Answer:
Answer: y=3/2x+1
To find a line that is perpendicular, invert the slope and multiply by -1
so the original slope is -2/3,
invert it to get -3/2 then multiply by -1 to get 3/2
Put the given point (-2,-2) and the new slope into point intercept form: y+2=3/2(x+2)
Rewrite in standard form to get y=3/2x+1
It has been estimated that a certain stream can support 85,000 fish if it is pollution-free. It has further been estimated that for each ton of pollutants in the stream, 1700 fewer fish can be supported. Assuming the relationship is linear, write the equation that gives the population of fish p in terms of the tons of pollutants x.
Answer:
[tex]p = 85000 - 1700x[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Fish = 85000[/tex]
[tex]Rate = 1700[/tex]
Required
Determine the equation
For 1 ton, there is a reduction of 1700 fishes
This implies that:
For x tons, there will be a reduction of 1700x fishes
So, the function is:
[tex]p = Initial\ Fishes - Rate * x[/tex]
We used minus because the number of fishes reduced.
So, we have:
[tex]p = 85000 - 1700*x[/tex]
[tex]p = 85000 - 1700x[/tex]
Hence, the function is: [tex]p = 85000 - 1700x[/tex]

Answer:
Calzones are $ 8 and an Empanada costs $12
Step-by-step explanation:
2x+3y=52
4x+3y=68
Multiply by -1
-2x-3y=-52
4x+3y=68
combine
2x=16
x=8
plug in 8
4(8)+3y=68
32+3y=68
3y=36
y=12
Step-by-step explanation:
step 1. 2c + 3e = 52, 4c + 3e = 68.
step 2. this is a system of equations. solve the system.
step 3. subtract the 1st equation from the 2nd.
step 4. 2c = 16, therefore c = 8.
step 5. 2(8) + 3e = 52. 3e = 36. e = 12.
step 6. calzones = 8, empanadas = 12.

Find the midpoint of the segment with the following endpoints
(9.9) and (1.-1)
Answer:
(5,4)
Step-by-step explanation:
To find midpoint you just find out how far apart the points are and divide it by half. For example our x values are 9 and 1. 9 and 1 are 8 points away. Half of 8 is four so 9-4 is 5. Remember midpoint is the MIDDLE.

Example 2: Identify the reference angle.
A)
135°
B)
260°
C)
310
Answer:
A) 45
B) 80
C) 50
Step-by-step explanation:
When the terminal side is in the first quadrant (angles from 0° to 90°), our reference angle is the same as our given angle. This makes sense, since all the angles in the first quadrant are less than 90°.
When the terminal side is in the second quadrant (angles from 90° to 180°), our reference angle is 180° minus our given angle.
When the terminal side is in the third quadrant (angles from 180° to 270°), our reference angle is our given angle minus 180°.
When the terminal side is in the fourth quadrant (angles from 270° to 360°), our reference angle is 360° minus our given angle.

44 is 11% of what number?
Answer:
400
Step-by-step explanation:
look it up. it says 400.
The required number is 400 for which 44 is 11%.
The percentage is a way to express a proportion or a fraction as a fraction of 100. It is commonly used to compare values or quantities relative to a whole or a total.
To calculate a percentage, you typically divide a part or a quantity by the whole or the total and then multiply the result by 100. The resulting value represents the percentage equivalent of the part or quantity.
It implies that a percentage value represents a certain number out of 100 parts.
Given that 44 is 11% of the number. The unknown number is calculated as,
x (11%) = 44
[tex]x \times \dfrac{11}{100} = 44\\x = \dfrac{44\times100}{11}\\x=400[/tex]
Therefore, the number is 400.

A large pizza costs $17.99. A second large pizza is 14 off. Using an estimate, approximately how much will it cost for 2 large pizzas?
Answer:
$22
Step-by-step explanation:

a second large pizza is 14 dollars off of the original price of 18 so 4
18+4 is 22
so 2 large pizzas would cost $22
The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 22 more than the second. Let x, y, and z represent the measures of the first second, and third angles, respectively. Find the measures of the three angles.
Answer:
x=30°, y=64°, z=86°
Step-by-step explanation:
Make a system of equations using the information given.
x + y + z = 180 <-- from "the sum of interior angles equals 180 degrees"
y + z = 5x <-- from "sum second angle and third angles is five times the first angle"
z = y + 22 <-- from "the third angle is 22 more than the second"
Eliminating the x variable to makes the equations easier to solve.
5x + 5y + 5z = 900
-(5x = z + y)
= 5y + 5z = 900 - z - y
= 6y + 6z = 900
= y + z = 150
Now substitute z for (y+22)
y + (y + 22) = 150
2y + 22 = 150
2y = 128
y = 64
Now find z when y=64
z = (64) + 22
z = 86
Finally, plug in z and y into one of the equations with x and evaluate for x.
x + 64 + 86 = 180
x + 150 = 180
x = 30

