A Solution of the equation,
3x2 + 2x + 1 = 0 is
Answer:
x = -3.5
Step-by-step explanation:
POE = PROPERTY OF EQUALITY
3*2 + 2x + 1 = 0
6 + 2x + 1 = 0 ## ^ Multiplication
7 + 2x = 0 ## ^ Combine like-terms
2x = -7 ## ^ Subtraction POE
x = -3.5 ## ^ Division POE
Answer:
X=0
Step-by-step explanation:
Use PEMDAS to get rid of some things. Do 3 x 2 = 6. Then distribute the like terms to one side seperating 2x and "0": +1 ---> 0-1 = -1. Now divide... 2x/2 = x (cancels out) and 0/2 = 0. Therefore X=0. But I'm not a computer so double check your answer.

Deon is playing fetch with his dog with a toy that is shaped like a circle. The circumference of the toy is 12π inches.
Which measurement is closest to the area of the toy in square inches?
18.84 in.²
37.68 in.²
113.04 in.²
452.16 in.²
Answer:
113.04
Step-by-step explanation:
The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex]
Given that,
Deon is playing fetch with his dog with a toy that is shaped like a circle,
The circumference of the sculpture is 12π inches.
We have to determine,
Which measurement is closest to the area of the toy in square inches.
According to the question,
Circumference of the circle = [tex]2\pi r[/tex]
Where, circumference = [tex]12\pi[/tex]
Then,
[tex]12\pi =2\pi r \\\\r = \dfrac{12\pi }{2\pi }\\\\r = 6\ inches[/tex]
Therefore,
Deon is playing fetch with his dog with a toy that is shaped like a circle.
Area of the circle = [tex]\pi r^{2}[/tex]
Where, r = 6inches
Then,
Area of the circle is given by,
[tex]= \pi r ^{2}\\\\= 3.14 \times (6)^{2}\\\\= 3.14 \times 36\\\\= 113.04\ inches^{2}[/tex]
Hence, The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex].

what is the product of 2 4/7 × 13/12
Answer:
2 11/14
Step-by-step explanation:
First make both of them improper fractions.
therefore,
2 4/7 = 18/7
now simplify.
18/7 × 13/12
18 and 12 get cancelled off as they're multiples of 3 and 6
therefore,
3/7 × 13/2
3× 13 = 39
7×2 = 14
39/14
now make it a proper fraction

A person Rents a canoe for 4 Hours and paid a total of $36. of Renting a canoe costs am initial fee of the $2 Plus an additional amount for each hour the canoe is rented,which graph represents the total cost,y, in dollars of renting a canoe for x hours
Answer:
Additional fee or hour = $8.5
y = $2 + 8.5x
Step-by-step explanation:
Given that :
Total paid = $36
Number of hours = 4
Initial rental fee = $2
Additional fee per hour = a
Total amount = initial rental fee + additional fee per hour * number of hours
36 = 2 + 4a
36 - 2 = 4a
34 = 4a
a = 8.5
Hourly fee = $8.5
Therefore, the cost formula
y = initial fee + regular fee * number of hours
y = $2 + 8.5x

Timothy bought groceries two days during the week: • Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday • Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday Which equation models the relationship between the cost of groceries after taxes, and the cost of groceries before taxes?
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.
We would solve this using direct proportion.
y = kx.
12.15 = 11.25k
k = 12.15 / 11.25
k = 1.08
Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.
y = kx.
59.13 = 54.75k
k = 59.13 / 54.75
k = 1.08
The equation that models the relationship will be:
y = 1.08x

Answer:
See the attachment for what goes on your X diagram.
Rewrite: x² -7x +4x -28
Grouping: (x² -7x) +(4x -28) = x(x -7) +4(x -7) = (x +4)(x -7)
Step-by-step explanation:
The given quadratic is ...
... x² -3x -28 . . . . . a=1, b=-3, c=-28
a) The value at the top of the X diagram is the product a·c = 1·(-28) = -28.
The value at the bottom of the X diagram is the coefficient b = -3.
The values on the sides of the diagram are the factors of -28 that add up to make -3. These are -7 and 4. That is, ...
(-7)·(4) = -28
(-7)+(4) = -3
b) Since the two values on the sides of the diagram add up to give "b", the value of "b" in the equation can be rewritten as the sum of these two numbers. Doing that, we have ...
... x² -3x -28
... = x² +(-7+4)x -28
... = x² -7x +4x -28 . . . . . . order does not matter. It could also be x² +4x -7x -28
c) We can group pairs of terms in the rewritten expression and factor each pair.
... = (x² -7x) +(4x -28) . . . . . first pair has a common factor of x; second pair, 4
... = x(x -7) +4(x -7) . . . . . . . these terms now have a common factor: (x -7)
... = (x +4)(x -7) . . . . . . . . . . the complete factorization of x² -3x -28

When a ≠ 1, there are a couple of additional steps. Effectively, you reduce the fractions ax/p and ax/q to a'x/p' and a''x/q'', then rewrite those as the factors (a'x+p')(a''x+q'') where the ' and '' numbers are after reducing the fractions. (The numbers may be the same as the original if the fraction cannot be reduced.) As a check, a'·a'' = a, and p'·q'' = c.
