Answer: y=-5/2x-8
Step-by-step explanation:
The equation of the line that passes through the point (-2,-3) and is parallel to the line 5x+2y=1 is
y = (-5/2)x - 8
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We have,
An equation of the line that passes through the point (-2,-3) and is parallel to the line 5x+2y=14.
The equation of a line can be written as:
y = mx + c _____(1)
The line 5x + 2y = 14 can be written in the form y = mx + c.
5x + 2y = 14
2y = -5x + 14
y = -5/2x + 7
m = -5/2 ____(2)
The equation of the line passes through the point (-2, -3) so,
From (1) and (2) we get,
y = mx + c
-3 = -5/2 x -2 + c
-3 = 5 + c
c = -3 - 5
c = -8 ____(3)
Now,
From (1) , (2), and (3) we get,
The equation of the line is
y = (-5/2)x - 8
Thus,
The equation of the line that passes through the point (-2,-3) and is parallel to the line 5x+2y=1 is
y = (-5/2)x - 8

which ordered pair is a solution of the equation: 2y=7x-3
only 2,4
only 3,9
both 2,4 and 3,9
neither
Answer:
It is only 3,9.
Step-by-step explanation:
You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:
2(9) = 7(3)-3
18= 18
The answer is (3,9).

How to do this question plz answer
Step-by-step explanation:
a) m∠AOB = 360°/8 = 45°
Internal angle is 360°, divided by 8 sides of octagon
b) m∠ABC = 2m∠ABO
m∠ABO = m∠BAO = 1/2(180° - 45) = 1.2(135°)
m∠ABC = 2*1/2(135°) = 135°
Answer:
a) 45
b)135
Step-by-step explanation:
[tex]In\ order\ to\ find\ the\ sum\ of\ all\ the\ interior\ angles\ of\ a\ polygon\ with\ sides\ n,\\S=180(n-2)\\Here,\\As\ the\ figure\ is\ a\ regular\ octagon\ ,\\The\ sum\ of\ all\ of\ its\ angles\ = 180(8-2)\\=180*6=1080\\Hence,\\Given\ that\ it\ is\ regular\ or\ that\ all\ of\ its\ angles\ are\ equal\ in\ measure.\\Hence,\\b) Angle\ ABC=1080/8\\=135\\As\ it\ is\ regular\ , the\ diagonals\ passing\ through\ the\ center\ bisects\ the\ respective\ angles.[/tex]Hence,

Simone paid $12 for an initial year's subscription to a magazine. The renewal rate is $7 per year. This situation can be represented by the equation y = 7x + 12, where x represents the number of years the subscription is renewed and y represents the total cost, in dollars.
Answer:
Step-by-step explanation:
Step one:
Simone paid $12 initial subscription
The rate renewable = $7 per year
let the number of years be x
and the total amount be y
the linear function/expression for the total amount is represented using the equation of line
i.e y=mx+c
where
m= gradient = $7
x= independent variable
c= constant, $12
this is also given as
y=7x+12
Step two:
let's assume the plan is for 3 years, that is x=3
then
y=7(3)+12
y=21+12
y=33
$33
For any number of years, just put x=the number of years and solve

What equation is being represented by this line?
Answer:
The equation that represented by the line is y = -x + 2
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given figure
∵ The line passes through points (2, 0) and (0, 2)
∴ x1 = 2 and y1 = 0
∴ x2 = 0 and y2 = 2
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{2-0}{0-2}=\frac{2}{-2}=-1[/tex]
∴ m = -1
→ Substitute it in the form of the equation above
∵ y = -1(x) + b
∴ y = -x + b
∵ b is value y at x = 0
∵ At x = 0, y = 2
∴ b = 2
→ Substitute it in the equation above
∴ y = -x + 2
∴ The equation that represented by the line is y = -x + 2

Use the elimination method to solve the system of equations. Choose the correct ordered pair
-x+5y=-4
4x+3y=16
Will give brainiest.
Answer:
x = 4 and y = 0
Step-by-step explanation:
Using the elimination method:
4(-x + 5y=-4) --> -4x + 20y = -16.
Now we add -4x + 20y = 016 and 4x + 3y = 16. This gives us 23y = 0 or just y =0.
Now we can find x by plugging in y.
-4x + 0 = -16.
Divide by -4 on both sides -> x = 4.
If you want to double check you can plug your values into -4x + 20y = -16.
-4(4) +20(0) = -16.
Mrs. Conley asks her class what kind of party they want to have to celebrate their excellent behavior. Out of all the students in the class,
5
55 want an ice cream party,
7 77 want a movie party,
10 want a costume party, and the rest are undecided.
If 20% percent want an ice cream party, how many students are in the class?
Step-by-step explanation:
let 'x' represent the total number of students in the class
5 = 20% of x
0.20x = 5 divide both sides by 0.20
x = 25 students
there are 25 students in the class.
