Equation of a Straight Line
1.1 Solve y+2x-5 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y+2x-5 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000
y-intercept = 5/1 = 5.00000
Calculate the X-Intercept :
When y = 0 the value of x is 5/2 Our line therefore "cuts" the x axis at x= 2.50000
x-intercept = 5/2 = 2.50000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 1.000 - 5.000 = -4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -4.000/2.000 = -2.000
Geometric figure: Straight Line
Slope = -4.000/2.000 = -2.000
x-intercept = 5/2 = 2.50000
y-intercept = 5/1 = 5.00000

Answer:
Step-by-step explanation:
2cos²θ - 1 - cosθ = 0
(2cosθ + 1)(cosθ - 1) = 0
cosθ = -1/2, θ = 2π/3, 4π/3
cosθ = 1, θ = 0

Can someone help due in an hour
figure 1 is 130 degrees because a whole line is 180 degrees subtract the 50 boom.
figure 2 is a bit more difficult all together it is 360 y is 30 degrees due to vertical angles and x and z are 150 degrees because 360-60=300 divided by 2 equals 150
figure 3 x is 135 due to vertical angles which makes w and y are 45 because 360-270 equals 90 divide by 2 equals 45
figure 4 is 106 because you add 172 and 82 and then subtract that by 360 there you go. hope this helps you out

Finding the original price given the sale price and percent...
At a sale this week, a sofa is being sold for $234. This is a 28% discount from the original price.
What is the original price
Answer:
$325
Step-by-step explanation
78% is 234
x is 100%
cross multiply
[tex]\frac{234}{72}[/tex] = [tex]\frac{x}{100}[/tex]
234 × 100 = 72x
23400 = 72x
23400÷72 =72x ÷72
325 = x
The value of the original price of the sofa would be $325.
Used the concept of percentage that is,
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.
Given that,
At a sale this week, a sofa is being sold for $234.
And, This is a 28% discount from the original price.
Let us assume that the original price = x
Hence, the given condition is written as,
[tex]x - (28\% \ \text{of } x) = 234[/tex]
Solve for x,
[tex]x - (0.28 x) = 234[/tex]
[tex]0.72x = 234\\[/tex]
Divide both sides by 0.72,
[tex]x = \dfrac{234}{0.72}[/tex]
Therefore, the original price would be,
[tex]x = \$325[/tex]

A. L = (3u-5)m; W = (4u + 3)m
B. L= (bu + 5)m; W = (2-3)m
C. L = (6u - 3)m; W = (2u - 5)m
D. L = (12u - 15)m; W = (u + 1)m
plsss answerre huhu helppp
Answer:
L = (6u + 5)m ; W = (2u-3)m
Step-by-step explanation:
Given;
Area of the rectangular vegetable garden, A = (12u² - 8u - 15)m²
Let the length of the rectangular vegetable garden = L
Let the width of the rectangular vegetable garden = W
A = L x W
Factorize the given area;
= 12u² - 8u - 15
= 12u² -18u + 10u - 15
= 6u(2u - 3) + 5(2u - 3)
= (6u + 5)(2u-3)
Thus, L = (6u + 5)m and W = (2u-3)m
Option B, is the right solution, although it was wrongly typed.

What is the radius of the circle in the xy-plane that
has center (1,5) and contains the point (4,9)?
[tex] \huge \qquad \sf \underline{\boxed{ {☘ \sf Sσlutiσn}}}[/tex]
The distance between the centre and any point satisfying the circle is its radius ~
Hence, the distance between the points is equal to length of radius.
[tex]\qquad \sf \dashrightarrow \: r = \sqrt{(4 - 1) {}^{2} + (9 - 5) {}^{2} } [/tex]
[tex]\qquad \sf \dashrightarrow \: r = \sqrt{(3) {}^{2} + (4) {}^{2} } [/tex]

[tex]\qquad \sf \dashrightarrow \: r = \sqrt{25} [/tex]
[tex]\qquad \sf \dashrightarrow \: r = 5[/tex]
As we know, equation of a circle is :
[tex] \qquad \sf(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]
where,
h = x - coordinate of centre k = y - coordinate of centre r = radius of the circleHence, equation of our required clrcle is :
[tex] \qquad \sf(x -1 ) {}^{2} + (y - 5) {}^{2} = {5}^{2} [/tex]
The radius of the circle that has center (1,5) and contains the point (4,9) is 5 units
How to determine the radius of the circle?The center of the circle is given as:
Center (a,b) = (1,5)
The point on the circle is given as:
Point (x,y) = (4,9)
The radius is calculated using the following distance equation
[tex]r = \sqrt{(x - a)^2 + (y - b)^2}[/tex]
So, we have:
[tex]r = \sqrt{(4 - 1)^2 + (9 - 5)^2}[/tex]

How many 1/4 gram doses can be obtained from a 7 1/2 gram vial of medication?
Answer:
30 gram doses
Step-by-step explanation:
First, turn the fractions into decimals.
1/4 gram to .25 gram
7 1/2 gram to 7.5 gram
Then, divide 7.5 total grams by the .25 grams for each dose.
7.5/.25 = 30
Therefore, you can obtain 30 1/4 gram doses from a 7 1/2 gram vial of medication.
Given:
Weight of the vial = [tex]7\frac{1}{2}[/tex] grams
Weight of one dose = [tex]\frac{1}{4}[/tex] gram
To Find:
Number of doses in one vial.
Solution:
Let the number of doses in a vial = n
Therefore, weight of 'n' doses = [tex]n\times \frac{1}{4}[/tex]
= [tex]\frac{n}{4}[/tex] grams
Since, the weight of the n doses is equal to the weight of one vial,
[tex]\frac{n}{4}=7\frac{1}{2}[/tex]
[tex]\frac{n}{4}=\frac{15}{2}[/tex]
[tex]n=\frac{15\times 4}{2}[/tex]
