see 2/3x is being added to 5.
We should discard the constants first.
The inverse operation of addition, is subtraction.
So we subtract 5 from both sides;
-5 -5
2/3x = -4
Now, we are left with a coefficient, so to get rid of the coefficient we utilize the inverse operation of multiplication, which is division.
Dividing by 2/3 is the same as multiplying by 3/2.
So multiply both sides by 3/2;
*3/2 *3/2
x = -4(3)/2
x = -12/2
x = -6
