PLEASEE ANSWER ASAPP!!
The system of linear equations −3x + 2y = −6 and y equals negative one half times x plus 4 is graphed on a coordinate plane. Approximate the solution to the system.

Answers

Answer: the solution to the system of equations is approximately (3.5, 2.25)

Step-by-step explanation:

The first equation can be rewritten in the form y = mx + b, where m is the slope and b is the y-intercept, by solving for y:

-3x + 2y = -6

2y = 3x + 6

y = (3/2)x + 3

The second equation already has the form y = mx + b:

y = -1/2 x + 4

Now that both equations are in the form y = mx + b, we can graph them on a coordinate plane and find the point at which they intersect, which is the solution to the system. The x and y coordinates of the intersection point are the values that satisfy both equations simultaneously.

The x and y values of the intersection point can be found either by solving for x and y or by using the method of substitution.

By using substitution, we can substitute the value of y from the second equation into the first equation to solve for x:

-3x + 2(-1/2 x + 4) = -6

-3x + (-x + 8) = -6

-4x + 8 = -6

-4x = -14

x = 3.5

Now that we have found x, we can substitute it into either equation to find y:

y = -1/2 x + 4

y = -1/2 * 3.5 + 4

y = 2.25

So, the solution to the system of equations is approximately (3.5, 2.25).

What can you do to get 2x alone on the left side of the equation? Fill in the blanks below to show what you would do. Then, simplify the equation.

equation
82.5 + 8(0.25x) = 338.5

Answers

Answer: 82.5+8(0.25x)+2x=338.5

Subtract 82.5 on both side

Multiply 8 and 0.25 then add 2x

4x=338.5-82.5

Divide by 4

X=64

Step-by-step explanation:

x=128

Subtract both sides by 82.5




Divide both sides by 2

2x/2 = 256/2

X=128

I need to find whether its a adjacent angle or vertical on both

Answers

1.) is a vertical angle; X=113

2.) is a adjacent angle; X=28

Answer:

1.  Vertical angles

x = 113°

2. Adjacent angles

x = 28

Step-by-step explanation:

1)

Vertical angles have the same measurement.  They are across from one another.

2) Adjacent angles are next to each other.

These angles are complementary.  That means that together they add to 90

56 + x + 6 = 90  Combine like terms

62 + x = 90  Subtract 62 from both sides

62 - 62 + x = 90 - 62

x = 28

There are 2 2/10 and 2 8/10 which makes 2

There is a 4/10 and a 6/10 which makes 1

There are 2 5/10 which makes 1

If the question is how many pints are in each drink for them all to be equal it would be 5/10 or 1/2 pints each because there are 5 pints and 10 people with milk.

A. 15 cakes cost $37.50. 30 cakes cost $75. 50 gigs cost $125
B. 15 cakes cost $99.50 30 gigs cost $137. 50 gigs cost $187
C. 15 cakes cost $99.50. There any cakes cost $75. 50 gigs cost $125

Answers

The correct option is B.

Here's the breakdown of the cost calculation:

15 cakes:

Cake mix: $2.50 x 15 = $37.50

Baking pans: $62

Total: $37.50 + $62 = $99.50

30 cakes:

Cake mix: $2.50 x 30 = $75

Baking pans: $62

Total: $75 + $62 = $137

50 cakes:

Cake mix: $2.50 x 50 = $125

Baking pans: $62

Total: $125 + $62 = $187

So the correct option is B