Answer:
x = 14√2y = 14z = 14√3Step-by-step explanation:
These are two "special triangles." The ratios of side lengths are numbers not difficult to remember. They can save a lot of work in problems like this.
Ratio of side lengths in 45°-45°-90° isosceles right triangle: 1 : 1 : √2.
Ratio of side lengths in 30°-60°-90° right triangle: 1 : √3 : 2.
__
The side marked x has the same length as the side marked 14√2.
x = 14√2
The unmarked hypotenuse of both triangles is √2 times the marked side length, so is (14√2)(√2) = 28.
The side marked y is half the length of the hypotenuse of that triangles so is ...
y = 28/2
y = 14
And the side marked z is √3 times the short side of the 30°-60°-90° triangle, so is ...
z = 14√3
_____
Alternate solution
The mnemonic SOH CAH TOA can help you remember trig relationships. Here, 14√2 is opposite the given 45° angle, and x is adjacent. The trig relation is ...
Tan = Opposite/Adjacent
tan(45°) = 14√2/x
x = 14√2/tan(45°) = 14√2
__
To find y or z, we need to know the length of the hypotenuse in the 45° triangle. The given side is opposite the angle, so we can use the sine relation:
Sin = Opposite/Hypotenuse
hypotenuse = 14√2/sin(45°) = 28
Now, we can find y and z:
sin(30°) = y/hypotenuse
y = (28)sin(30°) = 14
cos(30°) = z/hypotenuse
z = (28)cos(30°) = 14√3
A baker makes apple tarts and apple pies each day. Each tart, t, requires 1 apple, and peach pie, p, requires 8 apples. The baker receives a shipment of 184 apples every day. If the baker makes no more than 40 tarts per day, which system of inequalities can be used to find the possible number of pies and tarts the baker can make?
t ≤ 40
p ≤ 184
t ≤ 40
8p ≤ 184
t ≤ 40
p + 8t ≤ 184
t ≤ 40
8p + t ≤ 184
the answer is D is the answer
Answer:
i think 8p+tLess equal to 184
The inequality system may be used to determine the maximum number of pies and tarts the baker is capable of producing is t ≤ 40 and 8p + t ≤ 184.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We need to define variables initially in this situation. Thus, we have the number of tarts and the number of pies, which are p and t respectively.
Apples are needed for each tart, abbreviated t, and for each pie, abbreviated p.
It is given that every day, a supply of 184 apples is sent to the baker
8p + t ≤ 184
The baker only produces up to 40 tarts every day as a result
t ≤ 40
Thus, the inequality system may be used to determine the maximum number of pies and tarts the baker is capable of producing is t ≤ 40 and 8p + t ≤ 184.

Step-by-step explanation:

(7x+1)
(10x-9)
Answer:
Step-by-step explanation:
Exterior angle property: Exterior angles equals the sum of remote angles
19x - 18 = 7x + 1 + 10x - 9
19x - 18 = 7x + 10x + 1 - 9 {Combine like terms}
19x - 18 = 17x - 8 {Subtract 17x from both sides}
19x - 17x - 18 = -8
2x - 18 = -8 {Add 18 to both sides}
2x = -8 + 18

The length of time, in hours, it takes a train to travel to city B varies inversely with the train’s speed. The train Carole is traveling on is moving at a speed of 70 miles per hour, and it takes her 4 hours to arrive. If the train Steve is traveling on is moving at a speed of 50 mph, how long will it take him to arrive at City B?
Answer:
Step-by-step explanation:
4 h × (70 mi)/h = 280 mi
280 mi × (1 h)/(50 mi) = 5.6 h
The time taken by him to arrive at City B will be 5.6 hours.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The time span, in hours, it takes a train to go to city B fluctuates contrarily with the train's speed.
V x T = Constant
The train Carole is going on is moving at a speed of 70 miles each hour, and it requires her 4 hours to show up. In the event that the train, Steve is going on, is moving at a speed of 50 mph.
Let 't' be the time. Then the equation is given as,
t x 50 = 4 x 70
50t = 280
t = 280 / 50
t = 28 / 5
t = 5.6 hours
The time taken by him to arrive at City B will be 5.6 hours.
