2x+2y = 5
3x + 3y = 7

How many solutions does the system of equations above have?​

Answer:

  152°

Step-by-step explanation:

Angles B and A of the isosceles triangle have the same measures, so we have ...

  ∠B = ∠A

  (x -14)° = (x/2)°

  2x -28 = x . . . . . . divide by °, multiply by 2

  x = 28 . . . . . . . . . .add 28-x to both sides

Then the base angles, A and B, both have measure (x/2)° = 14°.

The third angle, C, will bring the total to 180°.

  ∠A + ∠B + ∠C = 180°

  ∠C = 180° - 2(14°)

  ∠C = 152°

Temperature dropped by 28°C in two hours

Answer:

It's D.

Step-by-step explanation:

If you want me to explain it, I will.  But it seems like you need the answer fast.  So if you still don't understand it later, then I will try to explain it...but it'll take some time.  :)

All you have to do is move all the points to the right 6 numbers because it says x+6.  For example, A is (-5,-1).  Move to the right 6 times, so (-5+6,-1) which is (1, -1).  So the new point of A is (1, -1).  Do the same with the others.  Now that we got the new rectangle in the fourth quadrant, you want to move it counterclockwise around the origin, which is 0.  Clockwise is like a clock, it goes around the middle going to the right.  Counterclowise is the same, except it goes to the left around the middle of the clock.  You can sort of apply that to this.  Go counterclockwise around the middle, in this case being the origin, 0. Move the rectangle up to the first quadrant because counterclockwise is going around to the left.  So, if the rectangle goes around to the left, then that means that it is now vertical...because it turns to the left making it straight if you go counterclockwise.  Now the point A is on the bottom left because the rectangle got turned.  If you turned it properly, then A should be at (1,1).  Apply the same thing to the other points.  D is the only one with point A being at the point (1,1), so that is correct.  Check the other points anyway.

Answer:

He will pay $922 Eve month where

$238.6667 is the interest in the payment

Step-by-step explanation:

Eric Shotwell borrows $24,600 from a certain bank. The interest charge amounts to $8,592 to be paid back in 36 months monthly.

Total money to be paid back

= 24600+8592

Total money to be paid back

= $33192

Now for each month in 36 months, a certain amount must be paid

That amount= 33192/36

= $922

But if the interest wasn't added

He'll pay= 24600/36

=$683.333

So the interest amount in the payment every month= 922-683.333.

= $238.6667

He will pay $922 Eve month where

$238.6667 is the interest in the payment

Total money to be paid back

= 24600+8592

= $33192

Now for each month in 36 months, a certain amount must be paid

That amount= [tex]33192\div36[/tex]

= $922

Now in the case when the interest wasn't added

He'll pay= [tex]24600\div 36[/tex]

=$683.333

So the interest amount in the payment every month is

= 922-683.333.

= $238.6667

Answer:

The depth of the swimming pool is 2.52 meters

Step-by-step explanation:

To solve this problem properly, the first thing we are to do is to ensure that we are working in the same units at all points in time during the solution.

First of all, we will convert the length and breadth of the pool from feet to yards.

1 foot = 0.3333 yards

30 feet = 10 yards

20 feet = 6.67 yards.

The next step is to find the depth of the swimming pool using the volume and the available dimensions.

From the dimensions given, we can tell that the swimming pool will have a cuboidal shape. This means that the volume will be = length X breadth X depth.

hence we have

184 = 10 X 6.67 X depth

depth = 2.76 yards.

The final step will be to convert the answer we obtained in yards to meters.

1 yard = 0.9144metres

2.76 yards = 2.52 meters

The depth of the swimming pool is 2.52 meters

Answer:

2x-14 = -37

Step-by-step explanation:

7x + 4 = -19 + 5x,

Subtract 5x from each side

7x-5x + 4 = -19 + 5x -5x

2x +4 = -19

Subtract 4 from each side

2x +4-4 = -19 -4

2x = -23

We want to find 2x -14

2x = -23

2x-14

-23-14

-37

Answer:

-37

Step-by-step explanation:

First, let's solve for x.

