Answer:
C
Step-by-step explanation:
Slope intercept form equation is y=mx+b
M=Slope
Slope equation is y2-y1 over x2-x1
So -16 - 47 over 2- (-4)
-63 over 6
Divide by 3 to simplify
= -21 over 2
Keep that as your answer for slope because a mixed number can't be used for slope but an improper fraction is perfectly fine
To find b use one point given (I chose to use (2, -16)
Plug that in and your slope to find b
-16= -21/2 (2) +b
-16= -21+b
+21 +21
5=b
Now plug that in and youre done
Y= -21/2x + 5

How will you know that the expression is a perfect square trinomial?
Answer:
An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.
Step-by-step explanation:
An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.
Now, the conditions for which an equation will be called a perfect square trinomial are;
i) It is of the form: ax² + bx + c
I) It satisfies the condition: b² = 4ac.
Thus, the perfect square formula could take the following forms:
(ax)² + 2abx + b² = (ax + b)²
Or
(ax)² − 2abx + b² = (ax − b)²
In Aunt Peggy’s backyard there are cows and chickens. There are 20 more chickens than cows. The total number of legs is 130. How many chickens and how many cows are there? (Each cow has 4 legs, each chicken has 2 legs.) PLZ HELP! Will mark brainliest
Answer:
There are 15 cows and 35 chickens
Step-by-step explanation:
So first you take 20 and multiply it by two since there are two legs on each chicken. You get 40.
Then you subtract 40 from 130. You get 90.
Since the cow has double the legs of the chicken, you can count the cow as two chicken.
You divide 90 by 3. You get 30.
To get the number of chicken you divide 30 by 2 and you get 15.
You add 15 and 20 together and you get 35 chickens.
To get the number of cows you divide 30 by 2 and you get 15.
So you have your answer. 35 chicken and 15 cows.

Step-by-step explanation:
Let's solve your inequality step-by-step.
122<−2(8x+3)
Step 1: Simplify both sides of the inequality.
122<−16x−6
Step 2: Flip the equation.
−16x−6>122
Step 3: Add 6 to both sides.
−16x−6+6>122+6
−16x>128
Step 4: Divide both sides by -16.
−16x /−16 > 128 /−16
x<−8
Please help? It’s a basic time question and I don’t get it. Either I’m really dumb or it’s to complicated
Answer: D 1 hour 56 minutes
Answer:
D. 1 hour 56 minutes
Step-by-step explanation:
Well, if you add 2 hours to 12:14, it would be 2:14, so you know it's less than 2 hours. B and D are the only choices that have 1 hour. So, if Aaron left at 2:10, you have to subtract 4 minutes from 2 hours. That would be 1 hour and 56 minutes Aaron spent at the mall.
I hope you understood!! (It's ok if you didn't get it...some things can seem complicated at first!) Have an amazing day C:

The gas tank on a car holds 13.4 gallons. If the car goes 335 miles on a single tank, how many miles per gallon does the car get? Provide an explanation of what the final answer means, in terms of the given problem. Show all work.
chile..
Answer:
The car gets 25 miles per gallon.
It means that for each gallon of gas the car uses, it will travel a distance of 25 miles.
Step-by-step explanation:
"Miles per gallon" is calculated by dividing the number of miles by the number of gallons.
mpg = (335 miles)/(13.4 gallons) = 25 miles per gallon
Answer:
The car gets 25 miles per gallon.
It means that for each gallon of gas the car uses, it will travel a distance of 25 miles.
Answer:
25
Step-by-step explanation:
You need to divide 335 miles by 13.4 to find the miles per gallon. 335 miles divided by 13.4 gallons is 25. So for every 25 miles you use 1 gallon.
Match each complex numbers with its corresponding distance to the origin
Answer:
2. z = 1 - 2·i → √5
3. z = 4 + 3·i → 54
4. z = 6 - 8·i → 10
1. z = √5 - i → √6
Step-by-step explanation:
1. z = √5 - i
The distance from the origin = √((√5)² +1²) = √(5 + (-1)²) = √6
Therefore, z = √5 - i → √6
2) z = 1 - 2·i
The distance from the origin = √(1² + (-2)²) = √5
Therefore, z = 1 - 2·i → √5
3) z = 4 + 3·i
The distance from the origin = √(4²+3²)) = √(16 + 9) = √25 = 5
Therefore, z = 4 + 3·i → 5
4) z = 6 - 8·i
The distance from the origin = √(6²+8²)) = √(36 + 64) = √100= 10
Therefore, z = 6 - 8·i → 10

Which equation models this?
Answer:
8X = 96 inch
Step-by-step explanation:
How its in the draw you have this situation then the equation that model is the next one:
2*(3X) + 2*X = 96 inch
6X + 2X = 96 inch
8X = 96 inch
We must multiply due that there is two sides that measure the same.

The straight line depreciation equation for
a motorcycle is y = -2.150x + 17,200.
(Express your answers as whole
numbers.)
a. What is the original price of the
motorcycle? $17,200.00
b. How much value does the motorcycle
lose per year?
c. How many years will it take for the
motorcycle to totally depreciate?
Given :
The straight line depreciation equation for a motorcycle is y = -2,150x + 17,200.
To Find :
a. What is the original price of the motorcycle? $17,200.00 ?
b. How much value does the motorcycle lose per year?
c. How many years will it take for the motorcycle to totally depreciate?
Solution :
y = -2,150x + 17,200.
Here, y is price and x is unit of time in years.
a)
We know, original price is given when x =0.
So, y = 0 + 17,200
y = $17,200.00
b)
Value motorcycle lose per year is coefficient of x i.e $-2,150.00
c)
Form total depreciate :
y = 0
0 = -2,150x + 17,200
x = 17,200÷2,150
x = 8 years.
Hence, this is the required solution.
it takes a biker 1/2 hours to ride 8/3 miles. What is the biker's rate,in miles per hour?
Answer:
The biker is traveling at [tex]5\frac{1}{3}[/tex] miles per hour.
Step-by-step explanation:
To find the rate, in miles per hour, you must use the formula r = d/t.
(r = rate)
(d = distance)
(t = time)
[tex]\frac{8}{3}[/tex] ÷ [tex]\frac{1}{2}[/tex] = [tex]5\frac{1}{3}[/tex]

The greater of two consecutive even integers is at most fifty less than five times the smaller. Which of these represents the inequality needed to solve for the smaller integer, x, as well as its solution?
Answer:
Inequality: 2x + 2 ≤ 5•2x - 50
Solution: x ∈ <6.5, ∞)
Step-by-step explanation:
2x - the smaller of consecutive even integers
2x+2 - the greater of consecutive even integers
5•2x - five times the smaller number
5•2x-50 - fifty less than five times the smaller number
"is at most" means is less or equal
2x + 2 ≤ 5•2x - 50
2x + 2 ≤ 10x - 50
-2 -2
2x ≤ 10x - 52
-10x -10x
-8x ≤ -52
÷(-8) ÷(-8)
x ≥ 6.5
x ∈ <6.5, ∞)
