Answer:

x=−2

y=7

Step-by-step explanation:

5x+2y=4

x−3y=−23

In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

5x+2y=4,x−3y=−23

To make 5x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 5.

5x+2y=4,5x+5(−3)y=5(−23)

Simplify.

5x+2y=4,5x−15y=−115

Subtract 5x−15y=−115 from 5x+2y=4 by subtracting like terms on each side of the equal sign.

5x−5x+2y+15y=4+115

Add 5x to −5x. Terms 5x and −5x cancel out, leaving an equation with only one variable that can be solved.

2y+15y=4+115

Add 2y to 15y.

17y=4+115

Add 4 to 115.

17y=119

Divide both sides by 17.

y=7

Substitute 7 for y in x−3y=−23. Because the resulting equation contains only one variable, you can solve for x directly.

x−3×7=−23

Multiply −3 times 7.

x−21=−23

Add 21 to both sides of the equation.

x=−2

The system is now solved.

x=−2,y=7

Answer:

nth term = 0.8 * -5^(n - 1)

First five terms are: 0.8, -4,

20, -100, 500

Step-by-step explanation:

First term, a1 = 0.8

Common ratio, r = -5

a1 = 0.8

Second term = ar

= 0.8 * -5

= -4

Third term = ar²

= 0.8 * -5²

= 0.8 * 25

= 20

Fourth term = ar³

= 0.8 * -5³

= 0.8 * -125

= -100

Fifth term = ar⁴

= 0.8 * -5⁴

= 0.8 * 625

= 500

First five terms are: 0.8, -4,

20, -100, 500

nth term = ar^(n - 1)

= 0.8 * -5^(n - 1)

nth term = 0.8 * -5^(n - 1)

Answer:

L= 90, M=53, K=37

Step-by-step explanation:

Tilt your phone/computer to the right, and you'll see the 90° angle for L. Now you're left with two more, and just compare which angle is bigger, K or M. M is bigger, so you apply the bigger number out of the you got which is 53. Now no doubts, K is 37.

Answer:

1) [tex]3x^{2}[/tex]-19x-14

2) x=0, x=3

Step-by-step explanation:

1) (3x+2)(x-7)

Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.

[tex]3x^{2}[/tex] - 21x + 2x -14

Combine like terms

[tex]3x^{2}[/tex] - 19x - 14

2)

In order to find the factors of x, set the expression equal to 0.

[tex]3x^{2}[/tex] - 9x = 0

Factor out the highest common multiple (3x)

3x(x-3) = 0

In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3

Or 3x = 0 -> x = 0

Hope this helps!

Answer:

3. y=2x + 4

Step-by-step explanation:

We know that b is 4 because of the point (0,4)

Now count the slope by using rise over run

We go up 2 and over 1 so the slope is 2

Answer:

n=40

Step-by-step explanation:

divide 32 by 80

32/80=0.4

0.4x100=40

n=40

Answer:

part A: the warmer the city temp was the more lemonade that was sold so a hotter day will sell more lemonade

part B: i used points 40,8 and 90,20 and got m= 25/6 then i did y=mx+b

90=25/6(1)+b

90/1=25/6+b

25/6   25/6

and then B= 21.6

Step-by-step explanation: im not sure if i did it right so i would check i havent done this since like the 6th grade like 4 years or so ago lol

Answer:

Step-by-step explanation:

Answer:

39

Step-by-step explanation:

the answer is going up by the numbers 1,2,3,4...

you start with 4 and go up by 2

you then get 6 that's when you count up 3

you get 9 and then count up 4

which is 13 count up 5

18 count up 6

24 count up 7

31 count up 8

Answer:

28

Step-by-step explanation:

So if it's a complementary angle is equals 90 degrees total. So subtract 62 from 90. 90-62=28

Answer:

3 more months to get $250.

Step-by-step explanation:

She had 100 in her account. Thats 2 months. 3 months would give her 150 more dollars. So 100 + 150 = 250

Answer and Step-by-step explanation:

So, you would do 100 times 31.8, which is 3180, that'll be the area of the rectangle.

Now, the semicircles. They together form a circle.

So, we do pi times d (diameter), which is 3.14 times 31.8 = 99.852

Now we add them together.

99.852 + 3180 = 3279.85 (rounded to the nearest hundredth of a meter)

The rectangle area is 3180.

The Semi circles' combined area is 99.85.

The total area of the figure is 3279.85.

I hope this helps! Have a great day!

Answer:

Step-by-step explanation:

according to the question

the area of full shape

=[tex]\text{area of the rectangle+the area of the full circle}[/tex]

=(100×31.8)+(π×(31.8/2)²)

=3180+(3.14×(15.9)²

=3180+(3.14×252.81)

=3180+793.8234

=3973.8234

=3973.82
