Answer:
3x^22−x^2+3
Step-by-step explanation:
Let's simplify step-by-step.
3x^22+2x+4−(x2+2x+1)
Distribute the Negative Sign:
=3x^22+2x+4+−1(x2+2x+1)
=3x^22+2x+4+−1x2+−1(2x)+(−1)(1)
=3x&22+2x+4+−x2+−2x+−1
Combine Like Terms:
=3x22+2x+4+−x2+−2x+−1
=(3x22)+(−x2)+(2x+−2x)+(4+−1)
=3x22+−x2+3
Answer:
=3x22−x2+3

Lines QS and NR intersect at P. Ray PM is perpendicular to line SQ.
What is the value of y?
Answer:
A. 13
Step-by-step explanation:
[tex] (6y - 14) + 90 + (2y) = 180 [/tex] (angles on a straight line)
Solve for y
[tex] 6y - 14 + 90 + 2y = 180 [/tex]
Collect like terms
[tex] 6y + 2y - 14 + 90 = 180 [/tex]
[tex] 8y + 76 = 180 [/tex]
Subtract 76 to both sides
[tex] 8y + 76 - 76 = 180 - 76 [/tex]
[tex] 8y = 104 [/tex]
Divide both sides by 8
[tex] \frac{8y}{8} = \frac{104}{8} [/tex]
[tex] y = 13 [/tex]

Choose all the expressions that are equal to 0.7 × 0.41.
A. 7100×41100
B. 710×41100
C. 7100×4110
D. 710×4110
E. 70100×41100
Answer:
None of the expressions is equal to 0.7 x 0.41.
Step-by-step explanation:
Given that 0.7 x 0.41 is equal to 0.287, to determine which options are equal to said operation, the calculations set out for each of them must be performed:
A. 7,100 × 41100 = 291,810,000
B. 710 × 41100 = 29,181,000
C. 7100 × 4110 = 29,181,000
D. 710 × 4110 = 2,918,100
E. 70100 × 41100 = 2,918,100,000
Therefore, looking at all the results produced by the predisposed calculations, it is evident that none of the expressions is equal to 0.7 x 0.41.
There is no expression equivalent to the given expression and this can be determined by using the arithmetic operations.
Given :
Expression -- 0.7 × 0.41
The arithmetic operations can be used in order to evaluate the given expression.
[tex]0.7\times 0.41 = 0.287[/tex]
Now, check all the options in order to determine the correct option.
A) 7100×41100
Evaluate the above expression by using the arithmetic operations.
[tex]7100\times 41100 = 291810000[/tex]
Therefore, this option is incorrect.
B) 710×41100
Evaluate the above expression by using the arithmetic operations.
[tex]710\times 41100 = 29181000[/tex]
Therefore, this option is incorrect.
C) 7100×4110
Evaluate the above expression by using the arithmetic operations.
[tex]7100\times 4110 = 29181000[/tex]
Therefore, this option is incorrect.
D) 710×4110
Evaluate the above expression by using the arithmetic operations.
[tex]710\times 4110 = 2918100[/tex]
Therefore, this option is incorrect.
E) 70100×41100
Evaluate the above expression by using the arithmetic operations.
[tex]70100\times 41100 =2881110000[/tex]
Therefore, this option is incorrect.

(Transformations, Quadratic functions)
I know how to solve for the x but I'm confused on solving for the Y. Thank you!
Answer:
the other answer is zero.
Step-by-step explanation:
Step 1: Use the vertex form, [tex]y=a(x-h)^2+k[/tex], to determine the values of a, h, and k. The "k" value is always the "y" value in a ordered pair. Since there is no "k" value, the "k" value will just be zero. In turn, since the "k" value is zero... so will the "y" value be zero.
[tex]a=8\\\\h=21\\\\k=0[/tex]

Answer:
40
Step-by-step explanation:
The parallelograms are similar, so their corresponding sides are proportional. Write a proportion:

Solve for PQ:
PQ = 40
si sna es 12 años menor que eva y dentro de 7 años la edad de eva es el doble que la edad de ana que edad tiene eva
Responder:
17
Explicación paso a paso:
Dejar ;
Edad de Eva = x
Edad de Ana = x - 12
Dentro de los 7 años de la edad de Eva, la edad de Ana será el doble
x + 7 = 2 (x - 12 + 7)
x + 7 = 2 (x - 5)
x + 7 = 2x - 10
x - 2x = - 10 - 7
-x = - 17
x = 17
Por lo tanto, Eva tiene 17 años.

All swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45. Find the discount.
The discount is $18 if the all swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
We have:
All swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45.
The regular price = $45
The discount is worth = 40% of 45
= (40×45)/100
= $18
Thus, the discount is $18 if the all swimming equipment is on sale with a 40% discount. A snorkeling set regularly sells for $45.

Mr. Hickman's cherry tree grew 12 inches in of a year. At that rate,
4
how much would it grow in 1 year?
Answer:
At the given rate, Mr. Hickman's cherry tree would grow 16 inches in 1 year.
Step-by-step explanation:
I assume the actual question is:
"Mr. Hickman` s cherry tree grew 12 inches in 3/4 of a year. How much would it grow in one year ?"
As stated,
In 3/4 of a year, Mr. Hickman's cherry tree grew = 12 inches
Therefore,
In 1 year, Mr. Hickman's cherry tree would grow = [tex]\frac{1}{\frac{3}{4} }*12[/tex] inches
= 4/3 * 12 inches
= 16 inches
Hence, at the given rate, Mr. Hickman's cherry tree would grow 16 inches in 1 year.

A vaccine, which is currently in use, is known to be 80% effective. A pharmaceutical company has developed a newvaccine and the company claims that 90% of the people given the new vaccine will develop the immunity. Supposethe claim of the company is true, and the newly developed vaccine is given to 20 people. The expected number of people in the sample that will develop the immunity is:__________ a) 90% b) 18% c) 16% d) 80%
Answer:
The correct answer is B) 18%
Step-by-step explanation:
Note that the vaccine is already and is 80% effective. This means that if the entire population was administered with the vaccine, only 8/10 would gain immunity leaving 2/10 or 0.2 exposed.
If the new vaccine, therefore, is supposed to be 90% effective, it is only pragmatic to administer it against those who do not have immunity which is 0.2 of the existing population.
So to get the percentage that will develop immunity, we have:
0.2 x 0.9 = 0.18 or 18%

Denise bought 5.2 pounds of rice for $5.29. Using the unit rate, how much would 2 pounds of rice cost? A $1.02 C $2.04 B $1.29 D $6.31
Answer:
it's A
Step-by-step explanation:
Answer:
C. $2.04
Step-by-step explanation:
Because we see that 5.2 pounds is $5.29, roughly around 5.2, we can infer that 2 pounds of rice would equal just a little bit over $2, and the only logical answer would be $2.04.

Check all the equations that apply to meet the Segment Addition Postulate in segment OQ. OP = 6x + 5, PQ = 4x and OQ = 45.
Answer:
[tex]6x + 5 + 4x = 45[/tex]
[tex]10x = 40[/tex]
Step-by-step explanation:
Given
[tex]OP = 6x + 5[/tex]
[tex]PQ = 4x[/tex]
[tex]OQ = 45[/tex]
The given parameters show that P is a point between O and Q.
So:
[tex]OQ = OP + PQ[/tex]
Substitute values for OP, PQ and OQ
[tex]45 = 6x + 5 + 4x[/tex]
[tex]6x + 5 + 4x = 45[/tex] --- This is an equation
Collect Like Terms
[tex]6x + 4x = 45 - 5[/tex]
