Answer: “6b”

Step-by-step explanation:

The graph of equation is in image.

When a linear equation is graphed, it always results in a straight line because each term has an exponent of 1. This is why it is referred to as a "linear equation."

There are linear equations with one and two variables, respectively.

Given equations 2x + 3y = 5

4x - 5y = -1

for equation 1

2x + 3y = 5

x    1     -2    4

y    1      3    -1

coordinates for equation 2

4x - 5y = -1

x    1     2    -4

y    1     1.8   -3

and the intersection point of equation is (1, 1)

Hence the graph of equation is intersecting at (1, 1).

Answer:

7. Inscribed angle

Step-by-step explanation:

7. Inscribed angle

8.

y° = 70°

z° = 140°

8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.

Therefore, y° = 70°

Measure of central angle is two times the measure of the inscribed angle.

Therefore,

z° = 2* 70° = 140°

The amount of money when she worked one week she worked 36 regular hours plus 8 holiday hours will be $760.24.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Rita is a nurse her regular rate is $14.62 per hour. She is paid double-time (two times the hourly rate) for holidays.

Then the amount of money when she worked one week she worked 36 regular hours plus 8 holiday hours will be

⇒ $14.62 x 36 + $14.62 x 2 x 8

⇒ $526.32 + $233.92

⇒ $760.24

The amount of money when she worked one week she worked 36 regular hours plus 8 holiday hours will be $760.24.

k= 4/3

Step-by-step explanation:

distribute 9     9k- 18=-6

add 18 to both sides  9k= 12

divide by 9

The value of k is 4/3 or 1.334.

A statement that supports the equality of two expressions that are connected by the equals sign "=" is an equation.

An equation is a condition on a variable in algebra. It only holds true for a specific value of the variable.

Polynomial equations and linear equations are two prominent families of equations that algebra takes into account.

Given equation

9(k - 2) = -6

9k - 18 = -6

add 18 both sides

9k - 18 + 18 = -6 + 18

9k = 12

k = 12/9 =4/3 = 1.334

Hence the value of k is 4/3 or 1.334.

Answer:

46 units.

Step-by-step explanation:

To find the perimeter, you need to add up all the sides. Knowing this, we can set up an equation to solve for y.

2(5y + 1) + 2(4y + 3) = 170

10y + 2 + 8y + 6 = 170

18y + 8 = 170

18y = 162

y = 9

Now that we know y = 9, we can solve for vw.

vw = 5(9) + 1

vw = 45 + 1

vw = 46

Therefore, line vw is 46 units.

Answer: VW=11

4y+3=5y+1
