Answer:
The answer is
[tex]y = - 5x - 2[/tex]
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]
❃Incase you also forgot, The is what the slope formula is ☟
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 2 - 3}{0 - ( - 1)} = \frac{ - 5}{ \: \: \: 1} = - 5[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ 3 = - 5( - 1) + b \\ 3 = 5 + b \\ \frac{ - 5 = - 5 \ \ \: \: \: \: \: \: }{ - 2 = b}[/tex]
➌Third: Plug in.
[tex]y = - 5x - 2[/tex]

A circle above has a radius of 6 cm. What is the area of the circle?
Use = 3.14.
Answer:
113.04
Step-by-step explanation:
formula for area is
pi times radius times radius
if the radius is 6,
do 6 times 6=36
36 times 3.14=113.04
the property name for 20+0=20
Answer: Identity Property of Addition
Step-by-step explanation: The identity property holds true for addition.
The statement 20 + 0 = 20 represents the identity property of addition.
The identity property of addition says we add 0
to any number, the sum is equal to the original number.
In general terms, we can write the identity property of addition
as a + 0 = a where a is a variable that represents any number.
Which equation represents a line that passes through the point ( 6 , − 3 ) and is parallel to the graph of y = 3 x + 1 ?
Answer:
y + 3= 3(x - 6) ← point-slope form
y = 3x - 21 ← slope-intercept form
3x - y = 21 ← standard form
Step-by-step explanation:
The point-slope form of the equation of line it's y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = 3x + 1 ⇒ m₁ = 3 ⇒ m₂ = 3
(6, -3) ⇒ x₁ = 6, y₁ = -3
point-slope form:
y - (-3) = 3(x - 6)
y + 3 = 3(x - 6)
y + 3 = 3x - 18 {subtact 3 from both sides}
y = 3x - 21 ← slope-intercept form
-3x + y = -21 {multiply both sides by (-1)}
3x - y = 21 ← standard form

Students in elementary school attends school five days each week after three weeks of attendance each student has attended school for a total of 6300 minutes for how many hours each day does each student attend the school
Answer:
Step-by-step explanation:
first lets meake the minutes into hours by dividing our minutes into hours
6300 / 60 = 105
so in total they go 105 hours in 15 days (5 days for 3 weeks is 15 days)
to find how many hours in each day lets divide our hours into the 5 days
105 / 15 = 7 hours a day

According to Foolproof, by not negotiating the price of your first car purchase, you have a $1,000 "bad" money burn. How long would it take you to earn back the thousand dollars you just threw away if you take home $10.00 per hour? State in terms of how many hours it would take to earn back that money, and explain how you calculated this answer.
Answer:
Time required to save 1000$ is 100 hours
Step-by-step explanation:
Money wasted = 1000$
savings = 10.00$ per hour
using unitary method
if i am saving 10.00 $ per hour then let in t hours i save 1000$
⇒ 10.00 x t = 1000
dividing above equation by 10 we get,
⇒ t = 100 hours
Therefore, Time required to save 1000$ is 100 hours

Use the diagram below to answer
the following question(s).
In the diagram below, MQ = 30, MN = 5, MN = NO, and OP = PQ.
MN
P
Find the length of PQ.
5
10
15
25
Answer:
Step-by-step explanation:
The total distance is 30.
According to MQ = 30 .
And the first distance is
MN which is 5
MN = 5
and NO is equal to MN
MN = NO
giving us MN + NO = 10 or 5 + 5 =10
so if we need 30 and have 2 points that equal to 10
we need 20 more to equal 30
leaving OP = PQ or 10 = 10
10+10+5+5= 30
MN + NO + OP + PQ = MQ

Answer:
x = 20 degrees
Step-by-step explanation:
From the diagram shown, we are to find the value of
Since the adjacent side of the parallelogram on top are equal, hence their opposite angles are also equal
The third angle in the triangle below will be 180 - 60 = 120
Sum of angle in the triangle is 180 degrees, hence;
x + 2x + 120 = 180
3x = 180-120
3x = 60
x = 60/3
x = 20 degrees
Hence the value of x in the diagram is 20 degrees
