5 - i

Question 2

(3 – 5i) – (–2 – i)
3 - 5i + 2 + i
5 - 4i

Question 3

Solve 4(x + 2) = 20

KiRa [710]

Answer:

x = 3

Explanation:

$\sf 4(x + 2) = 20$

$\sf 4x + 8 = 20$

$\sf 4x = 20 - 8$

$\sf 4x = 12$

$\sf x = \frac{12}{4}$

$\sf x = 3$

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3

What is the constant of proportionality of y to x?

AleksAgata [21]

Answer:

2.5

Step-by-step explanation:

We are given a graph with a positive slope where the value of y increases when the value of x increases.

For the given graph, we are to find the constant of proportionality of y to x which is the slope of the given line.

We know the formula of the slope = $\frac{y_2-y_1} {x_2-x_1}$

Substituting the given values in the formula:

$\frac{15-10}{6-4} = \frac{5}{2} = 2.5$
