90 dollars in 6 weeks so if you divide them you get 15 so she make 15 dollars a week so do 150 divided by 15 and you get 10
Answer:10 or A
Step-by-step explanation:
90 ÷ 6 = 15
150 ÷ 15=
10

Step-by-step explanation:
In the complex plane, the rectangular coordinates (x, y) represent a complex number. Which statement explains why polar coordinates (r, θ) represent the same complex number?
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction).
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction).
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction).
r is equivalent to StartRoot x squared + y squared EndRoot and θ is equivalent to Inverse tangent of (StartFraction x Over y EndFraction)
Answer:
The correct option is;
r = √(x² + y²)
θ = tan⁻¹(y/x)
Step-by-step explanation:
The rectangular coordinate of a complex number on the complex plane is given as (x, y)
Given that the complex number is represented by a point on the plane, we have;
The distance, r, of the point from the origin, (0, 0) is r = √(x² + y²)
The direction, θ, by which we rotate to be in line with the point on the complex number is given by tan⁻¹(y/x)
Complete the table below for the function y = -3x+7
Answer:
(x,y)--> (2,1), (4, -5), (7, -14), (9, -20), (11, -26)
Step-by-step explanation:
y = -3x + 7
substituting x-values in y= -3x + 7
x = 2
y= -3 × 2 + 7
= -6 + 7
= 1
x=4
y= -3 × 4 + 7
= -12 + 7
= -5
x=7
y= -3 × 7 + 7
= -21 + 7
= -14
x=9
y= -3 × 9 + 7
= -27 + 7
= -20
x=11
y= -3 × 11 + 7
= -33 + 7
= -26
The table for the linear relationship, y = - 3x + 7 is shown below
What is the equation of line?The equation of a straight line is a relationship between x and y coordinates, The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept.
Given that,
A equation of a line,
y = - 3x + 7
And Values of x,
2, 4, 7, 9, 11
Now, values of y for particular values of x
When x = 2
y = - 3 × 2 + 7
= 1
When x = 4
y = - 3 × 4 + 7
= -5
When x = 7
y = - 3 × 7 + 7
= - 14
When x = 9
y = - 3 × 9 + 7
= -20
When x = 11
y = - 3 × 11 + 7
= -26
The table for values of y
x: 2 4 7 9 11
y: 1 -5 -14 -20 -26

Before 2017, a smart phone manufacturer's phones had a diagonal length of 5.8 inches and an aspect ratio
of 16:9. In 2017, they released a new phone that also had a 5.8-inch diagonal length, but an aspect ratio of
18.5:9. Some customers complained that the new phones had a smaller screen. Were they correct? If so,
how much smaller was the new screen compared to the old screen?

Step-by-step explanation:
Use substitution to determine the solution of the system of equations. Write the solution as an ordered pair.
x + 2y = 14
y = 3x − 14
The value of x is 6 and the value of y is 4 for the expressions.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the two linear equations are x + 2y = 14 and y = 3x − 14. Equations can be solved as below,
x + 2y = 14
y = 3x − 14
Substitute the value of y in the first equation,
x + 2y = 14
x + 2 ( 3x - 14 ) = 14
x + 6x - 28 = 14
7x = 42
x = 6
The value of y will be calculated as:-
y = 3x - 14
y = ( 3 x 6 ) - 14
y = 18 - 14
y = 4
