Triangle ABC is translated 6 units to the left and 1 unit up to create
Answer:
can you add a picture of the triangle
Step-by-step explanation:
Given the following formula, solve for a.
s=a+b+c/2
We can rearrange it to the standard form perimeter a = s - b - C/2
In arithmetic, what is a perimeter?
The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.
The answer to your question is a = s - b - C/2
To solve for "a", we must get "a" on it's own side of the equal sign. We can first subtract "s" from both sides:
0 = a + b + C/2 - s
Then, we can subtract a from both sides:
-a = b + C/2 - s
Finally, we divide both sides by -1, so a is by itself.
a = -b - C/2 + s
And we can rearrange it to the standard form:
a = s - b - C/2

The two equations that represent the remaining angle relationships are
x = 2(y + z) - 20 and x = 3z - 20
Writing equationsFrom the question, we are to determine the two equations that represent the remaining angle relationships
From the given information, we have that
x is the largest angle, y is the next largest angle and z is the smallest angle
Also, from the information,
"The measure of the largest angle is 20 degrees less than twice the sum of the measure of the other two angles"
That is,
x = 2(y + z) - 20
and
"The largest angle is 3 times the smaller angle minus 20 degrees"
x = 3z - 20
Hence, the two equations that represent the remaining angle relationships are x = 2(y + z) - 20 and x = 3z - 20

= (69 - 45) + (1/3 - 14/15)
= 24 + 1 x 5/3 x 5 - 14/15
= 24 + 5/15 - 14/15
= 24 + 5 - 14/15

B. f(x)=1-3x + x²
C. f(x)=9+x¹
D. f(x) = 2x+5
1. As x gets larger and larger in either the positive or negative direction, f(x) gets larger and
larger in the positive direction.
2. As x gets larger and larger in the positive direction, f(x) gets larger and larger in the
positive direction. As x gets larger and larger in the negative direction, f(x) gets larger and

4. As x gets larger and larger in either the positive or negative direction, f(x) gets larger and
larger in the negative direction.
End behavior of the polynomials f(x) = 2x² + 3x + x² - 1 and f(x) = 1 - 3x + x² is; As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more positive.
How to describe the end behavior of a Polynomial?
A) We are given the polynomial; f(x) = 2x² + 3x + x² - 1
This is a second degree polynomial with a positive leading coefficient. Thus, the end behavior is; As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more positive.
B) We are given the polynomial; f(x) = 1 - 3x + x²
This is a second degree polynomial with a positive leading coefficient. Thus, the end behavior is; As x gets larger and larger in the positive direction, f(x) gets more positive. As x gets larger and larger in the negative direction, f(x) gets more positive.
C) We are given the polynomial; f(x) = 9 + x¹
This is a first degree polynomial with a positive leading coefficient. Thus, the end behavior is; As x gets larger and larger in either the positive or negative direction, f(x) gets larger and larger in the negative direction.
D) f(x) = 2x + 5
This is a first degree polynomial with a positive leading coefficient. Thus, the end behavior is; As x gets larger and larger in either the positive or negative direction, f(x) gets larger and larger in the negative direction.

Maria uses 2/3 cup of powdered mix for every 2 gallons of water. Franco uses 1 1/4 cups of powdered mix for every 5 gallons of water. What is the strength of each sports drink?
The strength ratio of each sports drink is 4:3.
What is ratio ?Ratio can be defined as comparison of two or more similar quantities.
According to the given question Maria uses 2/3 cup of powdered mix for every 2 gallons of water.
Therefore the no. of cups of powdered mix per gallon in Maria's sports drink is
= (2/3)÷2
= (2/3)×(1/2)
= 2/6.
= 1/3 cups per gallon of sport drink.
In case of Franco the no. of cups of mix in his sport drink per gallon is
=(5/4)÷5
= 5/4×1/5
= 5/20
= 1/4 cups per gallon of sport drink.
∴ The strength of each sport drink is
= 1/3:1/4

Ezra and his wife’s monthly payment includes $2,165.61 for principal and interest, as well one twelfth of the annual property taxes of $6,478.50 and one twelfth of the annual insurance premium on the property of $2,186. What is their total monthly payment?
Using proportions, it is found that their total monthly payment is of $2,887.37.
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, the payments are given as follows:
$2,165.61 for principal and interest.1/12 = 0.0833 of $6,478.50 for taxes.1/12 = 0.0833 of $2,186 for insurance.Hence:
2165.62 + 0.0833 x 6478.5 + 0.0833 x 2186 = $2,887.37
Their total monthly payment is of $2,887.37.

Assume running consumes 111 Calories per mile. If you run 7-minute miles, what is your average power output, in watts?
By changing units from calories per minute to watts, we conclude that your power output is 1.11 Watts.
How to get the average power output?
Power is the ratio between energy consumed and the time in which it was consumed.
Here we know that you consume 111 calories per mile, and you run a mile in 7 minutes, then your power is:
P = (111 cal)/(7 min) = 15.86 cal/min
Now, we know that:
1 watt = 14.33 cal/min
Then we can rewrite our power as:
P = 15.86 cal/min = (15.86/14.33) W = 1.11 W
Your power output is 1.11 watts.

Multiply both sides of the equation by (1 + rt)
So, we have
P(1 + rt) - A
Divide both sides by P
So, we have
1 + rt = A/P
Subtract 1 from both sides
rt = A/P - 1

net profit by subtracting cost from sales. Find the polynomial which models the
company's sales in thousands of dollars.
The polynomial which models the company's sales in thousands of dollars will be 4.4x² + 4x.
What is a profit?A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.
The profit is given as,
Profit = Selling price - Cost price
Sales volume for an auto manufacturer may be calculated as 7.8x² + 3.2x + 3.5 and costs as 3.4x² - 0.8x + 3.5.
The net profit by subtracting cost from sales will be
Net profit = (7.8x² + 3.2x + 3.5) - (3.4x² - 0.8x + 3.5)
Net profit = 7.8x² + 3.2x + 3.5 - 3.4x² + 0.8x - 3.5
Net profit = 4.4x² + 4x
