Answer:
y=-1/2x+1
Step-by-step explanation:
2x+4y=16
4y=-2x+16
y=-1/2x+4
y=mx+b, m=-1/2, x=4, y=-1
-1=(-1/2)(4)+b
-1=-2+b
1=b
y=-1/2x+1
Can someone help solve this?
Answer:
x = 8
y = 18
Step-by-step explanation:
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!
if 50% is 15 what is 100%
Answer:
30
Step-by-step explanation:
If 50% is 15 then to find 100% you have to multiply 15 by 2
Because 50% is half of 2.
15•2=30
Answer:
30
Step-by-step explanation:
50% half 100 so 15*2 is 30

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?
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)

Jay played 350 solitaire games he won 154 of those games. What percent of the games did Jay win?
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.

All right triangles are isosceles.
Which example proves this statement is false?
Answer:
B
Step-by-step explanation:
It is a 3-4-5 right triangle
The example Option B is False as it is a right triangle with base lengths 3 , 4 and 5
Hence , the example B is not an isosceles triangle
What Is an Isosceles Triangle?
A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.
The three types of Isosceles Triangles are :
Isosceles acute triangleIsosceles right triangleIsosceles obtuse triangleGiven data ,
A)
From the figure Triangle A
In this Triangle , the two sides are of equal length and one side is different
So , the triangle is an isosceles triangle
B)
From the figure Triangle B
In this triangle , all the three sides are different and it is also a right angled triangle with different lengths
So , the triangle is not isosceles
C)
From the figure Triangle C
In this Triangle , the three sides are of equal length , so it is also an isosceles triangle
So , the triangle is an isosceles triangle
D)
From the figure Triangle D
In this Triangle , the two sides are of equal length and one side is different
So , the triangle is an isosceles triangle
Hence , the example B is not an isosceles triangle and is FALSE

3n + 7 - 11n - 31 = 160
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

54.95 / 7.85= 7
Answer:
7
Step-by-step explanation:

or
54.95=7.85x
divide by 7.85 on both sides
7=x
he bought 7 packs

Choose an equivalent ratio. 4:9
A) 27:40
B) 27:18
C) 12:27
D) 16:27
Answer:
The answer is C.
Step-by-step explanation:
The answer is C because both numbers in 4:9 can be multiplied by the same factor (3) to get 12:27, the answer. No other choice works because they require two different number factors, not just one, which means they aren't equivalent ratios to 4:9.

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
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
