Answer:
$8.91
Step-by-step explanation:
Multiply $4.95 times 0.80 ( convert 80% to a decimal ) and that will equal 3.96 .
Then , since you're marking it up , you're gonna add the 3.96 to 4.95 which will equal $8.91 .

Step-by-step explanation:
1) if r = -4
Substitute r = -4 in 3r - 9
= 3 * (-4) - 9
= -12 - 9
= -21
2) ( 4 / 7 ) * x = 16

find the point slope asap plsssssss
Answer:
(5,-5)
Step-by-step explanation:
-1-4
------ = (5,-5)
(6-1)
Answer:
Slope intercept form: y = -x + 5
Point slope form: y - 4 = -1 (x - 1)
Step-by-step explanation:
First we need to find slope by using this formula⤵⤵⤵
[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]
(Sorry if it's a bit small btw)
-1 - 4 = -5
6 - 1 = 5
Simplify -5/5 by dividing, and your slope is -1.
Now we plug in one of the points and the slope into the point slope formula⤵⤵⤵
[tex]y - y _{1} = m(x - x _{1})[/tex]
We'll use point (1,4) for this:
y - 4 = -1 (x - 1)
To solve this, start by distributing the -1 among everything inside the parenthesis to get
y - 4 = -x + 1. Next, add 4 on both sides to get
y = - x + 5.

Find the coordinates of point p along the directed line segment AB, from A (-2,-4) to B (6,1), so that the ratio of AP to PB is 3 to 2
Answer:
Step-by-step explanation:
x distance from A to B
6 - (-2) = 8
3/5(8) = 24/5 = 4.8 or 2/5(8) = 16/5 = 3.2
-2 + 4.8 = 2.8 6 - 3.2 = 2.8
y distance from A to B
1 - (-4) = 5
3/5(5) = 3 or 2/5(5) = 2
-4 + 3 = -1 1 - 2 = -1
P = (2.8, -1)
The coordinates of point P (rounded to one decimal place) along the directed line segment AB are approximately (2.8, -1).
Given that the line segment has been divide into ratio 3:2 by a point P, we need to find the coordinates of the point P.
To find the coordinates of point P along the directed line segment AB, such that the ratio of AP to PB is 3 to 2, we can use the concept of section formula in coordinate geometry.
Let's assume the coordinates of point P are (x, y). According to the given information, the ratio of AP to PB is 3 to 2. This means that the distance between A and P (AP) is three times the distance between P and B (PB).
The section formula states that if a point P(x, y) divides the line segment joining points A(x₁, y₁) and B(x₂, y₂) in the ratio m:n, then the coordinates of point P can be calculated as:
x = (mx₂ + nx₁) / (m + n)
y = (my₂ + ny₁) / (m + n)
In this case, m = 3 and n = 2.
Coordinates of A: (x₁, y₁) = (-2, -4)
Coordinates of B: (x₂, y₂) = (6, 1)
Ratio m:n = 3:2
Now, let's plug the values into the section formula to find the coordinates of P:
x = (3 · 6 + 2 · (-2)) / (3 + 2)
= (18 - 4) / 5
= 14 / 5
= 2.8
y = (3 · 1 + 2 · (-4)) / (3 + 2)
= (3 - 8) / 5
= -5 / 5
= -1
So, the coordinates of point P is (2.8, -1).

Answer:
1 is parallel to 3. 1 is perpendicular to 2. 2 is perpendicular to 3.
Step-by-step explanation:
The slope of line 1 is 5/3. This is because it is the m term from the equation y=mx+b.
The slope of line 2 is -3/5. You would have to solve the equation in the following format.
[tex]6x+10y-6x=-4-6x[/tex]
[tex]\frac{10y}{10}=\frac{-4-6x}{10}[/tex]
Which simplifies to y=-2/5 - 3/5x, making -3/5 the slope.
The slope of line 3 is 5/3, which can be found by dividing both sides of the equation by 3.
Parallel lines have exactly the same slope. So lines 1 and 3 are parallel.
Perpendicular lines have opposite reciprocal slopes. So lines 1 and 2, and 2 and 3 are both perpendicular.
Linnea’s company’s revenue in 2017 is 36/25 of its revenue in 2016

Linnea’s company’s revenue in 2017 as a percent of its revenue in 2016 is; 1.44%.
Let Linnea’s company’s revenue in 2016 be x.Now, we are told that her revenue in 2017 is 36/25 of her revenue in 2016.
This means the revenue in 2017 = (36/25)xTo express this revenue as a percentage, we will multiply 36/25 by 100%.
⇒ 36/25 × 100%.
⇒ 1.44%

Simplify completely
x² + 4x - 45/x^2+10x+9
and find the restrictions on the variable.
Answer:
(x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.
Step-by-step explanation:
Factor the numerator:
(x+9)(x-5)
Factor the denominator:
(x+1)(x+9)
So you have
(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?
You're left with (x-5)/(x+1)
The only number that is restricted is -1, because that would make the denominator zero, which is a no no
Answer:
Step-by-step explanation:
To avoid ambiguity please write the given expression as
x² + 4x - 45
x² + 4x - 45/(x^2+10x+9) or (better) as ---------------------
x^2+10x+9
Notice that both numerator and denominator have the factor x + 9:
(x + 9)(x - 5)
---------------------
(x + 9)(x + 1)
This allows us to cancel out the (x + 9) factor, resulting in:
x - 5
------- ONLY for x ≠ -1 and x = -9
x + 1
We must exclude these two x-values because otherwise the denominator would be zero, which is not allowed.
