Answer:
6x-3=9
Step-by-step explanation:
i dont really get what it means by set up an equation but heres what i know-
36 is the perimeter so divide it by 4 to get the length of each side-
36/4=9
now you know that each side is 9, so 6x-3=9
when you solve that, x=2
write a fraction whose numerator and denominator add up to 9

ax +3= 6
Solve for x.
Answer:
Step-by-step explanation:
Let's solve for a.
ax+3=6
Step 1: Add -3 to both sides.
ax+3+−3=6+−3
ax=3
Step 2: Divide both sides by x.
ax /x = 3 /x
a= 3 /x
Answer:
a= 3 /x
Answer:
ax = 3
Step-by-step explanation:
ax + 3 = 6
Subtract 3 from both sides of the equation
ax = 3

Find the equation of the line by given two points (-5, -2) and (1, 5). Slope
Intercept Form: y = mx +b, m is a slope and b is y value of the y-intercept Slope
formula: m = (y2 - y1)/(x2 - x1)
Answer:
The equation of the line is 6y = 7x + 23
Step-by-step explanation:
We begin by calculating the slope of the line;
mathematically, the slope is given by;
m = (y2-y1)/(x2-x1)
That would be;
m= (5-(-2))/(1-(-5))
m = 7/6
So the equation becomes;
y = 7/6x + b
We below need to get the value of the y-intercept b
We get this by making a substitution for any of the two points
Let’s say we make the substitution for (-5,-2) in which case y = -2 and x = -5
Thus, we have
-2 = 7/6(-5) + b
-2 = -35/6 + b
b = -2 + 35/6
b = (-12+ 35)/6 = 23/6
So we have;
y = 7/6x + 23/6
let’s multiply through by 6
6y = 7x + 23
what ordered pair would describe each intersection?
y=8-X and y=5X-40
Answer:
(8, 0 )
Step-by-step explanation:
Given the 2 equations
y = 8 - x → (1)
y = 5x - 40 → (2)
Substitute y = 5x - 40 into (1)
5x - 40 = 8 - x ( add x to both sides )
6x - 40 = 8 ( add 8 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (1)
y = 8 - 8 = 0
Solution is (8, 0 )

Lisa takes a taxi uptown, and the fare is $12.78. She wants to give the driver a 10% tip.
How much would the tip be?
O $1.28
$5.94
$14:06
$18.72
Answer:14:06
Step-by-step explanation:
Because because 10 percent of 12.78 is 1.28 then 1.28 + 12.78 = 14.06 so 14.06 is your answer

The vertices of a figure are FC -9,- 9),G-3, -6),H(-3,-9). Find the coordinates of the image after a dilation with a scale factor of 2 3 and then a translation 6 units up.
Transformation involves changing the size and position of a figure.
The new coordinates of the figure is:
[tex]\mathbf{F" = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,0)}[/tex]
The coordinates are given as:
[tex]\mathbf{F = (-9,-9)}[/tex]
[tex]\mathbf{G = (3,-6)}[/tex]
[tex]\mathbf{H = (-3,-9)}[/tex]
When the figure is dilated by 2/3, the new coordinates are:'
[tex]\mathbf{F' =\frac 23 \times (-9,-9) = (-6,-6)}[/tex]
[tex]\mathbf{G' =\frac 23 \times (3,-6) = (2,-4)}[/tex]
[tex]\mathbf{H' =\frac 23 \times (-3,-9) = (-2,-6)}[/tex]
When the figure is further translated up by 6 units, the new coordinates are:
[tex]\mathbf{F" = (-6,-6 + 6) = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,-4 + 6) = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,-6 + 6) = (-2,0)}[/tex]
Hence, the new coordinates are:
[tex]\mathbf{F" = (-6,0)}[/tex]
[tex]\mathbf{G" = (2,2)}[/tex]
[tex]\mathbf{H" = (-2,0)}[/tex]

Is an imaginary "line" from the Earth to the Moon a line, a ray, or a segment? and WHY?
Answer:
Segment
Step-by-step explanation:
It is a segment because it has two endpoints (the Earth and Moon). If it was a ray, it would go on forever in one direction. It doesn't, so the imaginary line is a segment.
The first image is a segment, the second is a ray.
Hope this helps. :)
Answer:
Segment
Step-by-step explanation:
A ray goes on forever a segment has end points

derive the equation of a parabola with a focus of (-7,5) and a directrix of y=-11
I need help with this question
Answer:
The equation of the parabola is;
(y + 11)^2/120 = (x + 7)^2 + (y-5)^2
Step-by-step explanation:
Here, we are given the focus (-7,5) and the directix y = -11
We proceed to find the equation of the parabola
That would be in the form;
(y- mx - b)^2 /m^2 + 1 = (x- h)^2 + (y-k)^2
Let’s write the directix in the form y = mx + b
This shows that m = 0 and b = -11
Also h = -7 and k = 5
So let’s substitute;
(y + 11)^2 /(-11^2 + 1) = (x+7)^2 + (y-5)^2
= (y + 11)^2/120 = (x + 7)^2 + (y-5)^2
Answer:
★ The answer is down BELOW
EQUATION : (y + 11)^2/120 = (x + 7)^2 + (y-5)^2

How do you know if a set of information shows a proportional relationship? Select ALL that apply.
Answer:
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Surveyors wished to know the distance across a lake between A and B. They measured the distance from B to C as 100 m and the angle from C to A to be 55°. Knowing that the angle between CB and BA was 90°, they used trig to solve for the distance. Show how it was done
Answer:
AB ≈ 70mStep-by-step explanation:
Check the attachment for the diagram.
You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;
tan 35° = opposite/adjacent
tan 35° = AB/BC
tan 35° = AB/100
AB = 100tan35°
AB = 100 * 0.7002
AB = 70.02m
Hence the distance across a lake between A and B is approximately 70m
