The correct values are;

a) y = - 10, x = - 1

b) y = - 9, x = 2/3

c) y = 2, x = 3

d) y = - 8, x = 2

e) y = 6.5 , x = 6

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

There are some expressions.

Now,

Find all the values after substitute the values as;

a. y = 6x + 8

When x = - 3;

y = 6 × - 3 + 8

y = - 18 + 8

y = - 10

When y = 2,

y = 6x + 8

2 = 6x + 8

2 - 8 = 6x

- 6 = 6x

x = - 1

b. y = 3x

When x = - 3;

y = 3 × - 3

y = - 9

When y = 2,

y = 3x

2 = 3x

x = 2/3

c. y = - x + 5

When x = - 3;

y =  - 3 + 5

y = 2

When y = 2,

y = - x + 5

2 = - x + 5

x = 5 - 2

x = 3

d. y = 2x - 2

When x = - 3;

y = 2 × - 3 - 2

y = - 6 - 2

y = - 8

When y = 2,

y = 2x - 2

2 = 2x - 2

2x = 2 + 2

2x = 4

x = 2

e. y = 1.5x + 11

When x = - 3;

y = 1.5 × - 3 + 11

y = - 4.5 + 11

y = 6.5

When y = 2,

y = 1.5x + 11

2 = 1.5x + 11

1.5x = 2 - 11

1.5x = - 9

x = 6

Thus, The correct values are;

a) y = - 10, x = - 1

b) y = - 9, x = 2/3

c) y = 2, x = 3

d) y = - 8, x = 2

e) y = 6.5 , x = 6

Step-by-step explanation:

Answer:

6x + 6 = 30

2x = 8

plz give brainlyist

Step-by-step explanation:

6x + 2 = 10

to get the first term to be 6x you need to mulitply by 3 but if you did then the equation would be 6x + 6 = 30 so it is not equivlent      

6x + 6 = 30

if you multiply both side by 3 you get 6x + 6 =  30

2x+8

if you subtract 2 from both sides you get 2x = 8

6x = 10

to get the first term to be 6x you need to mulitply by 3 but if you did then the equation would be 6x + 6 = 30 then if you subtract 6 from both sides you get 6x = 24 so it is not equivlent  

Answer:

The second stove had a higher temperature when the stoves were turned off.

The first stove cooled down at a faster rate.

Step-by-step explanation:

first stove: T(t) = 180 - 2.55t can also be written as T(t) = -2.55t + 180

(180 is the y-intercept; -2.55 is the slope)

second stove = T(t) = mt + 200

(0,200) (40,130)

[tex]\frac{200 - 130}{0 - 40}[/tex] = [tex]\frac{60}{-40}[/tex] = [tex]\frac{3}{-2}[/tex] = -1.5

T(t) = -1.5t + 200

Answer:

C. p = 1.72d

Step-by-step explanation:

The rate of change for the diver is 0.43. 0.43 x 4 = 1.72d.

The equation for the rate of change for the diver is 1.72d.

It is required to find the equation.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

The table shows the pressure in PSI for several depths of water.

For a submarine the pressure increases at 4 times the rate of a diver.

The water pressure in square inches for a submarine=p

The depth in feet =d

So we have to find the equation

The rate of change for the diver is

0.43. 0.43 x 4

= 1.72d.

Therefore, the equation for the rate of change for the diver is 1.72d.

Step-by-step explanation:

180-77=103

11x+11=103

-11 on both sides

11x=92

divide by 11 on both sides

77-11=66180

x=13

180-77-90=13 plug that in and you get it

11(13)+11=154

-90

im not sure if im correct but i hope this helps

Answer:

x = 25

Step-by-step explanation:

The sum of the angles of a triangle add to 180

We have a right triangle so one of the angles is 90degrees

90 + 2x + x+ 15 = 180

Combine like terms

105+3x = 180

Subtract 105 from each side

105+3x-105 = 180-105

3x = 75

Divide by 3

3x/3 = 75/3

x = 25

Answer:

So the inside of a triangle will equal 180 degrees so, you would set up your equation as 90+2x+(x+15)= 180

you then solve that equation let me know if you didn't get the equation solved.

Answer:

5.33 unit

Step-by-step explanation:

logically FA = EA - EF = 13.33-8 = 5.33 units

Since, E, F and A all lie on the same line EA . The information ED=  units is redundant. Therefore we can say that FA= 5.33 unit

The length of FA is 5.33 units

The given parameters are:

[tex]\mathbf{EF = 8}[/tex]

[tex]\mathbf{ED = 10}[/tex]

[tex]\mathbf{EA = 13.33}[/tex]

EF and EA implies that point E is between line FA

So, the length of FA is calculated using:

[tex]\mathbf{FA = EA - EF}[/tex]

Substitute known values

[tex]\mathbf{FA = 13.33 - 8}[/tex]

Subtract

[tex]\mathbf{FA = 5.33}[/tex]

Hence, the length of FA is 5.33 units

Answer:

money saved by james = 30/2 = 15

equation used

money with James  = 3/4 (money with sister)

x/2 + 30 =3/4( x + 30 )

Step-by-step explanation:

Let money saved by sister be x

given

James has saved half the amount of money as his sister has saved.

Money saved by James = x/2

Total money saved by both of them = x + x/2

If they both save 30 more

Then

money with sister = x + 30

money with james = x/2 + 30

given that If they both save 30 more, james will have saved 3/4 as much as her sister

thus,

money with james  = 3/4 (money with sister)

x/2 + 30 =3/4( x + 30 )

=> 4(x+30*2) /2 = 3x+90

=> 2x + 120 = 3x + 90

=> 3x-2x = 120-90

=> x = 30

Thus,

money saved by james = 30/2 = 15

equation used

money with james  = 3/4 (money with sister)

x/2 + 30 =3/4( x + 30 )

Answer: You can solve this using a graphing calculator or an online calculator.

Step-by-step explanation:

1. Solve each equation for y:

x - 7 = 2y so y = (1/2)x - (7/2)

3x - 21 = 2y so y = (3/2)x - (21/2)

2. Graph the 2 equations

3. Find the intersection using the calculator

They intersect at (7,0). Those values of y make both of these equations true.

You can check this by plugging the values in:

(7) - 2(0) = 7   That's true

2(7) - 2(0) = 21   That's also true

Any values that make both equations true are solutions. Each of these equations is linear, and the lines in the graph just cross once, so there is one solution to this system of equations.

Step-by-step explanation:

3/6=k/7

cross multiply then

6k=21

divide by the coefficient of k

k=3.5
