I=
y =
Answer: x=0 y=-3
Step-by-step explanation: Hope this help
Answer:
y= -3
hope this helps!
Step-by-step explanation:
5y + 6x = 15 y + x = 3 Solve by Substitution : // Solve equation for the variable x x = y + 3 // Plug this in for variable x in equation 6• (y +3) - 5y = 15 y = -3 // Solve equation for the variable x.
Log3 (x squared + 7x + 21) = 2
Step-by-step explanation:
log <base a> b = x
means
a^x = b
So
3^2 = x^2+7x+21
x^2 + 7x + 21 - 9 = 0
x^2 + 7x + 12 = 0
(x+3)(x+4)
x = -3 or -4
The required solution given equation is x = -3 or -4.
What is logarithm?The logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.
Given:
The given equation is
[tex]Log 3 (x^{2} + 7x + 21) = 2[/tex]
According to given question we have
By the formula of logarithm we get
[tex]log_{a} b = x\\\a^x = b\\So\\3^2 = x^2+7x+21\\x^2 + 7x + 21 - 9 = 0\\x^2 + 7x + 12 = 0\\(x+3)(x+4)\\x = -3 or -4[/tex]
Therefore, the required solution given equation is x = -3 or -4.

Answer:
top one: (7b + 6)(7b - 6)
Step-by-step explanation:
the square root of 49b² = 7b
the square root of 36 = 6
you have to have one factor contain +6 and the other -6 so that, when you 'foil', the middle terms cancel out; and the 36 is negative
49b² - 42b +42b - 36 = 49b² - 36

Sarah has a savings account with $6,000 in it that earns 5.6% simple interest per year.
How much money, to the nearest penny, will Sarah have in 3 years? Give your answer in dollars.
Answer:
$7,008
Step-by-step explanation:
A = P(1 + rt)
P = $6000
r = 0.056 (percent in decimal form)
t = 3 years
A = 6000(1 + (0.056)(3))
A = 6000(1 + 0.168)
A = 6000(1.168)
A = $7,008
In a study by the Department of Transportation, there were a total of 95 drivers that were pulled over for speeding. Out of those 95 drivers, 33 were men who were ticketed, 8 were men who were not ticketed, 7 were women who were ticketed, and 47 were women who were not ticketed. Suppose one person was chosen at random.
1. What is the probability that the selected person is someone who was not ticketed, given it is a woman?
2. What is the probability that the selected person is someone who was not ticketed, given it is a man?
Enter your answers as whole numbers or fractions in lowest terms.
Answer:
1) 47/54 probability that the selected person is someone who was not ticketed, given it is a woman.
2) 8/41 probability that the selected person is someone who was not ticketed, given it is a man.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
1. What is the probability that the selected person is someone who was not ticketed, given it is a woman?
7 + 47 = 54 total woman
47 were not ticketed. So
[tex]p = \frac{47}{54}[/tex]
47/54 probability that the selected person is someone who was not ticketed, given it is a woman.
2. What is the probability that the selected person is someone who was not ticketed, given it is a man?
33 + 8 = 41 men.
8 were not ticketed. So
[tex]p = \frac{8}{41}[/tex]
8/41 probability that the selected person is someone who was not ticketed, given it is a man.

Pippi sold ten more cups of lemonade that cups of iced tea. She sold 120 cups in all. How many cups of lemonade did she sell?
Answer:
65 cups
Step-by-step explanation:
If she sold 10 more cups of lemonade than tea and sold 120 cups total. I first would subtract 10 cups from 120 =110. then I divide 110 /2 = 55 cups
The 55 cups makes it equal then I add the 10 cups back to the Lemonade to get 55+10 = 65
So your answer would be 65 cups of lemonade

What is the third angle of a triangle whose 1st angle is 34 and 2nd angle is 101 I meant sorry lol
Answer:
The third angle is 55 degrees.
Step-by-step explanation:
1) The three angles of a triangle always add up to 180 degrees. So, add together 34 + 101 = 135.
3) Then, subtract 180 - 135 = 55 degrees, and this is the missing angle!
I hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck on your assignment. :)
Answer:
Hi, I think it's 55 degrees.
Step-by-step explanation:
If you add 34 and 101, then subtract 180 from that, it's 55.
