Step-by-step explanation:

Answer: x=2 and y=−1

Step-by-step explanation:

5x+7y=3for x:

5x+7y=3

5x+7y+−7y=3+−7y(Add -7y to both sides)

5x=−7y+3

x= −7/ 5 y+ 3 /5

Substitute −7 /5 y+ 3 /5  for x in2x+3y=1:

2( −7/ 5 y+ 3 /5 )+3y=1

1 /5 y+ 6 /5 =1(Simplify both sides of the equation)

1 /5 y= −1 /5

y=1

Substitute −1 for y in x

−7 /5 y+ 3 /5 : x=

x=2

x=2(Simplify both sides of the equation)

Step-by-step explanation:

the angles 2 and 6 are corresponding meaning that they have the same value.

Answer:

In contrast, linear equations can describe values that are negative, zero or positive. As a result, the range of an absolute value function is zero and all positive numbers, while the range of a linear equation is all numbers.

The function inside the absolute value is NOT linear, therefore the graph contains curves.

Answer:

10.6^ -14

Step-by-step explanation:

The solution of the expression (9.6x10⁻⁸) + (2x10⁻¹⁵) is 9.6 x 10⁻⁸.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

The given expression will be solved as:-

E =  (9.6x10⁻⁸) + (2x10⁻¹⁵)

First, multiply the numbers and convert them into decimal form now add both the numbers and again write in the scientific form.

E =  9.6 x 10⁻⁸.

Therefore, the solution of the expression (9.6x10⁻⁸) + (2x10⁻¹⁵) is 9.6 x 10⁻⁸.

Answer:

120°

Step-by-step explanation:

The angle next to the x will be 40° due to the alternate angles so

x + 40° + 20° = 180° { being linear pair }

x + 60° = 180°

x = 180° - 60°

x = 120 °

Hope it will help :)

Answer:

120˚

Step-by-step explanation:

Since the two lines are parallel, they are alternate angles

So that means that the angle next to x must be 40˚

So 40 + 20 + x = 180 (since it's half a circle)

60 + x = 180

x = 120
