.6(2k - 3) = 3(4k + 5)
Hellppp pleaseee
Answer:
Step-by-step explanation:
.6(2k-3)=3(4k+5) foil
1.2K-1.8=12k+15 subtract 1.5k from both sides
-1.8=10.8k+15 subtract 15 from both sides
-16.8=10.8k divide by 10.8
k= -1.5

What's the mean median and range of 5, 15, 10, 20,15 10, 15
Answer:
Mean = 12.85714
Median = 15
Range = 15
Step-by-step explanation:
Mean:
5 + 15 + 10 + 20 + 15 + 10 + 15 = 90
90 / 7 = 12.85714
Median:
5, 10, 10, 15, 15, 15, 20
Median = 15
Range:
20 - 5 = 15
Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of the given equation. (4,-3); y=-5x+8
Answer:
Step-by-step explanation:
The slope of the line is m = -5
4 is your x1
-3 is your y1
Plug into the equation y - y1 = m(x - x1)
y + 3 = -5(x - 4)
y + 3 = -5x + 20
-3 -3
y = -5x + 17
Type the correct answer in each box. Use numerals instead of words. Consider this expression.
What expressions is equivalent to the given expression?
Answer:
-4x. 2. 5+5x.
each of them should be filled in different boxes
The solution of the given equation will be (-4)x² + (-3x) + (- 5).
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
For example 3x² + 6x + 8 = 0 here x has highest term as 3 and coefficient of x² is not zero
Given,
⇒ -4x² - 2x - 5( 1 + x )
⇒ -4x² - 2x - 5 - 5x
⇒ (-4) x² + (-3) x + (- 5).
Hence (-4)x² + (-3x) + (- 5) will be the correct answer for the given expression.

coral invested $500 in an account that earns simple interest at the rate of %5.5 each year. Assuming coral does not invest anymore money it will take how many years for coral to have %720 in her account?
Answer:
The number of years it will take coral to have $720 in her account is 8 years
Step-by-step explanation:
The principal amount coral invested, P = $500
The simple interest rate earned per year, r = 5.5%
The amount in coral account after t years, A = $720
The formula for simple interest is given as follows;
[tex]Simple \ Interest, \ SI = \dfrac{Principal, P \times Rate, r \times Time, t}{100}[/tex]
The formula for amount, A = SI + P
Therefore, we have;
[tex]A = \dfrac{P \times r \times t}{100} + P[/tex]
[tex]720 = \dfrac{500 \times 5.5 \times t}{100} + 500[/tex]
[tex]720 - 500 = \dfrac{500 \times 5.5 \times t}{100}[/tex]
[tex]220 = \dfrac{500 \times 5.5 \times t}{100}[/tex]
22000 = 500 × 5.5 × t
t = 22000/(500 × 5.5) = 8
The number of years, t, it will take coral to have $720 in her account = 8 years.
Write an explicit formula that represents the sequence defined by the following recursive formula
HELP IM TIMED
Answer:
The explicit formula is a[tex]_{n}[/tex] = 5 - 6n
Step-by-step explanation:
The explicit formula of the arithmetic sequence of the recursive formula
a[tex]_{1}[/tex] = first term; a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] + d is a[tex]_{n}[/tex] = a + (n - 1)d, where
a is the first termd is the common difference between each two consecutive termsn is the position of the number∵ The recursive formula is a[tex]_{1}[/tex] = -1 and a[tex]_{n}[/tex] = a[tex]_{n-1}[/tex] - 6
→ Compare it with the formula above
∴ a = -1 ⇒ 1st term
∴ d = -6 ⇒ common difference
→ Substitute them in the form of the explicit formula
∵ a[tex]_{n}[/tex] = -1 + (n - 1)(-6)
∴ a[tex]_{n}[/tex] = -1 + (-6)(n) - (-6)(1)
∴ a[tex]_{n}[/tex] = -1 + -6n - (-6)
∴ a[tex]_{n}[/tex] = -1 - 6n + 6
→ Add the like term
∴ a[tex]_{n}[/tex] = 5 - 6n
∴ The explicit formula is a[tex]_{n}[/tex] = 5 - 6n
An online clothing company sells custom sweatshirts. The company charges $ for shipping plus $ for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Complete question :
An online clothing company sells custom sweatshirts. The company charges $4.99 for shipping plus $7.50 for each sweatshirt. Write a linear function rule that models the total cost y (in dollars) for any number of sweatshirts x.
Answer:
y = 7.50x + 4.99
Step-by-step explanation:
Given that :
Shipping fee = 4.99
Cost per shirt = 7.50
Writing the relation in the form of a linear equation :
General form of a linear function :
y = mx + c
Where m = slope ; c = intercept
The total cost of ordering x sweatshirts :
y = (cost per sweatshirt * number ordered) + shipping fee
y = 7.50x + 4.99
Answer:
the answer is $7.99

Answer: I believe it's / option 3: 6 gallons of white paint.
So like tell me the answer I think it’s like either 3 or 6a^9 but I’m not sure
I'm not sure what you mean by 3 or 6a^9, since there are only variables in the photo, but we can try breaking it down.
Let's start with the bottom,
a^2 * a^3 would be a^5 because for exponents you add the exponents of what's multiplied (product rule)
Then using the quotient rule, where you subtract the exponents, a^5/a^5 = a^(5-5)
And anything to the 0th power is 1, so your answer should be 1
Hope that helps!
