Answer:
14 - 8i
Step-by-step explanation:
The simplified expression is 14 - 8i.
Given is an expression (2 - 3i)(4 + 2i), we need to simplify it,
To simplify the expression (2 - 3i)(4 + 2i), we can use the FOIL method, which stands for First, Outer, Inner, Last.
First, we multiply the first terms of each binomial:
2 x 4 = 8.
Outer, we multiply the outer terms of each binomial:
2 x 2i = 4i.
Inner, we multiply the inner terms of each binomial:
-3i x 4 = -12i.
Last, we multiply the last terms of each binomial:
-3i x 2i = -6i².
Now, simplify the expression:
8 + 4i - 12i - 6i².
Since i² is defined as -1, we can substitute it:
8 + 4i - 12i - 6(-1).
Simplify further:
8 + 4i - 12i + 6.
Combine like terms:
14 - 8i.
Therefore, the simplified expression is 14 - 8i.

Answer:
B. {(-3, 4), (-8,0), (3, -8), (-3, -4)}
Step-by-step explanation:
B. is not a function because the x's repeat in this one.
If the x's repeat then it is not a function.
{(-3, 4), (-8,0), (3, -8), (-3, -4)}
The -3 repeats so it is not a function.
Y can repeat, but x cannot.

Find the value of f(7) if f(x) = x - 10.
The value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = x -10
The above function represents the linear function.
To find the value of f(7) plug x = 7 in the function.
f(7) = 7–10
f(7) = -3
Thus, the value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.

Answer:
$5.77
Step-by-step explanation:
Given expression:
1.8s + 0.65b
where,
s = the number of pounds of strawberries
b = the number of pounds bananas
If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas
s = 2.7 pounds
b = 1.4 pounds
how much did he spend?
1.8s + 0.65b
= 1.8(2.7) + 0.65(1.4)

Answer:
y=1/2x+5
Step-by-step explanation:
the y intercept is headed for five so we can cross off y=1/2x+2 and the slope is the flat to be 2x it has to be a slope of 1/2 it's much closer.
The only logical answer is y=1/2x+5

Answer:
B makes most sense.
Step-by-step explanation:
In a graph, x represents the number of months since a
business opened, and y represents the total amount of
money the business has earned. The following three
points are from the graph:
(2, 1990) (5, 4225) (9, 7205)
Find the slope and y-intercept. Explain what each
represents.
Answer:
My answer: To find the Slope the first we would need to use is the Slope-Intercept Formula. Y=mx+b. So 7205-4225=2980 and 9-5=4 So then you have to divide 2980/4=745 So the slope is 745. To find the Y-Intercept (b) we need to use the formula again. 4225= 745(5)+b so 745x5=3725 so we subtract on both sides 3725 is cancelled so 4225-3725=500 So the y-intercept is 500
Sample Response: The slope of this scenario is 745. The slope represents the profit made each month.

A peach pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice of pie that contained exactly 5 peaches, what wqs the angle measure of the slice to the nearest tenth of a degree?
Answer:
138.5°
Step-by-step explanation:
A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.
Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.
Joe ate one slice of pie that contained exactly 5 peaches, hence:
Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°
Angle measure of slice = (5 / 13) * 360°
Angle measure of slice = 138.5°

Answer:
8.) c
9.) d
10.) d
Step-by-step explanation:
8.) These are same side interior angles so they have a different measures that equal up to 180.
75 + 4x - 9 = 180 (collect like terms)
4x + 66 = 180 (subtract 66 on both sides)
4x = 114 (divide by 4 on both sides)
x = 28.5
9.) 8x -14 and 5x + 34 are alternate exterior angles so the equal the same measure.
8x - 14 = 5x + 34 (add 14 on both sides)
8x = 5x + 48 (subtract 5x on both sides)
3x = 48 (divide by 3 on both sides)
x = 16 NOW PLUG IN TO 8x - 14 to find y
8(16) - 14 + 5y + 16 = 180 (distribute and collect like terms)
130 + 5y = 180 (subtract 130 on both sides)
5y = 50 (divide by 5 on both sides)
y = 10
10.) They have the same measure they are alternate exterior angles
16x + 22 = 134 (subtract 22 on both sides)
16x = 112 (divide by 16 on both sides)
x = 7

Ducklings cost $15 each. Chicks cost $12 each. You have $60 to spend on poultry
Answer:
If your question is how much money you have after you purchase a duckling and a chick, your answer would be $33. It seems to me like you posted the question without finishing it. I'm guessing you were about to mention how many ducklings and chicks you were going to buy and how much money you would have leftover for the poultry.
Step-by-step explanation:
To solve your problem you must add what you're buying and then subtract from your original amount.
For example: if you want one duckling and one chick and you would like to know how much money you have leftover to buy poultry. $15 + $12= $27 dollars in all. Then, you will subtract $27 dollars from $60, this way you know how much money you will have left in order to buy the poultry. $60 - $27= $33.

The length of base of the triangle is given by BC = 7 feet
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle BC = a
Let the hypotenuse of the triangle be c = 25 feet
Let the height of the triangle be b = 24 feet
And , For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
So , the base BC = √ ( 25 )² - ( 24 )²
The base of the triangle BC = √ ( 625 - 576 )
The base of the triangle BC = √ ( 49 )
The base of the triangle BC = 7 feet
Hence , the length of base of triangle is 7 feet
