Step-by-step explanation:

Monthly net income = 30300/12 = $2525

Total monthly expenses = 1230+780+160 = $2170

Surplus = 2525 - 2170 = $355

If the range of the coordinate transformation (, ) = (−2,−3 +1) is (4, −2), (2, −5), (−6, 4), what is the domain?

Alex17521 [72]

Consider the below figure attached with this question.

Given:

The transformation is:

$f(x,y)=(-2x,-3y+1)$

The range is (4,-2), (2, −5), (−6, 4).

To find:

The domain of the transformation.

Solution:

We have,

$f(x,y)=(-2x,-3y+1)$

For the point (4,-2),

$(-2x,-3y+1)=(4,-2)$

On comparing both sides, we get

$-2x=4$

$x=\dfrac{4}{-2}$

$x=-2$

And,

$-3y+1=-2$

$-3y=-2-1$

$-3y=-3$

$y=\dfrac{-3}{-3}$

$y=1$

So, the domain of (4,-2) is (-2,1).

Similarly,

For the point (2,-5),

$(-2x,-3y+1)=(2,-5)$

On comparing both sides, we get $x=-1,y=2$ . So, the domain of (2,-5) is (-1,2).

For the point (-6,4),

$(-2x,-3y+1)=(-6,4)$

On comparing both sides, we get $x=3,y=-1$ . So, the domain of (-6,4) is (3,-1).

So, the domain of the given transformation is (-2, 1), (-1, 2), (3, -1).

Therefore, the correct option is A.

suppose you own a car that gets 35 miles to a gallon of gasoline and gasoline costs $1.25 per gallon. how many gallons of gas ca

valina [46]

The answer of your question is 20 gallons of gasoline. It just a simple division you just have to divide $25 which is the given money to buy an exact amount of gallon by $1.25 which is the price of each gallon. So you would come up to an answer of 20 gallons.

Please I beg you help me

Elena L [17]

Answer:

Option D

Step-by-step explanation:

Going through the choices will help determine which option best simulates the random selection of a voter.

Flip a coin three times, and assign outcomes as follows: HHH, HHT, or HTH = Nava; HTT, THH, or THT = Jensen; TTH = Moretti, TTT = Chang.

Given that it is a random selection of the 4 candidates, it means the probability of choosing either one of them is equivalent. From the option, it can be found that Nava and Jensen have a higher chance of being voted than Moretti and Chang, which would not fit the criteria of being randomly selected.

Roll a number cube, and assign outcomes as follows: 1 or 2 = Nava, 3 or 4 = Jensen, 5 = Moretti, 6 = Chang.

Again, Nava and Jensen have a higher chance of being voted than Moretti and Chang. Therefore, this is not the correct option to simulate random selections of the 4 candidates.

Roll a number cube, and assign outcomes as follows: 1, 2, or 3 = Nava, 4 = Jensen, 5 = Moretti, 6 = Chang.

Nava has a higher chance of being voted, so this option does not fit the stimulation.

Flip a coin twice, and assign outcomes as follows: HH = Nava, HT = Jensen, TH = Moretti, TT = Chang

In this scenario, all 4 candidates have an equal chance of being voted, so this option would best simulate the random selection of a voter from the city.

Hope this helps :)

Marcus and Jeremy both evaluated the expression −52 + 3. Marcus said the answer was −22. Jeremy said the answer was 28. Who is c

Artyom0805 [142]

Answer:

Alright, the answer to the equation -52+3= -49

Step-by-step explanation:

I don't know how the heck Marcus and Jeremy got -22 and 28 but both are wrong. If there were a picture so I could see their work, I would be able to figure it out.

Anyways, The math is:

-52 + 3 which is pretty much 52-3 and then the answer has a negative sign.

-52 goes up 3 because technically the negative sign is down. Counting up 3 from 52 equals -49.
