Marta saved up money in order to buy a shirt she wanted. She spent $35.22 on the shirt.
Afterwards she had $12.75 left of what she had saved. Let m be the original amount of money
hat Marta had saved.
a) Write an equation that models the information given in this problem. Please help quickly please
Answers
$$
m - 35.22 = 12.75
$$
This equation says that the original amount of money Marta had saved, m, minus the amount she spent on the shirt, $35.22, is equal to the amount she had left, $12.75[1].
Answer: m=35.22+12.75
Step-by-step explanation:
Well we should first assume that we don't know what she originally had altogether, so I would assume this would start as a m=... sort of problem. Since we know she spent 35.22 on the shirt and know she had 12.75 left over we can assume when these totals are added we get her original amount of money that was saved up.
m = original amount saved up
Spent = 35.22
Left = 12.75
m=35.22+12.75

Answers
The cost of one keelboat is $7950
Given, A community boating center had $12,500.
It bought 3 surf skis and 1 keelboat and had $265 left over.
The keelboat cost $6,455 more than a surf ski.
Let the cost of one surf ski be x,
According to question,
cost of one keelboat = x + 6455
also, 3x + (x + 6455) + 265 = 12500
4x + 6520 = 12500
4x = 5980
x = 1495
So, the cost of one surf ski is $1495
and the cost of one keelboat is 1495 + 6455
= $7950
Hence, the cost of one keelboat is $7950

They are similar because AB is four more than ED, AC is three more than DF, and BC is three more than EF.
To determine if two triangles are similar, we need to compare the ratios of the corresponding sides.
In this case, the given information allows us to compare the lengths of the corresponding sides of triangle ABC and triangle DEF.
We have:
AB = 16 and ED = 12 (AB is four more than ED)
AC = 12 and DF = 9 (AC is three more than DF)
BC = 1 and EF = 9 (BC is three more than EF)
The corresponding sides are proportional because the ratios of the lengths are consistent:
AB/ED = 16/12 = 4/3
AC/DF = 12/9 = 4/3
BC/EF = 1/9
Since the ratios of the corresponding sides are the same, we can conclude that triangle ABC and triangle DEF are similar

The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.
Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.
We have:
z₁ = 7(cos(577°) + i sin(577°))
Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.
From the given information, we have:
z₂ = 21(cos(-7°) + i sin(-77°))
To find the quotient, we divide z₁ by z₂:
z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]
Substituting the given values, we have:
z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]
= (7/21) * [cos(584°) + i sin(584°)]
The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

How would you solve
"if f(x) / (x - 2) = x ^ 3 + 2x - 4 + 13/(x - 2) what is f(2)"
and
"if f(x) / (x + 3) = 3x ^ 2 - 4x + 2 what is f(-3)"
Answers
The denominator is zero (0/0 is undefined), we cannot determine the exact value of f(-3) using this equation.
To solve the given equations, we need to find the value of the function f(x) for specific values of x.
"If f(x) / (x - 2) = x³ + 2x - 4 + 13/(x - 2), what is f(2)?"
To find f(2), we can substitute x = 2 into the equation and solve for f(2).
Plugging in x = 2, we get:
f(2) / (2 - 2) = 2³ + 2(2) - 4 + 13/(2 - 2)
Since the denominator is zero (2 - 2 = 0), the equation is undefined. Therefore, there is no solution for f(2) in this case.
"If f(x) / (x + 3) = 3x² - 4x + 2, what is f(-3)?"
To find f(-3), we can substitute x = -3 into the equation and solve for f(-3).
Plugging in x = -3, we get:
f(-3) / (-3 + 3) = 3(-3)² - 4(-3) + 2
Simplifying, we have:
f(-3) / 0 = 3(9) + 12 + 2
f(-3) / 0 = 27 + 12 + 2
f(-3) / 0 = 41
Additional information or context is needed to solve for f(-3).

What is slope ?
A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).
1) slope, m = change in y/change in x = 3/1 = 3
y-intercept = b = 3
A line's slope intercept form is y=mx+b
Thus, the rule for the graph is y=3x+3
2) slope, m = change in y/change in x = 4/1 = 4
y-intercept = b = 10

The population of Placerville grew from 4360 a decade ago to 6590 today.
Answers
Answer: To find the percent increase in population, I used the following formula:
percent increase = (new value - old value) / old value * 100
In this case, the old value was the population from a decade ago (4360), and the new value was the current population (6590). So plugging these values into the formula, we get:
percent increase = (6590 - 4360) / 4360 * 100
percent increase = 51.38%
So the population of Placerville increased by approximately 51.38% over the past decade. The population of Placerville has increased by (6590 - 4360) = 2230 people over the past decade.

You start driving north for 24 miles, turn right, and drive east for another 10 miles. At
the end of driving, what is your straight line distance from your starting point?
Answers
Answer:
26 miles.
Step-by-step explanation:
To solve this problem, the Pythagorean theorem must be applied, which states that the hypotenuse squared of every right triangle is equal to the sum of its squared legs, that is, A^2 + B^2 = C^2 .
Therefore, applying this formula, to determine the distance in a straight line from the starting point to the driving end point, the following calculation must be performed:
24^2 + 10^2 = X^2
576 + 100 = X^2
√676 = X
26 = X
Thus, the distance between the two points is 26 miles.

Answers
Answer:
No, not necessarily
Step-by-step explanation:
If g(a) = 0, it is not necessarily that F(x) will have a vertical asymptote at x = a
For instance, assume the following conditions:
\(F(x) = \frac{f(x)}{g(x)}\\f(x) = x^3*(x-a)\\g(x) = x-a\)
In this conditions, g(a) = 0. F(a), however, can be written as:
\(F(x) = \frac{x^3*(x-a)}{x-a}\\F(a) = a^3\)
In this particular case, F(x = a) does not show a vertical asymptote.
