Option D would be the correct answer.
Set the equation inside the absolute value brackets equal to 12 and -12, so you will end up with two answers.
7x+2=12 gives you 10/7
7x+2=-12 gives you -2.
So your answers are 10/7 and -2
Answer:
x-int: (-40, 0)
y-int: (0, 15)
General Formulas and Concepts:
<u>Algebra I</u>
- The x-intercept is the x value when y = 0. Another way to reword that is when the graph crosses the x-axis.
- The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.
Step-by-step explanation:
According to the line on the graph, it passes the x-axis at x = -40 and it passes the y-axis at y = 15.
Therefore, our x-int is (-40, 0) and our y-int is (0, 15)
Answer:
The values of x and y are x = 5 and y = -13 ⇒ B
Step-by-step explanation:
If the complex numbers are A = (a + bi) and B = (c + di), then
A + B = (a + c) + (b + d)i
- (b + d) is the imaginary part
Let us solve the question
∵ (x + yi) + (4 + 9i) = 9 - 4i
→ Add the real parts and the imaginary parts on the left side
∵ x, 4 are the real parts, and y and 9 are the imaginary parts
∴ (x + 4) + (y + 9)i = 9 - 4i
→ Compare the two sides, and equate the like terms
∵ 9 is the real part and -4 is the imaginary part
∴ x + 4 = 9
→ Subtract 4 from both sides
∴ x + 4 - 4 = 9 - 4
∴ x = 5
∵ y + 9 = -4
→ Subtract 9 from both sides
∵ y + 9 - 9 = - 4 - 9
∴ y = -13
