Answer:
y = - [tex]\frac{3}{2}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (2, 0) ← 2 points on the line
m = [tex]\frac{0-3}{2-0}[/tex] = - [tex]\frac{3}{2}[/tex]
The line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - [tex]\frac{3}{2}[/tex] x + 3 ← equation of line

In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°. Find the area of ΔIJK, to the nearest square centimeter.
Answer:
11699 square centimeters
Step-by-step explanation:
In ΔIJK, j = 800 cm, k = 240 cm and ∠I=173°. Find the area of ΔIJK, to the nearest square centimeter.
When given two sides of a triangle and an angle, the area of the triangle is calculated as:
1/2jksintheta
theta = 173°
Hence:
Area of triangle =
1/2 × 800 × 240 × sin 173
= 11699.456967 square centimeters
Approximately = 11699 square centimeters
I need help what would this be????
Answer:
first we fisson in three regtangles. and we gain 6 cm to 3cm regtangles. they have the same width and length.
and we find their area. we multiplay 6cm and 3cm. the result is 18 cm square. and they have the same area.
lastly we find the value of the picture by find the sum of three regtangels.18cm square+18cm square+18cm square=
54cm square. fainally the answer is 54cm square.

Answer:
y = 2x - 22
Step-by-step explanation:
y = 2x + 1
Parallel slope: 2
(7, -8)
y - y1 = m(x - x1)
y + 8 = 2(x - 7)
y + 8 = 2x - 14
y = 2x - 22
Answer:
Solution given:
equation of line 1 is:
y=2x+1
2x-y+1=0.......[1]
slope of line 1 is
m1=[tex] \frac{ -coefficient \:of\: x }{coefficient\: of \:y} [/tex]
[tex] \frac{ - 2}{ - 1} = 2[/tex]
Since the lines are parallel than slope of another line m2=m1=2
It passes through (x1,y1)=(7,-8)
equation of a line is:
(y-y1)=m2(x-x1)(y+8)=2(x-7)y+8=2x-142x-y=8+142x-y=22[tex] \frac{2x}{22} - \frac{y}{22} = 1[/tex][tex] \frac{x}{11} - \frac{y}{22} = 1[/tex]is a required equation of a line in slope intercept form.

The difference between two numbers is 308328.If the smaller number is
6524, what is the larger number?
-(2) maths
Answer:
Let get small number is x and large number is y.
The difference between two numbers is 308328.
ie. y- x = 308328.
If the smaller number is
6524.
So, x= 6524.
Hence,
y - x = 308328
y- 6524 = 308328
y = 308328 + 6524
y = 314852
