7x2+6=23x
a. What is the first step when solving this quadratic equation?
b. What are the solutions to the equation?
Answer:
x = 3, x = [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
(a)
The first step is to subtract 23x from both sides, that is
7x² - 23x + 6 = 0 ← in standard form
(b)
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 7 × 6 = 42 and sum = - 23
The factors are - 21 and - 2
Use these factors to split the x- term
7x² - 21x - 2x + 6 = 0 ( factor the first/second and third/fourth terms )
7x(x - 3) - 2(x - 3) = 0 ← factor out (x - 3) from each term
(x - 3)(7x - 2) = 0
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
7x - 2 = 0 ⇒ 7x = 2 ⇒ x = [tex]\frac{2}{7}[/tex]
A statistical hypothesis testing procedure is conducted over 5000 patients about some health intervention. The p-value is 0.02. Which is true? Group of answer choices If the null hypothesis was true, the probability of observing a difference at least as large as the observed diference would be 2% the probability of observing a difference at least as large as the observed diference is 2%
Answer:
The answer is "The first choice"
Step-by-step explanation:
In the given question the first choice is correct because When the zero assumption was valid, it would have been at least as bad to also be 2% to demonstrate a discrepancy as observed difference.

Please help me with this problem!!
15 m/s in km/h plz help
Answer:
54 km/h
Step-by-step explanation:
Step one:
given data
We are required to perform unit from m/s km/h
from 15m/s to km/h
Step two:
1 meter= 1/1000 km,
1 seconds= 1/3600 hour
1m/s = 1/1000/1/3600= km/h= 3600/1000= 36/10= 18/5 km/h
so of 1m/s is equivalent to 18/5 km/h
then 15m/s is equivalent to x
cross multiply
x= 15*18/5
x= 3*18
x=54 km/h
Please answer helpppp !!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!
Answer:
Step-by-step explanation:
Remember that TR is 1/3 the length of MR
MR = 54

Solve for u .
-3 (-6u+6) - u = 2 (u-6) - 1
Answer: U = 18
Step-by-step explanation:
U in (-oo:+oo)
U/(-6)+2 = -1 // + 1
U/(-6)+1+2 = 0
3-1/6*U = 0 // - 3
-1/6*U = -3 // : -1/6
U = -3/(-1/6)
U = 18
U = 18
Answer:
-3 (-6u+6) - u = 2 (u-6) - 1
18u -18 -u = 2u -12 -1
18u-u-2u=-12-1+18
15u= 5
u =5/15 = 1/3

Step-by-step explanation:
What is the value of a if a is equal to a×a×a=a+a+a
Answer:
a = ±sqrt(3)
Step-by-step explanation:
a×a×a=a+a+a
Simplifying each side
a^3 = 3a
Divide each side by a
a^3 /a = 3a/a
a^2 = 3
Take the square root of each side
sqrt(a^2) = ±sqrt(3)
a = ±sqrt(3)
Answer:
nope its not equal
a×a×a=a³, but a+a+a=3a
so, a³≠3a

sum of the series:
13, 16, 19, ..., 301
how many numbers are in this series?
Answer:
97
Step-by-step explanation:
13,16,19,...,301
a=13
d=16-13=3
l=a+(n-1)d
301=13+(n-1)3
301-13=(n-1)3
(n-1)3=288
n-1=288/3=96
n=96+1=97

Nora has nn nickels and dd dimes. She has a minimum of $2 worth of coins altogether. Write this situation as an inequality.
Answer:
0.05nn + 0.10dd ≥ 2
*make sure it is either n or nn depending whether you had a typo in problem*
Step-by-step explanation:
First each nickel is worth 0.05
each dime is 0.10
and we must have a minimum so the total value has to be at least $2
so 0.05nn + 0.10dd ≥ 2

Answer: 36
Step-by-step explanation:
Sry I got 12 but I changed it since 36 is correct
Answer:
36
Step-by-step explanation:
( 3 * 2 ) ^(2)
Remember the order of operations;
1. Parenthesis
2. Exponents
3. Multiplication or Division
4. Addition or subtraction
( 3 * 2 ) ^ (2)
Simplify what is in parenthesis first.
(6)^(2)
Now simplify the exponent. Remember, the power or the degree to which the base is at is telling one the number of times one needs to multiply the base by itself;
36

select the correct answer for x, each answer is rounded to the nearest tenth.
Answer:
x ≈ 27.2
Step-by-step explanation:
Using the sine ratio in the right triangle
sin54° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{22}{x}[/tex] ( multiply both sides by x )
x × sin54° = 22 ( divide both sides by sin54° )
x = [tex]\frac{22}{sin54}[/tex] ≈ 27.2 ( to the nearest tenth )
The average time a human being can hold their breath underwater is 1 minute. A hippo can hold its breath underwater for at least 5 times as long as a human. Write an inequality that represents how long a hippo can hold its breath underwater.
Answer:
Average breath hold time by hippo under water ≥ 5 minutes
Step-by-step explanation:
Average time by human = 1 minute
Average time by hippo = ≥ 5 times human
Since average human breath hold time = 1 minute
Average breath hold time by hippo = 5 * 1 minute
Average breath hold time by hippo under water ≥ 5 minutes
