Simplify the following expression
(-1+i)+(21+5i)
A. 0 -1+ (1+21) + 5i
B. 20+68
C. 20+5i
D 22+6i
Answer:
i would say the answer is 20 + 6i but thats not an answer
-1 + 21 = 20
and
i + 5i = 6i
so
20 + 6i

The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 is graphed below. On a coordinate plane, 2 lines intersect at (0, negative 1). What is the solution to the system of equations? (0, –1) (–1, 0) (0, 1) (1, 0)
Answer:
0, -1
Step-by-step explanation:
trust me I just took the exam on edge 2020
The solution to the given system of equations will be (0, -1). which is the correct option (B).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 which is given in the question.
y = 2x - 1 ....(i)
y = -4x - 1 ....(ii)
Substitute the value of equation (i) in equation (ii) and solve for variable x :
2x - 1 = -4x - 1
Rearrange the terms of variable "x" and combine them,
2x + 4x = -1 + 1
6x = 0
x = 0
Substitute the value of x = 0 in equation (ii) and solve for variable y :
y = -4(0) - 1
y = -1
Therefore, the solution to the given system of equations will be (0, -1).

Michelle's car needs repairs. The mechanic said it will be $144 for parts plus $80 an hour to repair the car. How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?
Answer:
3 hours
Step-by-step explanation:
Total cost = 144 + 80h
Where h = number of hours
How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?
384 = 144 + 80h
Subtract 144 from both sides
384 - 144 = 144 + 80h - 144
384 - 144 = 80h
240 = 80h
Divide both sides by 80
h = 240 / 80
= 3
h = 3 hours

how do you find the growth rate (like the percentage of growth each week) for an exponential function when you only have the starting value, the amount of weeks and the ending value???? (for example, a plant starts at (0,2) when it is planted, after 18 weeks it is 20 inches) how do you find out the percent of growth each week to plug it into an equation???
9514 1404 393
Answer:
the n-th root of the ratio of ending to starting values, less 1
Step-by-step explanation:
When I have starting and ending values over a time period, I usually use those directly in the exponential equation. If you're asked for a percentage growth rate, then you have to convert the growth factor to a growth rate.
__
The exponential equation can be written ...
f(t) = (initial value) × ((final value)/(initial value))^(t/(time period))
In your example case, this would be ...
f(t) = 2 × (20/2)^(t/18)
f(t) = 2(10^(t/18)) . . . . . . simplified
__
To convert this to the form ...
f(t) = 2(1 +(growth rate))^t
recognize that ...
(1 +(growth rate)^t = (10^(1/18))^t
So, you need to find the value of ...
10^(1/18) = 10^(1/18) ≈ 1.13646 = 1 + 13.646%
Then the growth rate is about 13.6% each week.
__
Sometimes, you want to use this in the form ...
f(t) = (initial value)×(1 + (growth rate))^t
and sometimes you want the form ...
f(t) = (initial value)×e^(kt)
When you solve for k, you find it is ...
k = ln(1 + (growth rate)) . . . . . . . . where ln(x) is the natural logarithm of x
Here, that is ...
k = ln(10^(1/18)) = ln(10)/18 ≈ 0.12792
__
Your final growth equation could be any of ...
f(t) = 2(10^(t/18)) . . . . . . . my personal favorite, as no rounding is involved
f(t) = 2(1.13646^t)
f(t) = 2e^(0.12792t)

You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.
Answer:
this is a right angle triangle.
which means that we can use hypotenuse theorem to solve it.
the hypotenuse theorem:-
a^2 +b^2 =c^2
where a and b are the sides opposite to the hypotenuse.
[(the longest side) the longest side of the triangle is always opposite to the right angle]
so...
a = 24
b = 7
a^2 + b^2 = c^2
24^2 + 7^2 = c^2
576 + 49 = c^2
625 = c^2
don't stop here, you could lose marks. I have seen my classmates do this silly and small mistake and lose 1/2 a mark.
√625 = c
25 = c
thus the length of the third side is 25.

divide both sides by 1/2
1/2x÷1/2=5÷1/2
x=5×2/1

PLEASE HELP!! Determine whether the triangles are similar. If similar state how (AA~,SSS~, or SAS~), and write a similarity statement
Answer:
Yes they are similar because of SAS similarity
Step-by-step explanation:
the side lengths are proportional to each other, and the angle in the middle of the sides is the same size, therefore it has Side Angle Side (SAS) similarity.
ΔTSR ~ ΔFEG by the SAS Similarity Theorem
What is the SAS Similarity Theorem?SAS Similarity Theorem states that two triangles with two pairs of proportionate sides and a pair of included angle are similar to each other.
In the image given, the two triangles have:
Two pairs of proportional sides - TS/FG = TR/FE = 3.A pair of congruent included angles - ∠T ≅ ∠F.This means they are similar by the SAS Similarity Theorem.
Therefore, ΔTSR ~ ΔFEG by the SAS Similarity Theorem.