7x+4= -19+5x

Subtract 5x from both sides of the equation.

(7x-5x)+4= -19 (+5x-5x)

(7x-5x)+4=-19

2x+4=-19

Subtract 4 from both sides of the equation.

2x(+4-4)=(-19-4)

2x=(-19-4)

2x= -23

Divide both sides of the equation by 2.

2x/2= -23/2

x= -23/3

x= -11.5

Next, let's find what 2x-14 is equal to. Substitute -11.5 in for x.

2x-14

2(-11.5)-14

Multiply 2 and -11.5

-23-14

Subtract 14 from -23.

-37

2x-14 is equal to -37.

Complementary and adjacent.

The two angles are complementary because they add up to 90°. It's given that line JL is perpendicular to line MN, and perpendicular means they form a 90° angle where they intersect.

The two angles are adjacent because they are next to each other.

Answer:

B, Between -40 and -50

Step-by-step explanation:

Because, X lies between hask mark 4 and 5 to the left of 0, which would make it -40 and -50.

tan(20) can be written in fractions if you want to, but it is easier to write it in a decimal number when it is punched into a calculator.

Answer:

2(x-7) > 1/10

Step-by-step explanation:

The statement says, twice the difference of x and 7.  This implies that it wants the difference of x and 7, x - 7, and it wants twice that difference so:

2 ( x - 7 )

The statement continues that this twice the difference of x and 7 is greater than the reciprocal of 10.  The reciprocal of 10 is 0.1 or 1/10.

Hence, the statement should be written as such:

2 ( x - 7 ) > 1/10   OR    2 ( x - 7 ) > 0.1

Answer:

slope = 3

Step-by-step explanation:

The slope of a line parallel to the given equation share the same slope. Note the slope intercept formula:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

First, isolate the variable, y. Subtract 3x from both sides:

3x (-3x) - y = 1 (-3x)

-y = -3x + 1

Next, divide -1 from both sides:

(-y)/-1 = (-3x + 1)/-1

y = 3x - 1

You are solving for the slope of a line parallel to the given equation. Since you are solving for parallel, the slope would be shared.

3 would be the slope of the line.

1. Gender - qualitative

2. Age - Quantitative (Discrete)

3. Grade point Average - quantitative (Continuous )

4. Number of courses currently enrolled - quantitative (discreet)

5. Enrollment Status - qualitative

Step-by-step explanation:

Qualitative variables are those which are non-numeric, usually made up of strings or words. The quantitative variables are numeric, usually composed of digits and numbers.

Discreet variables have a finite or limited number of values which are countable as opposed to continuous variables with a non-finite range and hence, uncountable.

Gender is a qualitative variable as it is composed of non-nemeric labels which could be either Male or Female.

Age - is numeric and hence quantitative, since age is usually expressed in years, hence it is discreet.

Grade point Average is a quantitative and continuous variable due to its numeric nature and the fact that it can take up an infinite number of possible values including decimal values.

Number of courses enrolled is numeric can take a finite number of values, hence, it is discreet.

Enrollment status is qualitative as it is split into :

Part time or full time.

Answer:

$305

Step-by-step explanation:

You have to use the following formula to calculate the accrued amount:

A=P(1 + rt), where:

A= accrued amount

P= principal amount= $250

r= rate of interest= 11%

t= time period= 2 years

Now, you have to replace the values in the formula:

In this problem. we are required to re-write the given number from  scientific notation to standard notation and from standard notation to scientific notation

Exercise a

5.32 x 10-6 meters.

Since we have  10-6, this tells us that we are meant to shift 6 decimal points to the left that is we have

0.00000532 meters

Exercise b

In this example, we are expected to shift 5 decimals away from the decimal point to the right to arrive at the answer therefore we have to multiply by 10^5

hence the equivalent figure in scientific notation is   1.21*10^5 hence

121,000 meters.
