The correct option is (d).
d) (2,-6) & (4,-16)
Now, To find the correct option that is equivalent to this equation, we can begin by narrowing down the given options.
Since, The slope contains a negative number, that's mean the second point must have a lower y value than the first x value.
Hence, By using this criteria, we can eliminate the first and the third option.
Now, we can check the second and fourth option as;
We can test using by putting in values.
Let's plug in the point values to check whether they work:
Hence, For option 2:
y = -5x + 4
-24 = -5(4) + 4
-24 = -20 + 4
-24 ≠ -16
And, For option 4:
y = -5x + 4
-16 = -5(4) + 4
-16 = -20 + 4
-16 = -16
Therefore, The correct option is option (d).
The complete question is this;
Which line has an equation of y= -5x+4 in slope intercept form?
A line passing through the points -
a) (1,9) & (3,19)
b) (2,-14) & (4,-24)
c) (1,1) & (3,11)
d) (2,-6) & (4,-16)

Kathy loves the K-Pop group BTS. She wants to buy their World Tour DVD for $27.80.
a) The tax for the album is 0.15 of the cost. How much is tax?
b) if Kathy has $35, how much will change will she get back after buying the album and paying tax
Tax levied is $4.17 if the price of album is $27.80.
Kathy will get $3.03 after buying the album and paying the tax.
What is tax?A tax is a mandatory financial charge or other sort of levy that is placed on a taxpayer by a governmental entity in order to pay for public services and other expenses.
The total amount is calculated by adding the tax on the cost of product or service.
How are Total Amount and Tax related?The pre-tax price of an item must first be multiplied by the sales tax percentage once it has been translated to a decimal form in order to determine the amount of sales tax that will apply to the purchase. To determine the item's Total Amount, the sales tax must be computed and then added to the pre-tax price.
a) Given data: Tax%=0.15 of cost of album
Selling Price=$27.80.
Tax=Tax%×Selling Price
=0.15×27.80
=$4.17
b) Given data: Amount given by Kathy = $35
Tax=$4.17
Total Amount = Selling Price + Tax
=$4.17+$29.80
=$31.97
Amount left can be calculated by subtracting the amount given by Kathy from the Total Amount.
Amount=$35-$31.97
=$31.97

What does it mean to round off?Rounding off means simplifying a number by keeping its overall value but moving it closer to the next number. It is used for whole numbers and decimals with tens, hundreds, thousands, and so on.
What precisely seems to be the rounding off rule?If the digit in the smallest spot is less than 5, it is left alone. Rounding down occurs when any number of digits then after the number become zero. If the digit inside the smallest place is larger than or equal to 5, it is multiplied by +1.

Simplify each number. 4¹/₂
The simplified form of number is 2
To find the simplified form of the number, we will find the number whose square is equal to 4. As per the known fact, only 2 is the number whose square is 4.
Firstly rewriting the number -
Number = [tex]4^{1/2}[/tex]
Now, rewriting the number with base as 2 and exponent also as 2, as stated in theory above -
Number = [tex]2^{2(1/2)}[/tex]
Cancelling 2 from the exponent as it is present in both numerator and denominator. Rewriting the number with 2 as base and 1 as exponent to find the simplified form of the number.
Number = 2
Hence, the simplified number is 2

determine algebraically, whether the following function is ever, odd, or neither. g(x)= x^ square root of 1+x
The function g(x)= x^ square root of 1+x is neither an even function nor an odd function
How to determine the function type?The function is given as
g(x)= x^ square root of 1+x
Rewrite the above function equation properly
So, we have
g(x) = x^(√x+1)
Calculate g(-x)
So, we have
g(-x) = -x^(√-x+1)
Evaluate
g(-x) = -x^(√-x+1)
Calculate -g(x)
So, we have
-g(x) = -x^(√x+1)
In the above computations;
g(x) does not equal g(-x) and -g(x)
Hence, the function g(x)= x^ square root of 1+x is neither an even function nor an odd function

Answer:
7. 17
8. -7
9. 64/3 or 21 1/3
Step-by-step explanation:
7. 3x-4 and the value of x is 7. Plug 7 into the x values in the expression that is given.
3x-4 --> 3(7) - 4
When simplified, 3(7) - 4 becomes 21-4 which is 17.
8. -5x+8 and the value of x is 3. Same as before, but this time you'll plug 3 into the x values in the given expression.
-5x+8 --> -5(3) + 8
When simplified, -5(3) + 8 becomes -15+8 which is -7.
9. 10x+18 and the value of x is 1/3. Plug in 1/3 into the x values in the expression.
10x+18 --> 10(1/3)+18
When simplified, 10(1/3)+18 becomes 10/3+18. To solve this, turn 18 in a fraction over 3. 3x18=54 and that gives you the numerator. 10/3+54/3= 64/3. If you wanted it in a mixed fraction, it would be 21 1/3.

The variable w is as follows:
[tex]w = \frac{393+\sqrt{189221} }{12}[/tex][tex]w = \frac{393-\sqrt{189221} }{12}[/tex]How to find the variable in an equation?We have to find the variable w in the equation.
-61 = 8 - 1 / 3(12w + 42) - w
subtract 8 from both sides of the equation
-61 = 8 - 1 / 3(12w + 42) - w
-61 - 8 = 8 - 8 - 1 / 3(12w + 42) - w
-69 = - 1 / 3(12w + 42) - w
69 = 1 / 3(12w + 42) + w
Therefore,
[tex]\frac{1}{3(12w+42)}+w[/tex] = 69
[tex]\frac{1+3w(12w+42)}{3(12w+42)}[/tex] = 69
[tex]\frac{1 + 36w^{2} +126w}{3(12w+42)}[/tex] = 69
cross multiply
1 + 36w² + 126w = 2484w + 8694
36w² + 126w - 2484w - 8694 + 1 = 0
36w² - 2358w - 8693 = 0
using,

let x - 4z = 8 be equation (1), 12x - y - 6z = 8 be equation (2) and 42x + 3y - 2z = 8 be equation (3)

y = 42z + 88

Using greatest common factor (GCF), Mr. Raymond should put 6 students in each group. If that happens, he will have 3 groups of 6th graders and 4 groups of 7th graders.
The greatest common factor (GCF) of a set of numbers is defined as the largest common positive integer that divides each number into equal parts with zero remainder.
If Mr. Raymond has 18 6th graders students and 24 7th grader students he wants to put in equal groups wherein each group will have students of only one grade level, find the GCF of 18 and 24 to find how many students he will put in each group.
18 : 1, 2, 3, 6, 9, 18
24 : 1, 2, 3, 4, 6, 8, 12, 24
GCF = 6
Hence, he should put 6 students in each group.
