Put the following equation of a one into a slope -intercept form, simplifying all fractions.

8x+6y=-54

Answers

Answer:

y = -4/3x -9

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

8x+6y = -54

Subtract 8x from each side

8x+6y-8x = -8x-54

6y = -8x-54

Divide each side by 6

6y/6 = -8x/6 -54/6

y = -4/3x -9

Answer:

y = -4/3x - 9

Step-by-step explanation:

Putting this into 'y=mx+c' form:

i) Firstly, make it only y on the LHS:

6y = -8x-54

ii) Secondly, making the 'y' have a co-efficient of 1. This can be done by dividing both sides by 6:

6y/6 = -8x/6 - 54/6

y = -4/3x - 9

Hence,

y = -4/3x - 9

Answer:180 is what it need to be

Step-by-step explanation:

I need help with find this problem out

Answers

Ok so first, we know just by looking that QT is 180° since it’s a fraught angle. If you subtract angle QRS from QT, you’ll get the value for angle SRT. 180-162 is 18 so SRT IS 18°. The other angle of the triangle is already given to us as 130°. Since all three angles of a triangle add up to 180°, we can subtract the two angles to get the remaining one. 180-130-18 is 32 so the missing angle is 32°
Hope this helped :)

Answer:

Step-by-step explanation:

Hi there!

∠SRQ = 162°

∠STR = 130°

∠RST = ?

Now;

∠SRQ = ∠RST+∠STR   [external angle is equal to the sum of opposite interior angles of triangle]

∠RST = ∠SRQ-∠STR

∠RST = 162°-130°

Therefore, the measure of ∠RST is 32°.

Hope it helps!

What is the slope of this line?
a. -1/3

b. 1/3

c. 2/3

d. -2/3

Answers

Answer:

c. 2/3

Step-by-step explanation:

Since the line is going up to the right it is a positive slope. Therefore it can't be a or d.

The slope is 2/3 because to connect the dots you have to go up 2 and to the right 3.

Answers

Answer:

-10

Step-by-step explanation:

The equation would be -8 - (-10) = 2. When subtracting a negative, you are actually just adding a positive. It's like the two negative signs cancel each other out, so it would look more like -8 + 10 = 2. For the answer box, just put -10.

5x+4=5x+4 is it one solution, no solution, or infinite solutions?

Answers

Answer: infinite solutions

Simplifying
5x + 4 = 5x + 4

Reorder the terms:
4 + 5x = 5x + 4

Reorder the terms:
4 + 5x = 4 + 5x

Add '-4' to each side of the equation.
4 + -4 + 5x = 4 + -4 + 5x

Combine like terms: 4 + -4 = 0
0 + 5x = 4 + -4 + 5x
5x = 4 + -4 + 5x

Combine like terms: 4 + -4 = 0
5x = 0 + 5x
5x = 5x

Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x

Combine like terms: 5x + -5x = 0
0 = 5x + -5x

Combine like terms: 5x + -5x = 0
0 = 0

Solving
0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.

Infinite solutions

Try to solve this equation:

5x+4=5x+4

Move all the variables to the left:

5x-5x+4=4

Do you see what I see?

4=4

We end up with a true statement. 4 does indeed equal 4. Hope this helps!

I need help with this

Answers

Answer:

Step-by-step explanation:

∠5 = ∠1             {Alternate exterior angles are congruent}

8x - 19 = 7x - 3

Add 19 to both sides

8x = 7x - 3 + 19

8x = 7x + 16

Subtract 7x from both sides

8x - 7x = 16

   x = 16

∠5 = 8x - 19

    = 8*16 - 19

    = 128 - 19

 ∠5 = 109

∠5 + ∠4 = 180     {linear pair]

109 + ∠4 = 180

         ∠4 = 180 - 109

∠4 = 71°

how to use union in the real world?​

Answers

Answer:

To overcome such type of real world problems we use union. Unlike structures union occupies single memory location to store all its members. So, unions are helpful when you want to store value in single member from a set of members. Size of union is defined according to size of largest member data type.

Step-by-step explanation:

In union, all members share the same memory location. For example in the following C program, both x and y share the same location. If we change x, we can see the changes being reflected in y. #include <stdio.h> // Declaration of union is same as structures.

of the bill was for labor costs. How much was the total bill if the cost of the labor was $79.50? Let b = the amount of the total bill.

Which equation and solution is correct?
Five-thirds b = 79.50, and the total bill was $47.70.
Three-fifths (79.50) = b, and the total bill was $127.20.
Five-thirds b = 79.50, and the total bill was $212.00.
Three-fifths (b) = 79.50, and the total bill was $132.50.

Answers

Answer:

132.50

Step-by-step explanation:

3/5b = 79.50

b = (79.50) / (3/5)

b = 79.50 * 5/3

b = 397.50/3

b = 132.50

132.50 is the total bill
