Solve 9x + 3y = 15 for y.
A. y=-3x + 15
B. y = 9x + 15
C. y = -9x + 5
D. y=-3x + 5
Answer: D) y = -3x + 5
Step-by-step explanation:
Move x.
3y = -9x + 15
Divide by 3.
y = -3x + 5
Hope it helps :) and let me know if you want me to elaborate.
Answer:
D. y = -3x + 5
Step-by-step explanation:
Subtract 9x from both sides
3y = 15 - 9x
y = 15/3 - 9x/3
y = 5 - 3x
y = -3x + 5

The ordered pair (6, 4) is a solution of the linear equation 2x + ky = 8. What is the value of k?
-8
B
-1
What is the Answer
Answer:
k = -1
Step-by-step explanation:
Plug the known values into the linear equation:
[tex]2x + ky = 8\\2(6) + k(4) = 8\\12 + 4k = 8\\[/tex]
Subtract 12 from both sides to isolate 4k:
[tex]12 + 4k - 12 = 8 - 12\\4k = -4\\[/tex]
Divide both sides by 4:
[tex]\frac{4k}{4} = \frac{-4}{4}[/tex]
k = -1

find the value of f(2) in f(x) = 3x ^4– x^ + 5x – 7
Step-by-step explanation:
f(2) = 3x^4 - x + 5x + 7
f(2) = 3(2)^4 - 2 + 5(2) + 7
f(2) = 3(16) - 2 + 10 + 7
f(2) = 48 + 15
f(2) = 63

Justice needs 24 feet of fencing to surround his garden. The fencing is priced at $0.25 per inch how much will it cost justice to fence in his garden?
Answer:
66 dollars
Step-by-step explanation:
Justice needs $72 to fence in his garden.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Justice needs 24 feet of fencing to surround his garden.
The fencing is priced at $0.25 per inch.
Since, 1 foot = 12 inch
Hence, 24 feet = 24 x 12 inch = 288 inch.
Cost of the fencing in one inch = $0.25
So, Cost of the fencing in 288 inch = 288 x 0.25
= $72
Thus, Justice needs $72 to fence in his garden.

Answer:
Step-by-step explanation:
x = 1 - i sqrt(2) ^ y = 10 + i sqrt(2)
x = 1 + i sqrt(2) ^ y = 10 - i sqrt(2)
Answer:
Step-by-step explanation:
y = 11 - x ----------(I)
y = 2x² - 4x + 6 -----------(II)
Substitute y = 11- x in (II)
11 - x = 2x² - 4x + 6
0 = 2x² - 4x + x + 6 - 11
0 = 2x² - 3x - 5
2x² - 3x - 5 = 0
Sum = -3
Product = -10
Factors = -5 , 2
2x² - 5x + 2x - 5 = 0
x(2x - 5) + (2x - 5) = 0
(2x -5 )(x +1)=0
2x - 5 = 0 ; x + 1 = 0
2x = 5 ; x = -1
x = 5/2
When x = -1 ; y = 11 - (-1) = 11 + 1 = 12
[tex]When x = \dfrac{5}{2} ; y = 11- \dfrac{5}{2}= \dfrac{22}{2}- \dfrac{5}{2}= \dfrac{17}{2}[/tex]
Solution: (-1 , 12) and (5/2 , 17/2)

A negative number is 42 less than it’s square.
Answer:
Let x = the number
A negative number is 42 less than its square ⇒
x = x2 - 42
x2 - x - 42 = 0
(x - 7)(x + 6) = 0
x = 7 or -6
But since it is given that x is negative, the final answer is x = -6.
Make the ratios equal. 9:25 = 36:?
The equivalent ratio of 9:25 is 36:100.
Ratio expresses the degree of proportionality between two or more numbers. It expresses the number of times one number is contained in another number.
In order to make the ratios equal, the relationship that exists between 9 and 36 has to be determined. 36 is a multiple of 9. It is 9 multiplied by 4. So, in order to make the ratios equal, multiply, 25 by 4.

Convert decimals to fractions
Answer:I’m not sure if you had a file if so it’s not there but heres something else
Step-by-step explanation:
Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.
