Solve 3x − 5y = 17
9x − 15y = −4

Answers

Answer 1

Answer:

3x - 5y = 17

3(9) - 5(2) = 17

27 - 10 = 17

x = 9

y = 2

---------------------

9x - 15y = -4

I believe this equation has no proper solution. Every "solution" I have found ends with repeating decimals & fractions.

The variables y and x have a proportional relationship, and y = 9 when x = 2. What is the value of y when x = 3? Enter your answer as a decimal in the box. ​

Answers

If they have a proportional relationship, then set them up as a proportion

9/2 = y/3.....9 to 2 = y to 3
cross multiply
(2)(y) = (9)(3)
2y = 27
y = 27/2
y = 13.5 <== so when x = 3, y = 13.5

A weather report stated that the monthly rain amounts for the past three months were 15.82 inches, 17.4 inches, and 9.56 inches.
What is the total amount of rainfall for the three months?
A. 27.12 inches
B. 41.178 inches
C. 42.42 inches
D. 42.78 inches

Answers

Answer:

42.78 inches

Step-by-step explanation:

The anount of rainfall for the past three months are

15.82 inches

17.4 inches

9.56 inches

Therefore the total amount of rainfall for the three months can be calculated as follows

= 15.82+17.4+9.56

= 42.78

Hence the total rainfall for three months 42.78 inches

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the
doghouse?

Answers

A: 59.5ft^2

You need to add the top length and the bottom length, and then multiply that answer by the vertical height of the shape.

7 + 10 = 17
17/2 = 8.5
8.5 x 7 = 59.5

You can also double check this by working out the area of the square and then the area of the triangle, and adding them together.

7 x 7 = 49
7 x 3 = 21
21/2 = 10.5
49 + 10.5 = 59.5

tan²Ф+sec²Ф=3


can someone solve this by finding all answers as the nearest whole degree

Answers

Recall that

tan²(x) + 1 = sec²(x)

for all x ≠ (2n + 1) 90°, where n is any integer. (That is, whenever x isn't an angle that is an odd multiple of 90°.)

Then

tan²(Φ) + sec²(Φ) = 3

tan²(Φ) + (tan²(Φ) + 1) = 3

2 tan²(Φ) + 1 = 3

2 tan²(Φ) = 2

tan²(Φ) = 1

tan(Φ) = ±√1

tan(Φ) = 1   or   tan(Φ) = -1

Φ = tan⁻¹(1) + n 180°   or   Φ = tan⁻¹(-1) + n 180°

Φ = 45° + n 180°   or   Φ = -45° + n 180°

The first family of solution is the set of angles

{…, -315°, -135°, 45°, 225°, 405°, …}

and the second family is the set

{…, -405°, -225°, -45°, 135°, 315°, …}

(showing the solutions for n = -2 to n = 2)

You can condense the solution set into one family by noticing each angle is 45° plus some multiple of 90°, so that

Φ = 45° + n 90°

If you're looking for solutions in a given range, such as 0 ≤ Φ < 360°, then

Φ = 45°, 135°, 225° or 315°

Jacob decided to start saving for college. After 3 months, he had saved $174. His friend Victoria was inspired to do the same. After 6 months, she had saved $360. If they are both saving money at a constant rate, how many more dollars per month does Victoria save than Jacob?

Answers

Answer:

$2 more.

Step-by-step explanation:

In this question, we have to find how much more money Victoria is saving.

We know that Jacob saved $174 in 3 months.

We also know that Victoria saved $360 in 6 months.

Lets find how much money they save per month:

Jacob:

174 ÷ 3 = 58

Victoria:

360 ÷ 6 = 60

Jacob is saving $58 per month and Victoria is saving $60 per month.

This means that Victoria is saving $2 more than Jacob per month.

Convert 3 weeks to hours. Use a lable.

Answers

Answer: 504 hours.

Step-by-step explanation: I am assuming it says, use a table not a lable.

Well, I can't make a table, so I will tell you where to put everything in a table.

We start with placing one day, one day is 24 hours. One day goes on the top, 24 hours goes on the bottom. Then, we know there are 7 days in a week, so we jump ahead, we multiply 24 by 7 and 1 by 7.

24 x 7 = 168 and 1 x 7 = 7

So for every week, it is 168 hours. Now we need to find three weeks. So we multiply 7 x 3 to get the days. which is 21. Now we need to multiply the hours by  the 3 weeks. So we multiply 168 by 3 which is 504.

So 504 hours are in 3 weeks.

what is the domain of h?

Answers

Answer:

The domain of given function is: [-7,7]

Step-by-step explanation:

Graphs can be used to determine the domain and range of a function.

On a graph, the values across the x-axis are domain and across y-axis are the range.

In the given graph, we can see that the graph starts from x=-7 and ends at x=7. The filled circle at both ends of the graph indicate that the values 7 and -7 are also included in the domain.

Hence,

The domain of given function is: [-7,7]

Find the slope intercept equation of the line

PLEASE SOMEONE HELP WHO UNDERSTANDS HOW TO DO THESE BECAUSE I KEEP GETTING THE WRONG ANSWER!!!

Answers

Step-by-step explanation:

For every 3 blocks across, the line graph goes up by 2 blocks. Therefore the slope of the line is 2/3.

The line also intercepts the y-axis at -3.

Hence the slope-intercept form is y = 2/3 x - 3.

When doing slope I suggest using slope triangles:) make a dot at -3, then go to the right 3 spaces, from this point go up 2 spaces and make another dot. Do that for as long as you need your line to be:) When you go up 2 spaces use that last dot and go over 3 spaces and up 2. Keep repeating
