Answer:
-1 -9i, where a = -1 and b = -9
Step-by-step explanation:
1st step is to open up the brackets. Since there's a (-) in front of the second bracket, we have to multiply every term by -1, so positive becomes negative, negative becomes positive etc.
4-i-5-8i
Then we collect like terms.
-1 -9i
This is the answer. It looks wrong since the variables are 'positive' in a +bi, but you have to remember that a variable can be represented as a, but its actual value could be negative, in this case -1. This is the same with b, as b could be the same as -9.
This is an expression, so we can't multiply everything by -1 to make it 'look right'. You can only multiply by -1 or 'alter' the terms when the expression equates to something.

Rachel is planning to run an average of 6.4 miles over three consecutive days. On the first
day, she ran 6.6 miles, and on the second day, she ran 6.5 miles. What is the maximum
number of miles Rachel can run on the third day without going over the planned average of
6.4 miles per day?
The maximum number of miles Rachel can run on the third day without going over the planned average of 6.4 miles per day is 6.1 miles.
Maximum number of miles:Let x represent the maximum number of miles
Formulate
6.6+6.5+x÷3=6.4
Hence:
6.6+6.5=6.4×3
13.1+x=19.2
x=19.2-13.1
x=6.1 miles
Inconclusion the maximum number of miles Rachel can run on the third day without going over the planned average of 6.4 miles per day is 6.1 miles.

A scuba diver descends below the surface of a lake at a rate of 12 feet per minute. What integer represents the depth of the diver after 4 minutes?
Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.
What is the rate of change?The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;
Rate of change = Depth/time
Making depth the subject of formula, we have:
Depth = Rate of change × time
Substituting the given parameters into the formula, we have;
Depth = 12 × 4
Depth = 48 feet.

The Point of Concurrency made from medians is a(n):
Answer:
centroid
Step-by-step explanation:
find the value of x.
Answer:
2
Step-by-step explanation:
Since they are similar triangles then the ratio will be the same on all sides.
You know the one side 5 is the same ratio to 5x so you multiply x to all sides of the little triangle to get the value of the equivalent side in the big one.
so the missing side x times x will equal the big size of the bigger triangle which is 4
x times x = 4 can only be 2
Fill in the table using this function rule.

x squared -8x+14=2x-7
Answer:
x = 3 or x = 7
Step-by-step explanation:
X² - 8x + 14 = 2x - 7
x² - 8x + 14 - 2x + 7 = 0
Now we have a quadratic equation ;
x² - 10x + 21 = 0
-3 and - 7 gives a sum of - 10 and a product of 21
x² - 3x - 7x + 21 = 0
x(x - 3) - 7(x - 3) = 0
(x - 3) = 0 or (x - 7) = 0
x = 3 or x = 7

1.Could 18 in, 6 in, and 13 in, form a triangle?
2. Could 34 km, 27 km, and 58 Km, form a triangle?
3. Could 29 ft, 38 ft, and 9 ft, form a triangle?
4. Could 12 cm, 12 cm, and 25 cm, form a triangle?
5. Could 31 yd, 14 yd, and 19 yd, form a triangle?
Answer:
1. yes
2. yes
3. no
4. no
5. yes
Step-by-step explanation:
The questions you're asking relate to the Triangle Inequality Theorem, which states that the two smallest sides (ex. 6 and 13) have to be of greater value than the largest side (ex. 18)
1. 6+13>18
2. 34+27>58
3. 29+9=38 (since the value of the two smallest sides are equal, it does not apply to the Triangle Inequality Theorem, and therefore won't be a triangle)
4. 12+12<25
5. 19+14>31

Jacob makes a scale drawing for a crate with a scale factor of 1:20 the dimitions of his scale drawing is 3 in long and 2 in wide the bulder creates a scale drawing of the crate with the scale factor of 1:10. What are the dimitions of the builders drawing?
Answer:
6 in long ; 4 in wide
Step-by-step explanation:
With a scale of 1:20
Scaled drawing is 3 in long ; 2 in wide
Actual dimension :
Length = 20 * 3 = 60 in
Width = 20 * 2 = 40 in
Hence, to make a scaled drawing using 1 :10
Dimension :
Length = (1/10) * 60 = 6 inches
Width = (1/10) * 40 = 4 inches
Determine whether the given value of the variable is a solution to the inequality 3b + 2 < 14 when b = 4
Answer:
I dont think it that would be the solution because 14 has to be greater and not equal.
Step-by-step explanation:
3(b) + 2 < 14
3(4) + 2 < 14

Determine one number that summarizes the 5 numbers
First, one can use the mean to get the summary of the numbers.
The mean is calculated as:
[tex]Mean = \frac{Sum\ of\ observation}{Number\ of\ observation}[/tex]
[tex]Mean = \frac{10 + 15 + 11 + 13 + 11}{5}[/tex]
[tex]Mean = \frac{60}{5}[/tex]
[tex]Mean = 12[/tex]
Another number that summarizes the numbers is the mode of the distribution.
[tex]Mode = Highest\ Occurring\ Value[/tex]
So, in this case:
[tex]Mode = 11[/tex]
Hence, you can either use 11 minutes or 12 minutes.
