In the figure find the value of x and y

Answer:

B. ( –3, –4)

C. ( 4, 17 )

Step-by-step explanation:

Function: y = 3x + 5

Using method of elimination

A. (2, –1)

x = 2, y = -1

-1 = 3 (2) + 5

-1 ≠ 11

This option is incorrect!

B. ( –3, –4)

x = -3, y = -4

-4 = 3 (-3) + 5

-4 = - 9 + 5

-4 = -4

This option is correct!

C. ( 4, 17 )

x = 4, y = 17

17 = 3 (4) + 5

17 = 12 + 5

17 = 17

This option is correct!

D. ( 3, 8 )

x = 3, y = 8

8 = 3 (3) + 5

8 = 9 + 5

8 = 14

This option is incorrect!

Answer:

$12.3

Step-by-step explanation:

Given data

We are given that the function for the charge is expressed as

y=0.8x+3

Where y is the total cost for a ride

X is the distance of the ride

Say x= 12 miles

Hence the total cost of the ride is

Y= 0.8*12+3

Y= 9.6+3

Y= $12.3

Hence a 12 miles Distance will cost $12.3

Answer:

i think that they will get the same amount after a week's pay

Answer:

10 weeks

Step-by-step explanation:

You start by looking for the number that would help make these equal. it would have to be a number that ended with a 5 or 0. that would be 10. 10x7=70. 70+50=120

120

then 10x10=100+20

120

they will be the same at

10

Answer:

x = 13.5 and y = 7

Step-by-step explanation:

Given equations are :

x + y = 20.5 ...(1)

x − y = 6.5 ...(2)

Add equation (1) and (2).

x + y + x- y = 20.5+6.5

2x = 27

x = 13.5

Put the value of x in equation (1).

13.5 + y = 20.5

y = 20.5-13.5

y = 7

Hence, the values of x and y are 13.5 and 7.

Step-by-step explanation:

Answer:

7) 16 sq units

8) L = 22 cm

Step-by-step explanation:

7) A = 1/2h·(sum of bases)

= 1/2(4)(5+3)

= 2(8) or 16 sq units

8) A (trapezoid) = 1/2(7)(10+12)

= 1/2(22)(7)

= 11(7) or 77 sq cm

To find 'l' in triangle:

A = 1/2·L·7

77 = 7L /2

7L = 154

L = 22 cm

Answer:

2 : 5

Step-by-step explanation:

In order to obtain the ratio between numbers, we divide by the largest common factor between both.

In this question, the numbers are;

36 : 90

The largest common faction is 18. Dividing both numbers by 18, we have;

36 / 18 : 90 / 18

2 : 5

The ratio is; 2 : 5

the answer is probably b

Answer:

x = 2.5

Step-by-step explanation:

2.4x - 6 = 0

2.4x - 6 + 6 = 0 + 6

2.4x = 0 + 6

2.4x = 6

2.4x ÷ 2.4 = 6 ÷ 2.4

x = 6 ÷ 2.4

x = 2.5

Answer:

13.6

Step-by-step explanation:

A= Pe^ rt

A=9070   P=7300   t= .016

9070 = 7300e^0.016t

divide by 7300

1.24246575342= e^0.016t

ln(1.24246575342)= ln e^0.016t

ln(1.24246575342)= 0.016t

divide by 0.016

t = 13.6

Answer:

16 is double 8, so just double the price: 2.64 x 2= $5.28

Answer:14x+4

Step-by-step explanation:

edit: the answer is 14x + 4

(the reason i edited was to cause less confusion)

Answer:

1) We have the system:

5*x - 3*y = 15

4*x + 3*y = 6

To solve this, we first need to isolate one of the variables in one of the equations, let's isolate x in the first equation:

x = 15/5 + (3/5)*y = 3 + (3/5)*y

Now we can replace this in the other equation to get:

4*( 3 + (3/5)*y) + 3*y = 6

and solve this for y.

12 + (12/5)*y  + 3*y = 6

(12/5 + 3)*y = 6 - 12 = -6

(12/5 + 15/5)*y = -6

(27/5)*y = -6

y = -6*(5/27) = 1.11

Now we can replace this in the equation:

x = 3 + (3/5)*y

To get the value of x.

x = 3 + (3/5)*1.11 = 3.67

Then the solution of this system is the point (3.67, 1.11)

2) Now we have the system:

2*x + 5*y = 26

4*x + 3*y = 24

The solution method is the same as before:

x = 26/2 - (5/2)*y = 13 - (5/2)*y

Now we replace this in the other equation:

4*( 13 - (5/2)*y) + 3*y = 24

52 - 10*y + 3*y = 24

52 - 7*y = 24

52 - 24 = 7*y

28 = 7*y

28/7 = y

4 = y

now we replace this in the equatio:

x = 13 - (5/2)*y

x = 13 - (5/2)*4 = 13 - 10 = 3

The solution of this sytem is (3, 4)

3) Now we have the system:

3*x + 3*y = 39

2*x - 3*y = -2

first we isolate x in the first equation:

x = 39/3 - 3*y/3 = 13 - y

Now we can replace this in the other equation:

2*(13 - y) - 3*y = -2

26 - 2*y - 3*y = -2

26 - 5*y = -2

26 + 2 = 5*y

28 = 5*y

28/5 = y = 5.6

Now we can replace this in the equation:

x = 13 - y

To get the x-value

x = 13 - 5.6 = 7.4

Then the solution for this system is (7.4, 5.6)

Answer:

120

Step-by-step explanation:

first, divide 48 by 2 since its 2.5. since theres a half. then you do 48+48+24. you double 48 and then add the half(which is 24) and that equals 120

hope this helpsss

Answer:

K=0.25

Step-by-step explanation:

Well the realationship in the problem y=kx. so now we substitute the numbers so that the equation is now -1/2=-2k

-1/2=-2k
