Answer:
(-1, -2)
Step-by-step explanation:
-2x + y = 0
y = 2x
5x + 3y = -11
5x + 3(2x) = -11 => 5x + 6x = -11
11x = -11
x = -1
-2(-1) + y= 0
2 + y = 0 => y = -2
Answer:
y=2x and y=mx+b.

Answer:
x=3.11
Step-by-step explanation:
Sin 15 degrees = x/12
multiply 12 on both sides to get rid of the denominator
now you have 12 times the sin of 15 degrees = x
which can also be written as 12 sin 15 = x
put 12 sin 15 into your calculator and you get 3.105828541 or just 3.11 when rounded to the nearest hundreth

An artist mixes 25 ounce of blue paint with 115 ounce of green paint. Using the same ratio, how many ounces of green paint should she mix with 3 ounces of blue paint?
Answer:
Ounces of green paint needed = 13.8
Step-by-step explanation:
Blue paint : green paint = 25 : 115
how many ounces of green paint should she mix with 3 ounces of blue paint?
Let
Ounces of green paint needed = x
Blue paint : green paint = 3 : x
Equate both ratios
25 : 115 = 3 : x
25/115 = 3/x
25 * x = 115 * 3
25x = 345
x = 345/25
x = 13.8 ounces
Ounces of green paint needed = 13.8

Casi drove 135 miles in 3 hours. Use a proportion to find how long it would take her to drive 360 miles at the same speed.
Answer:
8 hours
Step-by-step explanation:
We are given that
Casi traveled distance in 3 hours=135 miles
We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .
Let time taken by Casi to drive 360 miles=x
We know that
Speed=[tex]\frac{Distance}{time}[/tex]
Using proportion
[tex]\frac{a}{b}=\frac{c}{d}[/tex]
[tex]\frac{135}{3}=\frac{36}{x}[/tex]
[tex]x=\frac{360\times 3}{135}[/tex]
[tex]x=8[/tex]
Hence, the time taken by Casi to drive 360 miles=8 hours

The sum of outer angles of a polygon is twice the sum of inner angles. How many sides does it have?
Answer:
3 sides
Step-by-step explanation:
sum of exterior angles for all polygons is 360°
sum of interior angles for a polygon can be found by using the formula:
(n - 2) · 180° where 'n' is the number of sides
'sum of outer angles' = 360
'twice the sum of inner angles' = 2n
360 = 2n
n = 180
a three-sided polygon (triangle) has 180 degrees

what would the angle be! asap answer
Answer:
x = 111°
Step-by-step explanation:
Angles in a triangle add up to 180
180 - (29+82) = 69
Angles on a straight line add up to 180
180 - 69 = 111
Answer:
111°
Step-by-step explanation:
the sum of the outer angles of a triangle is alway 180
so 180-82-29= 69°
180-69= 111°

Answer:
100
Step-by-step explanation:
here we are solving for x
first plug in 100 for the ys in the equation
0.10x + 0.10(100) = 0.18(x + 100)
simplify
0.10x + 10 = 0.18x + 18
get x by itself
-8 = 0.08x
-100 = x
so the reasonable answer here would be 100

1. Write out the law of cosines and find the hypotenuse of triangle with 2 sides lengths equal to three and the included angle measuring 75 degrees.
2. What happens in law of cosines formula if the angle from the above question is changed to 90 degrees.
Answer:
1.) [tex]\sqrt{13.341}[/tex] ≈ 3.652
2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.
Step-by-step explanation:
I think we may have the same class so hopefully this helps:
1.) [tex]a^2 = b^2 + c^2 - 2bccosA[/tex] --> law of cosines formula.
[tex]a^2 = 3^2 + 3^2 - 2(3)(3)cos(75)[/tex] --> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.
[tex]a^2 = 18 - 18cos75[/tex] --> in between steps.
[tex]a^2 = 13.341[/tex] --> more simplifying.
[tex]a(hypotenuse) = \sqrt{13.341} or 3.652[/tex] --> answer
2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.
Good luck! :)
The rectangular pool is 45 feet x 18 feet. The fence needs to be 5 ft away from the edges of the pool or a 5 ft border. How many feet of fencing would you need? The area is 810ft
Answer:
The length of fencing is 146 feet.
Step-by-step explanation:
The length of fencing is equal to the perimeter of the rectangle plus 8 times the width of the border between the edge of the pool and the fence. By Geometry, we find that the perimeter ([tex]p[/tex]), measured in feet, is equal to:
[tex]p = 2\cdot (w+f)+2\cdot (l+f)[/tex] (1)
Where:
[tex]w[/tex] - Width of the pool, measured in feet.
[tex]l[/tex] - Length of the pool, measured in feet.
[tex]f[/tex] - Width of the border, measured in feet.
If we know that [tex]w = 45\,ft[/tex], [tex]l = 18\,ft[/tex] and [tex]f = 5\,ft[/tex], then the length needed of fencing is:
[tex]p = 2\cdot (45\,ft+5\,ft)+2\cdot (18\,ft+5\,ft)[/tex]
[tex]p = 146\,ft[/tex]
The length of fencing is 146 feet.

Bob walks up to a tank of water that can hold 75 gallons. When it is active, a drain empties water from the tank at a constant rate. When Bob first sees the tank, it contains 15 gallons of water. 4 minutes later, the tank contains 12 gallons of water.
A. At what rate is the amount of water in the tank changing? answers: 3/4, -3, -3/4, 3
B. How many more minutes will it take for the tank to drain completely?
C. How many minutes before Bob arrived was the tank completely full?
Answer:
A) -3/4
B) 15 more minutes
C) 80 minutes
Step-by-step explanation:
A. rate of change = -3/4
B. 16 minutes
C. 1 hour 20 minutes
What is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given:
A) At first the tank contain 15 gallons of water.
After 4 minutes the tank contain 12 gallons of water.
So, rate of change
=12-15/4-0
=-3/4
=-3/4
B) now, Let x be the number of minutes will it take for the tank to drain completely.
So,
(3/4 gallons per minute) *x = 12 gallons
x = 12*4/3
x = 16 minutes
C) As, the tank has capacity of 75 gallons.
So, the tank of water is full when there is 10 gallons of water which is 60 gallons more.
Let 'y' be the number of minutes before Bob arrived when the water tank was completely full.
(3/4) (y) = 60
y = 60*4/3
y= 80 minutes
y= 1 hour 20 minutes

Rabbit populations can double every 30 days. If there are 26 rabbits on a farm, how many rabbits will be on the farm after 240 days?
Please use the Formula: Future Amount + [ ](1+__)^[ ]
Answer:
7680 rabbits
Step-by-step explanation:
Let y represent the number of rabbits after x days and let x represent the number of days. This is an exponential growth equation in the form:
[tex]y=ab^x[/tex]
Since there is an initial value of 26 rabbits on the farm and the rabbits double every 30 days, hence the equation becomes:
[tex]y=26(2^{(\frac{x}{30} )})\\\\for\ 240\ days, i.e\ x=240:\\\\y=26(2^\frac{240}{30} )\\\\y=7680\ rabbits[/tex]
