Answer:

6 - 4i

Step-by-step explanation:

-4 + i = 10 - 5i

<u>+4       +4      </u>

i = 14 + 5i

<u>-5i      -5i      </u>

-4i = 14

i = -3.5

In 1992​, there were 41 comma 984 shopping centers in a certain country. In 2002​, there were 48 comma 225. ​(a) Write an equati
Illusion [34]

Answer:

Step-by-step explanation:

The equation expressing the number y of shopping centers in terms of the number x of years after 1992 will be LINEAR in nature

The standard equation is expressed as;

y = mx+c

m is the slope

c is the intercept

If in 1992​, there were 41,984 shopping centers in a certain country and in 2002​, there were 48,225 we can express this as coordinate points

(0, 41984) and (10, 48,225)

Get the slope

m = 48,225-41,984/10-0

m = 6241/10

m = 624.1

Get the intercept, substitute m = 624.1 and the point (0,48225) into the formula y = mx+c

48225 = 624.1(0)+c

48225 = 0+c

c = 48225

Get the required equation

y = 624.1x+48225

What is the y-intercept of a line that passes through the points (5, -6.5) and (-12, 2)?
n200080 [17]

Answer:

y-intercept = -4

Step-by-step explanation:

equation of a line: y=mx+b

two points given are (5, -6.5) and (-12, 2)

first we can easily find value of m or the slope, by using the slope formula. the value of m=-0.5.

formua to find m: \frac{2-(-6.5)}{-12-5}= -0.5

to find the value of b (the y-intercept), we need to plug in a y and x value, we are given 2 ordered pairs, you can use either one and plug x-value in for x and the y-value in for y.

if i plug in (5, -6.5), my equation looks like this: -6.5=5(-0.5)+b

then you just solve for b and it turns out to be -4.
