The equation of line that passes through point (2,-1) and has a slope of -3 is [tex]\mathbf{y=-3x+5}[/tex]
Option A is correct.
Step-by-step explanation:
We need to write equation of line that passes through point (2,-1) and has a slope of -3
The equation is written in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We are given slope: m = -3
We need to find y-intercept (b)
Using the point (2,-1) and slope m=-3, we can find y-intercept
[tex]y=mx+b\\-1=-3(2)+b\\-1=-6+b\\b=-1+6\\b=5[/tex]
So, we get y-intercept b = 5
Now, the required equation having slope m =-3 and y-intercept b = 5 will be:
[tex]y=mx+b\\y=-3x+5[/tex]
So, the equation of line that passes through point (2,-1) and has a slope of -3 is [tex]\mathbf{y=-3x+5}[/tex]
Option A is correct.

3n + 7 - 11n - 31 = 160
Answers
Answer:
n = -23
Step-by-step explanation:
3n + 7 - 11n - 31 = 160
Step 1: Combine like terms
-8n - 24 = 160
Step 2: Simplify
-8n = 184
n = -23
Answer:
= −23
Step-by-step explanation:
Subtract the numbers
3 + 7 - 11-31 = 160
3-24 - 11 = 160
Combine like terms
3 - 24-11 = 160
-8 - 24 = 160
Add 24 to both sides of the equation
-8 - 24 = 160
-8 - 24 + 24 = 160 + 24
Simplify
Add the numbers
Add the numbers
--> -8 = 184
Divide both sides of the equation by the same term
-8 = 184
-8/-8 = 184/-8
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
--> = -23
Two submarines began dives in the same vertical position to meet at a designated point.
If one submarine was on a course approximated by the equation x + 4y = -14 and
the other was on a course approximated by the equation x + 3y = -8, at what location would they meet?
Answers
Answer:
(10, -6)
Step-by-step explanation:
The solution of the system of the equations given would be the location that they would both meet.
Let's solve:
x + 4y = -14 ----› Eqn. 1
x + 3y = -8 -----› Eqn. 2
Subtract Eqn. 2 from Eqn. 1
y = -6
Substitute y = -6 into Eqn. 1.
x + 4y = -14 ----› Eqn. 1
x + 4(-6) = -14
x - 24 = -14
x = -14 + 24 (addition property of equality)
x = 10.
The answer is: (10, -6)
The volume and base area of a rectangular cargo container is 720 cubic
meters and 120 square meters. Find the height of the container? *
A)86,400m3
B)400m3
C)4m
D)6m
Answers
Answer:
D, 6m
Step-by-step explanation:
Step one:
Given data
The volume and base area of a rectangular cargo container is 720 cubic
= 720m^3
The area of the cargo container is 120 m^2
Required
We want to find the height of the container
Step two
The expression for the volume is given as
Volume= Area* height
so,
720= 120*h
divide both sides by 120
720/120= h
h= 6 m
The height is 6m

Jay played 350 solitaire games he won 154 of those games. What percent of the games did Jay win?
Answers
Answer:
44.044
Step-by-step explanation:
To find the answer we first have to find the value of each percent, to do this we divide 100 by 350, that gets us approximately 0.286. We know that he won 154 of them we then multiply 154 by 0.286 to get the percentage of games he won and we get 44.044.
154/350=0.44
0.44=44%

First, it would be easiest to start by drawing a picture. To do so, draw two simple Isosceles triangles. Then, label their points. One having the points F, U, and N while the other has B, A, and T. Now, since both triangles are congruent, that means that F≅B, U≅A, and N≅T. Because of this knowledge, FN would be congruent to BT. So, you would be able to write that 52 = 14x - 60. By solving that, you would get the answer to x. Moving onto y, you would see that since the triangles are congruent, the interior angles are too. So, you would be able to use angles F and N to find A. By adding them to 180°, the equation would look like: 71° + 36° + (3y + 19)° = 180°. So, you would be able to find the answer to y. Hope this helped!
