Answer:

Questions:

#1) one complex solution

#2) two solutions

#3) one complex solution

#4) one solution

Step-by-step explanation:

1) x² = -100;      x = 10i

2) 5x² = 1;         x = ±[tex]\sqrt{1/5}[/tex]

3) 6x² + 6 = 0;    x = i²

4) 7(x² + 6) - 42 = 0;    x = 0

Answer:

(0, 2)

Step-by-step explanation:

Both the lines are intersecting each other at point (0, 2)

So, the solution to the system of equations would be (0, 2)

Answer:

C.) 87 years

Step-by-step explanation:

I've taken the test! Hope this helps! ;)

The number of years for her to have at least $100,000 if interest is compounded continuously is 90

The given parameters are:

Amount, A = 100,000

Principal, P = 100

Rate, r = 8%

Amount is calculated using:

A = P * (1 + r)^t

So, we have:

100000 = 100 * (1 + 8%)^t

Divide by 100

1000 = (1 + 8%)^t

Evaluate the sum

1000 = 1.08^t

Take the logarithm of both sides

log(1000) = log(1.08)^t

Apply the law of logarithm

log(1000) = tlog(1.08)

Solve for t

t = log(1000)/log(1.08)

Divide

t = 89.7

Approximate

t = 90

Hence, the number of years is 90

Step-by-step explanation:

To find the value of x in a triangle, you need to subtract the sum of the two angles from 180 degrees. Know that the sum of all the angles of a triangle will always equals 180 degrees. Then write down the difference of subtracting the sum of the two angles from 180 degrees and that would equal the value of x.

I hope this helped in some way, if it didn't, im so sorry.

f(x) - g(x)

= 5x² - 2x + 7 - (- 2x² + 6x + 3) ← distribute parenthesis

= 5x² - 2x + 7 + 2x² - 6x - 3 ← collect like terms

= 7x² - 8x + 4

Answer: 350km

Step-by-step explanation:

Since we are informed that the scale of map is 1cm : 70km. Therefore, the actual distance between towns that are 5cm apart on the map will be:

= 5 × 70km

= 350km

Therefore, the answer is 350km

Answer:

$613.6

Step-by-step explanation:

Given data

Monthly income = $550

Plus commision =4% of sales

Sale for the month= $590

Let us find the commission earned

4/100*590

=0.04*590

=$23.6

Hence the net income for that month is

=23.6 +590

= $613.6

Step-by-step explanation:

Answer:

Negative

Step-by-step explanation:

On the line, we see that a = 0.5 and b is after -1. a + b will be negative because anything after -1 added to .5 will be negative.

Example:

-1 + .5 = -.5

-2 + .5 = -1.5

-3 + .5 = -2.5

Answer: Negative

Step-by-step explanation: the b we can see is far away from  -1 that means its around - 2 and if we were to add 0.5 and - 2 we would get -1.5
