Answer:
y=-4x-4
Step-by-step explanation:
m=-4
point(-2,4)
y-4 = -4 (x- (-2) )
y-4 = -4 (x+2)
y-4 = -4x -8
y = -4x -4
Step-by-step explanation:
we are going to use quadratic equation for this particular question . so now we are going to change the signs i.e from negative to positive or from positive to negative(-2 will turns to +2) nd +4 will turns to-4)
therefore, (x+2)(x-4) then we na expand the bracket x(x-4)+2(x-4)
x square -4x+2x-8
therefore the equation is nothing but x square-2x-8

4n2-17n+4
What is the answer
Answer:
(4n − 1)(n − 4)
Explanation:
Factor 4n² − 17n + 4
4n² − 17n + 4
= (4n − 1)(n − 4)
Answer:
(4n − 1)(n − 4)
The factors of the expression [tex]4n^2-17n+4[/tex] are
Mathematically, an expression is a combination of numbers, variables, operations, and functions that are combined according to specific rules to represent a mathematical computation or relationship. It can be thought of as a mathematical phrase or formula.
To factorize the quadratic expression [tex]4n^2 - 17n + 4[/tex], we need to find two binomial factors that, when multiplied, result in the given expression.
The factored form will have the following structure:
(An + B)(Cn + D)
To find the values of A, B, C, and D, we can use various methods such as factoring by grouping, quadratic formula, or completing the square. In this case, we will use the factoring by grouping method.
Step 1: Multiply the coefficient of the leading term (4) by the constant term (4). The result is 16.
Step 2: We need to find two numbers that multiply to give 16 and add up to the coefficient of the linear term (-17). After considering the possible pairs of numbers, we find that -16 and -1 meet these criteria.
Step 3: Rewrite the middle term (-17n) using -16n - n:
= [tex]4n^2 - 16n - n + 4[/tex]
Step 4: Group the terms and factors by grouping:
= [tex](4n^2 - 16n) - (n - 4)[/tex]
= 4n(n - 4) - 1(n - 4)
Step 5: Factor out the common binomial factor:
(n - 4)(4n - 1)
Therefore, the factored form of the quadratic expression [tex]4n^2 - 17n + 4[/tex] is (n - 4)(4n - 1).

Tricia has $37.25 in her account. Which shows the amount she will have left after she writes a check for $23.99?
A. $12.36
B. $12.74
C. $13.26
D. $13.74
The amount she will have left after writing a check for $23.99 is $13.26. The correct answer would be an option (C).
What is the Subtraction operation?Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
Tricia has $37.25 in her account, if she writes a check for $23.99, to find the amount left after that we need to subtract the check amount from her initial amount.
⇒ initial amount - check amount
⇒ $37.25 - $23.99
Apply the subtraction operations, and we get
⇒ $13.26
Therefore, the amount she will have left after writing a check for $23.99 is $13.26.

Solve for r.
1/3r+1=−2/3r−2
Answer:
-3
Step-by-step explanation:
Answer:
[tex]r=-3[/tex]
Step-by-step explanation:
We have the equation:
[tex]\displaystyle \frac{1}{3}r+1=-\frac{2}{3}r-2[/tex]
And we would like to solve for r.
First, we can multiply both sides by the denominator 3. This will remove the fractions. So:
[tex]\displaystyle 3(\frac{1}{3}r+1)=3(-\frac{2}{3}r-2)[/tex]
Distribute:
[tex]\displaystyle r+3=-2r-6[/tex]
Now, we can add 2r to both sides:
[tex]3r+3=-6[/tex]
And we can also subtract 3 from both sides:
[tex]3r=-9[/tex]
Finally, we can divide both sides by 3 to get:
[tex]r=-3[/tex]

Is the equation 2x + 5 = 1 true, false, or open? Explain.
Answer:
open
Step-by-step explanation:
beacause
2x+5=1
2x=1-5
2x=-4
x=-4/2
x-2 so its open
An open statement is a statement that has an unknown variable
[tex]2x + 5 = 1[/tex] is an open statement
The equation is given as:
[tex]2x + 5 = 1[/tex]
From the equation, we have the following observations.
2, 5 and 1 are constants
x is a variable
Because the equation has a variable (i.e. x), then it is an open statement
Hence, [tex]2x + 5 = 1[/tex] is an open statement

Paul and Kristen have planned a long hike. They will both travel the same route and will not stop. Paul starts two hours before Kristen. He walks three miles per hour and does not slow down or speed up. If Kristen walks four miles per hour, and does not slow down or walk faster, how many miles must she walk to catch up with Paul?
Answer:
Kristen should walk 12 miles to catch up with Paul
Step-by-step explanation:
Paul = 2hrs earlier
= walks at 3 miles per hour
= 3miles x 2 hrs = 6 miles
covers 6 miles at the time Kristen starts
Kristen = 4 miles per hour
Paul has a lead of 6 miles.
if Kristen walks another hour of 4 miles she would have covered 8 miles and Paul would have covered 9 miles and if Kristen were to cover one more hour,
Kristen would be at 12 and so would Paul.
Kristen should walk 12 miles to catch up with Paul

Kevin wants to plant grass in his backyard. His backyard is in the shape of a rectangle. Its length is 28 feet and its width is 25 feet. Suppose each pack of seed
covers 14 square feet. How many packs of seed will he need to cover the backyard?
Answer:
50 packs.
Step-by-step explanation:
Given the following data;
Length = 28 feet
Width = 25 feet
Pack of seeds = 14 ft²
Since Kevin's backyard is a rectangle, we would find its area.
Area of rectangle = length * width
Substituting into the equation, we have;
Area of rectangle = 28 * 25
Area of rectangle = 700 ft²
Now to find the amount of pack of seeds required to cover the backyard.
Amount of pack of seeds = 700/14
Amount of pack of seeds = 50 packs.
